Yesterday, the Environmental Protection Agency (EPA) finalized a drinking water standard intended to help protect communities from per- and polyfluoroalkyl substances (PFAS). These “forever chemicals” have been linked to harmful health effects in humans and animals, and the Centers for Disease Control estimates that 99% of Americans have trace PFAS in their bloodstreams. What is less understood though is the levels at which PFAS becomes a threat to human health. In any case, the EPA has moved forward with establishing levels they have deemed safe for public water systems.
In the rule, regulated systems will have three years to complete an initial monitoring and then two years to install treatment technology to help reduce any PFAS levels that are detected above their mandated levels. Regular monitoring is required after that, although the EPA has granted some less-burdensome requirements for small and rural systems (which they define as those servicing 10,000 or fewer people). Below, you can find a fact sheet with more information as it relates to such communities. PFAS has been a noted area of interest for this administration, and a separate rule is expected later this month to protect against companies introducing PFAS into the environment.
