Data Verifiers: Michelle Wolfe and Tammy Chang

INTRODUCTION

The following data verification summary report covers environmental soil samples and associated field quality control (QC) samples collected from the Camp Stanley (under RL83) on April 3, 2000. Samples in the following laboratory Sample Delivery Group (SDG) were analyzed for semivolatile organic compounds (SVOCs); volatile organic compounds (VOCs) and selected metals including barium, chromium, copper, nickel, zinc, arsenic, cadmium, lead and mercury:

Field quality control samples collected were trip blank and field duplicate. During the initiation of this project, it was determined that ambient blanks were not necessary due to the absence of a source at the site. The trip blank was analyzed for volatile organics only.  The field duplicate sample was analyzed for the same parameters as the parent sample.

All samples were collected by Parsons Engineering Science (Parsons ES).  All analyses were performed by APPL, Inc. following procedures outlined in the AFCEE QAPP, version 3.0.

EVALUATION CRITERIA

The data submitted by the laboratory has been reviewed and verified following the guidelines outlined in the AFCEE QAPP, version 3.0.  Information reviewed in the data packages include sample results; the summary of laboratory quality control results; case narrative; raw data; and chain-of-custody forms.  The analyses and findings presented in this report are based on the reviewed information, and whether guidelines in the AFCEE QAPP were met. 

SVOC SDG 32352

General

This SDG consisted of nine (9) samples, including eight (8) confirmation environmental soil samples and one field duplicate soil sample.  The samples were collected on April 3, 2000 and analyzed for semivolatile organic compounds (SVOCs).

SVOC analyses were performed using United States Environmental Protection Agency (USEPA) SW846 Method 8270C.  All samples for this SDG were analyzed following the procedures outlined in the AFCEE QAPP.  All samples collected were prepared and analyzed within the holding times required by the method.

Accuracy

Accuracy was evaluated using the percent recovery (%R)s for the LCS sample and surrogate spikes.  There was no MS/MSD analyzed in association with this SDG.

All LCS %Rs were within acceptance criteria except for as follows:

LCS � 4/7/00 - soil

Analyte

%R

QC

4-chloroaniline

benzoic acid

32.6

20.1

35-146

25-172

AFCEE chemist and Parsons chemist agreed on April 27, 2000 that �R� flags would not be applied to 4-chloroaniline data in associated soil samples. The benzoic acid results in the associated soil samples were considered unusable and flagged �R�.

The surrogate %Rs were within acceptance criteria.

Precision

Sample B4-SB07 (14.0-15.0�) FD was the field duplicate of sample B4-SB07 (14.0-15.0�).  All field duplicate RPDs were within acceptance criteria.

Completeness

Completeness has been evaluated by comparing the total number of samples collected with the total number of samples with valid analytical data. 

The benzoic acid results in the soil samples were considered unusable and flagged �R� due to low LCS %Rs.  The completeness for this SDG is 99.3% compared to the minimum acceptance limit of 90%.

Representativeness

Representativeness expresses the degree to which sample data accurately and precisely represents actual site conditions.  Representativeness has been evaluated by:

        Comparing the chain-of-custody procedures to those described in the AFCEE QAPP;

        Comparing actual analytical procedures to those described in the AFCEE QAPP;

        Evaluating holding times; and

        Examining laboratory blanks for cross contamination of samples during the  analysis.

All samples in this SDG were analyzed following chain-of-custody forms (COCs) and analytical procedures described in the AFCEE QAPP.  All samples were prepared and analyzed with the holding times required for the analysis.

        All instrument performance check criteria were met.

        All initial calibration criteria were met.

        All continuing calibration criteria were met.

        All second source verification criteria were met.

        All internal standard criteria were met.

There was one method blank associated with the SVOC analyses in this SDG.  The blank was free of SVOCs above the RL.

VOC SDG 32352

General

This SDG consisted of ten (10) samples, including eight (8) confirmation environmental soil samples, one field duplicate soil sample and one trip blank sample.  The samples were collected on April 3, 2000 and analyzed for volatile organic compounds (VOCs).

Accuracy

Accuracy was evaluated using the percent recovery (%R)s for the LCS sample and surrogate spikes.  There was no MS/MSD analyzed in association with this SDG.

All LCS and surrogate %Rs were within acceptance criteria.

Completeness

Completeness has been evaluated by comparing the total number of samples collected with the total number of samples with valid analytical data. 

All the results were considered usable.  The completeness for this SDG is 100.0% compared to the minimum acceptance limit of 90%.

Representativeness

Representativeness expresses the degree to which sample data accurately and precisely represents actual site conditions.  Representativeness has been evaluated by:

        Comparing the chain-of-custody procedures to those described in the AFCEE QAPP;

        Comparing actual analytical procedures to those described in the AFCEE QAPP;

        Evaluating holding times;

        Examining field and laboratory blanks for cross contamination of samples during collection or analysis.

All samples in this SDG were analyzed following chain-of-custody forms (COCs) and analytical procedures described in the AFCEE QAPP.  All samples were prepared and analyzed with the holding times required for the analysis.

        All instrument performance check criteria were met.

        All initial calibration criteria were met.

        All continuing calibration criteria were met.

        All second source verification criteria were met.

        All internal standard criteria were met for the continuing calibrations.  There was one sample that had non-compliant internal standards. Sample B4-SB06 (0-0.5) had a %recovery of 44.2% for 1,4-dichlorobenzene.  The SW846 Method 8260B (section 7.4.7) specifies that the continuing calibration internal standard areas be compared to the initial calibration internal standard data.  However, there is no mention of any QC criteria for the samples internal standard areas.  Therefore no action was taken for the sample with non-compliant internal standards.

There were two method blanks (one for soil and one for water) and one trip blank associated with the VOC analyses in this SDG.  The blanks were free of VOCs above the RL.
