1 <br /> FORMER AMERICAN FOREST PRODUCTS ' <br /> 3.0 Groundwater <br /> CIosare Summary Report � � July 2009 <br /> URS Project 17322736 <br /> F Page 3-3 <br /> decontaminated by steam cleaning,washing in an Alconox:solution,rinsing with fresh water, and a final' <br /> L rinsing with distilled water. <br /> Purge and rinsate water were placed into a Baker tank at the site. Wastewater was removed and disposed <br /> of by Evergreen Environmental Services 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(Appendix B)accompanied each sample shipment. <br /> 3.3.2 Laboratory Analysis and QA <br /> FThe groundwater samples were submitted for analysis according to the following methods: <br /> rWells Analysis Method <br /> DMW-2,DMW-5,DMW-6, 7Tota1•Petroleum Hydrocarbons Method 8015M(Silica Gel) <br /> DMW-9, and DMW-11 as Diesel TPHd <br /> i <br /> through DMW-14 Chlorinated volatile organic EPA Method 8260B j <br /> compounds (VOCs) <br /> a and oxygenates <br /> A field duplicate was collected at DMW-9. Equipment <br /> p ansate and tap blank samples were also submitted � <br /> for analysis.Kiff performed routine laboratory quality assurance/quality control(QA/QC)analyses, <br /> including method blanks,and surrogate analyses. Laboratory analytical reports for the groundwater 4 <br /> _ samples and the associated QA/QC samples are included in Appendix C. r <br /> Data validation was performed by URS and consisted of reviewing: <br /> • Data Completeness <br /> k ; • Holding Times and Preservation i <br /> t <br /> • Blanks' <br /> i <br /> •- LaboratoryControl Samples <br /> • System Monitoring Compounds (Surrogates) ' <br /> • Field Duplicates <br /> • Compound Identification dentrficatron and Quantification <br /> FData validation results are included in the Data Validation Summary(Appendix C). The data validation <br /> found allresults to be acceptable and useable for their intended purpose. <br />(l KMprocess12273Mmericm ForestlClosur S5 ary-Rcport-RCWI.doc <br />
