for
samples collected from
Camp Stanley Storage Activity
Boerne, Texas

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 Site (under RL83) on March 6, 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, arsenic, cadmium, lead and mercury:

32150

 

 

    Field quality control samples collected were trip blank; equipment blank; and field duplicates. No ambient blanks were collected for this project.  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.  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 32150

General

    This SDG consisted of twelve (12) samples, including nine (9) confirmation environmental soil samples, one field duplicate soil sample, one equipment blank sample and one trip blank sample.  The samples were collected on March 6, 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 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 LCSs and surrogate %Rs were within acceptance criteria.

Precision

    Sample B15/16-SB02 (0.5-1.0�) FD was the field duplicate of sample B15/16-SB02 (0.5-1.0�). 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. 

    All 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 sample 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 within the holding times required for the analysis.

        All instrument performance check criteria was met.

        All initial calibration criteria were met.
