Our water system recently violated a drinking water standard for the sum of six per- and polyfluoroalkyl substances (known as PFAS6) and we are taking a number of corrective actions. The drinking water standard is applicable to a lifetime of consuming the impacted water; however, sensitive subgroups, including pregnant or nursing women, infants and people diagnosed by their health care provider to have a compromised immune system, should consider using bottled water that has been tested for PFAS6, for their drinking water, cooking of foods that absorb water (like pasta) and to make infant formula. We are providing an alternative source of water for residents concerned about consuming water with PFAS at the Bluedrop Water Filling Stations available at no cost anytime at the following locations:
This is not an emergency. If it had been, you would have been notified within 24 hours. Although this is not an emergency, as our customer, you have the right to know what happened, what you should do, and what we are doing to correct this situation.
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 or parts per trillion - ppt) for the sum of six per- and polyfluoroalkyl substances (called PFAS6). Our water system proactively and voluntarily sampled for PFAS6 prior to the new regulations. See our latest results in this table.
PFAS6 Results for Randolph/Holbrook Joint Water Plant:
Note: A quarterly average exceeding 20 is a violation of the PFAS6 Maximum Contaminant Level (MCL).
Even though we have been notifying you of our results since we began collecting samples, we must provide you with this Public Notice to comply with the drinking water regulations.
Some people who drink water containing these PFAS in excess of the MCL may experience certain adverse effects. These could include effects on the liver, blood, immune system, thyroid, and fetal development. These PFAS may also elevate the risk of certain cancers.
PFAS6 includes perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), perfluorononanoic acid (PFNA), perfluorohexanesulfonic acid (PFHxS), perfluorodecanoic acid (PFDA) and perfluoroheptanoic acid (PFHpA). PFAS are man-made chemicals that have been used in the manufacturing of certain fire-fighting foams, moisture and stain-resistant products, and other industrial processes.
The Randolph/Holbrook Water Board has taken the following pro-active measures:
