Additionally, two hydraulic sumps will <br /> be investigated. <br /> Proposed soil boring locations are depicted in Figure 2. <br /> 2.3. GRAB GROUNDWATER SAMPLING <br /> A grab groundwater sample may be collected from the soil borings, when the trace is <br /> advanced to approximately 25 feet bsg. For collection of a grab groundwater sample, a <br /> Geoprobe (or similar) push-driven water sampling device will be utilized. <br /> 2.4. LABORATORY ANALYSIS <br /> Selected soil and selected groundwater samples will be analyzed by a California <br /> Department of Public Health (CDPH)-certified laboratory for the following constituents: <br /> • Total petroleum hydrocarbons quantified as gasoline, diesel and oil range <br /> compounds (TPH-g.d.o) in accordance with EPA Method 8015 Modified; and <br /> Volatile organic compounds (VOCs), including chlorinated VOCs and "BTEX" <br /> compounds and fuel additives/fuel oxygenates (methyl tertiary butyl ether <br /> [MTBE], tertiary butyl alcohol [TBA], di-isopropyl ether [DIPE], ethyl tertiary butyl <br /> ether [ETBE], tertiary amyl methyl ether [TAME] and lead scavengers 1,2- <br /> dichloroethane [1,2-DCA] and 1,2-dibromomethane [EDB]) in accordance with <br /> EPA Method 8260B. <br /> Polychlorinated bi-phenols (PCBs) in accordance with EPA Method 8082. <br /> Polynuclear aromatic hydrocarbon (PNA), polycyclic aromatic hydrocarbons <br /> (PAH) or semi-volatile organic compounds (SVOCs) in accordance with EPA <br /> Method 8270. <br /> • CAM 17 Metals Total Threshold Limit Concentration (minimally: lead, cadmium, <br /> chromium, nickel and zinc) by EPA Method 6010B/6020/207/208. Soluble <br /> Threshold Limit Concentration may additionally be analyzed for metals. <br /> Advanced GeoEnvironmental Inc. <br />
