Site Characterization Report: 7500 West Eleventh Street, Tracy, CA Page 17 <br /> 1,2-Dichloroethane (1,2-DCA) EPA Method 8260A <br /> Total Lead EPA Method 200.7 <br /> * The fuel oxygenates for which the groundwater samples were analyzed were: tertiary- <br /> Butyl alcohol (TBA), Methyl-tertiary butyl ether (MTBE), Di-isopropyl ether (RIPE), <br /> j Ethyl tertiary-butyl ether(ETBE), and tertiary-Amyl methyl ether(TAME). <br /> The results of the analyses of samples of groundwater are presented in Table 2. <br /> 3.8 Disposal of Drill Cuttings and Well Development and Purge Water <br /> The drilling of borings, development of wells and well purging generated drill cuttings <br /> and water potentially affected by petroleum hydrocarbons. As the subsurface <br /> investigation progressed, these materials were placed in open-topped 50-gal. drums <br /> equipped with sealable lids. The drums were temporarily staged on the 7500 West <br /> Eleventh Street property. <br /> When the results of the analyses of soil and groundwater results were available, the <br /> drummed soil and water was classified and water unaffected by analytes of concern was <br /> ;- discharged to the ground surface of the 7500 West Eleventh Street property; clean soil <br /> was mingled with the native soil on the site. Drill cuttings and affected water were <br /> disposed off-site as follows. <br /> 3.8.1 Disposal of Drill Cuttings <br /> Drill cuttings affected by petroleum hydrocarbons were removed from the drums and <br /> loaded onto a truck for disposal at Forward, Inc.'s Class II facility in Manteca, California. <br /> 3.8.2 Disposal of Well Development and Purge Water <br /> On June 21, 2000, 300 gal. of well development and purge water was transferred from the <br /> 50-gal. steel drums into a vacuum struck and transported to the Demenno Recycling <br /> Facility in Compton, California for disposal. <br /> The empty drums that had been used to store the drill cuttings and well development and <br /> purge water were cleaned and have been retained on the 7500 West Eleventh Street <br /> property, where they will be used to store purge water from future rounds of groundwater <br /> sampling and analysis. <br /> i -? <br /> i <br /> sic <br /> l <br />
