Waste Site Cleanup State Funded PFAS Sampling Efforts

The Florida Department of Environmental Protection’s (DEP) Waste Cleanup Program conducted a statewide survey of thirty-eight (38) waste cleanup sites that are undergoing state funded cleanup.  The purpose of this survey was to gather information regarding whether Per-and polyfluoroalkyl substances (PFAS) could be a contaminant of concern at these facilities.  These facilities range from former landfills, metal plating facilities, chemical manufactures, electroplaters, and users of various solvents. 

The most common and well-studied PFAS are Perfluorooctanoic acid (PFOA) and Perfluorooctane sulfonic acid (PFOS).  PFOA and PFOS are man-made chemicals that do not occur naturally in the environment.  They have been used in a variety of commercial products since the 1940s, including stain and water repellents used in textile manufacturing and fire suppression foams. 

DEP has calculated provisional Groundwater Cleanup Target Levels (P-GCTLs) for PFOA and PFOS.  The calculations were completed in accordance with Chapter 62-777, Florida Administrative Code (F.A.C.), equations and methodology.  The P-GCTLs for PFOA and PFOS concentrations are 70 nanograms per liter (ng/l), and 70 ng/l for the sum of PFOA and PFOS concentrations. 

The below figure shows the location of the thirty-eight (38) State funded sites that were sampled or will be sampled and the initial sampling results.

Where contamination has been identified above the DEP P-GCTL, DEP has coordinated with the Florida Department of Health to determine if there are nearby water supply wells and conduct sampling of water drinking wells, where necessary, to ensure protection of human health.  The Waste Cleanup Program continues to assess the State funded cleanup sites that had contamination above the P-GCTLs to determine the probable source of contamination, evaluate the environmental impacts, and develop cleanup plans to reduce the potential risk of exposure to human health and the environment. 

DEP is committed to providing timely information to the public regarding these efforts. This web page will be dedicated to making this information readily available and accessible to the public.  

The below list includes the sites that were above P-GCTLs.  To review additional information on these sites, please search the DEP Nexus Information Portal using the ERIC ID number provided below.
