EXECUTIVE SUMMARY

Sharp and Associates. Inc. (SHARP) has completed the field work necessary to submit this DataTransmittal Report, w h i c h presents the data and results obtained dur ing the Saginaw Aquifer 2001Drilling Program. The wells were installed on behalf of the Motor Wheel Disposal Site (MWDS)Potentially Responsible Parties (PRP) Group. As described in Section III Tasks of the Long TermStatement of Work (LT-SOW), the installation of the Stage 1 SDWA monitoring wells (LT-SOW SectionII .A) was required. In addi t ion, monitoring we l l s were installed under the Comprehensive EnvironmentalResponse and Compensation Liabi l i ty Act (CERCLA). For efficiency and to ensure consistent data, theinstallation and data collection results of both the Stage 1 monitoring wells and CERCLA monitoringwells are included in th i s document.

The LT-SOW required a work plan for the instal la t ion of the Stage 1 SDWA monitoring wells (LT-SOWSection II .A) . The approved Final Work Plan included procedures for:

• Locating the Saginaw Aquifer monitoring wells;• The technical dr i l l ing approach and technique for establishing monitor well installations;• Vertical profiling and hydraulic testing the Saginaw Section in each of the boreholes;• Geophysical logging of the boreholes;• Open hole aquifer testing; and• The collection and analyses of groundwater samples.

The mechanism used for changes to the work plan was the Field Change Order (FCO). There were nineapproved FCOs during the fieldwork that were adaptations to the work plan based upon conditionsencountered during field operations.

The additional work conducted during the 2000-2001 drilling program has refined the definition ofMWDS related contamination within the Saginaw Aquifer. This report presents the data collected duringthe 2000-2001 drill ing program concerning the stratigraphic and hydraulic characteristics of the SaginawAquifer and also the nature, occurrence, extent, and migration of contaminant materials within theaquifer.

Based on the current groundwater plume definition, groundwater modeling, and the understanding of theSaginaw Aquifer, these new Saginaw Aquifer monitoring wells will fulf i l l the requirement in the LT-SOW for Stage 1 monitoring wells. They will also provide additional long-term Saginaw Aquifermonitoring wells under CERCLA.

SECTION 1.0 INTRODUCTION

1.0 INTRODUCTION AND GENERAL SCOPE OF WORK

On July 29,1999, the U. S. Environmental Protection Agency. Region 5 (USEPA) issued an EmergencyAdministrative Order pursuant to Section 1431 of the Safe Drinking Water Act (the Order) to W. R.Grace & Co. (GRACE). The Order requires the development, USEPA approval, and implementation ofmeasures including interim measures as well as long-term measures. The Interim Measures Statement ofWork (I-SOW) was approved in March 2000. The Long Term Statement of Work (LT-SOW) wasfinalized in December 2000. A work plan was approved for the installation of four Stage 1 SDWAmoni tor ing wel ls (LT-SOW Section II .A). In addition, four of the monitoring wel l s discussed in th i sreport were installed under the Comprehensive Environmental Response and Compensation L iab i l i ty Act(CERCLA). For efficiency and to ensure consistent data presentation and interpretation, the results of theStage 1 monitoring we l l s and CERCLA monitoring wells are reported here. The fol lowing tablesummarizes the work completed.

* MW-87 was re-tested using a constant rate pump test, per FCO #9. The initial step test data from3/19/01 was inconclusive because of insufficient drawdown.** The borehole collapsed at MW-93 between the 91 foot casing point and 97 feet. A second, 6-inch casingstring was installed to a depth of 115 feet during the week of April 16-20.

1.1 Locations of the New Saginaw Aquifer Monitoring Wells

The approved, final well locations were established to comply with access, util i ty clearances, andrestrictions within the City of Lansing dri l l ing permit (trees, restoration, etc.). The final locations areshown on attached Figure 1. A description of each monitor well location and the objectives of each wellare as follows:

* MW-87 (SDWA well, located between Larch and Cedar streets, north of Liberty Street) was thefirst well drilled as part of this program. The objective of this well is to delineate the western side ofthe plume as a sentinel well for the SWDA order. During the review of the City of Lansing's

uikJ Aisitciatts. fin 1-1

property maps on December 7, it was discovered that the MW-87 location occurred on propertyowned by the Michigan Department of Transportation (MDOT). A permit was obtained fromMOOT for the installation of this well on December 12. 2000.

• MW-88 (located on Thompson Street, between Benjamin and Douglas Streets). This well locationwas moved from the original proposed location because of access and property ownership issues.The final location was decided in the field on December 8, 2000, by MDEQ, Layne-Northern andSHARP (FCO #4). The objective of the well is to delineate the western side of the plume as asentinel well for the SWDA Order.

• MW-89 (North Side of Eureka Street, just east of Hosmer Street). The objective of the we l l is toprovide sentinel w e l l coverage north of BW&L production wel l 30-6 and northeast of BW&Lproduction well 25-10 for the SWDA Order.

• MW-90 (South of North Street and east of Turner Avenue along the Penn Central tracks). Theobjective of the well is to provide a sentinel well to the east of BW&L well 25-21 for the SWDAOrder. The final location of MW-90 was resolved in the field by MDEQ. Layne-Northern andSHARP, and was based on utilities, access and property ownership issues.

• MW-91 (Handy - Case Streets). The objective of the well is to further define the western side ofthe plume as a delineation monitoring well for CERCLA. This location is just inside the capturezone of SEW-1 as it is defined in the groundwater model with a pumping rate of 100 gpm.

• MW-92 (Case - Porter Street). The well has further defined the southwestern side of the plume, andis a monitoring well for CERCLA. This location is just outside the capture zone of SEW-1 asdefined in the model with a pumping rate of 100 gpm.

• MW-93 (Twinned location to existing well MW-55). This CERCLA monitoring well has furtherdefined the vertical extent of ammonia at this location. MW-55 partially penetrates the top of theSaginaw Aquifer.

• MW-94 (Lake Lansing Road - East Street) The objective of this well is to monitor capture betweenSEW-1 and SEW-2 for complete capture of the contaminants for CERCLA. The location is alsoproviding water level measurements. This well can also be converted to an extraction well at afuture date if needed.

1.2 Monitoring Well Drilling and Completion Procedures

The Saginaw Aquifer monitoring wells were drilled in stages with intermediate isolation casing to precludethe potential for either cross flow or cross contamination between the Saginaw Aquifer and the overlyingGlacial Aquifer. To accomplish this prescribed well design, all drilling was conducted using a BarberDrilling Rig and a combination of 13-inch dual wall reverse circulation (DWRC) drilling and 4 V8-inch dualair rotary drilling.

The 13-inch diameter drive-casing borehole was drilled from surface, through the entirety of theunconsolidated and glacial sedimentary sequence. A water sample was taken when the dril l cuttings andother indicators such as dr i l l ing rate identified the weathered unconformity at the glacial-bedrock interface.A "Decision Tree" was developed to guide this field sampling procedure, as was presented in theapproved Work Plan. The sample results are presented in Appendix D of this report.

!\hurp and Associates, IIK

The 13-inch borehole was terminated in competent, unweathered Saginaw Sandstone. Following thetermination of the 13-inch diameter borehole, an 8-inch string of steel well casing was installed. Afterverifying that the casing was true and plumb the 8-inch casing string was tremmie grouted into place usingneat cement grout. The casing grout was allowed to cure for 24 hours. The casing string was pressure testedto maintain the in i t ia l 6-10 psi casing pressure for a period of thirty (30) minutes. None of the eight installedcasing strings failed the test.

The 4 V«-inch bedrock borehole was advanced to a total depth of 400 feet below ground level (bgl) in everywell as required by the approved Work Plan. This 400-foot total depth is the same as the total depthsestablished during the 1997 Saginaw dr i l l ing program. Following the completion of the 400-foot deep openborehole, the dri l ler circulated air through the hole to remove cuttings and to develop the wel l .

There was an FCO in completion procedures for well MW-93 to accommodate an additional casing string(FCO #7). The problem was caving formation in the open well bore in the interval just below the base of the8-inch casing. Some washout just below the base of the casing occurred in all of the wells but in MW-93 anadditional casing string to seal off that interval was warranted. Lithology logs and completion diagrams arecontained in Appendix A of this report.

1.3 Field Change Orders

All of the dr i l l ing testing and installation procedures closely followed those described in the approvedWork Plan. Any deviation from the Work Plan was discussed with all participants and agency personnel,and then the approved change was documented in a series of field change orders (FCOs). The FCOs areattached in Appendix B of this report and summarized here.

There were a total of nine FCOs completed during the installation of these wells. FCO #1 was a minorchange in the sequence of drilling of the wells. The original well number-location relationship waspreserved. FCOs #2 and #3 documented changes to the logging program. FCO #4 documents the finallocations of the wells based upon rig access and actual field conditions. FCOs #5 and #6 were changes inthe hydraulic testing program. FCO #7 was a change in completion procedures for well MW-93 toaccommodate an additional casing string. The problem was caving formation in the open well bore. FCO#8 documents the approval to drop the BIPS tool from the logging program for the last 4 wells. FCO #9was the addition of a constant rate aquifer test performed in well MW-87. The data set from the step testhad insufficient drawdown to quantify the transmissivity of the aquifer in the area of this well.

1.4 Equipment Decontamination

Large equipment that was used in the work zone at each well was first taken to the MWDS fordecontamination. The driller cleaned the back of the drill rig and all downhole drilling and samplingequipment using a high-pressure, steam wash uni t prior to the commencement of dr i l l ing activities ateach boring location. There was a temporary decontamination pad constructed adjacent to the MWDSTreatment Plant. Sampling pumps were cleaned using City (potable) water. Decontamination consistedof a Liquinox and water wash, followed by a clean City water rinse. Following decontamination of thesampling pump(s), field personnel collected an equipment rinse sample by rinsing the pump assemblywith laboratory grade distilled water. All decontamination water was transferred to the sump in thetreatment building for processing through the treatment system.

All reusable PPE and hand tools were cleaned by performing a wash with tap water and a Liquinoxsolution, followed by a rinse with tap water. Disposable equipment was bagged and properly disposed.

1.5 Waste Handling and Disposal

All wastes generated during site activities were containerized and i n i t i a l l y staged at MWDS. Wastehandl ing and disposal was completed in accordance wi th the fo l lowing approach.

Solid Waste

All soil cuttings generated dur ing d r i l l i n g act ivi t ies were placed into roll off containers located at eachwell location. Each roll off container was l ined with plastic and covered wi th a waterproof tarpaulin. Therolls off containers were staged at MWDS upon completion of each well installation. Field personnelcollected composite soil samples from each roll off container upon the completion of each d r i l l i n g phase.The composite sample was analyzed to measure concentrations of Volat i le Organic Compounds (VOCs).Following the receipt of the VOC analysis, the analytical results were sent to The Environmental Quali tyCompany (EQ) for verification of material approval. Once verbal approval was received by EQ, the rolloff boxes were transported for disposal at the Michigan Disposal Treatment Plant in Bellevil le. Michigan.The soil cuttings were wet, and so they were solidified with lime prior to transportation.

1.5.2 Eiquid Waste

Equipment decontamination water and produced groundwater from the wells was contained in a temporarydecon pad. Produced decontamination water was disposed of by pumping from the temporary decon padinto the shallow tray air stripping unit at the MWDS Treatment Plant. Groundwater produced at the well sitewas initially contained in the plastic lined roll off boxes. Following initial de-sedimentation, the drillertransferred the produced water into temporary holding tanks staged at the drill site or collected the water bya vacuum truck and transported to the MWDS Treatment Plant.

In February 2001 the Shiawassee District MDEQ office determined that the produced water from the wellswas a "liquid industrial waste" and therefore required a licensed hauler. A Letter of Warning wassubsequently issued on March 14, 2001 from that office of MDEQ. SHARP responded to the Letter ofWarning on April 1 1, 2001, and the procedures for transporting the produced water were changed for thebalance of the project. The driller contracted the services of Key Energy Services, Inc., a licensed industrialwaste hauler (ID# MIR0000230002), to transport the produced water from the drilling locations to MWDS.At MWDS a 20,000-gaIlon frac tank served as temporary storage for produced water. The water from thefrac tank was then transferred into the shallow tray air stripper at the MWDS Treatment Plant.

A second approach was also used to dispose of produced water. The City of Lansing's sanitary sewer wasused at various dril l ing locations, depending on the proximity of a sanitary sewer drain. This was apermitted procedure and SHARP obtained permits for each location where this method was used.

1.6 Surface Completion

The drilling contractor completed all of the Saginaw Aquifer monitoring wells with flush mounted, surfaceprotectors to the specification in the approved Work Plan. The upper part of the exposed, 8-inch steelsurface casing was cut off to a level slightly below grade. The wells were finished with a 9-inch x 12-inchsteel curb box centered over the top of the pipe and constructed a 2-foot x 2-foot x 2.5-foot concrete padcentered on the steel curb box to finish the area around the monitoring well. The concrete pad was finishedslightly elevated with respect to the surrounding land surface to encourage precipitation drainage away fromthe well at those locations where it was possible.

Sharp attd Associates, ltn. 1 .** "^

1.7 Well Survey

A licensed surveyor was contracted to determine the horizontal coordinates of the well and to determine thevertical elevation of a permanent reference point located on the top of the 8-inch well casing. This referenceelevation was surveyed to an accuracy of 0.01 foot and used as the referenced measuring point for allsuccessive water level measurements. The x, y, z coordinates are consistent with that system previouslyestablished for the existing CERCLA monitoring well network. The following table summarizes the results.

SECTION 2.0 SAGINAW AQUIFER DATA COLLECTION

2.1 Initial Gamma Ray and Calipcr Logging

The borehole was logged with a portable three-arm caliper tool prior to vertical testing and sampling. Thepurpose of running the caliper tool was to determine possible borehole diameter variation that could causeproblems with seating the packers at the chosen intervals. This in i t i a l caliper information was verified with alater caliper run during the geophysical logging in each borehole (FCO #2). The latter caliper trace wasrecorded and is displayed on the geophysical portion of the composite logs (Figures 2-9) and also on thegeophysical logs making up the cross-sections.

USGS personnel also ran a gamma ray tool in each borehole prior to the start of sampling procedures. Thisin i t i a l gamma ray log was used in conjunction wi th the field lithology record to determine the appropriateintervals for hydraulic testing in the open bore.

2.2 Hydraulic Interval Testing

Field personnel conducted the hydraulic interval testing using an inflatable, double packer assembly, aGrundfos 3-inch submersible pump capable of a maximum pumping rate of 31 gpm, and twodatalogger/transducers. After this packer assembly became stuck while attempting to test the lower shaleinterval in MW-88, Layne configured a separate packer assembly to continue the work. This packerassembly was only configured to conduct the vertical analytical sampling and was configured so that thedistance between the packers was 20 feet. The Work Plan was modified (FCO #5) to allow alternativepumping rates and analyses to be used in the shale interval so that the risk of getting the packer assemblystuck again was reduced. The primary packer assembly was removed from MW-88 and was repaired. Therepaired assembly was used for the hydraulic conductivity testing (and later the vertical analytical samplingas well) and was configured according to the specification in the approved Work Plan; however severaltransducers were used prior to the final configuration, and the distance between packers in the finalassembly was 23 feet. The packers were configured to inflate simultaneously.

The lower transducer provided data qualifying the proper setting of the lower packer. A water levelindicator tape was used to test for drawdown above the upper packer. The profile sampler assembly waslowered into the open borehole after the driller cleared the borehole of cuttings and removed turbid water tothe extent practical. The decontaminated packer assembly was run to the bottom of each borehole and wasstopped twice on the way down to check the transducer calibration. The first test interval was nominally377-400 feet. The assembly was pulled up after the testing was complete and set at progressive 23-foot testintervals. Field and agency personnel jointly modified the depths of these intervals based upon theinterpretation of a preliminary gamma ray log ran by USGS personnel.

The tightness of the packer seats was verified by checking for pressure leak-off at the nitrogen tank pressuregages and by comparing the water levels above, between, and below the packers using the pressuretransducers and a water level tape. Following the verification of the packer seats, each discreet test intervalin the sandstone was pumped for a minimum of 30 minutes while the datalogger was recording. Thepumping rate for the testing in the sandstone was set to the maximum that the pump would produce from theinterval and was held constant at that rate during the test. Testing in the shale intervals followed proceduresapproved in the FCO.

Sharp a/xJ Associates, Inc. •* •»~ *

The recording rate was reset for each interval test. The rate was always set to logarithmic with a maximumof 1-minute intervals. At the end of the 30-minute cycle, the pump was shut off and recovery was loggedusing the central datalogger/transducer. After water levels recovered to at least 95% of the pre-pumpinglevels the recovery portion of the test was stopped

Standard methods were used for the data analysis of the hydraulic testing. The Theis analysis (1946) wasappropriate for those intervals tested at a constant rate for 30 minutes. However, the Bouwer & Rice (1976)method of analysis was used for those tests performed in the shale units using the alternative procedure. Thedata analyses of the packer tests are summarized as a relative transmissivity (%) chart on Figures 2 through9 of this report. Thorough analyses are contained in Appendix C. The data analyses provide an empiricalindication of transmissivity that was used in conjunction with an open hole step test and a recover} test.

2.3 Saginavv Aquifer Vertical Profiling

Field personnel conducted the vertical profiling using an inflatable, double packer assembly and a GrundfosRedi-Flo 2 variable-speed, submersible pump capable of a m i n i m u m pumping rate of <1 liter/minute. Thesampling procedures followed the approved Work Plan.

The initial packer assembly became stuck while attempting to test the lower shale interval in MW-88, and sodr i l l ing personnel configured a separate packer assembly to continue the work. This packer assembly wasonly configured to conduct the vertical analytical sampling, and was configured so that the distance betweenthe packers was 20 feet. The initial packer assembly was removed from MW-88 and was repaired. Therepaired assembly was used for the hydraulic conductivity testing (and later the vertical analytical samplingas well) and was configured according to the specification in the approved Work Plan. The distancebetween packers in this assembly was 23 feet.

The Grundfos Redi-Flo 2 variable speed submersible pump was used within the 2-inch discharge pipe topurge and sample the packed off interval. The purge rate was the maximum capable from the pump, and wasgenerally between 2 Vz gpm and 4 gpm. The effectiveness of the purging process was monitored at thesurface through the use of a multi-parameter flow through cell connected to a slipstream line of the maindischarge hose. This instrument measures water quality values of: pH, temperature, specific conductivityand ORP (redox potential). Stabilization of the field parameters to within + 10% during the hydraulic testwas used to indicate that representative groundwater samples could be collected. The pump rate waslowered to < 1 liter/min. for the collection of samples for chemical analysis.

The water samples collected as equipment rinse samples and from each of the vertically profiled intervalswere analyzed for VOCs, ammonia, fluoride and potassium. The analytical program is summarized on thefollowing table.

Following sample collection, field personnel shut off the pump, deflated the packers, and raised the packerassembly to test the next overlying sample interval . The same pumping, sampling and monitoringprocedures were followed through each successive profile interval. This ascending succession of sampleintervals continued un t i l the last 20-foot interval below the base of the surface casing was collected.

2.4 Geophysical and Down Hole Acoustic Logging

COLOG, Inc. was contracted to run a suite of gamma-ray and resistivity logs within each borehole. Theselogs are the same as those that had been previously run in the majority of the MWDS Saginaw wells, theinactive MWDS Plant Well, and several of the BW&L production wells. COLOG personnel ran the gamma-ray log throughout the total depth of each well, while the resistivity log was limited to only the open-holesection of each well. A high-resolution video log (Borehole Image Processing System, or BIPS) was alsorun with the suite of geophysical logs on the first four wells drilled (MW-87, MW-88, MW-91, and MW-92). The purpose of running the high-resolution video was to determine if there was a possibility thatfracturing in the Saginaw Formation could influence groundwater flow. Based upon the complete lack offracturing seen in those video logs of the first four wells, an FCO was approved that dropped the video logfrom the second half of the geophysical program (FCO #8).

The gamma-ray and resistivity logs were used to assist with stratigraphic correlation within the bedrockinterval, to help determine stratigraphic thicknesses, and to help identify variations in the fluid/groundwaterchemistry. The logs are displayed on Figures 2 through 9 of this report, and are also used in cross sectionsD-D' and E-E' of this report and discussed in Section 2.7 below.

2.5 Open Hole Aquifer Tests

Once the vertical testing was complete, the driller lowered a pump /discharge pipe assembly into the wellfor a step test. The pump was set below the water table within the steel casing section of the well. The workplan specified that the pump would be run at four different pumping rates for 30-minute time intervals,while the drawdown was logged with the transducer and manual measurements. FCO #6 documented achange to increase the time intervals to 60 minutes per step. Layne set the pumping rate for the first step to25 gpm and incremented successive steps by 25 gpm (i.e. 25, 50, 75 and 100 gpm). Thetransducer/datalogger was stepped so that each test interval was logged logarithmically. Once the fourth stepwas complete, field personnel shut the pump off, stepped the datalogger, and logged the water levelrecovery. The water level recovery was logged until water levels in the well reached at least 95% of the pre-pumping, static levels.

The transmissivity of the Saginaw Aquifer was greater than expected at MW-87 and there was insufficientdrawdown during the test for a valid analysis. Consequently FCO #9 was approved to allow a constant rateaquifer test to be performed. The pump was run at 157 gpm for a period of 4 '/2 hours.

The analysis of the step test data was performed using the Birsoy-Summers (1980) method and also theEden-Hazel (1973) method. The recovery portion of the test was analyzed using the Theis (1946) residualrecovery method as a back-check against the other methods. The analyses are contained in Appendix II.

2.6 Composite Summary Logs of Individual Well Results

In conjunction w i t h the instal la t ion of these monitor wells, mul t ip le lines of additional lithologic.chemical and hydraul ic data were also collected. Lithologic data included the stratigraphic collectionand description of wel l cuttings and the collection of a suite of mechanical and geophysical logs (gammaray, 16" and 64" res i s t iv i ty logs and caliper logs).

The data obtained from the 2000-2001 field investigations has enhanced the understanding of the UpperSaginaw Sandstone. High resolution resistivity logs and vertical profile flow testing have identified apersistent series of interbedded sandstones, siltstones and shales which in some areas have notably highervalues of hydraulic conductivity than do the overlying "upper sandstone member" or the underlying"middle sandstone member". Figures 2 through 9 illustrate the geology and the geophysical and verticalflow characteristics associated with this "interbedded series". The significance of this high permeabilityinterbedded series to the transport and distribution of the MWDS contaminants is probably best seen inthe records of MW-87 (Figure 2). This display shows not only the variability of horizontal flow zones,but also the correlation of contaminant concentrations to these areas of higher permeability. The abilityto physically and chemically demonstrate this correlation, serves to support the hypotheses andinterpretations presented in previous Saginaw Investigation reports.

2.7 Geologic Cross Sections

The additional stratigraphic and structural relationships of the Pennsylvanian aged bedrock section that wereobtained from the 2000-2001 drilling program are presented on two cross-sections. These sections, Cross-Sections D-D' and E-E' are referenced as Figures 10 and 11, and are included in pockets attached to the endof this report. Note that cross-sections A-A', B-B', and C-C' were presented in the Final Report "TheResults of the Saginaw Aquifer Investigation at the Motor Wheel Disposal Site, March 1998". In addition tothe new cross sections, the Saginaw stratigraphic and hydrologic information obtained during this recentdri l l ing program has been incorporated into the older cross-sections, and has been provided to WaterlooHydrogeologic, Inc. (WHI) to incorporate into their hydrogeologic model of the Saginaw Aquifer.

The interpretations shown on the cross-sections D-D' and E-E' reflect not only the data collected fromprior field investigations, but also dynamic data that were collected from the 2000-2001 field program.The net effect of these multiple lines of data on the characterization of the Saginaw Aquifer is that theyhave permitted the Saginaw to be subdivided into five (5) stratigraphic/hydrologic intervals that can becorrelated throughout the MWDS area of study. The previously published cross-sections in the 1996 and1997 Saginaw reports had recognized the stratigraphic character of the erosionally truncated upper blackshale member and three persistent stratigraphic sub-members within the overall Saginaw SandstoneFormation. In SHARP'S 1996 report, the sub-members within the Saginaw Formation were informallylabeled as the Upper Saginaw Sand, the Middle Saginaw Shale Uni t and the Lower Saginaw Sand.

Significant to the 1996 Saginaw investigation was the discovery that the ammonia and limited vinylchloride contamination were vertically and horizontally asymmetrical in their distributions andconcentrations. This interpretation was made as the contaminants were dominantly present within theupper part of the Saginaw Aquifer near the southern/upgradient part of the study area (MW-65 and MW-66), and then became less concentrated and more vertically disseminated in the downgradient(northwesterly) direction (MW-67 and MW-68). The findings of the 1997 Saginaw investigative field

Sharp aiuJ ASMM.~KJI?\. lm. *\ A~

program were consistent wi th these interpretat ions. The cross-sections published in SHARP'S 1997report were expanded to include monitor wel ls MW-75 and MW-78. and extraction wel ls SEW-1 andSEW-2. These updated cross-sections show repeatahle vertical succession of the stratigraphic members,and the i r lateral persistence through the area.

The new cross-sections D-D' and E-E' that have been produced for th is report have cont inued to bu i ld onthe previously published sections. The geologic depiction of the strat igraphic and structural relationshipsbetween the glacial sediments and the Penpsylvanian bedrock is consistent w i th the previously publishedinterpretations. As the most recent field data have been incorporated into the new cross-sections, and theprevious cross-sections and maps re-examined, the fo l lowing updated interpretation of the area has beendeveloped. This area displays a complex series of glacial and glacio-f luvial sediments settingunconformably on a d i f fe ren t ia l ly eroded northwesterly dipping bedrock surface. The uppermost bedrocklithology in the area is the "upper black shale member". This black shale member is present in thenorthern part of the area, but has been removed by glacial erosion in the central and southern part of thefield area. The recent hydraulic testing performed in MW-94 confirmed the previously reported ENSRhydraulic test data that showed the upper black shale member to be an effective barrier to downwardmigration of waters from the glacial sediments into bedrock. In areas where the upper black shale isabsent, glacial sediments set upon the eroded upper surface of the Saginaw Sandstone Formation.

2.8 Vertical Gradient

The vertical gradient information was derived from the transducers and water level tape measurementstaken before and after the packers were inflated. The vertical gradient wi th in the well bore wasconsistently downward in all of the new wells with the exception of MW-94. The proximity to pumpingwells SEW-1 and SEW-2 is likely why the vertical gradient is so low in this well. The data and chartsare contained in Appendix F of this report.

SECTION 3.0___________________________________________CONCLUSIONS

3.1 Conclusions

This investigation has produced a greater understanding of the interrelationships between the geology,groundwater aquifer flows, and the movement of groundwater contaminants from the MWDS. TheRemedial Investigation investigated the groundwater quali ty and flow conditions w i t h i n the SaginawAquifer , as they relate to both the historic activi t ies of the MWDS and the City of Lansing's BW&l.North Well Field.

The geological model (created from borings, well logs and geophysical logging), the hydrologicgroundwater model, and the contaminant data are internal ly consistent. The hydrogeologic model wasre lined based on the geologic structural model and field hydraul ic testing. The flow of contaminants inthe groundwater model and location of the drop in area from the Glacial Aquifer to the Saginaw Aquiferremains consistent w i t h the contaminant plumes constructed based on groundwater analytical data.Having consistency of the data from 3 different approaches adds a high degree of confidence inunderstanding the subsurface flow mechanics.

This investigation has refined:• The groundwater flow pattern of the Saginaw Aquifer;• The interrelationship that exists between the Glacial Aquifer and the Saginaw Aquifer;• The horizontal and vertical extent of contamination; and• The groundwater flow in the Saginaw Aquifer is Matrix flow and is not impacted to a significant

degree by fracturing.

3.2 SAGINAW AQUIFER INFORMATION INPUT INTO THE GROUNDWATER MODEL

The model is being updated from previous simulations with refinements to the hydraulic parameters ofthe aquifers that are based upon data gathered from the newly installed wells. The analytical results willalso be used for refinement of the current contaminant mass and future simulations of contaminant flow.

CAUSE/EFFECT FOR FIELD CHANGE: The initial caliper logs for MW-87, 88, 91 and 92 did not

match initial calibration (due to not being able to adjust the potentiometer span on the instrument to

match the ring size). Rather than scaling the instrument readings to adjust for the span, caliper logs will

f '^! be re-run in these wells when the full suite of geophysical logs are run.

MWDS FIELD CHANGE FORMDRAFT CHANGE # 5SHARP JOB# 9113-18_________JOB NAME: MWDS SAGINAW INVESTIGATION


SUMMARY OF CHANGE: The original work plan included hydraulic testing through the

entire Saginaw interval without specifying any variations for shale and sandstone intervals. The

change to a less stressful water (slug) out test when testing shaly sections and an accompanying

change in the packer inflation pressure will minimize the risk of further problems with the packer

assembly._________________________________________________

CAUSE/EFFECT FOR FIELD CHANGE There is some evidence from examining the

damaged packer assembly that the previous attempt to perform a packer test in a shale sectionusing the 3-inch Grundfos pump contributed to the packers getting stuck in the well. The

proposed procedural changes (see attached) will minimize further risk while interval testing, but

still allowing for hydraulic data acquisition and analysis from the shaley sections in the Saginaw.

DATE: 3/9/01_____________SUBMITTED BY: Todd Struttmann,_______

SUMMARY OF CHANGE; The step test originally proposed for an open borehole test in each

of the wells consisted of a series of four pumping steps in '/2 -hour increments, followed by a

recovery period. The proposed change is to lengthen the duration of each step to 1 hour in order

to provide superior data. The recovery period between step intervals will remain unchanged as

will the step-pumping rates. The pumping rate of the first step will be set to 25 gpm and increased

by 25 gpm for each step.____________________________________CAUSE/EFFECT FOR FIELD CHANGE; The step tests were proposed to be limited in length

of pumping time because of the problems of storing and handling large quantities of water in sub-

freezing temperatures. These conditions have been mitigated due to the fact that dischargepermits have been issued by the City of Lansing for the use of the sanitary sewers, and by

performing the tests in March and April rather than in December and January.

Procedure changes for Field Change Orders #5

Hydraulic testing in the Saginaw Shale

The following change to the RD-WP will be conducted in order to derive meaningfultransmissivity data from the shale and shaley sections of the Saginaw aquifer while limiting therisk of further equipment losses. Please note that these changes are only proposed for intervaltesting in the shale and shaley intervals of the Saginaw and packer testing procedures forremainder of the Saginaw aquifer will remain unchanged.

The packers should only be inflated to the calculated pressure that is necessary for a seal theinterval to be tested, rather than greater than the calculated amount. The standard to be used is 15psi greater than the calculated hydrostatic pressure on the packer. This technique has been provensufficient to provide a seal by USGS. Following inflation, the transducers will be checked toverify that a seal has been made.

There is a check valve in the 3-inch pump assembly which precludes the use of a slug tohydraulically test packed off intervals in the wells. The check valve is necessary to eliminateinstantaneous flow back into the well when the pump is shut off during packer testing in thesandstone. If this flow were to occur it would invalidate the recovery portion of the test.

Therefore, the following procedure is proposed.

1. Lower the Grundfos Redi-flow pump into the 2-inch discharge rods connecting thepacker assembly.

2. Set the transducers to record water levels on a logarithmic scale.3. Calculate the packer inflation pressure necessary to overcome hydrostatic pressure

plus 15 psi. Inflate the packers.4. Verify that the packers are sealed based on measurements from the transducers.5. Turn on the Grundfos Redi-flo pump to draw the water level down to an elevation

that is sufficient to create a pressure drop of 20 feet as read on the transducer betweenthe packers.

6. Record the change in pressure in the transducer between the packers.1. As soon as 20 feet of pressure drop (drawdown) has been achieved at the transducer,

turn off the Grundfos Redi-flow pump8. Continue recording water level measurements during recovery (in the middle and

lower transducers and hand measurements for above the transducers) for a period of30 minutes or until 95% recovery is observed, whichever is the shorter time interval.

9. Evaluate the recovery vs. time to determine relative hydraulic properties. Using thismethodology will allow the use of a slug-out analysis of the data.

9ll3\FCO03.doc 6 5/31/01


Open Borehole Step testing

SHARP proposes to change the duration of each step test from a series of four '/z-hour steps to aseries of four 1-hour steps. The pumping rate of the first step will be set to 25 gpm and increasedby 25 gpm for each successive step (i.e., 25 gpm, 50 gpm, 75 gpm and 100 gpm) as per theoriginal specification. The rate of 100 gpm approximates the maximum rate available from apump that will fit into the existing nominal borehole diameter (4 5/8 inches) of these monitoringwells. The step tests will still be followed by a recovery period sufficient to log the recovery ofwater levels to at least 95% of the pre-pumping, static conditions.

The hole was then drilled to 403 feet bgs.The problem encountered was that there was caving/sloughing in the hole creating a recurrentbridge at 97' bgs. The proposed change is to ream the hole with a 7 7/8" bit to -115' bgs andsetting an intermediate 6 inch casing string to isolate the caving/sloughing area. Details areprovided below.___________________________________________CAUSE/EFFECT FOR FIELD CHANGE: The instability of the upper Saginaw Formation

Well completion ofMW-93

The following change to the RD-WP will be conducted in order to address the unstable formationencountered in MW-93 between 91 feet and -100 feet.

The following procedure will be used.

1. Ream the hole with a 7 7/8-inch rock bit from 91 feet to ~115 feet bgs.2. Set a mechanical grout plug in the existing 4 5/8"rock borehole.3. Add a grout shoe to the bottom of the 7 7/8" hole.4. Lower the 6-inch steel casing to ~2-3 foot above the grout shoe.5. Lower a downhole pump into the 6-inch casing.6. Record static water level.7. Purge the well at a flow rate sufficient to provide at least 1 foot of drawdown but no

more than 5 foot of drawdown during pumping. (The objective is to sufficientlystress the aquifer, but not cause additional borehole damage).

8. Record the field water quality parameters as detailed in the existing RD-WP.Purging will continue until at least 3 wellbore volumes have been purged and theparameters have become stabilized. (Note with a water level of 61' bgs and abottom at 115' bgs, -430 gallons will need to be purged to meet the 3 well volumerequirement). Based on the specific capacities from the higher permeability sectionsin MW-87 and MW-90, it is anticipated that a pump capable of 20-50 gpm will besufficient for this higher rate purging. The actual rate will be determined in the field.

9. Consistent with the RD-WP, sampling will be conducted at a purge rate of <lL/min.There are two ways to accomplish this: 1. reduce the flow rate of the existing pumpto meet the IL/min requirement; or 2). Set in the 6-inch casing a Redi-Flow n pumpand sample same at a rate of <lL/min. In this case, the Redi-Flow II pump intake hasto be below the intake of the existing pump.

10. Add a lift of sand on top of the grout plug.11. Lower the 6-inch casing to seat at base of 7 7/8" borehole.12. Reverse pressure grout 6-inch casing into position. Record the amount of grout

added.13. Allow grout to set 24 hours.14. Pressure test 6-inch casing grout.15. Drill out 6-inch casing with 4 5/8 inch rock bit to original TD of 403 feet bgs.16. Circulate and clean out in preparation for vertical profiling.

Attachments:• FCO#8 - Elimination of BIPS logging tool for the last 4 monitoring wells (MW-89, MW-

90, MW-93, MW-94)








SHARP JQB# 9113-18_________JOB NAME: MWDS SAGINAW INVESTIGATIONDATE: 4/19/01 (Discussed, approved & implemented)BY: Todd Struttmann

SUMMARY OF CHANGE: The original work plan included a full suite of downhole logging

including Borehole Image Processing System (BIPS). The purpose of the BIPS tool was to

resolve whether the flow in the Saginaw aquifer was dominated by fracture flow or equivalent

porous media. This high resolution tool was run on the first 4 monitoring wells (MW-87, MW-

88, MW-91 and MW-92). Due to the lack of fractures identified in the first 4 wells logged, the

remaining 4 wells (MW-89. MW-90. MW-93 and MW-94) will not be logged with the BIPS tool.

CAUSE/EFFECT FOR FIELD CHANGE:. Goodyear proposed that the BIPS be dropped from

the last 4 monitoring wells due to the BIPS tool having fulfilled its objective of resolving fracture

flow vs equivalent porous media. USGS described the results as "underwelming" due to lack of

fractures (that would control flow) in all 4 wells and agreed dropping the log for the last 4 wells.Although representatives of MDEQ thought that there may be of some benefit in the information

gained by running the tool, the resolution was to drop the BIPS tool from the suite. Othercomplimentary data collection in the drilling program (i.e., gamma logs, vertical chemical

profiling, vertical hydraulic profiling, resistivity logs and lithologic logs) will still allow for a

thorough evaluation of the aquifer at each well bore.REFERENCE SECTION IN THE FINAL REVISED WORK PLAN:Section 3.3 ______________________________________________

SHARP JOB# 9113-18_________JOB NAME: MWDS SAGINAW INVESTIGATIONDATE: 5/7/01 (Discussed, Implementation pending)BY: Todd Struttmann

SUMMARY OF CHANGE: The original work plan included a step test of each monitoring well

to determine the transmissivity of the entire well bore. This was conducted in a series of 4, 1-

hour steps at 25, 50, 75 and 100 gpm. For well MW-87, the highest step was at 85 gpm resulting

in ~1.2 feet of drawdown. The existing transducer has an accuracy of+0.29 feet of head (+0.05%

on 250 psi full scale). The combination of little head change and limited accuracy of the

transducer, cause the results of the March 19, 2001 test to be unusable. A follow-up test on thiswell is proposed with a higher pumping rate and a more accurate transducer for water level

measurements. The transducer to be used is an In Situ Troll with an accuracy of +0.03 feet

(+0.05% on 30 psi full scale).

The re-test will be conducted as a constant rate test at a nominal 150 gpm rate for 4+ hours. Two

frac tanks (21,000 gallons each) will be setup together to contain the aquifer test water.Concurrent with running the test, water will be metered and discharged to the sanitary sewer (~35

gpm maximum). The test will be run until the tanks are full. Assuming some quantity draining

from the tank while filling the tanks, the test will be run ~5 hours. As before, water levels will be

recorded until 95% of the recovery is reached.

CAUSE/EFFECT FOR FIELD CHANGE: The field change is needed because the existing

data set for the step test from MW-87 is not sufficient to quantify a value of transmissivity for the

wellbore.REFERENCE SECTION IN THE FINAL REVISED WORK PLAN:Section 3.4
