The 32-acre Alpha Chemical Corporation site is located in Kathleen, Florida. It includes an area where various manufacturers have produced fiberglass material since 1967. EPA placed the site on the Superfund Program’s National Priorities List (NPL) in 1983 because of contaminated soil and groundwater resulting from manufacturing operations.

EPA, the Florida Department of Environmental Protection (FDEP) and Alpha Resins Corporation (ARC), the site’s potentially responsible party (PRP), have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination.

Groundwater sampling at the site has consistently shown that site contaminants of concern (COCs) are below Maximum Contaminant Levels (MCLs). The COCs are Ethylbenzene, Styrene, Xylene, 1,2 Dichloropropane and Benzoic Acid. In addition, surface water sampling was discontinued in 1994 due to site COCs concentrations remaining below these MCLs and Ambient Criteria for Fresh Water Life. Lastly, all 2013 soil sampling results from underneath the liner of the capped pond indicated COC concentrations below FDEP Soil Clean-up Target Levels. In 2014, EPA HQ and FDEP discontinued the requirement to conduct Five Year Reviews as the site had met the requirements for unlimited use/unrestricted exposure (UU/UE) and is protective of human health and the environment.
