Appendix B - Monitoring and Sampling Procedures <br /> WEST CLAY PROPERTIES <br /> AGE-NC Project No. 96-0235 <br /> Page 2 of 2 <br /> SAMPLE HANDLING <br /> Ground water samples are transferred into 40-ml volatile organic analysis (VOA) vials and <br /> samples analyzed for total petroleum hydrocarbons as diesel (TPH-d) into 1-liter amber <br /> bottles without preservative. Samples are collected with no visible air bubbles present in <br /> the vials after filling and capping. Following collection, samples are appropriately labeled, <br /> placed on ice, and kept in a cooler until delivered to Cal Tech Environmental Laboratories <br /> (CTEL), a State of California Department of Public Health-certified analytical laboratory,for <br /> analysis. Samples maybe analyzed for the following: <br /> • Total petroleum hydrocarbons quantified as gasoline(TPH-g)and selected samples <br /> from the south UST area for diesel (TPH-d) in accordance with EPA Method 8015M; <br /> and <br /> • Benzene, toluene, ethylbenzene and total xylenes (BTEX) and fuel additives di- <br /> isopropyl ether (DIPE), ethyl tertiary-butyl ether (ETRE), methyl tertiary-butyl ether <br /> (MTBE), tertiary-amyl methyl ether (TAME), tertiary-butyl alcohol (TBA), <br /> 1 ,2-dibromoethane (EDB) and 1,2-DCA in accordance with EPA Method 8260B. <br /> EQUIPMENT DECONTAMINATION AND WASTE MANAGEMENT <br /> Any non-disposable equipment used for sample collection is thoroughly rinsed with clean <br /> water after being washed with a solution of Alconox. Purge water generated during <br /> sampling activities was contained on-site in an appropriately labeled 55-gallon drum. <br /> Advanced Geo Environmental,Inc. <br />
