RE: Comparison of Soil Split Sample Analytical Results at Neal's Landfill

Dear Ms. Alke:

Enclosed for your review is the Tetra Tech report on the analytical results from the split samplestaken during the boring program at Neal's Landfill. The split sample results are consistent withthe analysis by your consultant, PSARA. Based upon the comparison of the sample results,reconciliation of the laboratory analysis is not required. If you have any questions on this report,feel free to contact me at your convenience.

Sincerely, ' -

Subject: Comparison of Soil Split Sample Analytical ResultsNeal's Landfill Site, Bloomington, IndianaContract No. 68-W7-0003, Work Assignment No. 020-RSBD-0539

Dear Mr. Alcamo:

In accordance with the U.S. Environmental Protection Agency (EPA)-approved work plan for the above-referenced work assignment, Tetra Tech EM Inc. (Tetra Tech) conducted field oversight of remedialinvestigation/feasibility study (RI/FS) activities and obtained 10 soil split samples and one duplicate soilsplit sample from PSARA Technologies, Inc. (PSARA), during drilling and sampling of soil boringsCBS-SB1 through CBS-SB13. PSARA completed these borings at the Neal's Landfill site for ColumbiaBroadcasting System (CBS), the responsible party for the site. The sampling activities took place onMarch 30 and 31,1998.

Tetra Tech obtained soil split samples from borings CBS-SB 1 at 5 to 8 feet below ground surface (bgs),CBS-SB2 at 10 to 13 feet bgs, CBS-SB3 at 3 to 6 feet bgs, CBS-PZ5 at 10 to 12.5 feet bgs, CBS-SB6 at5 to 8.5 feet bgs, CBS-SB8 at 2.2 to 3.5 feet bgs, CBS-SB9 at 8 to 11 feet bgs, CBS-SB 10 at 7 to9 feet bgs, CBS-PZ12 at 15 to 16 feet bgs, and CBS-SB 13 at 15 to 16 feet bgs. The duplicate soil splitsample was obtained from boring CBS-SB 13. The soil samples consisted primarily of waste and clay fillsimilar to that encountered during Tetra Tech's RI/FS field activities under Work AssignmentNo. 022-RICO-0539.

Tetra Tech's soil split samples were analyzed by DataChem Laboratories for polychlorinated biphenyls(PCB) using EPA SW-846 Method 8082. PSARA's soil samples were analyzed by HeritageLaboratories. Analytical data indicate that PCBs were detected in six of the split samples, including theduplicate split sample, obtained by Tetra Tech. These data and the corresponding analytical dataobtained by PSARA are presented in Table 1. Analytical laboratory data sheets for Tetra Tech's soilsplit samples are enclosed.

As shown in Table 1, the analytical data sets for PSARA's soil samples and Tetra Tech's soil splitsamples are within one order of magnitude. This degree of data variability is to be expected given theheterogeneous nature of the intermixed zones of waste and clay fill sampled during drilling. Althoughsamples were thoroughly composited in the field before split sample collection, the possibility exists thatareas of high and low contamination were present within the sample volume collected for analysis.

Mr. Torn AlcamoMay 13, 1998PageS

A similar degree of data variability was observed for soil samples, duplicate samples, and reanalyzedsamples collected by Tetra Tech during drilling of 77 borings at the site from March 23 through 28,1998. These activities were performed as part of the RI/FS drilling and sampling conducted by TetraTech for EPA. Based on RI/FS sample analytical data, PSARA's and Tetra Tech's soil split sampleanalytical data are in reasonable agreement.

Case Narrative

Method: 8082 Client: TetraTechAnalysis: PCB's in Soil Account: 8001Preparation SOP No: SW846 8082 Matrix: SoilAnalysis SOP No: SW846 8082 DCL Set ID: 98E-0153-01

General Set Information: There are eleven field samples in this lot. The samples were analyzedfor Aroclors 1016, 1221, 1232, 1242, 1248, 1254 and 1260.

Method Summary: A representative 3 g (±0.1 g) portion of soil is extracted into 10 mL of 1:1hexane/acetone using an ultrasonic extraction apparatus. A portion of the extract is diluted100 X for analysis. Analysis is by electron capture gas chromatography, with the followingconditions:

Injection ports: Split/splitless in split less mode, temperature250 °C

Primary column: DB-608, 30 m x 0.53 mm, with 0.84 urn film,head pressure 4 psi

Confirmation column: DB-1701, 30 m x 0.53 mm, with 1.0 jim film,head pressure 4 psi

Detectors: Electron capture, temperature 300 °C

Sample Preparation: AH samples were prepared in accordance with published procedures.

Holding Times: Holding time requirements were met for both sample preparation and analysis.

Dilutions: All field samples were pre-diluted 100 X prior to analysis. No sample required furtherdilution. • 003

M:\wordperf\pcb0402 Page 1 of 3

Meithod and Sample QC data:

Method Blank: No method analyte was detected in the method blank at levels above lowerreporting limits.

Surrogates: Surrogate recoveries were within established limits for all field samples, blanksand control samples.

Laboratory Control Sample: All recoveries were within established limits.

Matrix Spike and Matrix Spike Duplicate: Matrix Spike and Matrix Spike Duplicate sampleswere prepared from field sample CBS-SB3-36. Aroclor 1242 was present in theunspiked sample at a level far above the spike. In this case, the MS/MSD pair servemore nearly as matrix duplicate samples. It should be noted that there is considerabledisparity between the parent sample and the two spiked samples. This is attributed tonon-homogeneity of the sample matrix.

Instrument QC:

Initial Calibration Verification: All analyte recoveries were within established limits.

Continuing Calibration Verification: All analyte recoveries were within established limits.

Flagging Codes: None were used.

NC/CAR: No NC/CAR's were Issued.

Sample Calculation: Analyte concentrations of Aroclor 1016 and 1260 in sample extracts aredetermined from the average calibration factor of standards run before the samples. For otherAroclors, single-point comparison is used. Final concentration in mg/kg is determined from theequation

c = V V DF 1 mgw 1000 jig

where

Cs = Analyte concentration in sample (mg/kg)

CE = Analyte concentration in extract (ug/mL)

VE = Final volume of extract (mL)

DF = Dilution Factor

Ws = Initial weight of sample taken for preparation (kg) 004


Miscellaneous Comments: Samples CBSSB12-1516 and CBSSB5-10123 are reported as havingsubstantial concentrations of ArocJor 1232. The patterns exhibited by these samples aresomewhat atypical of Aroclor 1232 in that the higher congeners are greatly suppressed. Inthe analyst's opinion, these samples represent either substantially weathered Aroclor 1232 ora somewhat more restricted PCB distillation cut than is usual for Aroclor 1232.

General Information

The DCL QC Database maintains all numerical figures which are input from the pertinent datasource. These data have not been rounded to significant figures nor have they been moisture corrected.Reports generated from the system, however, list data which have been rounded to the number ofsignificant figures requested by the client or deemed appropriate for the method. This may createminor discrepancies between data which appear on the QC Summary Forms (Forms B-G) and those that wouldbe calculated from rounded analytical results. Additionally, if a moisture correction ic performed,differences will be observed between the QC data and the surrogate data reported on Form A (or otherreport forms) and corresponding data reported on QC Summary Forms. In these cases, the Form A willindicate the "Report Basis* as well as the moisture value used for making the correction.Report generation options :X
