Data Validation Summary <br /> 2870 Gateway Oaks Drive,Suite 300 <br /> Sacramento,CA 95833 <br /> Telephone—(916)679-2000 <br /> Fax—(916)679-2900 <br /> +w TO: Tony Mindling <br /> FROM: Sacramento QA/QC Group FILE: 17322736.07003 <br /> 4.0 <br /> DATE: February 3, 2004 SITE: American Forest Products <br /> '-' SUBJECT: Summary of Data Validation for American Forest Products-4Q03 <br /> STL Project: G3L190337 <br /> `' A check for data completeness (Completeness Check) was performed by the Sacramento QA/QC <br /> Group on STL Report G3L190337. This report contains analytical data for seven aqueous <br /> samples: DMW-1, DMW-2, DMW-3, DMW-4, DMW-5, DMW-6, and DMW-7. The samples <br /> were collected on December 18, 2003, and submitted to STL in West Sacramento, California, for <br /> analysis. The analyses requested include TPH-Diesel (EPA 8015M) and Volatile Organic <br /> Compounds including oxygenates and 1,2-DCA (EPA 8260B). <br /> The data were reviewed in accordance with analytical methods outlined in SW-846. The data <br /> were evaluated based on the following parameters. <br /> ✓ Data Completeness <br /> ✓ Holding Times <br /> ✓ Blanks <br /> ✓ Laboratory Control Samples <br /> ✓ Matrix Spike/Matrix Spike Duplicates <br /> ✓ System Monitoring Compounds (Surrogates) <br /> ✓ Field Duplicates <br /> ✓ Compound Identification and Quantification <br /> The following presents an overview of the Completeness Check: <br /> �. All analyses were performed as requested on the chain-of-custody record and all holding <br /> times were met except for the reanalysis of samples DMW-1, DMW-4, and DMW-7. These <br /> .. samples were reanalyzed due to low surrogate recoveries. Since the low surrogate recovery <br /> was confirmed in sample DMW-7, the data from the reanalysis was not reported. However, <br /> acceptable recoveries were obtained in the reanalysis of samples DMW-1 and DMW-4. <br /> Consequently, the data from the reanalysis of samples DMW-1 and DMW-4 may be biased <br /> low for holding time exceedances and was reported. <br /> • All associated blanks were free of contamination. <br /> • All Laboratory Control Sample recoveries were within laboratory acceptance limits. <br /> +-. • An assessment of matrix effects can not be made since an MS/MSD analysis was not <br /> performed due to insufficient sample volume. <br /> �.
