The 57-acre Zellwood site is located in the northwestern corner of Orange County, Florida, situated in a rural area, the site is occupied by four industries and an open field containing a marshy wetland area. Approximately 300 homes within a one-mile radius of the site depend on private wells as their sole source of potable water. Between 1963 and 1971, Drum Service Company of Florida, a drum recycling facility, operated wastewater disposal system without a regulatory permit, treating and disposing of generated wastewaters in two onsite evaporation/percolation ponds. In 1980, the company eliminated the use of these ponds for waste disposal and in August 1981 initiated drainage and removal of contaminated sediments from the ponds. The selected remedial action for the site includes: excavation of soils and sediments with onsite incineration and testing of residuals to determine appropriate disposal; ground water pump and treatment with flushing of the treated ground water back through the abandoned drum area to facilitate cleanup of residual contamination; and a long term ground water monitoring program for private potable water wells. The estimated present worth cost for the remedial action ranges from $41,264,244 to $61,908,244 with estimated present worth O&M of $13,543,244 (excluding ground water treatment and remediation).
