1.0 INTRODUCTION
The U.S Environmental Protection Agency (EPA) requested TRC Environmental Corporation (TRC) to provide compliance oversight for the Remedial Investigation/Feasibility Study (RI/FS) being performed at the Tansitor Electronics site (site) located in Bennington, Vermont. TRC has performed a comparison of the results of the split sample analysis to the GZA data presented in the Phase 1A Characterization Report (Phase 1A Report) dated March 23, 1992.
2.0 COMPARISON OF EPA/TRC AND GZA SPLIT SAMPLE ANALYTICAL DATA
2.1 Introduction
TRC was directed by the EPA WAM to collect ten water and nine soil/sediment split samples at the Tansitor Electronics site. A list of these samples is presented in Table 1-1. The split samples were obtained in accordance with TRC's EPA-approved Field Oversight Work Plan dated November 27, 1991.
The EPA/TRC samples were analyzed through the EPA Contract Laboratory Program (CLP) for volatile organics (including TCL compounds, chlorodifluoromethane, trichlorotrifluoroethane, cyclopentane, N,N-dimethylformamide, methanol), TCL semivolatiles, TCL pesticides/PCBs, inorganics (including TAL metals, palladium, tantalum and total cyanide). The GZA samples were analyzed by similar methods for the above analytes by Aquatec, Inc.
The objective for split sample collection during this effort was to quantitatively compare analytical results obtained by GZA to those from the EPA/TRC samples. Where analytical results were not available from either EPA/TRC or GZA, no data comparison is provided.
Appendix A provides summary tables comparing validated analytical results from the GZA split samples with the validated results of the EPA/TRC split samples. All of the GZA analytical data presented in Appendix A were downloaded from the dBASE compatible diskettes submitted by GZA for the Risk Assessment
2.2 Quality Control Review of EPA/TRC Data
Validation of the EPA/TRC data was performed in accordance with Region I guidance by TRC's subcontractors, Dynamac and Quantalex. All validated EPA/TRC data was previously submitted to EPA. A review of the EPA/TRC data validation reports indicates that although most of the data were acceptable, some data points were estimated and a few data points were rejected due to laboratory quality control problems.

2.3 Split Sample Comparison
2.3.7 Comparability Goal
Presently, there is no EPA published guidance pertaining to the quantitative comparison of split samples which are analyzed by two different laboratories. Consequently, TRC has utilized a comparison procedure that calculates the relative percent difference (RPD) of detected compounds in each data set A quantitative comparability goal, which originated from Region I data validation guidance for the evaluation of field duplicates, is then applied to the calculated RPD to evaluate the comparability of the split samples. The comparability goal for organic results is a RPD of 30% for water samples and 50% for soil samples. For inorganic results above five times the contract required detection limit (CRDL), the comparability goal is a RPD of 30% for water samples and 50% for soil samples. For inorganic results where one or both split sample results are below five times the CRDL, the comparability goal is an absolute difference of less than the twice the CRDL for waters and four times the CRDL for soils.
Accordingly, the GZA and EPA/TRC data were quantitatively compared by applying the above criteria to the results of split sample analyses. The quantitative comparison is presented in Appendix A. The Appendix A data tables were also reviewed to determine instances where analytes were detected by EPA and were not detected by GZA.
2.5.2 Comparability Evaluation
TRC further evaluated the Appendix A split sample comparison data tables to determine whether any of the GZA results, which did not meet RPD comparability goals, might still be considered useable. The comparability goals which were applied to the data are based on the expected precision of field duplicate samples analyzed at a single laboratory. However, the split samples evaluated in this report were not analyzed at the same laboratory. Consequently, strict application of the RPD goals , cited above may not be appropriate. Using professional judgement TRC determined that data which did not meet comparability goals should not be considered unusable if the following conditions applied:
• if the analyte was detected by EPA/TRC at a concentration below the CRQL/CRDL and was not detected by GZA;
• if the GZA result was greater than the EPA/TRC result; and
• if one or both results were estimated (flagged with a "J") and the RPD was below a broader acceptance criteria of 67%.

Table 1-2 presents the results of the data comparability evaluation. Samples identified with an "X" in the table were judged to have inadequate comparability based on the quantitative RPD goals and TRC's professional judgement.
2.3.3 Conclusions/Recommendations
As shown in Table 1-2, 18 of the 57 sample analyses were found to have inadequate comparability. The overall comparability for the two data sets was variable; the organics analyses had adequate comparability, whereas the inorganics water analyses exhibited the most severe comparability problems.
It should be noted that the EPA/TRC samples for pesticide/PCB indicated the presence of some contaminants at levels below the PRP detection limit
From the results of the split sample comparison, TRC recommends the following:
• All analyses exhibiting inadequate comparability be confirmed for accuracy by GZA.
• Due to the discrepancies noted and the large size of the EPA/TRC split sample database, EPA should incorporate the EPA/TRC split samples data into the Risk Assessment.
• Due to the presence of methanol in samples MW-103R and MW-104M, EPA should consider requiring the PRP to add methanol to their analyte list for future analysis of ground water.
• The findings of the split sample comparison should be compared to health based risk criteria such as MCLs or to the results of the risk assessment to evaluate their additional impact.
• EPA should note the analytical discrepancies cited in this report for future users of the GZA data set.
