PFAS Litigation

Per- and polyfluoroalkyl substances (PFAS) are man-made compounds that have been widely used in the manufacturing of clothing, sealants and stains, furniture fabrics, Teflon™-coated products, food packaging, and other materials since the 1940s. They are also used in industrial processes. The U.S. Environmental Protection Agency (EPA) is focused on a small number of these compounds that may have health effects at very low concentrations, two of which are perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS).

It is not uncommon to find low levels of PFAS in drinking water sources as they are slow to break down when they enter our environment. When products containing PFAS are used and discarded, or manufacturers and industrial users dispose of waste, they can release PFAS into the environment, including drinking water sources.

In 2020, Tampa Bay Water joined a lawsuit against manufacturers, sellers and distributors of PFAS to protect its member utilities and Tampa Bay residents from the potential financial impacts of removing PFAS from the drinking water sources and system.

In July 2025, Tampa Bay Water’s litigation firm, Ventura Law, announced ninety percent of the settlement has been decided and totals $21.7 million for Tampa Bay Water. Read the news release.

An important step was for litigation experts to test the region’s drinking water sources to determine if there are any detectible levels of PFAS. The sampling is complete and litigation experts found detectible levels of PFAS in and around some of the regional sources of drinking water.

Finding detectible levels of PFAS shows that Tampa Bay Water has a case for pursuing this lawsuit and having the polluters bear the cost of treatment – not the member governments or the rate payers. It’s important to note that the levels detected, while supporting the case against the polluters, are close to EPA's regulatory limits for PFOA and PFOS of 4 parts per trillion (ppt).
