INTRODUCTION

The following data verification summary report covers environmental soil samples and associated field quality control (QC) samples collected from the Camp Stanley Site (under RL53) on March 1, 2000.The 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:

32119

 

 

Field quality control samples collected were trip blank; matrix spike/matrix spike duplicates (MS/MSD); and field duplicates. 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.All other field quality control samples were analyzed for the same parameters as their associated samples.

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.


VOC SDG 32119

General

This SDG consisted of twelve (12) samples, including eight (8) confirmation environmental soil samples, one field duplicate soil sample, one set of matrix spike/matrix spike duplicate samples 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 times required by the respective method.

Accuracy
