Data Validators: Michelle Wolfe, Tammy Chang

Introduction

The following data validation summary report covers environmental soil samples and associated field quality control (QC) samples collected from the Camp Stanley CSSA Site B24 (under RL33) on March 30, 2000. Samples in the following laboratory Sample Delivery Group (SDG) were analyzed for semivolatile organic compounds (SVOCs); volatile organic compounds (VOCs); metals and mercury:

32337

Field quality control samples collected were trip blank; equipment blank; matrix spike/matrix spike duplicates (MS/MSD); and field duplicates. Parsons ES did not collect any ambient samples for VOC analysis due to the lack of determined source from the site. The trip blanks were 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 Laboratories, Inc. following procedures outlined in the AFCEE QAPP, version 3.0.

Evaluation Criteria

The data submitted by the laboratory has been reviewed and validated 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 32337

General

This SDG consisted of fourteen (14) samples, including nine (9) confirmation environmental soil samples, two field duplicate soil samples, one set of matrix spike/matrix spike duplicate samples and one equipment blank sample. The samples were collected on March 30, 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 time required by the method.

Accuracy

Accuracy was evaluated using the %R results for the MS/MSD samples, LCS sample, and surrogate spikes. Sample B24-SB05 (12.0-14.0�) was analyzed as the MS/MSD sample for this SDG.

All MS/MSD %Rs were within acceptance criteria except for the following:

Sample B24-SB05 (12.0-14.0�)
Analyte	MS %R	MSD %R	QC
Bis(2-ethylhexyl)phthalate	-676.5	-611.8	25-139

The bis(2-ethylhexyl)phthalate results in the samples from the same site and of similar matrix as the MS/MSD sample were flagged �M� to indicate a matrix effect was present.

All LCS and surrogate %Rs were within acceptance criteria.

Precision

Precision was evaluated using the Relative Percent Difference (RPD) results obtained from MS/MSD results; and the field duplicate analyte values. Sample B24-SB05 (12.0-14.0�) was analyzed as the MS/MSD sample for this SDG. Sample B24-SB03 (0.0-0.5�) FD was the field duplicate of sample B24-SB03 (0.0-0.5�). Sample B24-SB05 (12.0-14.0�) FD was the field duplicate of sample B24-SB05 (12.0-14.0�).

All MS/MSD and field duplicate RPDs were within acceptance criteria except sample B24-SB05 (12.0-14.0�) contained 14 mg/kg of bis(2-ethylhexyl)phthalate and its field duplicate sample contained 0.26 mg/kg (less the RL) of the same compound. The %RPD calculation is not applicable.

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; and
	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 within the holding time required for the analysis.
