a i "".MMI , Rnl age '1 -'� hollow-stem augers, following the standard procedures and requirements of the governing regulatory agencies. During drilling, soil samples will be collected continuously, beginning at grade and continuing to the capillary fringe of the saturated zone. The samples recovered for chemical analysis will be sealed with Teflon tape and plastic caps and placed immediately into a cooler with dry ice or ice. The soil boring will then be converted to a ground water recovery well to a depth of approximately 10 to 15 feet below the top of the saturated zone (to an anticipated total depth of 30 to 35 feet below grade) . This proposed well will be constructed of clean, 6-inch diameter, flush-threaded, Schedule 44 PVC blank and screened (0.010-1 nch slat size) casing and the required gravel pack. The top of the well shall be secured with watertight locking caps and utility boxes finished flush with the ground surface. The well construction procedures and details will be in accordance with applil. able requirements of the regulatory agencies. Task Gevelop, Sample, and Survey Wells Prior to sampling, water level measurements at each well will be recorded, and the ground water will be .inspected for the presence of free product or sheen. The recovery well willb properly The developed prior to purgingsampling. purged water will be trarsierr=u to 55-gallon drums and transported for proper disposal. During purging, pH, temperature, and conductivity readings will be taken. As these readings stabilize, indicating that the water is representative of the water in the aquifer, the samples will be collected in appropriate clean glassware. The samples will be placed in an iced cooler and transported to a California-certified laboratory. This well will be surveyed by a licensed surveyor from the top of the casings to 0.01 foot accuracy in reference to an established benchmark or a common datum. 5
