The ends ofthc <br /> sleeve will he immediately covered with Teflon sheets and sealed kvith plastic end caps secured vwith <br /> tape. Fhe preserved samples will then he in-imediately placed under ice in a chilled container I'm- <br /> transportation to a state-certified lahoratory. Each soil sample sleeve will he labeled with borin4( <br /> location. vertical depth. sampling time- date and sampler's initials. <br /> AGF. proposes to collectOO grah (Iround water samples from within the hollow,-stem at a depth of <br /> ei0hh-five I`cet hsg. The grab water sample will he screened immediately in the field for hydrocarbon <br /> odor or visual contamination. Well construction will occur if' field observations of dissolved <br /> hvdrocarbons justify permanent and repeatable sampling locations. Wells would be constructed with <br /> sin(-,le screens_ consisting 01"a 20-foot screen section with five IQct of screen extending- above the <br /> current water table (75-95 feet hsg). <br /> following installation. the wells will be developed to maximize water flow into the well and <br /> mirtin1ize the amount of tine-grained sediment drawn into the well during pimping or hailing. <br /> Procedures for xiell installation and development are presented in Sections 4.2 and 4.3, respectively. <br /> ;.i. EQUIPMENT DECONTAMINATION <br /> .All sampling tools and brass sleeves used for sample collection will he thoroughly rinsed with clean <br /> water after washing with a solution of Alconox. All augers will be cleaned prior to advancement in <br /> each boring location. <br /> 3.-I. LABORATORY ANALYSIS <br /> Selected soil samples will be analyzed for: <br /> • Total petroleum hydrocarbons quantified as gasoline and diesel (TPH-g and 'I•P11-d) in <br /> accordance with EPA Method 8015m, <br /> • Volatile aromatic hydrocarbons: benzene, toluene. ethti'1 benzene and total xylene (BTEX) <br /> in accordance with I:PA methods 801-0 and <br /> • Oxygenated compounds: di-isopropyl ether(DIPS),ethyl tertiary-hutvl ether(ETBF), methyl <br /> tertiary-butyl ether (MTBE), tertiary-amyl methyl ether (TAME), tertiary butanol (TBA). <br /> methanol. ethanol, ethylene dihromide (IDB) and 1,7-dichloroethatle (1,?-IJC'A) in <br /> accordance with EPA Method 8260. <br /> 9drurred Gcul'.nlrunnx•ntaE.lnc. <br />
