Summary Of field activities: Two separate sampling events were conducted byMontgomery Watson, the PRP Contractor, during this reporting period. On October 31,

1996, surface soil/sediment sampling was conducted along the USEPA-approvedPerimeter Groundwater Containment System (PGCS) extraction trench alignment. From

November 4, 1996 through November 7, 1996, quarterly groundwater sampling was

conducted at the site.

Surface Soil/Sediment SamplingThe objective of the surface soil/sediment sampling was to identify the

contaminant characteristics of spoils which would be generated during the PGCS

extraction trench excavation. The soil/sediment sampling was conducted in accordance

with the October 30, 1996 Specific Operating Procedure (SOP). A total of 13

1

soil/sediment samples, ACS-PGCS-01 through ACS-PGCS-13, were collected along theUSEPA-approved PGCS extraction trench alignment. The first and last soil/sedimentsamples along the trench alignment were located approximately 140 feet and 1,100 feet,respectively, from the north end of the trench alignment. Samples were not collectedfrom upland areas, away from wetland soils and vegetation. In general, the samplelocations were 50 to 100 feet apart with two exceptions. The distance between sample

locations ACS-PGCS-01 and ACS-PGCS-02, and sample locations ACS-PGCS-05 and

ACS-PGCS-06 were 150 feet and 110 feet, respectively.

At each location, soil/sediment sample was collected to represent the upper 24

inches of the soil profile. The hand auger was pushed to the desired depth into thesoils/sediments. Occasionally, it required two or more excursions of the sampling device

to fulfill the sample volume requirements. After retrieval, the sample was transferred intoa stainless steel bowl using a stainless steel spatula. The soils/sediments retrieved from

the 24-inch column were 'composited' in the stainless steel bowl prior to filling two 4-ozsample containers. One container was marked for field screening level TotalPolychlorinated Biphenyls (PCBs) analysis, whereas the other sample container wasmarked for possible confirmatory laboratory analysis. For field screening level Total

PCBs, the Omnicron RAPID Assay Method, previously approved by the USEPA, was

used. All samples were shipped to Madison, Wisconsin office of Montgomery Watson

under the approved chain-of-custody protocols.

Prior to sample collection at each location, decontamination of the sampling

equipment was conducted in accordance with the SOP.Copy of BVSPC field notes and photographs of field sampling activities are

attached.

Groundwater SamplingFirst round of quarterly groundwater sampling was conducted during the week of

November 4, 1996. Prior to beginning sampling, a round of water level measurements

were taken from all existing monitoring wells/staff gauges/piezometers with the following

exceptions:Location Remarks

Monitoring Well M-3D Field Personnel could not get the well open

Staff Gauge SG-1 DryStaff Gauge SG-4 DryStaff Gauge SG-6 High water was encountered at this location. Field

Personnel did not have hip-waders available on-site

Staff Gauge SG-11 DryPiezometer P-2 Field Personnel could not locate this piezometerPiezometer P-12 Free Product was encountered at this locationPiezometer P-29 Free Product was encountered at this location

Piezometer P-30 Free Product was encountered at this location

Water level measurements were taken by three to four field teams at a time.

BVSPC personnel remained with one field team and obtained a copy of the complete

set of field data from Montgomery Watson (attached). Water level measurements at the

Griffith Landfill wells were taken on November 6, 1996 in the presence of City ofGriffith's Environmental Consultant.

Groundwater sampling was conducted in accordance with the revised SOP forGroundwater Monitoring Well Sampling dated March 8, 1996. The October 30, 1996letter to the respondents also provided an SOP clarification which permitted respondents

to use deionized water for decontamination purposes and for field blank preparation.The sampling locations and analyses for upper aquifer wells were approved by the

USEPA in a letter to the respondents dated October 30, 1996. The sampling locations

and analyses for lower aquifer wells were approved by the USEPA in a letter to therespondents dated October 11, 1996. All samples, except for MW-7 and MW-21, were

to be analyzed for full-scan analytes (TCL/TAL). Samples from wells MW-7 and MW-21were to be analyzed only for full-scan organics (TCL).

Groundwater samples were collected from the following wells: upper aquifer wellsMW-6, MW-11, MW-12, MW-13, MW-14, MW-15, MW-18, and MW-19; and loweraquifer wells MW-7, MW-8, MW-9, MW-10C, MW-21, MW-22, MW-23, MW-24, MW-50(new well near PW02), and MW-51 (new well near MW-10). The upper aquifer wells M-

1S, M-2S, M-4S and the lower aquifer well M-4D are located within the Griffith Landfillarea and are owned and operated by the City of Griffith. These wells could not be

sampled due to access restrictions for sampling purposes.Groundwater purging and sampling was conducted using a low-flow Grundfos

submersible pump. The pumping rate was maintained at approximately 300 ml/minute.

Field parameters such as pH, specific conductivity, temperature, and turbidity readingswere measured during purging. Sampling was initiated when the field parameters

stabilized for three consecutive readings within 10 percent of the previous readings.Sample handling and chain-of-custody procedures were followed in accordance with theSOP.

BVSPC split a total of eight (8) samples with Montgomery Watson for followingwell locations: upper aquifer wells MW-12, MW-13 and MW-19; and lower aquifer wellsMW-8, MW-9, MW-10C, MW-50 and MW-51. BVSPC also collected a field duplicateat MW-13, an equipment blank sample, and a total of six (6) trip blanks. BVSPCsubmitted all samples for full-scan organic analyses to the CLP laboratory, RollinsEnvironmental in Ann Arbor, Michigan. BVSPC submitted all samples for full-scaninorganic analyses to the Central Regional Laboratory in Chicago, Illinois. The splitsample locations were verbally approved by the USEPA WAM Sheri Bianchin. Thesample handling and chain-of-custody procedures were followed in accordance with theMini-Quality Assurance Project Plan, Revision 2, March 12, 1996, prepared by BVSPC.Copy of BVSPC field notes and photographs of field sampling activities are attached.

Problems Encountered/Corrective Actions: In general, both sampling eventsproceeded without much problem. There was some confusion regarding field marking ofthe well MW-51, the new well installed near MW-10. The well was marked incorrectlyas MW-50. BVSPC reminded Montgomery Watson to correct the marking as soon aspossible.

As mentioned above, the four landfill wells could not be sampled due to accessrestrictions for sampling purposes. The Respondents are currently in the process ofobtaining access to these wells.

Future Work Schedule: Phase II wetland sampling and excavation for PGCS extractiontrench is scheduled to begin during the week of November 18, 1996. It is anticipated thatthe four landfill wells will be sampled in December 1996. BVSPC will collect splitsamples on two of these wells, MW-1S and MW-4S, as indicated earlier by the WAM.In accordance with the USEPA letter dated October 11, 1996, the Respondents willinstall two new well nests within the lower aquifer. One well nest will be installedbetween existing wells MW-8 and MW-10, and the other well nest will be installedbetween MW-24 and MW-10. The installation and sampling of these wells is expectedto be completed in December 1996.
