�. <br /> At <br /> jag <br /> L , 2 CONCLUSIONS ANIS RE,COMMENDATIONS <br /> Based on the scope of work performed during this investigation the following conclusions <br /> were developed: <br /> 1. An undetermined amount of waste oil has been allowed to periodically overflow from <br /> the facility's former 200 gallon underground tank. The tank was excavated and <br /> removed in November 1988. The tank was intact and showed only minor signs of <br /> - deterioration. Although the age of the tank is unknown, it is believed to have been <br /> installed before 1970. <br /> 2. The downward leaching of the waste oil spilled from the tank had reached the water <br /> table and had contaminated the groundwater. <br /> 3. The source of the contamination has been eliminated and the majority of the <br /> contaminated soils removed. <br /> 4. Although the areal extent of the groundwater contamination has not been completely <br /> defined, the levels of puigeable halocarbon compounds present in the groundwater . <br /> are well below action levels. The level of groundwater contamination therefore <br /> represents no immediate threat to public health and welfare, and thus require no <br /> 4 further remediation. <br /> 5. Soil samples collected from beneath the base of the in-ground gasoline tank show no <br /> signs of gasoline, EDB or TEL contamination. <br /> Murray & Associates recommends a remedial action program that will include the <br /> monitoring of the levels of groundwater contamination at the site, the removal of the <br /> remaining soil contamination, and the in-place abandonment of the 500 gallon leaded <br /> gasoline tank. Specifically this program should include_ <br /> ,�; 4 <br />
