NH PFAS FAQs

Throughout the northeast and across the nation, state and local officials, health departments, and water utilities including Aquarion have focused their attention on a group of man-made chemicals called per- and polyfluoroalkyl substances (PFAS) that have been detected in drinking waters, including public and private water supplies, and bottled water. Some health officials indicate that consumer products, food, and cookware represent the largest exposure of PFAS to people. However, drinking water contaminated with PFAS can also be a source of exposure.

Aquarion has been and will remain vigilant about this important issue, and will continue additional PFAS testing beyond compliance testing at some of our water sources. We will continue to share test results with our customers and state and local officials. We will also continue to work with the public health agencies and drinking water associations to ensure protection of our drinking water supplies, and delivery of high quality water to our customers.

Below are Aquarion’s latest sampling results and additional information on PFAS.

EPA PFAS Proposed Regulation

On March 15, 2023 the US EPA proposed a National Primary Drinking Water Regulation (NPDWR) for 6 of the following PFAS Compounds: Perfluorooctanoic acid (PFOA), Perfluorooctane sulfonic acid (PFOS), Perfluorononoctanoic acid (PFNA), Perfluorohexane sulfonic acid (PFHxS), Perfluorobutane sulfonic acid (PFBS), and Hexafluoropropylene oxide dimer acid (HFPO-DA, aka GenX Chemicals). Aquarion is continuing our compliance PFAS testing program in each of our water systems to ensure our customers receive the highest quality water achievable. This proposed rule does not require action until it is finalized at the end of 2023, however, Aquarion will proactively be working to meet the proposed NPDWR.

Below are the proposed Maximum Contaminant Levels (MCLs):

  • PFOA – 4 ppt*
  • PFOS – 4 ppt*
  • PFNA, PFHxS, PFBS, and HFPO-DA – 1.0 Hazard Index (unitless)

* ppt – parts per trillion
