Split Sample Data Comparison Report Cleburn Street OU5 Site

Treatability Study/Pilot Test

Split Sample Data Comparison

This report details the analytical results obtained by ThermoRetec (TR) samples and JFO split- samples. On December 16,1999, TR collected four soil vapor extraction (SVE) system samples for analysis at an off-site laboratory. JFO collected three split-samples to verify performance of the PRP’s laboratory. On January 18,2000, TR collected one SVE sample and JFO collected one split- sample.

Table 2 presents the analytical results of samples and split-samples that were collected during the treatability study. Complete laboratory packages are presented in Attachments A, B, and D. A data validation was performed on the JFO split-samples to evaluate the quality of the data. The Technical Memorandum is presented in Attachment C.

The laboratory method used by both labs for sample analysis was TQ-14 - Determination of Volatile Organic Compounds in Ambient Air. By using the same method, a direct comparison with the PRP data can be made using a percent difference calculation (Table 3).

According to the QAPP, if analytical results obtained during this activity exceed a percent difference of 100%, then additional data review and data coding limiting the useability of the data may be required. Factors to be considered may include the presence of detectable concentrations and contaminant levels of concern. Additional sampling activities may be required as directed by the EPA WAM.

As shown in Table 3, three analytical results were above the 100% difference level. All three analytes exceeding the 100% difference were in the “0-3 hours after start-up” sample. The percent difference for cis-l,2-dichloroethene, ethylbenzene, and methylene chloride were 191.0%, 155.0%, and 128.8%, respectively.

For the analyte, cis-l,2-dichloroethene, the PRP sample concentration was <6,000 ppb and the JFO sample concentration was 260,000 ppb. The PRP sample is questionable since the trend in subsequent sample and split-sample results are much higher and provide a better correlation (i.e. 3-6 hour sample - PRP 340,000 ppb/JFO 300,000 ppb; 6-9 hour sample - PRP 270,000 ppb/JFO480,000 ppb).

For the analyte, ethylbenzene, the PRP sample concentration was 60,000 ppb and the JFO sample concentration was 7,600 ppb. A dilution was performed on the JFO sample which resulted in a concentration for ethylbenzene of 66,000 ppb. If a percent difference calculation was performed using the dilution result, then the percent difference would be 9.5%, well below the percent difference threshold stated in the QAPP.

For the analyte, methylene chloride, the PRP sample concentration was <6,000 ppb and the JFO , sample concentration was 1,300U ppb. Both of the samples were less than the detection limit.

Therefore, the discrepancy does not pose a problem with the sample results.

The two data sets generally have a high correlation, with minor variances in percent difference calculations in the “0-3 hours after start-up” sample.

DATE: March 3,2000

TO: Laura Roland, Project Manager

FROM: Ethan Litsey, Project Chemist

SUBJECT: Quality Control Review of Split Sample DataPilot Test of SVE System

REFERENCE: Clebum Street OU5 - Treatability Study Project Number C6015500/019

1.0 INTRODUCTION

This Technical Memorandum (Memorandum) presents an evaluation of the quality of split sample data collected for use for the referenced project. The data are intended to be used in the evaluation of the analytical data collected by the Potentially Responsible Party (PRP). The intent of this Memorandum is to document the quality of split sample data and to document any limitations to the use of these data with respect to their intended uses.

1.1 Project Samples Evaluated in this Review

Four (4) air samples were collected as collocated split samples and were distributed for analysis to a 'laboratory independent of the PRP laboratory. Samples were collected in accordance with the sampling

procedures set forth in the PRP's Field Sampling Plan (FSP).

1.2 Analytical Laboratory

The laboratory used to analyze the split samples was:

S:\SVE_PROJ\000155\019\REPORTSVTREAT ST\DI9 DV.RVO Technical Memorandum - Split Sample Data Quality Review

1.3 Analytical Methods

In order to promote data comparability, the analytical laboratory was required to perform testing within the guidelines of standardized, EPA approved protocols. Required analyses were performed in strict accordance with Compendium of Methods for the Determination of Toxic Organic Compounds in Ambient Air, EPA/625/R-96/010b, USEPA, January 1997. Specific analytical methods used in the analysis of the split samples included:

• TO-14A - Determination of Volatile Organic Compounds in Ambient Air

1.4 Data Evaluation Procedure

The quality of this data has been evaluated in accordance with procedures presented in the approved QAPP and the referenced analytical protocol. The procedures are based on EPA guidance document USEPA Contract Laboratory Program National Functional Guidelines for Organic Data Review, EPA-540/R-94- 014, February 1994 (Functional Guidelines). Data evaluation was performed by qualified JFO personnel, experienced in the evaluation of analytical data quality.

The following data quality issues were addressed in this evaluation:

• Sample Integrity, Holding Times, and Sample Preservation• Method Blank Samples• Surrogate Compound Percent Recoveries• Laboratory Control Sample Percent Recoveries• Sensitivity• Sample Quantitation• Completeness• Overall Assessment and Data Use.

e

It was the laboratory's responsibility to verify many data quality issues required for the generation and reporting of definitive data. This was ensured by the requirement of the laboratory to follow the appropriate, approved method which includes rigorous QA/QC procedures. Review issues which were not addressed in this evaluation, but were the responsibility of the laboratory, included: •

• Review of data summaries and reports for transcriptional and typographical errors.• Review of laboratory internal chain-of-custody forms and analysis logbook data.• Ensure acceptable instrument initial and continuing calibration.• Ensure acceptable instrument performance (tune) at the beginning of each 12 hour analysis period

by analysis of a bromofluorobenzene (BFB) standard.• Ensure acceptable internal standard performance.• Verification of results calculations.

1.5 Data Qualifier Definitions

The following definitions describe the data qualifiers which may be assigned to results during this review.The data qualifiers used were based on those included in the Functional Guidelines.

U- The analyte was analyzed for, but was not detected above the reported sample quantitation limit.

J- The analyte was positively identified; however, the associated numerical value is an estimate ofthe concentration of the analyte in the sample.

UJ- The analyte was not detected above the reported sample quantitation limit. However, the reported quantitation limit is an estimate and may or may not represent the actual limit of quantitation necessary to accurately and precisely measure the analyte in the sample.

R- The sample results are rejected and are therefore unusable due to serious deficiencies in the ability to analyze the sample and meet quality control criteria. The presence or absence of the analyte cannot be verified.

2.0 DATA QUALITY NARRATIVES

Specific findings of this evaluation were discussed in data quality narratives in terms of PARCC data quality parameters. The discussions provide an assessment of the potential impact those results had on the analytical data.

2.1 Sample Integrity, Holding Times, and Sample Preservation

Review of sample chain of custody (COC) and sample receipt records indicate that sample integrity and tustody was maintained. The referenced analytical method does not contain specific requirements for technical holding time or sample preservation.

23, Method Blank Samples

Contamination of samples resulting from laboratory conditions or procedures was evaluated by review of the reported method blank sample results. Acetone was detected at a low level in one method blank potentially impacting data representativeness. However, acetone was not detected in project samples, thus the method blank contamination had no impact on project sample quality.

23 Surrogate Compound Percent Recoveries

Method performance on individual samples was monitored by evaluation of surrogate compound percent recovery data. Surrogate percent recoveries were found to be in control for all reported project samples and laboratory internal QC samples.

S:\SVE_PROJ\000155VU 9Mt£PORTS\TREAT_STV) 19D VRVO 3 Technical Memorandum. Split Sample Data Quality Review

2.4 Laboratory Control Sample Percent Recoveries

Laboratory control samples were analyzed to demonstrate the accuracy of the analytical method and overall method performance. Laboratory control sample percent recoveries were found to be in control demonstrating acceptable accuracy.

2.5 Sensitivity

Sensitivity was evaluated by review of laboratory reported detection limits and analysis dilution factors. The sensitivity of an analysis decreases as the dilution factor increases, resulting in detection limits increased by a factor equal to the dilution factor. Project samples were analyzed at dilution factors ranging from 503 to 13600. Subsequent non-detect data will have corresponding elevated detection limits.

2.6 Sample Quantitation

Sample results are required to be within the concentration range of the instrument calibration in order to achieve accurate and precise quantitation. When the laboratory results were beyond the calibration range of the instrument, the laboratory flagged those concentrations with an “E” and should also supply results for a sample analyses at a larger dilution factor to quantitate the specific compounds E flagged. In these cases, it is necessary to report the results from the lowest dilution analysis which were not flagged with E. In cases where the laboratory did not supply an additional diluted sample analysis, the result is flagged with a “J” to convey that it is an estimated value.

Two “E” flagged compounds were reported by the laboratory in sample #1 (Lab Id 41543.01) analyzed at a dilution factor of 1340: tetrachloroethene at 190,000 E ppbv and cis-l,2-dichloroethene at 220,000 E ppbv. These results should be replaced with results from the reanalysis (secondary dilution at a 10 fold higher dilution factor of 13400) of tetrachloroethene at 630,000 ppbv and cis-l,2-dichloroethene at 260,000 ppbv. No other results should be reported from the secondary dilution analysis.

One “E” flagged compound was reported by the laboratory in sample #3 (Lab Id 41543.03) at a dilution factor of 13400: tetrachloroethene at 1,400,000 E ppbv. Since no secondary dilution was reported for this sample, the result should be qualified with a “J” for estimated.

2.7 Completeness

Completeness was found to be 100% for all evaluated data. Data are considered usable as qualified for the intended purposes.

2.8 Overall Assessment and Data Use

These data are useable as reported with the qualifications noted in the above text and summarized below.

• sample #3 (Lab Id 41543.03) tetrachloroethene concentration is qualified J for estimated: tetrachloroethene = 1,400,000 J ppbv.

• Note that, sample #1 (lab Id 41543.01) was reported at two separate dilution factors. The results from the lowest dilution factor shall be used for all compounds except those flagged by the laboratory with an E (tetrachloroethene and cis-l,2-dichloroethene). The concentrations of tetrachloroethene = 630,000 ppbv and cis-1,2-dichloroethene = 260,000 ppbv from the secondary dilution shall be reported for these two compounds. See section 2.6 for details.
