NPL Site Narrative for Stauffer Chemical Co. (Tampa Plant)
STAUFFER CHEMICAL CO. (TAMPA PLANT)
Tampa, Florida
Federal Register Notice: February 7, 1992Stauffer Chemical Co. formulated pesticides adjacent to the Tampa Bypass Canal at 2009 Orient Road in Tampa, Hillsborough County, Florida, between 1951 and 1986. The site covers 40 acres in an industrial area. Currently, Imperial Chemical Industries owns the facility; in the past, it has been owned by Cheeseborough Ponds, Inc., and Unilever.
Stauffer Chemical received bulk shipments of agricultural chemicals, which it then formulated into insecticides and herbicides in the forms of dusts, grains, and liquids for packaged distribution. Between 1953 and 1973, various portions of the property were used as disposal areas, among them: 1) the "Barren Area," a large area of soil apparently contaminated through runoff from a storage/disposal area; 2) an area where 8,000 to 10,000 gallons of toxaphene, which had leaked from a tank car, were buried; and 3) an area of contaminated soil where an incinerator once operated.
EPA investigations conducted in 1987-88 documented contamination in on-site soils, sediments, ground water, and air. Contaminants included 4,4'-DDT, 4,4'-DDD, 4,4'-DDE, lindane, and alpha-BHC. The formations underlying the site are 1) the unconfined surficial aquifer consisting of interbedded sands, clays, and shells that are approximately 25 feet thick; and (2) the Upper Floridan Aquifer consisting of the Tampa Limestone, Suwanee Limestone, Ocala Group, and the Avon Park Limestone. Public and private wells within 4 miles of the site provide drinking water to an estimated 6,700 people. The nearest well is a private well 0.24 mile northwest of the site. Approximately 113,000 persons work, attend school, and/or reside within 4 miles of the facility.
