Boerne, TEXAS

Data Verifiers: Michelle Wolfe & Tammy Chang

INTRODUCTION

The following data verification summary report covers environmental soil samples and associated field quality control (QC) samples collected from the CSSA Site (under RL53) on March 1, 2000. Samples in the following laboratory Sample Delivery Group (SDG) were analyzed for volatile organic compounds (VOCs) and metals including barium, chromium, copper, nickel, zinc, mercury, arsenic, cadmium and lead:

Field quality control samples collected were trip blank and field duplicate.� The trip blank was analyzed for volatile organics only.� The field duplicate sample was analyzed for the same parameters as its parent sample. 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.

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 (COC) forms.� The analyses and findings presented in this report are based on the reviewed information, and whether guidelines in the AFCEE QAPP were met.�

VOC SDG 32116

General

This SDG consisted of twelve (12) samples, including ten (10) confirmation environmental soil samples, one field duplicate soil sample and one trip blank sample.� The samples were collected on March 1, 2000 and analyzed for volatile organic compounds (VOCs).

VOC analyses were performed using United States Environmental Protection Agency (USEPA) SW846 Method 8260B. 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 time required by the method.

Accuracy

Accuracy is normally evaluated using the %R results for the MS/MSD samples; LCS samples; and surrogate spikes.� There was no MS/MSD analysis requested on the COC.

All LCS %Rs were within acceptance criteria.

The surrogate %Rs were within acceptance criteria.

Precision

Precision is normally evaluated using the Relative Percent Difference (RPD) results obtained from MS/MSD results; and the field duplicate analyte values.� There was no MS/MSD analysis requested on the COC.� Sample BLD43-SB01 (0.5-1.0�) FD was the field duplicate of sample BLD43-SB01 (0.5-1.0�).
