These samples were collected on June 2, 2009, as part of <br /> the American Forest Products Groundwater Monitoring Program. All samples were analyzed by <br /> Kiff Analytical in Davis, California. The following samples were analyzed: DMW-2, DMW-5, <br /> DMW-6, DMW-9, DMW-9-D, DMW-I1, DMW-12, DMW-13, DMW-14, TB-2 and EB-1. <br /> `J Field quality control samples consisting of a trip blank and equipment blank are identified as TB- <br /> 2 and EB-1, respectively. Samples DMW-9 and DMW-9-D represent a field duplicate pair. All <br /> field samples were analyzed for volatile organic compounds (VOCs) by SW8260B and total <br /> petroleum hydrocarbons (TPH)-diesel by EPA 80154 The data are acceptable in all areas of <br /> review and are useable for their intended purpose as reported. <br /> u <br /> The data were reviewed in accordance with analytical methods. The data completeness were <br /> evaluated based on the following parameters. <br /> ✓ Sample integrity <br /> ✓ Holding Times and Preservation <br /> r ✓ Blanks <br /> �k <br /> ✓ Laboratory Control Samples (LCS) <br /> ✓ Matrix Spike/Matrix Spike Duplicates <br /> ✓ System Monitoring Compounds (Surro tes) <br /> ✓ Field Duplicates <br /> The following bullets summarize the findings of the Completeness Check: <br /> • All sample vials were received in appropriate condition by the laboratories and the <br /> samples were analyzed as requested on the chains of custody. <br /> • All samples were analyzed within holding times. <br /> • The laboratory method blanks, trip blanks, and equipment blanks for both analyses were <br /> free of contamination <br /> • The VOC LCS met laboratory acceptance limits. A LCS and LCS duplicate were <br /> analyzed for TPH and met the laboratory acceptance limits. <br /> • Matrix spikes were not performed on project samples and therefore, matrix interference <br /> cannot be assessed. <br />
