Purging was accomplished by removing a minimum of three well <br /> volumes of water Water levels were measured before development. <br /> The purged water was monitored for conductivity, temperature, pH, <br /> and turbidity <br /> All purge water and rinsate was stored in sealed 55-gallon drums <br /> pending the results of laboratory analyses Each drum was clearly <br /> labeled to indicate its contents and boring number The drums were <br /> stored on site adjacent to the stockpiled soil <br /> All wells except for MW-2A were sampled using a precleaned <br /> Teflon® bailer The samples were not filtered in the field. A <br /> ' groundwater sample from MW-2A was not collected because floating <br /> product was observed in the bailed water from this well The floating <br /> product thickness measured Iess than 0 01 feet <br /> ' Water samples were placed in containers provided by the laboratory <br /> Water samples were labeled with a unique sample number, the <br /> project name and location, the date and time, and the sampler's <br /> ' initials Samples were then placed in Zip-Lack® type plastic bags, <br /> sealed, and placed in an iced cooler Information noted on the label <br /> was recorded on a chain-of-custody form After completion of <br /> drilling, the samples were delivered under chain-of-custody to a <br /> Sequoia Analytical, a California-certified laboratory <br />' Sample Analysis <br />' Selected soil samples and groundwater samples were analyzed for <br /> the following constituents <br />' 0 Total Petroleum Hydrocarbons as Gasoline (TPH-G) (EPA <br /> Method 8015-Modified), <br /> • Total Petroleum Hydrocarbons as Diesel (TPH-D) (EPA Method <br /> 8015-Modified), <br /> • Benzene, Toluene, Ethylbenzenes, and Xylenes (BTEX) (EPA <br /> Method 8020), <br /> • Total Lead (EPA Method 7421), <br /> • Organic Lead (DHS Method), and <br />' 0 Ethylenedibromide (EDB) (DHS Specified Method) <br /> 3-6 <br />
