• 1.0 PROJECT DESCRIPTION
The primary objective of this program is to supervise soil sampling for
analysis to determine the presence of coal tar derivatives beneath the Reilly
Tar Site in St. Louis Park, Minnesota. The program includes installation of a
maximum of 18 wells which will be drilled during the performance of this
project. GCA will also construct a data processing computer program that will
be used by Minnesota Pollution Control Agency on existing data files.
Soil cores will be taken at a maximum of eighteen (18) locations on or
near the former Reilly Tar Site in St. Louis Park, Minnesota. Each boring
will be made to bedrock which is approximately' 60 feet below surface level.
Steel pipe and well screen shall be installed in selected well bores for
future monitoring of the ground water.
This drilling program includes three (3) background holes and three (3)
holes in a swamp area with the balance of the holes being on dry, level
sections of the former Reilly Tar Site.
The technical effort has been broken down into the following tasks.
1. Data Management
2. Soil Boring
3. Piezometer Installation
4. Sampling
5. Laboratory Testing
A brief overview of each task is given here. More detail maybe found in
Section 6 of the Work Plan.
Data Management System
GCA will prepare a workable computer program with capabilities of editing
and managing data according to a specified coding system. The software
package will have editing features in proper sequence to aid in stratigraphic
and lithological analyses, hydrogeologic parameters and water quality data.
The operational data base will include.existing data files and will be
formatted in a compatible fashion with the University of Minnesota computer
system for implementation of this information system.
Section 1.0 Revision 0 October 1982 Page 2 of 3
Boring and Soil Sampling
The Subcontractor shall provide the complete hydraulic rotary drilling
unit, all tools, accessories, power, lighting and other equipment, experienced
personnel and all other items necessary to conduct efficient drilling and
coring operations. The Subcontractor shall be properly equipped to collect
and handle cores as specified in the Work Plan. Cores shall be taken at
approximately 5-foot intervals to bedrock in glacial drift using a hollow-stem
auger without drilling mud and split-spoon and/or Shelby tube sampler, and -
installing temporary H-type (4 inch I.D.) casing with nonrecirculated drilling
mud.
Piezometer Installation
The Subcontractor shall provide and install a 2-inch I.D. screened
piezometer in selected holes specified by GCA. It is anticipated that
piezometers will be installed in approximately half of the holes with the
remaining holes to be backfilled. The Subcontractor shall furnish and install
clean sieved sand to approximately 3 feet above the well screen and a mixture
of 6 parts cement and 1 part bentonite, emplaced with Tremi line, to fill the
remainder of the hole. Piezometers emplaced a short distance below the water
table will be backfilled with dry bentonite and sand. These wells will be
fully developed. At the direction of the GCA Field Representative, the
Subcontractor shall perform the following physical measurements on selected
corings that have not been frozen.

3.0 QUALITY OBJECTIVES IN TERMS OF PRECISION, ACCURACY. COMPLETENESS, REPRESENTATIVENESS AND OOMPARATIBILITY
3.1 PRECISION AND ACCURACY
Defined precision and accuracy goals are noL appropriate to the physical
testing to be performed on soil samples in this program. The objective will
be to perform the tests to the specifications provided in the Measurement
Methods'. Section 7 of this Plan lists the methods to be used. The Braun
Companies will provide precision and accuracy goals for Total Organic Carbon
(TOC) analysis of soil samples; this information will be provided as a
revision to the QA Plan.
3.2' COMPLETENESS, REPRESENTATIVENESS AND COMPARABILITY
The onsite supervision, the QC Measures outlined in this Plan and the
responsible QA/QC personnel should ensure that a high percentage of total
measurements made are valid measurements. However, soil sample are difficult
to work with and some may be lost in handling. The objective is to have
85-90% of the total measurements made be valid measurements.
GCA'S Field Technical Representative will identify drilling and sampling
sites which are representative of the area being sampled. The use of standard
testing methods, listed in Section 7 of this Plan, will ensure that the test
results are comparable with results of the same tests performed on the same or
similar samples.
Section 4.0 Revision 0 October 1982 Page 1 of 3
4.0 SAMPLING PKOCEUUKES
4.1 SAMPLING PLAN
The objective is to sample the soil that underlies the Reilly Tar Site
for physical testing and for chemical analysis to determine the presence of
coal tar derivatives at the site.
4.2 SAMPLE COLLECTION PROCEDURES
4.2.1 General
a. Cores of the materials penetrated during boring operations
will be collected at intervals of approximately 5 feet, at changes in
lithology, and at depths directed by the GCA Field Representative who will
also determine the type of sampler to be used for each sample.
4.2.2 Split-Spoon Sampling
a. The 3-inch I.D. split-rspoon samplers will consist of three
sections of 12, 6, and 6 inches, respectively. In order to facilitate
extrusion of the cores from the liners, the Subcontractor will provide a
special tip such that the internal diameter of the tip is reduced-by twice the
thickness of the liner wall. In addition, the Subcontractor will supply a
commercial, spring loaded retaining ring which, at the direction of the GCA
field representative will be inserted between the barrel and the sampler tip.
All split-spoon samplers will be fitted with segmented brass or stainless
steel liners. The liners will consist of three segments of 12, 6, and 6
inches each to be provided by the Subcontractor.
The samplers and liners will be thoroughly washed in water and rinsed in
hexane in the laboratory of the Subcontractor prior to each use. The
split-spoon sampler will be washed with clean water and both the sampler and
the liners rinsed in hexane provided by the Subcontractor in the field
immediately prior to use. After the sample is taken and the liner is removed
from the sampler, the Subcontractor will store the liners in a clean, enclosed
work area provided by the Subcontractor.
• ^ Section 4.0 Revision 0 October 1982 Page 2 of 3
«
In the clean area, the Subcontractor will extrude the sample into clean,
sterile, labeled, glass jars provided by the Subcontractor. The GCA Field
Representative will then proceed to log the core samples. After logging, the
Subcontractor will store the jars in d^ ice until shipment. S^lmples with
excessive amounts of moisture may require partial dry ice freezing prior to
extrusion from the liner sections.
b. The sampler will be driven by a 300^ound hammer having a
30-inch drop. The number of blows required for each 6 inches of penetration
will be recorded by the Subcontractor for 24 inches of penetration. The
subcontractor will supply certification of the weight of the 300-pound hammer.
c. Once every 2 weeks, the Subcontractor will ship the processed
cores packed with dry ice and packaged in conformance with EPA National
Enforcement Investigation Center (NEIC) and Department of Transportation (DOT)
requirements. Prepaid shipment will be made in locked coolers via a
DOT-approved carrier to GCA/Technology Division, 213 burlington Road, Bedford,
Massachusetts 01730 (Attention Sample Bank).
4.2,.3 Thin-Wall Sampling
a. At locations and depths to be determined by the GCA Field
Representative, undisturbed samples will be taken with a thin-walled, open
drive tube sampler.
b. The 3-inch (O.D.) by 36-inch samplers will be constructed of
seamless steel, with a 14 gauge wall thickness, and a bit clearance not
greater than 0.5 percent.
c. The drill rig should be provided with a hydraulic pressure
device capable of exerting a driving force of 8,000 pounds.
Section 4.0 • Revision 0 October 1982 Page 3 of 3
d. The sampling tube and sample head must be smooth and
thoroughly cleaned inside and outside before sampling and must be in proper
working condition. The tube edge must be properly sharpened and have the
correct inside clearance for the soil being sampled.
e. The drive should be made without rotation and with a
continuous stroke. No additional drive will be attempted after the s^pler
stops.
f. The sampler containing the soil sample will be carefully
removed from the hole and shipped to the Subcontractor's laboratory for
testing. For this purpose, the tube ends will be sealed with expanding
packers.
Section 5.0 Revision 0 October 1982 Page 1 of 10
5.0 SAMPLE CUSTODY PROCEDURES
GCA'B QA Manager will oversee the implementation of the chain of custody
and document control procedures described in this section. These procedures
follow the NEIC guidelines presented in References 1 and 2.
3.1 GENERAL
After geologic logging of the cores by the Technical Representative,,
samples collected in the field will be immediately cooled to approximately 4°C
with ice and stored in styrofbam coolers. Samples for shipment to GCA's
laboratory facility will be frozen with dry ice and maintained in a secure
freezer,. Samples for soil testing will be maintained in a secure location
away from other samples until testing is complete.
The following steps will be followed by the Subcontractor to ensure
sample integrity and validity from the point of sampling to safe storage in
the laboratory.
1. The number of people involved with handling the samples will be kept at a
minimum. David Vieau will serve as Sample Custodian.
2. Samples will be obtained using standard approved field techniques
detailed in Section 4.of this Plan. Any deviations due to site
conditions, weather, etc. will be reviewed with the GCA Technical
Representative to obtain approval and notations made in the Field Log and
initialed and dated.
3. Every sample taken will have a unique identification tag attached to the
sample container. The tag will contain such information as the project
number, sample number, date, source or site of sampling, preservatives
used and the name of the person who took the sample (Sampler); sample
tags and custody records are discussed in more detail in Section 3.2 and
5.3.
Section 5.0 Revision 0 October 1982 Page 2 of 10
4« A chain of custody form will be used to record tlie following
information:' project number, Sampler's name and signature, ample
identification, site or location of sampling, data and time, type of
sample matrix, type of container, preservative steps taken, method of
shipment and requested analysis.
3. The field Sampler has total responsibility for the samples until such
time as sample custody is transferred to another responsible person
involved in the next step of sample transport to the lab.
6. After sampling is completed, the samples will be packed in ice in a
transfer container (typically a styrofoam cooler inside a heavy cardboard
box). The transfer container will be secured against tampering or
spillage. Every effort will be made to expedite the shipment of samples
to the lab and maintain sample environment as close to ^''C as possible.
7. Upon arrival at the Subcontractor laboratory, the designated Sample
Custodian is responsible for evaluating the condition of the samples with
respect to:
a. integrity of containers and seals,
b. condition of sample matrix and,
c. completeness of chain of custody information.
Once satisfied that the samples are valid, the Sample Custodian will sign
the chain of custory form signifying acceptance for analysis or
shipment. Should there be a question about sample integrity or
information received on the chain of custody forms, the samples must be
held in abeyance pending the resolution of the question as noted in
Section 5.2 of this Plan.
8. Once received in the Subcontractor laboratory, samples will be logged and
scheduled for analysis or shipment and remain in sample storage until
such analysis or shipment is performed.
9. Samples shipped to GCA will be handled as described in Step 7 above by
the GCA Sample Bank Manager.
Section 5.0 Revision 0 October 1982 Page 3 of 10
5.2 CHAIN OF CUSTODY PROCEDURES
5.2.1 Sample Identification
Sample collection tags will be preprinted to insure that the
required information is provided on each tag. Each collected sample,
including duplicates and field blanks, shall have a completely filled iii
sample tag securely attached to it. Duplicates and field blanks shall be
identified in the remarks section on the reverse side of the tag. (See
The person who physically collects the sample is the Sampler who
signs the sample tag. He may presign the tag if he will be in a hazardous
condition when sampling. The exact time of sample collection will be recorded
and all team members present shall be recorded in the field log book. The
Sampler initiates the custody record for transfer of samples.
The Subcontractor Sample Custodian or the GCA Technical
Representative will maintain a bound sample log listing all samples collected
and their respective tag numbers and disposition of the samples to the
laboratory for analysis. The onsite trailer or van will operate as a sample-
bank with new sample tags assigned to the blank or duplicate samples so that
they are not recognizable to the testing laboratory as blanks or duplicates. I
5.2.2 Sample Transfer/Custody Records
Customized record sheets following NEIC format will be provided by
the Prime Contractor for this project. They are two-part carbonless copy
forms which correlate with the sample identification tags. (See F^ure 5-2)
Requested information has the same heading on both. On this project the
custody record will document transfer of samples to the Subcontractor
laboratories, to storage in a freezer maintained at the Subcontractor
headquarters, and shipment of samples to GCA's laboratory. Internal
laboratory records will then track the samples.
-The custody records will be used for a packaged lot of samples.
More than one sample will usually be recorded on one form; more than one
custody record sheet may be used for one package. Their purpose is to

document the transfer of a group of samples traveling together; when the group
of samples changes, a new custody record is initiated. The original of the
custody record will always travel with the samples. The initiator of the
record will keep the copy. Vftien custody of the same group of samples changes
hands several times, some people will not have a copy of the custody record. '
This will be acceptable as long as the original custody record shows that each
person who had received custody has properly relinquished it.
5.2.3 Using the Custody Record
The Sampler will fill in all requested information from the
sampling tags. The person receiving custody will check the s^ple tag
information against the custody records, he will also check sample condition
and note anything unusual under remarks on the custody form.
The originator (Sampler) will sign in the top left "Relinquished
by" box and keep the copy. The person receiving custody will sign in the
adjacent "Received by" box and keep the original. The date/time will be the
same for both signatures since custody must be transferred to another person.
When custody is transferred to an analytical laboratory, blank
signature spaces may be left and the customized last "Received by" signature
box must be used. The unused signature boxes may be lined out to show they
were not used. In all cases, it must be readily seen that the same person
receiving custody has relinquished it to the next custodian.
5.2.4 Shipped Samples
Whenever a group of samples along with its custody form is to be
shipped, the samples will be accompanied to the carrier so that if requested,
the number and identification of the samples can be verified. The commercial
carrier is not required to verify this nor to sign the custody records.
Receipts of bills of lading will be maintained as part of the permanent
documentation. The package will be closed with strapping tape and custody
seals so that the carrier is transporting a secure container. The person
receiving custody of shipped samples will be required to document the
condition of the strapped and sealed box upon arrival.
Section 5.0 Revision 0 October 1982 Page 7 of 10
5.2.5 Laboratory Custody
The onsite trailer or van, the Subcontractor's and GCA's
analytical laboratories are considered to be working laboratories. Each will
have a designated Sample Custodian who accepts custody of the samples and
implements a system to maintain control of samples within the laboratory. The
laboratories will not be open to the general public and will have access
restricted to employees known to each other. Each handling of the sample to
renumber, subdivide, preserve, etc. will not be documented in this situation*
5.3 DOCUMENT CONTROL PROCEDURES
The purpose of document control is to insure that all project documents
will be accounted for when the project is complete. GCA has designated Pablo
Huidabrp as Document Control Officer (DCO) for this project; Braun Companies
have designated David Vieau as their DCO. As appropriate, both will be
responsible for issuing, controlling and maintaining records of controlled
documents.
At the conclusion of the project, the Subcontractor will provide all
controlled documents with records to GCA for inclusion in their overall
Project Document Inventory. The Braun Companies DCO shall maintain the log of
all serialized documents used. If any of these controlled items are damaged,
lost or voided, this will be so noted in the log. In addition, the DCO will
serve as sample custodian for samples collected in the field.
Each key technical person working on the project will be required to
maintain an individual project log book. One field log book for each drilling
team will be maintained. The project numbering system is outlined below.
5.3.1 Project Code
The project code for the Reilly Tar study is RT 1-619-078. This
number will appear on sample identification tags, custody records, log books,
field data sheets, driller logs, core logs, project memos and reports,
document control logs, corrective action forms and logs, QA plans and all
Section 5.0 Revision 0 October 1982 Page 8 of 10
other project records. In addition, the Contractor code will be placed oii all
documents except sample collection tags and custody records. (See Section
5.3.3 below)
5.3.2 Preserialized Documents
Sample collection tags and custody records will have preprinted .
' serial numbers on them. It is not necessary that a tag number match a custody
record number. It is necessary that the Subcontractor DCO maintain records
which account for all serially numbered items received from GCA. If tags or
custody records are damaged, lost or destroyed before used for their purpose,
the serial number of the item and its disposition must recorded.
5.3.3 Other Documents
Other documents will use a numbering scheme similar to that
identified herein to enable unique identification of each item. The numbering
scheme includes the project code, contractor code, document code and serial
number as shown below.
Project Code Contractor Code Document Code Serial Number
-OI-(GCA)
RT 1-619-078 -02-(Braun) -A- -00001
Table 5-1 presents a suggested document code. The Subcontractor's
DCO will finalize the system to be used for their documents; it is desirable
that suggested document codes be used to facilitate compiling the overall
Project Document Inventory.
At the conclusion of the project the Subcontractor DCO will
account for all project documents and number them, and a contents listing of
the documents will be prepared. The Subcontractor will photocopy any
documents it wishes to retain in its project file. The DCO will keep a copy
of the contents listing and place one copy in a shipment box containing the
original dociiments. The complete Braun Project Document Inventory will then
be shipped to GCA.

8.0 DATA REDUCTION, VALIDATION AND REPORT
8.1 DATA REDUCTION
I
Braun Companies will document .the data reduction and .reporting procedures
they will use for physical testing and TOC analysis of soil samples. This
information will be included in the QA Plan Revision.
6.2 DATA VALIDATION
Data validation is the process of filtering data and accepting or
rejecting it on the basis of sound criteria. GCA/Technology Division and
Braun Companies supervisory and QC personnel will use validation methods and
criteria appropriate to the type of data and the purpose of the measurement.
Elecords of all data will be maintained, even that jud^^ed to be an "outlying"
or spurious value. The persons validating the data will have sufficient
knowledge of the technical work to identify questionable values.
GCA'S Technical Representative will validate the Drillers logs onsite and
initiate any corrective action necessary to obtain complete and correct data.
The Braun Companies staff will validate physical testing and TOC analysis
results. GCA's Project Manager will review and validate all the field data.
8.3 IDENTIFICATION AND TREATMENT OF OUTLIERS
A data point which deviates markedly from others in its set of
measurements may be referred to as an outlier. An outlier may result- from an
error in the measurement system or technique, or it may be a valid value due
to unique circumstances at the time of sampling, analysis, or data
collection. A suspected outlier value will be recorded and retained in the
data set while it is investigated.
Drillers logs, field and laboratory notebooks will be checked to see if
they indicate any unique circumstances which occurred during drilling,
sampling or testing. A simple statistical test will be performed on suspected
outliers: GCA/Technology Division staff members usually use one or both of the
following tests to identify outliers.
Section 8.0 Revision 0 October 1982 Page 2 of 3
1 2 Dixon s test for extreme observations ' is an easily computed
procedure for determining whether a single very large or very small value is
consistent with the remaining data. The one tailed t test for difference
may also be used in this case. The calculation formats and tables of critical
values given in Reference 2 will be used for these tests. It should be noted I
that these tests are designed for testing a single value. If more than one
outlier is suspected in the same set of data, the statistical sources listed
)in References 1 through 6 are consulted and the most appropriate test of
hypothesis is used.
If the suspect value is statistically identified as an outlier, further
investigation will be initiated. The operator, analyst, or data gatherer who
worked with the sample will be consulted for his knowledge of the specific
sample and his experience with similar samples. This may give an experimental
reason for the outlier and a decision can then be made as to whether the
outlying value should be kept in the data set.
Further statistical analyses are performed with and without the outlier
to determine its effect on the conclusions. In many cases, two data sets will
be reported, one including and one excluding the outlier.
8.4 DATA REPORTING SCHEME
The data reporting scheme and key people who will handle the gathering
and evaluation of data are shown in Figures 2-1 and 2-2, the Project
Organization Charts.

9.0 INTERNAL QC MEASURES
Use of Project Workbooks—GCA has found the use of bound workbooks to be
a valuable QC measure to facilitate the completeness and accuracy of project
documentation. Workbooks have been assigned to key technical personnel as
noted below and will be used to make notations of pertinent information such
as telephone and other conversations, meetings, significant references,
.process information, calculations, etc. The workbook assignments for this
Task are as follows:
• Arlene Levin 1-619-078-01
• Pablo Huidobro 1-619-078-02
• David Cogley 1-619-078-03
• Dan Goode 1-619-078-04
• Nancy Krusell 1-619-078-05
• Russell Wilder 1-619-078-06
The overall Program Manager, Thomas Hopper, will maintain a log of all
workbooks issued on this task so they can be identified and located. The Task
Manager is responsible for all workbooks used on his work assignment and will
indicate in the Master Log their disposition and location upon completion of
the work assignment.
The Braun Companies DCO will issue and control project workbooks used by
key technical staff members. All project workbooks will be included in the
Project Document Inventory.
9.1 WELL DRILLING, GEOLOGIC LOGGING, PIEZOMETER INSTALLATION
The specifications in the work plan for constructing borings and
piezometers will be strictly adhered to. Recording' of geologic information
from the drilling operation and from samples obtained will be conducted by the
Section 9.0 Revision 0 October 1982 Page 2 of 4
Field Representative, Pablo Huidobro, a trained geologist. Field Logs will be
checked periodically by the Project Manager, Rusell Wilder, also a trained
geologist.
9.2 SAMPLE OOLLECTION
Samples will be collected as directed by the Technical Representative and
as detailed in Section 4 of this Plan. The specified sampling equipment and
saitiple containers will be cleaned as described in Section 4 before use on
samples. Sampling equipment will be cleaned in the field before each use. QC
measures will include blanks and duplicates as described below.
1. Procedural Blanks—To monitor sampling equipment cleanup. After every tenth split-spoon sample has been collected, 100 to 200 ml deionized water will be used to rinse a clean sampler and liner. The water will be collected in a clean sample container of the same type used for field samples and processed as a field sample. The Sampler will note on the sample tag and in the field log that the sample is a procedural blank.
2. Field Blanks—To monitor general sample handling, including container cleanup. On each split-spoon sample collection day, 100 to 200 ml deionized water in an appropriately cleaned sample container of the same type used for field samples will be brought to the field and processed as a field sample. . The Sampler will note on the sample tag and in the field log that the sample is a field blank.
3. Field Duplicates—To estimate precision of the overall measurement process. Ten percent of the split-spoon samples and the thin^alled tube samples will be collected in duplicate. The Technical Representative will identify the sites where duplicates will be collected; the Sampler will note on the sample tag and in the field log that the samples are duplicates.
9.3 PHYSICAL MEASUREMENTS AND TOG ANALYSIS
Physical testing will be performed on soil samples using the methods
specified in Section 7 of this Plan. The person responsible for analytical QC
will ensure that each person working on the samples documents all testing or
analytical work in an individual laboratory notebook or a project laboratpfy
notebook. Each notebook page shall be identified by the Project Code
(RT-1'619-078) and dated and signed by the analyst.
Section 9.0 Revision 0 October 1982 Page 3 of 4
Sample and standard preparation and dilution, instrument operating
conditions, and calibration curves will be documented in notebooks or
instrument logs. All raw data pertaining to this project will be identified
with the Project Code and will form part of the Project Document Inventory.
Standard laboratory QA/QC procedures are briefly discussed below; they
will be applied as appropriate to the project work.
Class A volumetric glassware will be used throughout wherever volumetric
dilutions or transfers are required. All processes calling for nonvolumetric
glassware will be performed in borosilicate labware. The cleaning process of
the various types of laboratory glassware and sampling containers will' be
specified to eliminate interferences due to contamination. All glassware will
be detergent washed followed by tap water and deionized water rinses. Pipets
and other glassware which may become coated with organic films will be
subjected to an alcoholic potassium hydroxide bath for 24 hours followed by an
acid bath (diluted hydrochloric acid) for 4 to 6 hours, and tap and deionized
water rinses.
AIL reagents used will be analytical reagent grade and, where
appropriate, spectroquality reagents will be utilized. Laboratory deionized
water must pass ASTM Type II water specifications (ASTM D1193-74). Standard
curves in the expected concentration ranges of the samples t-o be analyzed will
be run each day to standardize the instruments. Random standards will be. run
periodically during analysis to check for drift in instrument response. The
analytical curve will also be run after all samples have been analyzed as a
final check on the stability of instrument response. QC measures will include
blanks, duplicates and spiked samples as described below.
1. Deionized laboratory water blank will be run after every 10 field samples to monitor the overall analytical system.
2. Reagent blank—To determine background effect or contamination caused by the reagents used in sample preparation and analysis. One reagent blank will be processed with each block of 10 field samples analyzed by a particular method.
3. Laboratory duplicates—To estimate precision of- the testing or analytical work. TVo aliquots from 1 field sample in each block of 10 samples analyzed by a particular method will be carried through the entire testing procedure.
Section 9.0 Revision 0 October 1982 Page 4 of 4
4. Spiked samples—One field sample from each block of 10 samples analyzed by a particular method will be artifically spiked with analytes found in the unspiked field sample. The spiking level will be approximately 50 percent greater than the level found in the unspiked sample.
Acceptance limits will be established for these blanks and spiked sampls;
if these limits are exceeded, corrective action will be initiated. Sample
^ results will be blank-corrected, unless corrective action indicates this
should not be done. Corrective actions will be documented and approved by the
responsible QA/QC person.

10.0 QUALITY ASSURANCE PERFORMANCE AUDITS, SYSTEM AND FREQUENCY
GCA/Technology Division's quality assurance program includes both
performance and system audits as independent checks oL the quality of data
obtained from sampling, analysis, and data gathering activities. Every effort
is made to have the audit assess the measurement process in normal operation.
Either type of audit may show the need for corrective action.
I
10.1 PERFORMANCE AUDITS
The sampling, analysis, and data handling segments of a project- are
checked in performance audits. A different operator/analyst performs these
audit operations to ensure the independence of the quantitative results. The
Braun Laboratory QC Coordinator will direct the inclusion in the sample load
of QC samples so that they are not recognizable to the analyst. In this
project, performance audits are only appropriate to the TOC measurements made
on the soil samples.
10.2 SYSTEM AUDITS
A system audit is a qualitative review of project work to ensure that the
planned QC measures are in use and are functioning effectively.
GCA personnel onsite will ensure that the sampling procedures and chain
of custody procedures identified in this QA Plan are followed; a formal audit
report will not be prepared. GCA's QA Manager will conduct a system audit
during the program and prepare a written audit report which will be included
dn the appropriate monthly report and in the QA section of the Final Report.
10.3 AUDITS EXTERNAL TO GCA
GCA will cooperate fully with any system or performance audits arranged
by EPA. The QA Manager will aid in scheduling as required.

11.0 PREVENTIVE MAINTENANCE PROCEDURES AND SCHEDULES
GCA/Technology Division follows an orderly i?rogram pf positive actions to
prevent the failure of equipment or instruments during use. This preventive
maintenance and careful calibration helps to assure accurate measurements from
field and laboratory instruments.
;11.I DRILLING AND SAMPLING EQUIPMENT
The GCA Field Representative will ensure that all drilling and sampling
equipment is in proper working condition and is maintained in that condition
throughout the performance of this program.
11.2 PHYSICAL TESTING AND TOC ANALYTICAL EQUIPMENT

12.0 ROUTINE PROCEDURES USED TO ASSESS DATA PRECISION, ACCURACY AND COMPLETENESS
12.1 PRECISION
Overall measurement precision will be determined by the collection and
analysis of replicate soil samples for TOC analysis. The analysis of
laboratory duplicates (replicate aliquots from one collected sample) will
enable the estimation of analytical precision. Precision will be expressed as
the standard deviation, s, which is determined according to the following
equation:
jr±5H N-l
where S <* standard deviaton
X}^ ° individual measurement result
N ° number of measurements
Relative standard deviation may also be reported. If so, it will be
calculated as follows:
(1) RSD = 100
where RSD > relative standard deviation, expressed in percent
S standard deviation
X arithmetic mean of replicate measurements
12.2 ACCURACY
Accuracy will be estimated from the analysis of "blind" QC samples whose
true values are known to the Laboratory QC Coordinator. Accuracy will be
Section 12.0 Revision 0 October 1982 Page 2 of 2
expressed as percent recovery or as relative error. The formulas to calculate
these values are:
Percent Secoveiy - 100^ j
/Measured Value - True Value
j^Measured Value\
Relative Error " lOOl True Value
p. 3 OOMPLETENESS
Completeness will be reported as the percentage of all measurements made
whose results are judged to be valid. The procedures to be used for
validating data and determining of outliers were described earlier in this QA
Plan. The following formula will be used to estimate completeness:
C » ICQ
where C " Completeness expressed in percent
V " Number of valid measurements
T " Total number of measurements
Section 13.0 Revision 0 October 1982 Page 1 of 1
13.0 OOKRECTIVE ACTION
The Subcontractor will assign responsibility for initiating corrective
action on each aspect of project activity. The Technical Representative,
Pablo Huidobro, or other designated individual, will observe aR field
activities and initiate corrective actions as necessary.
All corrective- actions taken will be documented in laboratory notebooks
,or project workbooks or on Corrective Action Forms; the project code
(RT-1-619-078) will identify the written description of the problem found and
the actions taken. The documentation will be subiaitted as part of the Project
Document inventory.

14.0 QUALITY ASSURANCE REPORTS TO MANAGEMENT
14.1 INTERNAL GCA REPORTING
I As noted in Section 2, GCA'a Geotechnical QC Coordinator will report on
an ad hoc basis to the QA Manager whenever a problem or question arises.
All Corrective Action Forms are submitted to the QA Manager for initial
approval of the corrective action planned and a copy is provided to the
Department Manager. All system audit reports are provided to the Project I
Maxuger, Department Manager and the Technology Division General Manager.
14.2 BRAUN COMPANIES REPORTING
The individuals responsible for QA/QC implementation are identified in
Section 2 of this Plan. They will provide to GCA all QC sample results and
documentation of any problems encountered and corrective actions taken.
