On Dec. 2, 2019 the Ohio Environmental Protection Agency (Ohio EPA) and Ohio Department of Health (ODH) released a statewide action plan to analyze the prevalence of per- and polyfluoroalkyl substances (PFAS) in Ohio’s drinking water.
Under the plan, Ohio EPA coordinated testing for close to 1,550 community and non-transient non-community public water systems for six PFAS chemicals: PFOA, PFOS, GenX, PFBS, PFHxS, and PFNA.
There are currently no national drinking water standards for PFAS compounds. The establishment of national drinking water standards, called Maximum Contaminant Levels or MCLs, is under consideration by United States Environmental Protection Agency (U.S. EPA). In 2016, U.S. EPA set Health Advisory Levels (HALs) of 70 parts per trillion (ppt) for PFOA and PFOS. In 2019, Ohio’s action plan included the use of these HALs for PFOA and PFOS and established action levels for four additional chemicals in the PFAS family, including GenX, PFBS, PFHxS, and PFNA.
