US EPA Published the Final MCLs for PFAS in Drinking Water

EKI’s PFAS experts, Dr. Corey Carpenter and Dr. Emily Cook, provide fingerprinting forensic assistance and treatment alternatives assessments to our communities and clients to protect public health and meet regulatory goals.

Here is some insight on the final rule requirements:

  • Public water systems must monitor for these PFAS and have three years to complete initial monitoring (by 2027), followed by ongoing compliance monitoring. Water systems must also provide the public with information on the levels of these PFAS in their drinking water beginning in 2027.
  • Public water systems have five years (by 2029) to implement solutions that reduce these PFAS if monitoring shows that drinking water levels exceed these MCLs.
  • Beginning in five years (2029), public water systems that have PFAS in drinking water which violates one or more of these MCLs must take action to reduce levels of these PFAS in their drinking water and must provide notification of the violation to the public.
