non-hazardous. The decision as to which Closure Alternative to be selected will be based upon the extent of the soil contamination. Closure of the surface impoundments will be followed by a 30 year surface monitoring program. Twenty four monitoring wells have been constructed at this time. Sixteen of the wells are in the shallow portion of the aquifer (50 feet to 70 feet below land surface (bls) ) , three in the intermediate zone (100-110 feet bls) , and five in the lower water-bearing zone (180 to 220 feet bls) . Groundwater levels in the shallow portion of the aquifer ranged from approximately 35 feet bls in April 1986 to 60 feet bls in November 1988. Closure of the surface impoundments will be followed by a 30 year groundwater program. The groundwater beneath the facility is currently being assessed. Depending upon the extent and concentration of contamination the found, a Groundwater Remediation program will be implemented. t if any additional closure activities appear to be needed in order to protect human health and the environment, implementation will be conducted.
