Applied Ecology presented the results of a recent study performed for Satellite Beach at their City Council Meeting. As part of an investigation into potential concerns regarding Per- and Polyfluoroalkyl Substances (PFAS), the City of Satellite Beach contracted Applied Ecology, Inc. to sample and analyze groundwater samples in nine distinct locations (three groundwater monitoring wells, five irrigation wells, and one beach access shower) throughout the City for PFAS. While there are numerous PFAS compounds, two tested under this study (PFOS and PFOA) have been identified as having potential human health and/or environmental impacts. The results from the all nine locations had concentration values of PFOS, PFOA, and combined PFAS below U.S. Environmental Protection Agency (USEPA) lifetime drinking water health-advisory (HAL) of 0.07 μg/L as well as the Provisional Irrigation Water Screening Levels (IWSLs) for PFOA and PFAS (6.7 μg/L and 72 μg/L, respectively) of developed by the Florida Department of Environmental Protection (FDEP) through the University of Florida (UF) Center for Environment & Human Toxicology.
Additionally, a full suite of federally listed priority pollutants, carcinogens, volatile and semi-volatile organics, pesticides, herbicides, perchlorate, and radionuclides were sampled in the three shallow groundwater monitoring wells as a response to the community’s concerns about local cancer rates. Results for this expanded sampling were compared to all available standards, including Florida’s Groundwater Cleanup Targets (GCTLs) and IWSLs for the appropriate constituent of concern (COCs). Overall, concentrations for the extensive list of COCs, including volatile and semi-volatile organics, pesticides, herbicides, heavy metals, perchlorate and radionuclides were either non-detectable or well below the appropriate screening values.
