Vapor les were collected in Tedlar bags for laboratory analysis approximately 30 minutes <br /> � samples <br /> after starting the vacuum in each well tested Vapor samples were collected approximately every <br /> 5 minutes and field screened for volatile organic compounds (hydrocarbons) using 'the OVA <br /> After vapor extraction was started, vacuums in adjacent wells were periodically recorded <br /> tExtraction tests for the remaining wells were performed in the same manner as that for MW-i-P <br /> ' 4.4 Soil, Groundwater and Vapor Analyses <br /> Soil, groundwater and vapor samples were analyzed by a California State-certified,laboratory <br /> in accordance with state guidelines and EPA protocol Soil and groundwater samples were <br /> analyzed for TPH quantitated against both gasoline and diesel standards, BTEX and total lead <br /> using EPA methods 8415, 8020 and 7421, respectively Vapor Samples were analyzed for TPH <br /> ' and BTEX using EPA methods 8015 and 8020 Certified laboratory results are presented in <br /> Appendix D (soils), Appendix E (groundwater) and Appendix F (vapor) <br /> 5.0 FINDINGS <br /> ' 5.1 Existing Monitoring Wells On-Site <br /> The following table is based on Park field data collection and several previous consultant reports <br /> provided to Park by the client Existing monitoring wells will also be addressed in the <br /> Discussion section of the report <br /> I <br /> B L 125!!
