PFAS Drinking Water
Per-and Polyfluoroalkyl Substances (PFAS)
Ayer DPW Water Division located in Ayer, Massachusetts has levels of PFAS6 above the Drinking Water Standard
What happened?
Our water system recently received notification of PFAS6 results showing that our system violated the 20 nanograms per liter (ng/L) PFAS6 Maximum Contaminant Level (MCL) drinking water standard during the January – March 2021 compliance period with a quarterly average of 26 ng/L. Samples collected at our Spectacle Pond WTP during this compliance period reported levels of PFAS6 between 23.88 and 28.12 ng/L.
The location where elevated levels of PFAS6 were reported is one of two water treatment plants that supplies drinking water to our system. PFAS6 levels were reported below the 20 ng/L MCL at our Grove Pond WTP, which has treatment for the removal of PFAS6.
