PFAS (per- and polyfluoroalkyl substances) Information
Recent PFAS6 results for samples collected from the interconnection / entry point locations where the North Attleborough water enters the Plainville Public Water System at Kelly Boulevard were above the MCL; however, the Everett Street entry point result was below the MCL at the time the sample was collected. Because the North Attleboro Water Department results are above the MCL at the McKeon Water Treatment Facility, we must provide you with this Public Notice. Additionally, we are required to sample our own sources, and the results from the Turnpike Wells are below the MCL.
The Plainville Water Department is providing this public notice (PDF) because our water system is considered a consecutive System to the North Attleborough Water System which recently violated a newly promulgated drinking water standard for PFAS6.
On October 2, 2020, the Massachusetts Department of Environmental Protection (MassDEP) promulgated a new drinking water regulation and Maximum Contaminant Level (MCL) of 20 nanograms per liter (ng/L) for the sum of six per- and polyfluoroalkyl substances (called "PFAS6").
The North Attleboro Water Department has confirmed elevated levels of PFAS6 above the 20 ng/L MCL in the McKeon Water Treatment Facility (WTF), one of its drinking water sources, during routine PFAS6 monitoring. Visit the Town of North Attleborough's Water System Public Notice.
