subsurface migration of this compound to regional groundwater may be <br /> occurring beneath the landfill. Toluene was also detected in soil at a <br /> depth of 201 feet below ground surface. <br /> Methylene chloride and TCA were detected in elevated concentrations in <br /> landfill gas, ambient air, and integrated surface walk samples, <br /> indicating a high air release potential. <br /> It appears that the landfill poses a threat to groundwater and air <br /> quality in the Tracy area. Therefore, it appears that the Corral Hollow <br /> Sanitary Landfill may be eligible for inclusion on the National <br /> Priorities List based on the following factors: <br /> 0 Possible soil contamination at depths of over 200 feet; <br /> 0 High groundwater target population; <br /> 0 High waste quantity; and <br /> 0 High air release potential. <br /> 6-2 <br /> sa/tm/chl/si <br />
