Introduction

This quality assurance review is based upon a review of all data generated from the 17 aqueous• samples and 12 aqueous field blank and trip blank samples that were collected during March

1991 for the Ruetgers-Nease Chemical Company, Inc. State College Site. The samples that haveundergone a rigorous quality assurance review are listed on Table 1.

This review has been performed with guidance from the "Functional Guidelines for EvaluatingOrganics Analyses With Modifications for Use Within Region III" (U.S. EPA, 1988).

The reported analytical results are presented as a summary of the data in Section 2. All of theanalytical data were examined to determine contractual compliance relative to the analyticalrequirements and deliverables specified in the U.S. EPA Contract Laboratory Program (CLP)protocol. Qualifier codes have been placed next to results so that the data user can quicklyassess the qualitative and/or quantitative reliability of any result. Details of this qualityassurance review are presented in the narrative section of this report:. This report was preparedto provide a critical review of the laboratory analyses and reported analytical results. Rigorousquality assurance reviews of laboratory-generated data routinely identify various problemsassociated with analytical measurements, even from the most experienced and capablelaboratories. The nature and extent of problems identified in this critical review should not. beinterpreted to mean that those results that do not have qualifier codes are less than valid.

Section 1 Quality Assurance Review

A. Organic Data Evaluation

Seventeen aqueous samples and 12 aqueous field blank and trip blank samples were analyzed forthe Target Compound List (TCL) volatiles by the Contract Laboratory Program (CLP) protocolsas specified on Table 1. The CLP analyses were performed by Lancaster Laboratories ofLancaster, Pennsylvania.

The findings in this report are based upon a rigorous review of holding times, blank analysisresults, surrogate recoveries, matrix spike recoveries, GC/MS tuning, target compound matchingquality, calibrations, internal standard areas and the quantitation of positive results.

Overall, the organic data is good. Contractual criteria and reporting requirements were met forthis data set, with the exception of the following. It should be emphasized that the followingitems are contractual in nature and do not necessarily affect data usability. Data usability is

j addressed separately.

Correctable Deficiencies

1. Most of the SMC Environmental Services Group sample numbers are not reported on theQC summary forms exactly as they appear on the Chain-of-Custodies. The reviewer hasopted to refer to the laboratory reported SMC Environmental Services sample numbersin this report.

2. Volatile Tentatively Identified Compounds (TICs) Form I's were not providedfor samples 1029-DL, 1320DL, 10547DL, 4MW21DL, SUMP2DL, SUMP2DL2 and4MW23DL.

3. A Volatile Continuing Calibration Form (Form VII) was not provided for the continuingcalibrations performed on instrument OWA01930 on 3/20/91 at 13:33.

4. In the volatile chromatogram of most samples, there is a peak that elutes within the first3 minutes of the analytical run, which has an apparent peak height greater than 10percent of the associated internal standard and was not library searched. This peak,although most likely due to an air leak (CO ) or a solvent front (methanol), should havebeen library searched.

5. The laboratory reported the results for the matrix spike compounds on the Form I's forthe volatile matrix spike/matrix spike duplicate analyses. Per the CLP protocol, onlynon-matrix spike compounds should be reported on the Form I's.

6. The following discrepancies were observed between the raw GC/MS tuning data forbromofluorobenzene (BFB) and the reported percent abVs. None of the discrepancies impact data usability.bromofluorobenzene (BFB) and the reported percent abundances .eixtbejagflicable Form

With regard to data usability, principal areas of concern include blank contamination, duplicateanalysis results and calibrations. Based upon a review of the data provided, the followingorganic data qualifiers are offered.

Organic Data Qualifiers

Due to the trace-level presence of toluene, 1,1,2,2-tetrachloroethane, methylene chlorideand acetone in the laboratory method blanks, field blanks and trip blanks, the reportedpresence of toluene, 1,1,2,2-tetrachloroethane, methylene chloride and acetone in thefollowing samples is qualitatively questionable and the results have been flagged "B" onthe data tables.

Compound Applicable Samplestoluene 1029, 1029-DL, 14MW1,

4MW21 and 4MW21DL

1,1,2,2-tetrachloroethane 9932, 10320, 10320DL and SUMP2methylene chloride 9727, 1029, 4MW21 and SUMP2

acetone 9231, 9727 and 9932

Although the results for methylene chloride in sample 4MW21, for toluene in samples4MW21 and 4MW21DL, and for 1,1,2,2-tetrachloroethane in samples 10320 and10320DL appear to be substantial, these results actually represent trace-level instrumentlevels, similar to those observed in blanks, multipliedJJK i r&e ilution factors.

Environmental Standards, Inc.

-page 3

Although the reported result for 1,1,2,2-tetrachloroethane in sample 10547DL is at aconcentration that can be questioned by the blanks, the reviewer has not qualified theseresults with a "B." The concentration of this compound in the initial analysis of theaforementioned sample was substantial enough that it could not be qualitativelyquestioned.

Although there is no direct reason to qualitatively question the presence of acetone insamples MW29, MW7 and 1029, these results should be used with caution. Acetone isa common laboratory contaminant.

The positive results for the compounds in the following samples should be consideredestimated and have been flagged "J" on the data tables. The instrument levels of thecompounds in these samples exceeded the calibration range.

The positive results for the compounds in the following samples should be consideredestimated and have been flagged "J" on the data tables. High percent differences wereobtained between the results obtained for the compounds in the initial undiluted analysesand the results obtained for the compounds in the dilution analyses and/or reanalyses ofthese samples.

The analysis for 2-butanone in samples 11530, 11830, 119FB, 120TB, 316FB, MW3,MW29, MW7, MW6, 122TB, 89FB, 90TB, 9125, 9231, 9727, 9932, 100FB, 101TBand 4MW23DL is unreliable and the "not-detected" results have been flagged "R" on thedata tables. A low average relative response factor (<0.05) for 2-butanone wasobserved in an associated continuing calibration standard or in an associated initial multi-point calibration standard.

The positive results for acetone in samples 89FB, 100FB and 101TB and for carbondisulfide in sample SUMP2 should be considered estimated and have been flagged "J"on the data tables. A high percent difference was obtained between the response factorfor acetone and carbon disulfide in the associated continuing calibration and the averageresponse factor for acetone and carbon disulfide in the associated initial calibrationstandard.

Tentatively Identified Compounds (TICs) for the VOA analyses performed have beenevaluated and are presented on the data tables. The majority of the TICs appear to beunknowns, alkylbenzenes, alkanes and blank contaminants.

Per CLP protocols, all results reported below the quantitation limits should be consideredestimated and have been flagged "J" on the data tables.

A complete support documentation of this quality assurance review is presented in Section 3 ofthis report.

B, Conclusions

This quality assurance review has identified several aspects of the data that requiredqualification. Overall, the date results are acceptable for use and represent good laboratoryperformance. However, a small portion of the data has been qualified due to sample matrixproblems and laboratory quality control standard results. To confidently use any of the data inthe sample set, the data users should understand the limita.tions and qualifications presented inthis report.
