SOP 1: Soil Boring Drilling and Abandonment

I. PURPOSE AND SCOPE

«

The purpose of this guideline is to describe methods to obtain samples of subsurfacesoil and then backfill boreholes to the surface. .

H. EQUIPMENT AND MATERIALS

• Drilling rig or tripod rig

• Hollow-stem augers (4V4-inch ID)

• Split-spoon samplers

• Downhole compacting tool (e.g., a pipe with a flat plate attached to thebottom)

• Cement

• Bentonite

• Hand augers, stainless steel

III. PROCEDURES AND GUTOELINES

Before sampling begins, equipment will be decontaminated according to theprocedures identified in SOP 6: Decontamination of Drilling Rigs and Equipment.

A H 3 0 I O I I

The location to be sampled is cleared of debris and trash, and the location is notedin the logbook.

Continuous-fight hollow-stem augers with an inside diameter of at least 4.25 nichesare used. The use of water or other fluid to assist in .hollow-stem drilling will beavoided.

The bit of the auger is placed on the ground at the location to be drilled and then

turned with the drilling or soil-coring rig. For split-spoon sampling, the auger isadvanced to a depth just above the top of the interval to be sampled.

Once the auger has been advanced full depth and the last sample obtained, the soilsremoved from the boring will be screened using a portable volatile organics detector.

Soils registering less than 10 ppm in a headspace screening will be returned to theborehole. Soil returned to the borehole will be compacted with the augers in 2-footlifts. The remainder of the borehole is to be grouted to the surface with bentonite-cement grout. The remaining soils are to be drummed and managed as described inSOP 7.

The cement-bentonite grout will be installed continuously in one operation from thebottom of the space to be grouted to the ground surface. When installing grout insoil borings, the grout will be installed through the augers before the augers areremoved.

Samples will be collected from the soil borings at 2-foot intervals. The soil sampleswill be collected from the surface continuously to the water table. Because some ofthe soil samples are being collected for chemical analysis, decontaminated stainlesssteel split-spoon samplers will be used for sample collection. The split-spoonsamplers will be decontaminated according to the procedures outlined in SOP 6.Sample collection will follow the general procedures outlined in SOP 4.

A B 3 0 I O I 2

A tripod drilling rig will be required for boring installation under power lines and

adjacent to railroad tracks. A tripod drilling rig is generally a tripod equipped tocollect continuous samples using a hammer-driven sampler. The soil samplecollection will be the same as that outlined above, except that hollow-stem augersare not used to advance the borehole. Borehole collapse due to soft sediments mayoccur when collecting samples using a tripod drilling rig.

Soil samples will be collected at 1-foot intervals. The soil samples will be placed inclean jars and a headspace measurement of the volatile organics in each of the

samples determined. The headspace measurements will be used to identify the fourpotentially most-contaminated samples which will be submitted for analysis throughthe CLP.

IV. ATTACHMENTS

None.

V. KEY CHECKS AND PREVENTA1TVE MAINTENANCE

Check that the drilling rig or soil-coring rig is hi working order. Check that theborehole is grouted to the ground surface at the completion of drilling and sampling.

III. PROCEDURES AND GUIDELINES

A. Drilling Method

Continuous-flight hollow-stem augers with a minimum 6-inch inside diameter(ID) will be used to drill shallow monitoring well boreholes. Split-spoon

>

samples will be collected at selected intervals for chemical analysis and/orlithologic classification. Soil sampling procedures are detailed in SOP 4.

The use of water to assist hi hollow-stem auger drilling for monitoring wellinstallation will be avoided.

Hollow-stem augers, rods, split-spoon samplers, and other downhole drillingtools will be properly decontaminated prior to the initiation of drilling

. activities and between each borehole location. Split-spoon samplers andother downhole soil sampling equipment will also be properlydecontaminated before and after each use. SOP 6 details properdecontamination procedures.

Drill cuttings and decontamination fluids generated during well drillingactivities will be contained according to the procedures detailed in SOP 7.

B. Monitoring Well Installation

Shallow monitoring wells will be constructed through the inside of thehollow-stem augers, once the borehole has been advanced to the desireddepth. If the borehole has been drilled to a depth greater than that at whichthe well is to be set, the borehole will be backfilled with bentonite pellets ora bentonite-cement slurry to a depth approximately 1 foot below the intendedwell depth. Approximately 1 foot of clean sand will be placed on top of thebentonite to return the borehole to the proper depth for well installation.

A B 3 0 I O I 7

The appropriate lengths of well screen, nominally 10 feet (with bottom cap),

and casing will be joined watertight and lowered inside the augers to thebottom of the borehole. Centering guides will be placed around the wellcasing at the bottom of the screen; 5 feet from the top of the screen; and at

40 feet intervals above that.

Selection of the filter pack and well screen intervals for the shallowmonitoring wells shall be made in the field. Based on lithologic samplespreviously obtained at the site, and comparison with samples to be obtainedin the well borings, standard well screen slot of 0.010-inch and silica sandgradations conforming to Morie No. 1 are anticipated.

A primary sand pack (Morie No. 1) consisting of clean silica sand will beplaced around the well screen. The sand will be placed into the borehole ata uniform rate, in a manner that will allow even placement of the sand pack.The augers will be raised gradually during sand pack installation to avoidcaving of the borehole wall; at no time will the augers be raised higher than

the top of the sand pack during installation. During placement of the sand,the position of the top of the sand will be continuously sounded. Theprimary sand pack will be extended from the bottom of the borehole to aminimum height of 2 feet above the top of the well screen. A secondary,finer-grained, sand pack will be installed for a minimum of 1 foot above thecoarse sand pack. Heights of the coarse and fine sand packs and bentoniteseal may be modified hi the field to account for the shallow water table andsmall saturated thickness of the surficial aquifer.

A bentonite pellet seal at least 2 feet thick will.,be placed above the sandpack. The pellets will be placed into the borehole in a manner that willprevent bridging. The position of the top of the bentonite seal will beverified using a weighted tape measure. If all or a portion of the bentoniteseal is above the water table, clean water will be added to hydrate the

5 A I 3 0 I O I 8

bentonite. A hydration period of at least 30 minutes will be allowedfollowing installation of the bentonite seal.

Above the bentonite seal, an annular seal of cement-bentonite grout will beplacec. The cemem-bentonite grout will be installed continuously in oneoperation from the bottom of the space to be grouted to the ground surfacethrough a tremie pipe. The tremie pipe must be plugged at the bottom andhave small openings along the sides of the bottom 1-foot length of pipe.This will allow the grout to diffuse laterally into the borehole and not disturbthe bentonite pellet seal.

For monitoring wells that will be completed above-grade, a locking steelprotective casing set in a concrete pad will be installed. The steel protectivecasing will extend at least 3 feet into the ground and 2 feet above ground.The concrete pad will be square, approximately 3 feet per side. The concretewill be sloped away from the protective casing.

Guard posts may be installed in high-traffic areas for additional protection.Four steel guard posts will be installed around the protective casing, withinthe, edges of the concrete pad. Guard posts will be concrete-filled, at least2 inches in diameter!, and will extend at least 2 feet into the ground and3 feet above the ground. The protective casing and guard posts will bepainted with an epoxy paint to prevent rust.

For monitoring wells with flush-mount completions, Morrison 9-inch or12-inch 519 manhole cover with a rubber-sealed cover and drain will beinstalled. The top of the manhole cover will be positioned approximately1 inch above grade. A square concrete pad, approximately 3 feet per side,will be installed as a concrete collar surrounding the road box cover, and will

slope uniformly downward to the adjacent grade. --The road box and

A B 3 0 I O I 9

installation thereof will be of sufficient strength to withstand normalvehicular traffic.

Concrete pads installed at all wells will be a minimum of 6 inches below

grade and 6 inches above grade. The concrete pad will taper to 6-inchthickness at the edge. Protective casing, guard posts, and flush mounts willbe installed into this concrete.

Each well will be properly labeled on the exterior of the locking cap orprotective casing with a metal stamp indicating the permanent well number.

C. Well Development

Well development will be accomplished using a combination of surgingthroughout the well screen and pumping, until the physical and chemicalparameters of the discharge water that are measured in the field havestabilized and the turbidity of the discharge water is substantially reduced.

Fine-grained materials in the surficial'aquifer at the site, may not allow lowturbidity results to be achieved.

The surging apparatus will include two surge blocks separated byapproximately 2 feet of coarsely slotted pipe. The lower surge block will besolid; the upper surge block will be open and attached to riser pipe leading tothe ground surface. Water will be pumped continuously from the surge blockscreened interval throughout the surging process. The pumping will beaccomplished by airlift induction methods or using a centrifugal pump orequivalent.

Well development will begin by surging the well screen, starting at the

bottom of the screen and proceeding upwards, throughout-the screened zone.

£#301020

Following surging, the well will be pumped to remove the fine materials thathave been drawn into the well. During pumping, measurements of pH,temperature, and specific conductance will be recorded.

Development will continue by alternately surging and pumping until thedischarge water is free from sand and silt, the turbidity is substantiallyreduced, and the pH, temperature, and specific conductance have stabilized atregional background levels, based on historical data. Development willcontinue for a minimum of 30 minutes.

Well development equipment will be decontaminated prior to initial use andafter the development of each well. Decontamination procedures are detailedin SOP 6. Water generated during well development will be contained andmanaged as detailed in SOP 7.

in. PROCEDURES AND GUIDELINES

A. Drilling Methods

Boreholes for intermediate and deep monitoring well installation will bedrilled in several stages.

Coring, mud rotary drilling, and surface casing installation procedures aredetailed below in separate sections.

. 1. Hollow Steam Auger Drilling

Hollow stem auger drilling techniques will be used to drill boreholesin the intermediate wells for installation of surface isolation casing.8-inch minimum ID HSA will be used to drill the borehole into theaquitard. The boring will be concurrently sampled to confirmidentification of the aquitard. Sampling procedures and frequency areoutlined in the SAP and in SOP 4.

\

The use of water or other fluid to assist in hollow steam drilling is tobe avoided.

The bit of the auger is placed at the ground surface and then turnedwith the soil coring rig. To collect split spoon samples, the auger isadvanced to the top of the sampling depth, and the split-spoon samplecollected from below the auger head. The split spoon is advancedthrough repeated blows from a 140- or 30-pound hammer droppedfrom a height of 30 inches.

A - R 3 0 I 0 2 6

Soil brought to the surface on the outside of the augers should be

containerized at a convenient space away from the working area. Soilmay be stored on plastic sheeting and containerized at the completionof activities at the well cluster.

2. Rotary Drilling

Wet rotary drilling techniques will be employed for installation of

isolation casings and wells in each of the intermediate and deepmonitoring wells. Drilling fluid consisting of water (wet rotary) ofbentonite mud (mud rotary) will be recirculated to bring drill cuttings

to the surface and advance the borehole.

Where the borehole is being advanced from ground surface to theaquitard layer for placement of a 10-inch ID surface casing, theborehole will have a minimum diameter of 14 inches. The boreholewill extend a minimum of 2 feet into the aquitard layer for seating of

the surface casing.

Where the borehole is being reamed out for monitoring wellinstallation through an installed 6-inch intermediate casing, theborehole will have a diameter of 5-7/8 inches.

The bit, drill rods, and other borehole rotary drilling equipment willbe decontaminated prior to the initiation of drilling and between each

borehole location, in accordance with the decontamination proceduresdetailed in SOP 6. Prior to the continuation of rotary drilling inboreholes where a surface casing has been installed, the bit, drill rods,and other downhole rotary drilling equipment will be thoroughlydecontaminated before being inserted into the borehole.

AR.30I027

Drill cuttings and decontamination fluids generated during rotary

drilling activities will be contained according to the proceduresdetailed in SOP 7.

3. Wet Rotary Drilling

Drilling fluids used in wet rotary drilling will consist of potable waterand no additives. The drilling fluid shall be recirculated through theborehole to bring drill cuttings up to the surface and advance theborehole. Drilling mud will be recirculated through the boreholefrom a portable settling basin with a minimum of two vertical settlingbaffles. The settling basin and recirculation system will be of suitableconstruction to avoid leakage or spillage of drilling fluid onto theground adjacent to the borehole.

Wet rotary drilling may not be suitable for all materials at the site.Borehole collapse, non-recovery of drill cuttings, or non-recovery ofdrilling fluids may indicate that drilling using wet rotary techniques isinappropriate. Mud rotary drilling may be substituted for wet rotarytechniques for well installation following discussion with projectmanagement personnel. Mud rotary techniques are not the preferredwell installation techniques of EPA Region III, use of this method isto be considered a last resort after evaluation of the impacts of othertechniques.

4. Mud Rotary Drilling

The water used to create the drilling mud will be potable; a sample ofthe drilling mud will be collected for contaminant analysis prior to thestart of drilling. Only pure, additive-free bentonite will be used toproduce the drilling mud.

6 A R 3 0 I 0 2 8

5. Surface Casing Installation

Surface casing will be constructed of 10-inch or 6-inch ID steel witha minimum wall thickness of 0.20 inches. Casing lengths will be

connected by threaded connections sealed with Teflon tape. The steelcasing and threaded couplings must be free of paint, varnish, or

coatings of any kind, both inside and outside. Threaded connectionsmust be free of any oils or grease. The casing may abe welded

provided the welds meet the Standards of the American WeldingSociety. Surface casing will be decontaminated prior to installation inaccordance with the procedures detailed in SOP 6.

The 10-inch ID surface casing will be installed in a minimum 14-inch

diameter borehole, drilled at least 2 feet into the aquitard layer. Priorto inserting the surface casing into the borehole, drilling fluidcirculation will be continued until the drill cuttings have been

substantially removed from the borehole.

The surface casing will be installed and grouted into place by a groutdisplacement method. The bottom of the surface casing is fitted witha tight, drillable plug. The borehole is then filled with the estimatedvolume of cement-bentonite grout to fill the annular space, and the

casing is lowered to the bottom of the borehole (displacement

method). If the weight of the casing is not sufficient to displace thegrout and allow the casing to sink to the bottom of the borehole, thecasing may be filled with clean water.

After the surface casing installation, the grout will be allowed to setup for at least 12 hours before further drilling proceeds. The casingswill be pressure tested by filling the casing with clean water to withina short distance of the top and pressurizing the casing to

7 A R 3 0 I 0 2 9

approximately 20 psi (net pressure above ambient groundwater). Apressure drop of less than 1 psi in 5 minutes will prove an adequateseal.

B. Monitoring Well Installation

Prior to monitoring well installation in boreholes that have been drilled out

by mud rotary techniques, drilling fluid circulation will be continued until thedrill cuttings have been substantially removed from the borehole. Thedrilling fluid also will be thinned by the addition of clean water in order toallow the proper installation of sand pack and bentonite seal during wellconstruction.

The appropriate lengths of well screen, nominally 10 feet (with bottom cap),and casing will be joined watertight, and lowered to the bottom of the

borehole. Centering guides they will be placed at intervals around the well

casing, at the base of the screen, and 5 feet above the top of the well screen.

Selection of final filter pack and well screen depths for the wells shall bemade in the field.

A primary sand pack consisting of clean Morie No. 1 silica sand will beplaced around the well screen. The sand will be placed into the borehole ata uniform rate, in a manner that will allow even placement of the sand pack.

During placement of the sand, the position of the top of the sand will becontinuously sounded using a stainless steel weight attached to a fiberglass

tape measure. The primary sand pack will be extended from the bottom ofthe borehole to a minimum height of 2 feet above the top of the well screen.A secondary (fine) sand pack will then be installed to a minimum of 1 foot |

above the primary sand pack.

HR30I030

A bentonite pellet seal at least 2 feet thick will be placed above the sand

pack. The pellets will be placed into the borehole in a manner that willprevent bridging. The position of the top of the bentonite seal will be

verified using a weighted tape measure. A hydration period of at least 30minutes will be allowed following installation of the bentonite seal.

Above the bentonite seal, an annular seal of cement-bentonite grout will beplaced. The cement-bentonite grout will be installed continuously in one

operation from the bottom of the space to be grouted to the ground surfacethrough a tremie pipe. The tremie pipe must be plugged at the bottom andhave small openings along the sides of the bottom 1-foot length of pipe.

This will allow the grout to diffuse laterally into the borehole and not disturbthe bentonite pellet seal.

For monitoring wells that will be completed above-grade, the surface casing

itself will serve as the protective casing. The surface casing will be finished2 to 3 feet above grade and fitted with a locking steel cap. A concrete pad

with four guard posts will be installed.

The concrete pad will be square, approximately 3 feet per side, poured intowooden forms. The concrete will be sloped away from the protective casing.The concrete pad will extend at least 6 inches below and 6 inches above the

ground surface.

Four steel guard posts will be installed around the locking casing, within theedges of the concrete pad. Guard posts would be concrete-filled, at least 2inches in diameter, and would extend at least 2 feet into the ground and 3

feet above the ground. The protective casing and guard posts will be paintedwith an epoxy paint to prevent rust.

A R 3 0 I 0 3 !

For monitoring wells with flush-mount completions, a Morrison 519 manholecover with a rubber-sealed cover and drain will be installed. The top of themanhole will be positioned approximately 1 inch above grade. A squareconcrete pad, approximately 3 feet per side, will be installed as a concretecollar surrounding the road box cover, and will slope uniformly downward tothe adjacent grade. The road box and installation thereof will be of sufficientstrength to withstand normal vehicular traffic. The concrete pad will extendat least 12 inches below the ground surface.

Inside the manhole, a locking cap will be placed over the permanent casing.

Each well will be labeled on the exterior of the locking cap with a metalstamp indicating the permanent well number.

C. Well Development

Well development will be accomplished using the same techniques described Iin SOP 2.

SOP 4: Soil Sampling


The purpose of this procedure is to provide guidelines for obtaining samples ofsurface and subsurface soils using hand and drilling-rig mounted equipment.


• Stainless-steel trowel, shovel, scoopula, coring device, trier, handauger, or other appropriate hand tool

• Stainless-steel, split-spoon samplers

• Thin-walled samplers (e.g., Shelby tubes)

• Drilling rig or soil-coring rig

• Stainless-steel pan or bowl

• Scoopula or other appropriate hand tool

• Sample bottles

AR30 I031*

HI. PROCEDURES AND GUIDELINES

A. Surface Sampling

Before sampling begins, equipment will be decontaminated using the

procedures described in SOP 6: Decontamination of Drilling Rigs andEquipment. The sampling point is located and recorded in the field logbook.

Debris should be cleared from the sampling location.

A shovel, post-hole digger, or other tool can be used to remove soil to apoint just above the interval to be sampled. A decontaminated sampling toolwill be used to collect the sample when the desired sampling depth has beenreached. The sampling tool should be stainless steel and decontaminated inaccordance with the procedures outlined in SOP 6. Soil for semivolatileorganic and inorganic analyses is placed in the bowl and mixed; soil for

volatile organic analysis is not mixed or composited but is placed directlyinto the appropriate sample bottles. A stainless-steel or dedicated wooden

tongue depressor is used to transfer the sample from the bowl to the

container.

The soils removed from the borehole should be visually described in the fieldlog book, including approximated depths.

When sampling is completed, flame ionization device (FID) readings shouldbe taken directly above the hole, and the hole is then backfilled. Aftersampling the collected samples are labeled and handled as described inSOP 23.

A R 3 0 I 0 3 5

B. Split-Spoon Sampling

By use of a drilling rig at other soil boring locations, a hole is advanced to

the desired depth. For split-spoon sampling, the samples are then collectedfollowing the ASTM D 1586 standard (attached). The sampler is loweredinto the hole and driven to a depth equal to the total length of the sampler;

typically this is 24 inches. The sampler is driven in 6-inch increments usinga 140-pound weight ("hammer") dropped from a height of 30 inches. To

obtain enough volume of sample for subsequent laboratory analysis, use of a3-inch ID sampler may be required. Blow counts obtained with a 3-inch ID

spoon would not conform to ASTM D 1586 and would therefore not be used

for geotechnical evaluations. The number of hammer blows for each 6-inchinterval is counted and recorded.

Once retrieved from the hole, the sampler is carefully split open. Careshould be taken not to allow material in the sampler to fall out of the openend of the sampler. To collect the sample, the surface of the sample should

be removed with a clean tool and disposed of. Samples collected forvolatiles analysis should be placed directly into the sample containers fromthe desired depth in the split spoon. Material for collection of samples for allother parameters should be removed to a decontaminated stainless steel tray.The sample for non-volatiles analysis should be homogenized in the field by

breaking the sample into small pieces, and removing gravel. Thehomogenized sample should be placed in the sample containers. If samplevolume requirements are not met by a single sample collection, additionalsample may be collected by collecting a sample from below the sample, andcompositing the sample for non-volatile parameters only.

Split-spoon samples also will be collected using a tripod rig. When using atripod rig the soil samples are collected using an assembly similar to thatused with the drilling rigs.

A R 3 0 I 0 3 6

C. Shelby Tube Sampling

Thin-walled samplers are advanced hydraulically by continuous pressure froma drilling rig. ASTM D 1587 is the standard for this method. At the end ofthe designated push interval and before lifting the sample, the sampler istwisted to break the bottom of the sample.

Upon recovery of the sampler, the actual length of the sample is measured

and recorded, excluding slough or cuttings. At least 1/2-inch of soil iscleaned from each end of the sampler. The soil that has been cleaned fromthe sample can be used for visual classification.

Each end of the sampler is waxed. After the initial sealing, a filler (e.g.,

paper or sand) can be placed hi the remaining open area of the sampleravoid breaking of the initial end seals. The ends of the sampler areclosed with tight-fitting metal or plastic caps, and the seam between the cap

and sampler is taped. The ends of the sampler may be dipped in hot wax tocompletely cover the tape and seal the sampler. The sample and the top capare labeled with appropriate information, including the designation of theboring, the date and time of sampling, the sample number, and pertinentinformation about the collection of the sample. The side of the sampler is

marked as to which end is the top and which is the bottom. The samplershould be carried gently and kept in an upright, vertical position as much as

possible to maintain the in situ orientation and to minimize sampledisaggregation.

A R 3 0 I 0 3 9

Instructions for Completing Soil Boring Logs

Soil boring logs will be completed in the field log books. Information collected will be

consistent with that required for Form D1586, a standard CH2M HILL form.

The information collected in the field to perform the soil characterization is described

below.

Field personnel should review completed logs for accuracy, clarity, and thoroughness of

detail. Samples also should be checked to see that information is correctly recorded on

both jar lids and labels and on the log sheets.

Heading Information

Boring/Well Number. Enter the boring/well number. A numbering system should b\chosen that does not conflict with information recorded for previous exploratory work

done at the site. Number the sheets consecutively for each boring.

Location. If stationing, coordinates, mileposts, or similar project layout information is

available, indicate the position of the boring to that system using modifiers such as"approximate" or "estimated" as appropriate.

Elevation. Elevation will be determined at the conclusion of field activities.

Drilling Contractor. Enter the name of the drilling company and the city and state

where the company is based.

Drilling Method and Equipment. Identify the bit size and type, drilling fluid (if

used), and method of drilling (e.g., rotary, hollow-stem auger). Information on thedrilling equipment (e.g., CME 55, Mobile B61) also is noted.

A R 3 0 I O U O

Water Level and Date. Enter the depth below ground surface to the apparent waterlevel in the borehole. The information should be recorded as a comment. If free wateris not encountered during drilling or cannot be detected because of the drilling method,this information should be noted. Record date and time of day (for tides, river stage) ofeach water level measurement.

Date of Start and Finish. Enter the dates the boring was begun and completed. Timeof day should be added if several borings are performed on the same day.

Logger. Enter the first initial and full last name.

Technical Data

Depth Below Surface. Use a depth scale that is appropriate for the sample spacing andfor the complexity of subsurface conditions.

Sample Interval. Note the depth at the top and bottom of the sample interval.

Sample Type and Number. Enter the sample type and number. For instance, S-l =

split spoon, first sample. Number samples consecutively regardless of type. Enter asample number even if no material was recovered in the sampler.

Sample Recovery. Enter the length to the nearest 0.1 foot of soil sample recoveredfrom the sampler. Often, there will be some wash or caved material above the sample;do not include the wash material in the measurement.

Standard Penetration Test Results. In this column, enter the number of blowsrequired for each 6 inches of sampler penetration and the "N" value, which is the sum of

the blows in the middle two 6-inch penetration intervals. A typical standard penetrationtest involving successive blow counts of 2, 3, 4, and 5 is recorded as 2-3-4-5 and (7).

The standard penetration test is terminated if the sampler encounters refusal. Refusal isa penetration of less than 6 inches with a blow count of 50. A partial penetration of 50blows for 4 inches is recorded as 50/4 inches.

A'R30IOM

Sample may be collected using a 300-pound hammer or 3-inch-diameter split-spoon

samples at the site. Use of either of these sample collection devices invalidates standardpenetration test results and should be noted in the comments section of the log. The

300-pound hammer should only be used for collection of 3-inch-diameter split-spoonsamples. Blow counts should be recorded for collection of samples using either a 3-inch

split-spoon, or a 300-pound hammer. An "N" value need not be calculated.

Soil Description. The soil classification should follow the format described in the"Field Classification of Soil" subsection.

Comments. Include all pertinent observations (changes in drilling fluid color, rod

drops, drilling chatter, rod bounce as in driving on a cobble, damaged Shelby tubes, and

equipment malfunctions). In addition, note if casing was used, the sizes and depthsinstalled, and if drilling fluid was added or changed. You should instruct the driller toalert you to any significant changes in drilling (changes in material, occurrenceboulders, and loss of drilling fluid). Such information should be attributed to the drillerand recorded in this column.

Specific information might include the following:

• The date and the time drilling began and ended each day

• The depth and size of casing and the method of installation

• The date, time, and depth of water level measurements

• Depth of rod chatter

• Depth and percentage of drilling fluid loss

• Depth of hole caving or heaving

Field Classification of Soil

This section presents the format for the field classification of soil. In general, theapproach and format for classifying soils should conform to ASTM D 2488-90, Visual-Manual Procedure for Description and Identification of Soils.

The Unified Soil Classification System is based on numerical values of certain soilproperties that are measured by laboratory tests (ASTM D 2487). It is possible,

however, to estimate these values in the field with reasonable accuracy using visual-manual procedures (ASTM D 2488-90, attached). In addition, some elements of a

complete soil description, such as the presence of cobbles or boulders, changes in strata,and the relative proportions of soil types in a bedded deposit, can be obtained only in

the field.

Soil descriptions should be precise and comprehensive without being verbose. Thecorrect overall impression of the soil should not be distorted by excessive emphasis on

insignificant details. In general, similarities rather than differences between consecutivesamples should be stressed.

Soil descriptions must be recorded for every soil sample collected. The format andorder for soil descriptions should be as follows:

1. Soil name (synonymous with ASTM D 2488-90 Group Name) with appropriatemodifiers

2. Group symbol

3. Color

4. Moisture content

5. Relative density or consistency

6. Soil structure, mineralogy, or other descriptors

This order follows, in general, the format described in ASTM D 2488-90.

Soil Name

The basic name of a soil should be the ASTM D 2488-90 Group Name on the basis ofvisual estimates of gradation and plasticity. The soil name should be capitalized.

Examples of acceptable soil names are illustrated by the following descriptions:

• A soil sample is visually estimated to contain 15 percent gravel,55 percent sand, and 30 percent fines (passing No. 200 sieve). The fines

are estimated as either low or highly plastic silt. This visual

classification is SILTY SAND WITH GRAVEL, with a Group Symbolof (SM).

• Another soil sample has the following visual estimate: 10 percentgravel, 30 percent sand, and 60 percent fines (passing the No. 200 sieve).

The fines are estimated as low plastic silt. This visual classification isSANDY SILT. The gravel portion is not included in the soil name

because the gravel portion was estimated as less than 15 percent. TheGroup Symbol is (ML).

The gradation of coarse-grained soil (more than 50 percent retained on No. 200 sieve) isincluded in the specific soil name in accordance with ASTM D 2488-90. There is nneed to further document the gradation. However, the maximum size and angularity or

roundedness of gravel and sand-sized particles should be recorded. For fine-grained soil

6 A R 3 0 I 0 5 0

(50 percept or more passing the No. 200 sieve), the name is modified by the appropriateplasticity/elasticity term in accordance with ASTM D 2488-90.

Interlayered soil should each be described starring with the predominant type. Anintroductory name, such as "Interlayered Sand and Silt," should be used. In addition,the relative proportion of each soil type should be indicated (see Table 1 for example).

Where helpful, the evaluation of plasticity/elasticity can be justified by describing resultsfrom any of the visual-manual procedures for identifying fine-grained soils, such as

reaction to shaking, toughness of a soil thread, or dry strength as described in ASTM D2488-90.

Group Symbol

The appropriate group symbol from ASTM D 2488-90 must be given after each soil

name. The group symbol should be placed in parentheses to indicate that theclassification has been estimated.

In accordance with ASTM D 2488-90, dual symbols (e.g., GP-GM or SW-SC) can beused to indicate that a soil is estimated to have about 10 percent fines. Borderlinesymbols (e.g., GM/SM or SW/SP) can. be used to indicate that a soil sample has been

identified as having properties that do not distinctly place the soil into a specific group.Generally, the group name assigned to a soil with a borderline symbol should be thegroup name for the first symbol. The use of a borderline symbol should not be usedindiscriminately. Every effort should be made to first place the soil into a single group.Grain size is estimated in accordance with ASTM D 2488-90 (Table 2).

Color

The color of a soil must be given. The color description should be based on the

Munsell system. The color name and the hue, value, and chroma should be given.

A R 3 0 I 0 5 I

Moisture Content*

The degree of moisture present in a soil sample should be defined as dry, moist, or wet.Moisture content can be estimated from the criteria listed on Table 3.

Relative Density or Consistency

Relative density of a coarse-grained (cohesionless) soil is based on N-values (ASTM D1586-84, attached to SOP 4). If the presence of large gravel, disturbance of the sample,or non-standard sample collection makes determination of the in situ relative density or

consistency difficult, then this item should be left out of the description and explained inthe Comments column of the soil boring log.

Consistency of fine-grained (cohesive) soil is properly based on results of pocketpenetrometer or torvane results. In the absence of this information, consistency canestimated from N-values. Relationships for determining relative density or consistencyof soil samples are given in Tables 4 and 5.

Soil Structure, Mineralogy, and Other Descriptors

Discontinuities and inclusions are- important and should be described. Such featuresinclude joints or fissures, slickensides, bedding or laminations, veins, root holes, andwood debris;

Significant mineralogical information such as cementation, abundant mica, or unusualmineralogy should be described.

Other descriptors may include particle size range or percentages, particle angularity orshape, maximum particle size, hardness of large particles, plasticity of fines, drystrength, dilatancy, toughness, reaction to HC1, and staining, as well as other informationsuch as organic debris, odor, or presence of free product.

A R 3 0 I 0 5 2

Equipment and Calibration

Before starting the testing, the equipment should be inspected for compliance with the

requirements of ASTM D 1586-84. The split-barrel sampler should measure 2-inch or3-inch O.D., and should have a split tube at least 18 inches long. The minimum size

sampler rod allowed is "A" rod (1-5/8-inch O.D.). A stiffer rod, such as "N" rod(2-5/8-inch O.D.), is required for depths greater than 50 feet. The drive weight

assembly should consist of a 140-pound or 300-pound hammer weight, a drive head, anda hammer guide that permits a free fall of 30 inches.

A. Methodology

Empty, clean drums will be brought to the site by the drilling subcontractorfor soil and groundwater collection and storage. The empty drums will belocated at the field staging area and moved to drilling locations as required.The drums will be filled with the drilling and well installation wastes,capped, sealed, and moved to the onsite drum storage area by the drillingsubcontractor. The full drums will separate types of wastes by media. Thedrums will be labeled as they are filled in the field and labels indicating thatthe contents are potentially hazardous affixed. Soils registering less than 10

ppm with the OVA in a headspace screening will not be drummed, but willbe spread at the boring location and left.

The contents of the drums will be sampled to determine the disposalrequirements of the drilling wastes. The drum sampling will beaccomplished through the collection and submittal of composite samples as aseries of 10 drums containing the same media. The compositing of thesample will be accomplished through the collection of a specific volume ofthe material in each drum into a large sample container. When samples fromeach of the drums being sampled in a single compositing are collected, thesample will be submitted for TCLP analysis through the CLP. The TCLPanalysis will be used to determine if drilling wastes are covered by landdisposal restrictions.

AR30 I056

The test was started by rapidly removing the displacement device, which causes adrop in the water level. The data logger begins recording the water level and

elapsed time when the preset trigger amount is reached. Readings are taken asabove, and the test stopped when the well has recovered to 90 percent of the originallevel.

At the end of each day, the test results will be transferred to a computer disk. The

computer will be attached to the data logger and the data downloaded and checkedfor preliminary completeness.

When development and purging is completed, the water will be tested forappropriate hazardous waste constituents. A portion sample will be obtainedfrom each drum. A composite sample from 10 drums will be submitted tothe CLP for analysis for disposal parameters.

D. Solids

Most of the volume of solids to be disposed of is made up of soil cuttingsfrom well and boring drilling.

Solids also will include plastic sheeting used for decontamination pads,tyveks, disposable sampling materials, and any other disposable material used

during the field operations that appears to be contaminated. These materialswill be placed in designated drums.

E. Storage and Disposal

The wastes generated at the site at individual locations will be transported tothe fenced drum storage area by the drilling services subcontractor.

Waste solid materials that contain hazardous constituents will be disposed ofat an offsite location in a manner consistent with applicable solid waste,hazardous waste, and water quality regulations. Transport and disposal willbe performed by a commercial firm under subcontract.

The liquid wastes meeting acceptable levels of discharge contamination willbe disposed of through the sanitary sewer system at the site.

in Section III text.

• Open tube sampler• Dip sampler

• Weighted bottle sampler

• Hand pump• Kemmerer or Van Dorn sampler• Depth-integrating sampler• Sample containers

• Meters for specific conductance, temperature, pH, and dissolved oxygen

in. PROCEDURES AND GUIDELINES

Before surface water samples are taken, all sampler assemblies and sample containers

are cleaned and decontaminated as described hi SOP 6. All sample bottles arelabeled and handled in accordance with SOP 23. Method for taking surface watersamples are described below.

A R 3 0 I 0 6 I

A. Manual Sampling

Surface water samples are taken manually by submerging a clean glass,stainless steel, or Teflon container into the water body. Samples may betaken at depth with a covered bottle that can be removed with a tripline. The

most common sampler types are beakers, scalable bottles and jars, pondsamplers, and weighted bottle samplers. Pond samplers have a fixed or

telescoping pole attached to the sample container. Weighted bottle samplersare lowered below water surface, where the attached bottle is opened,

allowed to fill, and pulled out of the water. When retrieved, the bottle istightly capped and removed from the sampler assembly. Specific types ofweighted bottle samplers include dissolved oxygen, Kemmerer, or Van Dorn,

and are acceptable in most instances.

A sample is taken with the following specific steps:

1 . The location and desired depth for water sampling are selected.

2. The sample site is approached from downstream in a manner that

avoids disturbance of bottom sediments as much as possible. Thesample bottle is gently submerged to just below the water surfacewith the mouth pointed upstream and the bottle tilted slightly

downstream. Bubbles and floating materials should be preventedfrom entering the bottle.

3. For weighted bottle samplers, the assembly is slowly lowered to thedesired depth. The bottle stopper is unseated with a sharp tug and the

bottle is allowed to fill until bubbles stop rising to the surface.

4. When the bottle is full, it is gently removed from the water. Ifsample transfer is required, it should be performed at this time.

2 A R 3 0 I 0 6 2

B. Mechanical Sampling

Mechanical surface water sampling involves a peristaltic pump that conveyswater through heavy-walled tubing to a container. The tubing must be

flexible and made of a non-reactive material such as Tygon or Teflon; Teflonis usually selected when oil and grease are present. Medical-grade or silicon

tubing may be satisfactory in some cases, depending on the constituents to beanalyzed. An external power source may be required, but many peristalticpumps are equipped with batteries.

In some situations, it may be desirable or necessary to locate the container

between the water intake and the pump connection. The peristaltic pumpmay then be used as a vacuum pump. The vacuum pump method cannot be

used for samples on which analyses for volatile organic compounds (VOCs)will be conducted, as it very effectively strips VOCs from water.

When sampling at depths or in fast currents, the inlet tubing is weighted or

attached to some stationary object such as a bridge piling or a pole stuck hibottom sediments. Weighting the tubing can cause stretching and reduce theinside tubing diameter, which reduces pump capacity. Insertion of a pole

into bottom sediments adds particulates to the water column. Water sampling

should not commence until particulates have settled.

The following steps are taken hi mechanical surface water sampling:

1. The inlet and outlet tubing is connected to the appropriate portslocated on the pump housing. The interior of the housing is checkedto be sure that the pump tubing is properly connected.

2. The intake end of the inlet tubing is placed at the selected samplelocation, and the discharge end of the outlet tubing is placed in the

A R 3 0 I 0 6 3

sample container. The sample is pumped until the sample container isfull. The pump may be allowed to run for a period of time to flushthe sampling device before collecting a sample.

3. When the pump is stopped, the discharge end of the outlet tube isremoved from the sample container. The sample container is cappedand labeled.

4. If the peristaltic pump is being used as a vacuum pump, the inlet

tubing at the top of the collection container is detached first. Thisprevents back-siphoning when the vacuum is released. The vacuum isreleased by slowly admitting air as the inlet tubing is disconnected toprevent blow-back and reduce aeration of the sample. After thevacuum is released, the sample is transferred to a sample bottle.

5. Peristaltic pumps are cleaned and decontaminated by disposing of theinterior and exterior tubing. Tubing is difficult to completely clean,particularly of oils and greases.

m. PROCEDURES AND GUIDELINES

A. Calibration

Calibrate unit prior to initial daily use. There are no calibration proceduresfor the redox electrode. Calibrate with at least two solutions. Clean theprobe according to the manufacturer's recommendations. Duplicate samplesshould be run once every 10 samples. The order of calibration solutions willbe based on the instrument manufacturer's recommendation.

1. Place electrode in pH 7 buffer solution.

2. Allow meter to stabilize, and then turn calibration dial until a readingof 7.0 is obtained.

3. Rinse electrode with deionized water and place it in a pH 4 or pH 10buffer solution.

4. Allow meter to stabilize again and then turn slope adjustment dialuntil a reading of 4.0 is obtained for the pH 4 buffer solution or 10.0for the pH 10 buffer solution.

5. Rinse electrode with deionized water and place in pH 7 buffer. Ifmeter reading is not 7.0, repeat sequence.

B. Procedure

1. Before going out into the field:

a. Check batteries.b. Do a quick calibration at pH 7 and 4 to check electrode.

A R 3 0 I Q 7 0

c. Obtain fresh calibration solutions,d. Fill electrodes.

2. Calibrate meter using calibration procedure.

3. Pour the sample into a clean beaker.

4. Rinse electrode with deionized water between samples.

5. Immerse electrode in solution. Make sure the white KC1 junction on

the side of the electrode is in the solution. The level of electrodesolution should be one inch above sample to be measured.

6. Recheck calibration with pH 7 buffer solution after every fivesamples.

C. General

• 1. When calibrating the meter, use pH buffers 4 and 7 for samples with

pH <8, and buffers 7 and 10 for samples with pH >8. If meter willnot read pH 4 or 10, something may be wrong with the electrode.

•2. Measurement of pH is temperature dependent. Therefore, bufferstemperatures should be within about 2 degrees C of sample

temperatures. For refrigerated or cool samples, use refrigeratedbuffers to calibrate the pH meter.

3. Weak organic and inorganic salts and oil and grease interfere with pHmeasurements. If oil and grease are visible, note it on the data sheet.Clean electrode with soap and water and rinse with distilled water.Then recalibrate meter.

3 A R 3 0 I 0 7 I

4. Following field measurements, report problems and compare withprevious data. Clean dirt off meter and inside case and storeelectrode in pH 4 buffer.

5. Accuracy and precision are dependent on the instrument used; refer tomanufacturer's manual. Expected accuracy and precision are +/- 0.1pH unit.

6. The redox electrode should be checked prior to beginning site workand when anomalous readings suggest that the probe ismalfunctioning. The procedure for checking the redox electrode is asbelow:

a. Prepare solution A (0.1 M potassium ferrocyanide0.005 M potassium ferricyanide): weigh out 4.22 g

grade K4Fe(CN)6«3H2O and 1.65 g reagent-grade K3Fe(CN)6.Place in a 100 ml volumetric flask. Add about 50 ml distilledwater and swirl to dissolve solids. Dilute to volume withdistilled water.

b. Prepare solution B (0.01 M potassium ferrocyanide, 0.05 Mpotassium ferricyanide, and 0.36 M potassium fluoride):weigh out 0.42 g reagent-grade K4Fe(CN)6»3H2O 1.65 greagent-grade K3Fe(CN)6, and 3.39 g reagent-grade KF»2H2O.Place in a 100 ml volumetric flask. Add 50 ml distilled water,

and swirl to dissolve solids. Dilute to volume with distilledwater.

c. Transfer solution A to a 150 ml beaker. Place electrode insolution and wait until the reading stabilizes. The potential

should be about 234 mV.

SOP 21: Groundwater Sampling


This procedure presents guidelines for the collection of groundwater samples frommonitoring wells.


• Bladder-type groundwater sampling pump; QED Well Wizard or equivalent

• Pump controller and power supply (if electrical)

• Air supply; internal or external compressor or bottled air

• Probe box; stainless steel box with inlet/outlet ports for purged groundwaterand watertight ports for each probe

• pH/Eh meter; Orion Model SA250 or equivalent

• Dissolved oxygen meter

• Temperature/conductivity meter; YSI Model 33 or equivalent

• In-line disposable 0.45p, filters; QED FF8100 or equivalent

• Bailer, stainless steel

A R - 3 0 1 109

• Peristaltic Pump with Tubing (capable of yielding 2 gpm)

• Purge Pump


A. Setup and Purging

1. For the well to be sampled, information is obtained on well location,

diameter(s), depth, and screened interval(s), and the method fordisposal of purged water.

2. A pump will be used for well purging. The expected mechanisms isa surface pump with dedicated purge pipe for each well. Tjte

•N. bladder-type pumps will be used when contaminant distributBnpatterns suggest low levels of contamination.

3. Instruments are calibrated according to manufacturer's instructions.

4. The well number, site, date, and condition are recorded in the fieldlogbook.

5. Plastic sheeting is placed on the ground, and the well is unlocked andopened.

6. Water level measurements are collected in accordance with SOP 14,and the total depth of the well is measured.

A R 3 0 I I 1 0

7. The volume in gallons of water in the well casing or sections of

telescoping well casing is calculated as follows:

0.052 (n A) = 0.163 (A) = gallons

where: n = 3.14

r = Radius of the well pipe in inchesh = height of water in well in feet •

The volume of water in typical well casings may be calculated as

follows:

2-inch diameter well:

0.163 gal/ft x __ (linear feet of water ) = gallons

4-inch diameter well:0.653 gal/ft x __ (linear feet of water ) = gallons

6-inch diameter well:1.469 gal/ft x __ (linear feet of water ) = gallons

The initial field parameters of pH, Eh, dissolved oxygen, specific

conductance, and temperature of water are measured and recorded inthe field logbook. The measurement probes are inserted into theprobe box. The purged groundwater is directed throughout the box,

allowing measurements to be collected before the water contacts theatmosphere.

8. Sampling equipment is cleaned and decontaminated prior to samplingin accordance with SOP 6.

A R 3 Q I I i

9. If a bailer is being used, it is removed from either its protective

covering or the well casing and attached to a cord compatible withconstituents and long enough to reach the bottom of the well. If a

bladder pump is being used, air, sample, and lifting lines are attachedto the pump. The lifting lines should bear the weight of the pump;

the air and ? le lines are attached to the lifting lines at 10-footintervals. If the well is purged using dedicated tubing, it is loweredinto the well to the top of the screened zone.

10. The sampling device is lowered to the well interval from which the

sample is to be collected. If a bailer is being used, it is allowed tofill with a minimum of surface disturbance to prevent sample water

aeration. When the bailer is raised, the bailer cord must not touch theground.

For the bladder pump, the air lines from a regulated compressed gassource are connected to a control box, a power supply connected tothe pump, and air flow started and adjusted with the throttle knob on

the control box. Discharge and refill knobs on the control box areused to control the cycling rate of flow in the bladder. Equal lengthcycles are generally desirable, but individual well conditions should

be controlling.

11. During purging, the field parameters are measured at least onceduring each well volume.

In productive wells, the well purging end point is determined usingthe field measurements. In nonproductive wells, the well is

repeatedly bailed dry to obtain a minimum of three well volumes, Iallowed to recover before sampling.

A R 3 0 ! I 12

12. Three to five well volumes are purged (more may be purged if

parameters do not stabilize). Purging is stopped when fieldparameters have stabilized over two consecutive well volumes. Field

parameters are considered stabilized when pH measurements agreewithin 0.5 units, temperature measurements agree within 1°C, andspecific conductance measurements agree within 10 percent (e.g., 100

units for readings of 1,000 /^mhos/cm.

B. Sample Collection

Once purging has been completed, the well is ready to be sampled. The

elapsed time between completion of purging and collection of thegroundwater sample from the well should be minimized. Typically, the

sample is collected immediately after the well has been purged, but this isalso dependent on well recovery.

Samples will be placed in bottles that are appropriate to the respective

analysis and that have been cleaned to laboratory standards. Each bottletypically will have been previously prepared with the appropriatepreservative, if any.

The following information, at a minimum, will be recorded in the log book:

• Sample identification (site name, location, and project number;sample name/number and location; sample type and matrix;

time and date; sampler's identity)

• Sample source and source description

• Field observations and measurements (appearance, volatilescreening, field chemistry, sampling method), volume of water

A R 3 0 I I 13

purged prior to sampling, number of well volumes purged, and

field parameter measurements

• Sample disposition (preservatives added; laboratory sent to,

date and time sent; laboratory sample number, EPA TrafficReport or Special Analytical Services number, chain-of-

custody number, sample bottle lot number)

• Additional remarks

The steps to be followed for sample collection are as follows:

1. The cap is removed from the sample bottle, and the bottle is tiltedslightly.

2. The sample is slowly poured from the bailer or discharged from the

pump so that it runs down the inside of the sample bottle with aminimum of splashing. Samples may be field filtered before transfer

to the sample bottle. Filtration must occur in the field immediatelyi

upon collection. Inorganics, including metals, are to be collected andpreserved in the filtered form. The recommended method is through

the use of a disposable in-line filtration module (0.45 micron filter)using the pressure provided by the pumping device for its operation.

When a bailer is used, filtration may be driven by a peristaltic pump.

3. Samples collected for VOC analysis will be collected using a bailerwhen the well is purged using dedicated tubing and a surface pump.

4. Adequate space is left in the bottle to allow for expansion, excepiBirVOC vials, which are filled to overflowing and capped.

6 A R 3 0 I I U

5. The bottle is capped, then labeled clearly and carefully, in accordancewith Procedure No. 23.

6. Samples are placed in appropriate containers and, if necessary, packedwith ice in coolers as soon as practical.

7. If the sampler is dedicated, it is returned to the well and the well is

capped and locked. Nondedicated samplers are cleaned anddecontaminated in accordance with Procedure No. 6.

IV. ATTACHMENTS

None.


Maintain field equipment in accordance with the manufacturer's recommendations;this will include, but is not limited to:

• Inspect pump bladder regularly and replace as warranted

• Inspect tubing regularly and replace as warranted

• Inspect air/sample line quick-connects regularly and replace as warranted

• Verify battery charge, calibration, and proper working order of field

measurement equipment prior to initial mobilization and daily during field

efforts

SOP 22: Aquifer Testing


The purpose of this procedure is to outline the equipment and methods that will beused to perform variable-head tests ("slug" tests) on the new monitoring wells.


Campbell Scientific, Inc., Model 2IX dataloggerDruck pressure transducers

Well testing assembly ("beast")packerfittings for pressure transducersfittings for air supplyrelease valve

Compressed airComputer and associated equipmentSolid displacement device with rope

lU. PROCEDURES AND GUIDELINES

The tests which will be preformed are rising head tests. The tests are accomplished

by lowering the head of water in the well, and monitoring the recovery of the waterlevel to the static water level. The water level will be lowered by one of two

methods. In most cases, an air displacement device will be used. An alternatemethod is the use of a solid displacement device removed from the well.

A R 3 0 I I 16

The air displacement apparatus consists, of a packer assembly, fittings to

accommodate transducers and air pressurization, and a pressure-release valve. Thepacker is lowered into the ur::er portion of the monitoring well, secured in place andinflated, providing a seal between the apparatus and the inside of the well. Two

fittings are provided for pressure transducers; one transducer is fed through theinside of the device and positioned below the water surface, and the other is inserted

to measure the air pressure inside the assembly. A third fitting is connected to thepressurized air supply, a compressed air tank.

The datalogger will be programmed to display the air pressure in units of head, thehead measured by the submerged transducer, and the difference between the two.

The difference between the two pressure transducers is the height of the watercolumn on the submerged transducer. These readings are recorded hi a field

notebook, and then the assembly is pressurized. The air pressure applied willêquivalent to 3 to 7 feet of head. The pressures are allowed to stabilize,

pressure of the air should not lower the water level to below the base of thebentonite seal installed in the well.

11J*

TTC

Each test is started by releasing the air pressure inside the assembly and allowing thewater level to rise to the static water level. When the datalogger perceives a change

in water level in the well above a preset trigger amount, it automatically begins to

record the water levels and elapsed time. Each test will be terminated when thewater level has recovered to at least 90 percent of the original equilibrium levelbefore pressurization.

At some wells, it may be necessary to use an alternate method of lowering the water

level because the well is screened across or near the water table. A single transducerwill be installed in the well below the water table. A weighted solid displacement

device is added to the well and the water level allowed to stabilize at the ostatic water level.

SOP 23: Region III Sample Paperwork

A.R30I I 18

EPA Sample Paperwork November 2, 1992

The following pages contain information that was designed to assist you in completing theEPA Sample Paperwork correctly. In order for these checklists to be effective you needtraining on how to fill out the paperwork by the sample manager. Without the training,these checklists will not be as effective.

The intent of these checklists is to make you think about what you are doing. It isextremely easy to make a simple error, and following the checklists will help eliminatethose errors.

You will notice as you read through the beginning pages that we talk about a lot of pre-sampling preparation of the paperwork: we strongly recommend you do this. It makes thesampling event go much smoother and you are not so pressed for time at the end of the day.

During the sampling event there are a few things you should keep in mind:

• Always follow the Sampling and Analysis Plan (SAP). The SAP is the Biblefor all sampling events and its procedures should be followed as they aredescribed.

• QC samples: make sure all of the QC requirements listed in the SAP arecovered.

• Never call SMO with any questions at all. We are not allowed to talk tothem unless we are giving them shipping information.

• Send copies of the completed paperwork to the Sample Manager (DavidClark/WDC) every night you ship samples (by Federal Express or FAX).CRL and SMO often have questions and we need to be able to look at thepaperwork to answer these questions.

• PLEASE CALL IN THE EVENT YOU ARE UNSURE ABOUTANYTHING!! WE ARE HERE TO HELP.• Sample Manager - David Clark/WDC (x4305)• Site Manager - Site Specific• Secondary Sample Manager - Koumudi Ketkar/WDC (x4238)

A R 3 0 I I 1 9

Sample Preparation Checklist

__ If the sampling event has SAS analyses, have you had the SAS request written and summeda minimum of 6 weeks before the sampling takes place?

Check the following 1 week before sampling:

Things to complete: __ Has the RAS lab been set up yet? (if applicable, callsample manager the Monday of the week before samplingto have the lab set up. Include total number of samples aswell as the QC requirements).

__ Review the Sampling and Analysis Plan (SAP).__ Where is the closest Federal Express office?

Do you have enough: __ Coolers (remember that organics and inorganics often goto different labs).

__ Bottles (see enclosed list to get proper bottles for desiredanalyses)

__ Preservative (see enclosed list to get proper preservativefor desired analyses)

__ Paperwork (tags, chain of custody forms, etc. - Call theSample Manager - David Clark - to get these forms ifneeded)

__ Water-proof pens__ Filters? If you have a Metals analysis will

filtering these samples?__ HPLC water__ Federal Express Forms__ Sample Equipment (pumps, meters, H&S, etc.)__ Trip blanks for VOA analysis? (if applicable)

Before going out into the field, it is a good idea to fill out the paperwork as much as possible,especially if you will be doing oversite (OS.) work at the same time. Putting everything onto oneform and then copying it over to new forms as those samples are collected and shipped out to the labshas been found to be extremely helpful, especially for people who are new to EPA paperwork, orhave been away from it for a while.

If you begin to fill out the paperwork ahead of time, and you feel at all uncomfortable, please ask fora refresher training session. It doesn't take that long, and it will be a great help to you, so please takeadvantage of it. Even people who have done this before need to be refreshed from time to time. It iseasy to make a simple mistake, so if you are unsure of what is supposed to be done, please ask forhelp.

The easiest way we have found to fill out the paperwork before the sampling event is by placing thecorresponding tags and sticky labels in envelopes by location identifier. This will allow you to justgrab the envelope for the specific location being sampled at that time. You can fill in just abouteverything on the paperwork. On the enclosed checklists for each form of paperwork, itcan and can't be filled out in advance. This is a huge time saver if all is filled out andyou go into the field. When filling out the paperwork ahead of time, make sure you also write up theinformation for all QC samples (MS/MSD, Field Blanks, Trip Blanks, etc.). The sample manager canassist you on preparing the paperwork ahead of time to make sure you are comfortable with thisprocedure for future sample activities.

Frequent Paperwork ProblemsThings To Avoid Doing

• Dissolved Metals analysis didn't get a separate CLP sample number from that of theTotal Metals.

Whenever you take a total and dissolved metals sample, they MUST get separate CLPSample Numbers. If they don't you will be writing a memo-to-file soon there after.

• Sampler didn't call SMO with shipping information or didn't call SMO before 3:00pmon Friday for Saturday deliveries.

Every night samples are shipped we need to call SMO with the shipping information.SMO needs to know about Saturday deliveries before 3:00pm so they can make suresomeone is at the lab to receive the samples.

• Tags incorrectly noted on the Chain of Custody form.

You need to be very careful when writing down these numbers. It is easy to transposenumbers or place them in the wrong box. This is a much to common problem thatneeds to be reversed, and that will be done only by being careful.

• MS/MSD samples not given the same CLP sample number.

When ever you collect a sample and an MS/MSD, all volumes need to get the sameCLP sample number. Example: You collect the sample, the MS and the MSD, this istriple the volume of normal. You will assign the same CLP sample number to all 3sets of samples. The reason, they are not separate samples, they are one in the samefor the lab to be able to perform QC on them.

• Sample description for trip blanks and field blanks not noted as LEACHATES,equipment blanks not noted as RINSATES.

EPA protocol calls for us to assign the description (Box 7 for the Organic andInorganic paperwork, Box 6 for the SAS paperwork) for the Trip Blanks and FieldBlanks as Leachates, while Equipment Blanks are called Rinsates.

Sample Paperwork Checklist - Miscellaneous

__ If the shipment of samples is delayed or canceled, call the sampleDavid Clark/WDC at 703/471-6405 (ext. 4305). Please give a reason for thedelay/cancellation. CRL always needs a reason for delays/cancellations.

__ Did you double check SAS/RAS Numbers on the tags, labels and forms?__ Did you write out complete sample numbers on each tag? Did you use

preprinted sticky labels?__ Did you assign the same CLP Sample No. to all volumes of any MS/MSDs?__ Did you check tags, bottles, and forms for matching times and dates of sample

collection?__ Did you neatly cross-out any changes with one line, initial and date the change?

WRITE-OUT IS PROHIBITED!__ Did you put the airbill number on the chain of custody forms?__ Are the lab copies of the forms, the last 2 sheets of the paperwork, protected in

. the cooler, taped to the cooler lid? The sample shipping log does not go in thecooler.

__ Is the ice packed in plastic bags to minimize leakage during shipping?__ Are the tags securely attached to each sample bottle?__ Is each container sealed in a plastic bag (when appropriate)?__ Did you sign the "Relinquished by" box and fill in the date and time boxes?__ Are the chain-of-custody seals taped on cooler and secured with clear tape over

them to prevent accidental breakage of the seals?__ Is the CH2M HILL return address written on the front outside corner

cooler? If not, write it on there so the cooler will make its way back toHILL.

__ Did you write "Attention-Sample Custodian" on the Lab Address?__ Are all samples being shipped PRIORITY OVERNIGHT? - No GSA airbills,

use CH2M HILL airbills (bulk volume discount). Reason, GSA not guaranteedto get there in the AM the following day.

__ If Saturday delivery is required, the Federal Express form MUST be checkedfor Saturday delivery.

* Do not call labs or send them the sample shipping log__ Call EPA Sample Management Office (SMO) with complete sample

information. Many times you will reach an answering machine, you may leavethe complete shipping information in a message. This is the only thing we talkto SMO about. All other questions should go to the sample manager, DavidClark/WDC:

SAS Samples: Heather Kaese 703/519-1413RAS Samples: Jane von Hofen 703/519-1353

Sample Paperwork Checklist - Memo-to-File

In the event you have made a mistake and you are told you need to do a memo-to-file or youdiscovered an error that requires a memo-to-file, there are some requirements as to the content ofmemo. This memo needs to be written and submitted IMMEDIATELY. The following is a list ofthose items that are required to be in that memo so they will be able to easily identify that sampleactivity:

__ Case(RAS)/SAS Number__ Overnight Carrier/Airbill Number__ Date of Shipment__ Chain-of-Custody Document Number__ Sample Numbers__ Tag Numbers__ Sampling Dates__ Analysis__ Correction of the Error__ Your Signature

* DON'T PUT THE SITE NAME IN THE MEMO-TO-FILE UNLESS THELAB WAS CRL.

Once all this is included in the memo-to-file it needs to be distributed to certain individuals:

5. Select fish (target species) of the size that would be retained by fishermenwill be retained for tissue analysis. Target species of interest will be speciessuch as White Sucker or Carp. These species feed on invertebratesassociated with the bottom material, would most likely uptake contaminantsof concern, and could be utilized as a food resource by higher vertebrates,including man. Where possible, those specimens that are about the samesize (length and weight) will be retained.

6. Select fish (target species) will be retained for whole fish analysis. Thetarget species will be those that are bottom feeders which would most likelyuptake contaminants of concern, and could be used as a food resource byhigher vertebrates.

7. Sampling equipment, including the fish measuring board, will bedecontaminated according to the procedures outlined in SOP 6 betweensamples.

8. Information on habitat condition of the lagoon will be recorded, includingwater depth, substrate type, shoreline profile or vegetation and degree ofshading.

SOP 25: FISH SAMPLE COLLECTION PROCEDURES


To provide general guidelines on collecting, preserving, and shipping fish samplesfor chemical analysis. Fish samples will be collected using an electroshocker.Selected fish will be analyzed as whole fish or edible tissues for parameters ofinterest at the site.


• Sample containers: teflon baggies, sample jars, aluminum foil

• Stainless steel knife

• Stainless steel tray, fillet board

• Personal protective equipment

• Coolers

• Dry ice

• Buckets

ffl. PROCEDURES AND GUIDELINES

After being collected, fish will be placed hi a live-well or equivalent until they canbe processed. Processing of fish includes identification, measuring weight andlength, and determining if they will be retained for analysis. Fish retained foranalysis will be killed by suffocation.

Fish will be collected for both whole fish and selected tissue analysis. Fish selectedfor selected^tissue analysis will be evaluated using Attachment 1 to determine if theskin should be removed. The fish will be filleted according to the procedureoutlined hi Attachment 2. Wastes generated during filleting will be disposed of aspotentially hazardous materials. Between each fillet, the sample handling equipmentwill be decontaminated according to SOP 6.

Samples for organics will be wrapped hi aluminum foil with the shiny side out.The aluminum foil will be taped shut using masking tape. The samples forinorganic analysis will be sealed in a teflon baggie. All of the samples will bestored and shipped to the analytical laboratories on dry ice.

1.1 SITE DESCRIPTION

The Halby Chemical site encompasses approximately 14 acres in Wilmington, New Castle County,Delaware. The site is hi an industrialized area near the Port of Wilmington and borders Terminal Avenueon the south, Interstate 495 on the northwest, and by a Conrail railroad track on the northeast. Thelocation of the Halby Chemical site is shown hi Figure 1.

1.2 SITE HISTORY AND CHRONOLOGY OF PREVIOUS ACTIONS

Halby Chemical Company, followed by Witco Chemical Company, produced sulfur compounds at the sitefrom 1948 to 1977. In 1977, Brandywine Chemical Company bought the site from Witco to use as astorage area for bulk chemicals for their distributorship. The site remains in operation as of October 1992.

• From 1948 to 1977, the Halby Chemical Company produced ammonium thioglycolate,ammonium thiocyanate, isooctyl thioglycolate, and other sulfur compounds on the site.

From 1948 to 1964, Halby Chemical used an onsite unlined lagoon for disposing ofliquid wastes, including cooling water; acid wastewater, and surface-water runoff fromthe process plant. During this period, the lagoon extended across the northwest quadrantof the site and north of the present site boundaries. In the early 1960s, a pit wasconstructed and was filled with limestone to treat the acidity of the wastewater prior todischarge to the lagoon. Between June 1962 and May 1968, route Interstate 495 (1-495)was constructed. The construction of the highway divided the lagoon, isolating thenorthern part of the lagoon from the Halby Chemical site.

From 1964 to 1972, acid wastewater was discharged into the public sewer system. ThepH, total suspended solids (TSS), biochemical oxygen demand (BOD), and chemicaloxygen demand (COD) of the water leaving the lagoon were regulated under a NationalPollutant Discharge Elimination System (NPDES) permit that expired on July 30, 1979.

In 1972, Argus Chemical Company, a wholly owned subsidiary of Witco Corporation,merged with Halby Chemical. They developed a pilot plant for wastewater treatment.The pilot plant was not operated on a regular basis; when it was operating, the treatedwastewater was discharged to the lagoon.

In 1977, Brandywine Chemical Company bought the property for use as a storage areafor bulk chemicals for their distributorship.

In December 1983, Delaware Department of Natural Resources and EnvironmentalControl (DNREC), working under Emergency and Remedial Response InformationSystem (ERRIS), completed a preliminary action (PA) of the Halby Chemical site(AEPCO, 1990). The PA was followed in March 1984 by a site investigation (SI) con-ducted by an EPA Field Investigation Team (FIT) III. Samples analyzed for the SIcontained high levels of a wide variety of organic and inorganic compounds in variousmedia, including groundwater and sediment samples. The report was published onJanuary 10, 1986.

During the 1984 site inspection, a crushed and filled 36-inch culvert was observedunderneath the railroad track that separates the lagoon from the tidal marsh to the east.The existence of the culvert suggests that the lagoon drained freely into the tidal marshat some time.

In February 1985, DNREC completed a preliminary hydrogeologic investigation of thesalt piles that are on the north side of 1-495 and the site. The investigation concludedthat the salt piles have a significant adverse effect on the quality of local groundwater.High levels of iron, manganese, and sulfates were detected in the samples.

In March 1985, samples from a production well on the Halby site were analyzed to dif-ferentiate the types of cyanide compounds found in the groundwater. The majority ofthe cyanide was from thiocyanate, one of the compounds manufactured by Halby.

In 1986, the City of Wilmington commissioned a study of the storage area just northeastof the tidal marsh and the Halby Chemical site. Groundwater samples were reported tocontain a variety of inorganic and organic compounds. The strontium, nickel, and cobaltlevels found in the groundwater samples and the high concentrations of surfactantsuggest that the pile of petroleum coke east of the site was also contaminating thegroundwater. _______

In October 1988, the initial remedial investigation (RI) work plan for the Halby site wascompleted.

Phase I sediment samples were collected around the site in October andNovember of 1988.

Samples of surface water and soil were collected in November 1988.

Additional soil and sediment sampling began in September 1989 in Phase II.

From February to April 1989, groundwater and soil samples were collected.

A well-elevation survey was completed in March 1989. A second well-elevationsurvey was completed in December 1989.

Also in March 1989, the onsite and adjacent wetlands were delineated by theU.S. Fish and Wildlife Service. On July 18, 1990, the United States GeologicalSurvey (USGS) released a study of tidal influence and connection between thetidal marsh east of the site and the shallow aquifer. The USGS concluded thatthere is a potential for upward migration and discharge from the shallow aquiferto the tidal marsh.

Groundwater sampling was conducted in April and May of 1989.

The EPA Atmospheric Research and Exposure Laboratory collected samples ofonsite ah* from April 4 through 7, 1989. In addition, a regional air-samplingstudy, The Delaware Study, was conducted from July 24 to August 9, 1989, andadditional samples were collected from the Halby site at that time.

The record of decision (ROD) for the Halby Chemical OU1 site was signed in June1991. The EPA entered into a consent decree with Witco Corporation primaryresponsible part (PRP) on December 31, 1991, for performance of remedial design/riskassessment (RD/RA) activities identified in the ROD. The ROD divided the site intooperable units, including the process plant area surface soils (OU1) and the rest of thesite (OU2).

1.3 AERIAL PHOTOGRAPHY REVIEW

In December of 1987, the EPA's Environmental Monitoring Systems Laboratory released their aerialphotograph study. A summary of this study is as follows:

• The analysis of a June 16, 1962, aerial photograph by EPA identifies large stains nearthe north side of the tank-storage area. Also apparent in the photograph is equipmentoperating near a dark mound of material and a dark pool of standing liquid.

• EPA's analysis of a May 6, 1968, aerial photograph notes a large stain covering most ofthe material-storage area and a drainage ditch containing dark liquid connecting theprocess plant area to the lagoon. A dark plume flows from the outlet of the drainageditch into the lagoon.

• The analysis of an April 6, 1973, aerial photograph by EPA notes runoff channels con-necting the material-storage area to the lagoon and a landfilling operation between thematerial-storage area and the lagoon.

• A May 15, 1977, aerial photograph shows that fill has been placed along the northwestboundary of the lagoon, separating a section of the lagoon to form a drainage ditch forroute 1-495. Fill also has been added to the western part of the lagoon. The photographsuggests the presence of a dark liquid flowing from the corner of the material-storagearea down to the lagoon. The landfill was still active in 1977.

• A June 23, 1983, aerial photograph shows an opening in the bank separating the 1-495drainage ditch from the lagoon. The opening appeared to allow the lagoon water to flowthrough the drainage ditch to the Christina River. Considerable clearing and levelinghave been done at the site. The landfill and the disturbed area present in 1977 have beenleveled. The cleared area shows a large number of areas that are either stained or wet.Three parallel lineations that may be trenches appear in one of the cleared areas. Avehicle is parked in one of the apparent trenches. A large part of the northwest side ofthe lagoon has been filled. Many mounds of fill material are scattered around the site.The drainage channel that runs from the tank-storage area and the material-storage areadown to the lagoon has been widened and straightened.

• An aerial photograph taken on November 19, 1987, shows three large piles of whatappears to be construction nibble in the northwest area of the site. The area was beingfilled and leveled at the time. Systematic filling of the onsite lagoon, first noted in the1977 aerial photograph, is visible in the 1983 aerial photograph.

3.0 HAZARD EVALUATION AND CONTROL

3.1 HEAT AND COLD STRESS (REFERENCE CHJM BILL SOP HS4»)

Temperature extremes may present very real hazards for workers who spend significant time work atHalby, especially during the summer months. Workers who wear PPE are particularly vulnerable to heat-related illnesses. Untreated, the symptoms and effects of heat stress grow increasingly serious. A workerwho is not relieved of heat stress may ultimately suffer lift threatening heat stroke. Additionally, workersexperiencing heat stress are at greater risk for other accidents as well. The ability to recognize thesymptoms of heat stress and to avoid the conditions that cause heat stress is essential in protecting thehealth and safety of employees. The procedures listed in Section 3.1.1 through 3.1.7 should be used, hiany combination, to reduce the occurrence of heat stress, and Section 3.1.8 discusses the symptoms andtreatment of heat stress illnesses.

Although most of the work at Halby will occur during the summer months, there is a potential for coldstress when the temperature is 50°F or lower. The most common cold-related disorders are frostbite andhypothermia. The development of frostbite generally requires extended exposure to freezing temperatures,but hypothermia may occur at temperatures well above freezing, particularly if the victim gets wet. Fieldworkers are at risk because of the extended time they spent out-of-doors and because sites are generallyremote from professional medical help. CH2M HELL employees should be aware of the limitations thatcold temperatures place upon workers and adjust work schedules and deadlines accordingly. Sections 3.1.9and 3.1.10 discuss the guidelines for working hi cold temperatures and the symptoms and first aid for coldstress disorders, respectively. ______________________________________3.1.1 GUIDELINES FOR WORKING IN HEAT TEMPERATURE EXTREMES WHILE

Control Measures

Review heat stress in safety meeting. Take resting pulse ratebefore beginning work. Drink 8 ounces of cool water beforebeginning work, and 4 ounces at rest break. Take restbreaks in a cool area. Have ice available.As above, but seated rest break. Monitor pulse rate. (Seebelow.)As above, but rest area to be shaded.As above. Try to provide a shaded work area.As above. Provide a shaded area with seats in the work areafor team members to use as needed. Try to reschedule workto avoid mid-day heat

PULSE CRITERIA. Take resting radial (wrist) pulse at start of work day; record it Measure radial pulse for 30 seconds as restperiod begins. Pulse not to exceed 110 beats per minute (bpm), or 20 bpm above resting pulse. If pulse exceeds this criteria, reducework load and/or shorten the work cycle by one third, and observe for signs of heat stress. No team member is to return to work untilhis/her pulse has returned to <110 bpm, or resting pulse +20 bpm.

3.1.2 FLEXIBLE SCHEDULING

If possible, arrange work activities so that the activities associated with the highest potential of heat stressare conducted during the coolest part of the day. In extreme situations, work activities may have to occurat night to avoid heat. If work is conducted at night, adequate lighting, as defined by OSHA, must beprovided.

100239BC.SEA/7 & B 3 0 I 1 5 8 Revised 8-1-91

-f3.1.3 PERSONNEL ASSIGNMENTS

Rotate personnel and alternate job assignments to minimize overstress or overexcrtion.

3.1.4 ACCLIMATIZATION

Acclimatization can occur after a few days of exposure to a hot environment. NIOSH recommends aprogressive 6-day acclimatization period for workers. Under this regimen, the first day work level islimited to 50% of the eventual anticipated workload and exposure time. An additional 10 percent is addedeach day through day 6. With fit or trained individuals, the acclimatization period may be shortened by2 to 3 days, and work regimens should be adjusted to account for this.

3.1.5 FLUID REPLACEMENT

When enclosed hi an impermeable suit, workers who are physically fit and acclimatized will sweat moreprofusely than unfit or unacciimatized individuals and may therefore'actually face a greater danger of heatexhaustion due to rapid dehydration. This can be prevented by consuming quantities of water periodicallythroughout the work period. To maintain a workers' body fluids at normal levels, the daily fluid intakemust be approximately equal the amount of water lost in sweat. The normal thirst mechanism is notsensitive enough to ensure that water is replaced. Workers should be encouraged to drink more than theyneed when heavy sweating occurs. Water temperature should be maintained at 50° to 60°F. Smalldisposable cups should be provided that hold about 4 ounces. Workers should drink at least 8 ouncesbefore beginning work and then be encouraged to drink at least 4 ounces at each monitoring and restbreak. Workers should also be encouraged to maintain optimal fluid levels when not at work and to stopor moderate their alcohol intake.

3.1.6 TRAINING

Workers should be able to recognize and treat heat stress. Proper training and preventative measures areeffective to avert serious illness and loss of work productivity. Heat stress training should be included hisite-specific training sessions whenever work is performed hi temperatures that exceed 70°F.

3.1.7 COOLING PERSONAL PROTECTIVE DEVICES

Various designs of cooling vests have been developed. Each of these devices compensates for excess heatwith a pre-cooled material, such as ice or an artificial substitute. These vests are usually heavy and havea short effective duration (approximately 1 hour).

• MSA Core Control

MSA is a manufacturing a long underwear-like cooling system (core cool) that uses ice. Micro-tubing is used within the garment to circulate water. The manufacturer states the unit willoperate 2 to 3 hours per ice charge. The suit is attached with an umbilical to an ice watercirculation pump and ice compartment. A back pack model is also available.

• Vortex Tubes

A compressor may supply ah* to a vortex tube for worker cooling.

100239BC.SEA/8 A R 3 0 I 1 5 9 Revised 8-1-91

Supplied Air Coolers

These are supplied air respirators that utilize compressors equipped with chiller units to removewater and excess heat.

• Personal Monitoring DevicesThere are several new personal monitors which are considered to be first generation. One ofthese units is manufactured by Quest Electronics. This consists of a personal unit with atemperature probe that fits into a plug worn in the worker's ear. Studies have found that thetemperature near the ear drum closely resembles the core temperature. When the bodytemperature rises above a pre-set level a light and audible alarm are activated, letting the workerknow that he must rest and cool down. A second unit is produced by Metrosonics. This one hastwo sensors, one that is located on the worker's chest to measure the pulse rate, and anothersensor located under the arm that monitors skin temperature.

• Wetted Cotton Coveralls

Terry-cloth or other cotton coveralls can be a simple and effective auxiliary cooling garmentwhen used with impermeable protective clothing. Under environmental conditions of lowhumidity and high temperatures where evaporation of moisture from the wet cover garment is notrestricted, this approach to auxiliary cooling can be effective, relatively simple, and inexpensiveto use.

5.0 PERSONAL PROTECTIVE EQUIPMENT (PPE)- INTRODUCTION

Personal protective equipment (PPE) ensembles are designed to protect workers from the potential onsitephysical and chemical hazards. They are based on the current knowledge of the site and may change asmore information becomes available. General descriptions of the EPA levels of protection are discussed inSections 5.1 through 5.4. The specific PPE requirements are listed by task in Section 5.5. Because ofanticipated contaminants and their concentrations, the initial level of protection varies; Section 5.6 outlinesthe initial level of protection by task and location.

5.1 LEVEL D-GENERAL

In general, Level D protection is used when low levels of dermal and respiratory protection are required.The following equipment is typically required:

CoverallsBootsHard hatsHearing protectionSafety glasses or gogglesGloves

Level D can be modified when a higher degree of dermal protection is required. The material that thecoveralls, boots, and gloves are constructed of is dependent of site contaminants.

5.2 LEVEL C-GENERAL

Level C protection is used when a higher level of respiratory protection is required. Typically, Level Cprotection also has a higher degree of dermal protection than does Level D. In general, the equipmentrequired for Level C is the same as that required for Level D except an air purifying respirators (APRs) areused. APRs can only be used if the following conditions are met: the atmosphere contains 19.5 to25.0 percent oxygen, there is an approved cartridge for the chemicals that are present, personnel havemedical clearance to wear a respirator, personnel have been fit tested within the past year, and personnel donot have beards.

LEVEL B-GENERAL

Level B protection is used when a higher degree of respiratory protection is required. Situations thatrequire this level of protection include: oxygen deficient atmospheres, atmospheres that have chemicals forwhich APRs are not approved, and atmospheres that exceed the limits of APRs. Typically, Level Bprotection provides higher dermal protection than Levels C and D. The equipment required for Level B issimilar to that required for Level D with the addition of air-supplied respirators. Prior to using Level B,personnel must have medical clearance to use a respirator, must have been fit tested within the past year,and must not have a beard.

5.4 LEVEL A-GENERAL

Level A is used when maximum dermal and respiratory protection are required. The equipment requiredfor Level A is boots and gloves, a fully encapsulating suit, and an air-supplied respirator. Prior to usingLevel A, personnel must have medical clearance to use a respirator, must have been fit tested within thepast year, and must not have a beard. This level of protection will not be used at the site.
