State Department of Health to Issue Proposed Regulations for PFAS in Drinking Water Systems. Are you ready?

Do you have a PFAS problem? What is your risk? The professional environmental engineers and geologists at C.T. Male Associates have proven experience and leadership in PFAS investigation, corrective action, and fund development. We continue to review the evolving science around health risks associated with PFAS, closely following efforts by the USEPA and states, and updates are everchanging.  We’re here to help our clients manage through these changing regulations.

The Latest Update and what it means: NYS Drinking Water Regulations (October 4, 2022) – the NYSDOH proposed to adopt individual MCLs of 10 ppt for four (4) additional PFAS compounds (perfluorodecanoic acid (PFDA), perfluoroheptanoic acid (PFHpA), perfluorohexane sulfonic acid (PFHxS), and perfluorononanoic Acid (PFNA)) and includes a combined MCL of 30 ppt for PFDA, PFHpA, PFHxS, PFNA, perfluorooctanic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), referred to collectively as perfluoroalkyl substances-6 (PFAS6). The proposed rule also establishes the first list of emerging contaminants (ECs) as well as notification levels for this list of ECs in accordance with Public Health Law § 1112.

This proposed regulation applies to all community water systems and all non-transient noncommunity water systems and has entered into the public comment period.  The PWS will be required to routinely monitor for PFNA, PFDA, PFHxS and PFHpA. Initial monitoring for PFAS6 compounds must be completed by December 31, 2023 and each PWS will be required to comply with the MCL by January 1, 2025. This proposal also modifies the analytical requirements by mandating reporting all compounds in EPA 537.1 or EPA 533.
