A1.0 SAMPLING DESIGN <br /> Soil,sediment, surface water,groundwater,and soil vapor samples will be collected as part of the <br /> investigation at the AM&C site. This section describes the types of samples t will be collected and <br /> standard procedures for sampling the various matrices. These procedures are esigned to maintain proper <br /> sample integrity throughout the sampling and analysis process. <br /> All investigation-derived waste associated with decontamination of equipment and any PPE used during <br /> field activities,will be properly sampled,labeled,and disposed of following tf.a completion of excavation <br /> activities. <br /> A1.1 Analytical Methods <br /> The following analytical methods will be used for this project. All cited EPA ethods are from Test <br /> Methods for Evaluating Solid Waste, SW-846,Update III(EPA, 1998c). The t st methods to be <br /> performed for each sampling site is determined based on previous investigatio s and current data gaps as <br /> presented in the Workplan. <br /> • Volatile Organic Compounds (VOCs)by <br /> Gas Chromatography/Mass Spectrometry(GC/MS) 8260B <br /> • VOCs(soil vapor)by GC/MS TO-15 <br /> • Semivolatile Organic Compounds(SVOCs)by GC/MS 8270C <br /> • Pentachlorophenol by GC/MS 8270C <br /> • Dioxins and Furans by High Resolution(HR)GC/HRMS 8290 <br /> • Polychlorinated Biphenyls(PCBs)by GC 8082 <br /> • TPH as Diesel(TPHd)and motor oil(TPHmo)by GC 8015B(modi red) <br /> -(to include silica gel cleanup) 3630C <br /> • Metals by Inductively Coupled Plasma(ICP)/ICP/MS 601013/6020 <br /> • Mercury by Manual Cold Vapor Technique(CVAA) 7470A/7471 <br /> • Formaldehyde by <br /> High Performance Liquid Chromatography(HPLC) 8315A <br /> • Formaldehyde(soil vapor)by HPLC TO-11 <br /> • Phenols by GC 8041 <br /> A1.2 Sampling Methods and Procedures <br /> This section presents field methods and sampling procedures,decontamination procedures,sample <br /> handling procedures,and field documentation procedures that will be used dur ng the AM&C field <br /> KB61125 APPENDIX A MACTEC Engineering and Consult ng, Inc.
