' Purge and rinsate water were placed into a Baker tank Iocated at the site The wastewater was removed <br /> and disposed of by ABCO Environmental and manifested as non-hazardous waste based on site analytical <br /> data <br /> Laboratory-supplied sample containers and trip blanks were obtained from Kiff Analytical, LLC, (Kiff)of <br /> Davis, California, prior to the sampling events Kiff is certified by the California Department of Health <br /> Services, Environmental Laboratory Accreditation Program (DHS-FLAP) Following purging, samples <br /> were collected from each well using disposable bailers, and transferred to the appropriate laboratory- <br /> supplied sample containers through an attachment that allows a controlled flow from the bailer Sample <br /> containers were then labeled and placed into an iced cooler for shipment to the analytical laboratory via <br /> overnight carrier A completed chain-of-custody (copies of which are included in Appendix A) <br /> accompanied each sample shipment <br /> LABORATORY ANALYSIS <br /> The groundwater samples were submitted for analysis according to the following methods <br /> Wells Analysis Method <br /> DMW-1 through DMW-9 Total Petroleum Hydrocarbons as Method 8015M <br /> Diesel (TPH-D) <br /> Chlorinated volatile organic EPA Method 8260B <br /> compounds (VOCs)and <br /> oxygenates <br /> ION A field duplicate was collected at DMW-7 during each sampling round A trip blank included with the <br /> sample shipment was analyzed for chlorinated volatile organic compounds (VOCs) by EPA Method <br /> 8260B Kiff also performed routine laboratory quality assurance/quality control (QA/QC) analyses, <br /> including method blanks, and surrogate analyses Laboratory analytical reports for the groundwater <br /> samples and the associated QA/QC samples are included in Appendix B <br /> Data validation was performed by URS, consisting of a review of <br /> • data completeness, <br /> • holding times, <br /> • blanks, <br /> • system monitoring compounds(surrogates), <br /> • laboratory control samples, <br /> • matrix spike/matrix spike duplicates, and <br /> • compound identification and quantification <br /> The results of the data validation are included in the Data Validation Summaries (Appendix B) The data <br /> validation found all results to be acceptable and useable for their intended purpose with the no limitations <br /> �l <br /> D IQ4051REVIEW PACKAGE\2005 GROUNDWATER MONITORING REPORT-TEXT DOC <br />
