i <br /> Drill-outs—46 wells <br /> Impacted monitoring and remediation wells, specifically <br /> MW-1 BB <br /> MW-4BB <br /> MW-5BB <br /> MW-6BB <br /> MW-7136 <br /> MW-9BB <br /> MW-16BB <br /> EX-1 BB <br /> All ASO wells (14 wells, TDs range from 70 to 80 feet bsg) <br /> All AS wells (24 wells, TDs all 75 feet bsg) <br /> Pressure Grouting —45 wells <br /> Unimpacted or cleaned-up monitoring wells, specifically <br /> MW-2BB <br /> MW-3BB <br /> MW-8BB <br /> MW-10BB <br /> MW-11 BB <br /> MW-12BB <br /> MW-13BB <br /> MW-14BB <br /> MW-15BB <br /> MW-17BB <br /> MW-18BB <br /> MW-19BB <br /> Deep wells with steel conductor casings to 77 feet bsg, PVC to 95 feet bsg (Screen 85- <br /> 95' bsg) <br /> DW-1 BB <br /> DW-2BB <br /> DW-3BB <br /> DW-41313 <br /> All VE wells (15 wells, TDs all 40 feet bsg) <br /> All VEO wells (14 wells, TDs 20 and 40 feet bsg) <br /> DTW in the area was recently at approximately 53 feet bsg, the vapor extraction wells (VE) were <br /> typically 40 feet deep, the vapor extraction observation wells (VEO) are mostly 40 feet deep, four <br /> are 20 feet deep. I've been informed that most vapor wells have 2-ft screens set just above <br /> groundwater table to capture vapor sparged from groundwater and that minimal soil <br /> contamination is associated with the release. <br />
