SITE BACKGROUND

The Site is located on 16 acres which were originally surrounded by farmland, but are undergoing rapid development, including a mix of residential, commercial and light industrial areas.  From 1962 to 1981, 15 of the 16 acres were used to produce Styrofoam cups and plates.  In 1981, Continental Refrigerator Corp. bought the property and manufactured refrigerators, freezers and warming cabinets for the institutional food industry.  One acre of the site was leased by Mid-County Mustang since the 1940s, for auto repairs and body shops. Solvents used for engine cleaning were routinely dumped into floor drains until the 1980s when the drains were sealed. From the floor drains, the solvents proceeded onto a drain field and contaminated soil and groundwater, primarily with trichloroethylene (TCE), a major component of solvents and degreasers.  More than 900 people live within one mile of the site, and Valley Creek, a recreational area, is located within a half mile.
