Presentation to the Brevard County Commissioners regarding PFAS chemicals in drinking water

Summary Explanation and Background:
Per- and polyfluoroalkyl substances (PFAS) are a large class of man-made chemicals that have been widely used in industrial processes and consumer products since the mid-20th century. PFAS are valued for their resistance to heat, oil, water, and chemical breakdown; however, these same properties cause them to persist in the environment and accumulate in groundwater and the human body over time. For this reason, PFAS are often referred to as "forever chemicals."
Scientific research over the past two decades has increasingly linked certain PFAS compounds to adverse health outcomes, including impacts on the immune system, thyroid function, cholesterol levels, kidney and testicular cancers, and developmental effects in infants and children. Unlike many other environmental contaminants, PFAS do not readily break down or flush out of the body, and even low-level, long-term exposure, particularly through drinking water, can contribute to cumulative health risk.
PFAS contamination in drinking water most commonly originates from legacy sources such as firefighting foams used at airports and fire training facilities, industrial discharges, landfills, and wastewater treatment processes. Communities with aviation, aerospace, military, and advanced manufacturing activity are statistically more likely to encounter PFAS in groundwater due to historical use patterns. Importantly, PFAS contamination is often the result of past activities and is not necessarily indicative of current practices.
Recent advances in testing technology and epidemiological research have improved the ability to detect PFAS at very low concentrations, measured in parts per trillion (ppt). As scientific under...
