DUDLEY – The town is about to notify more than 2,300 water system users that their water contains chemicals called PFAS6 at levels deemed unsafe to drink.
Dudley is not the first water supplier mandated to send such a notice and won’t be the last as the state Department of Environmental Protection preps for a wave of similar occurrences statewide before the year is out.
The DEP changed its public drinking water regulations for six chemicals in October by lowering the maximum allowable amount from 70 parts per trillion to 20 ppt.
According to DEP records, among the public water systems that have already been found to be serving water above the 20 ppt standard are the Aquarion Water Co. in Millbury, the Hudson Water Supply and the Princeton Town Campus.
These six Per- and Polyfluoroalkyl substances, known as PFAS6, are synthetic chemicals found in consumer products, such as cookware, pizza boxes, stain repellents and firefighting foam.
According to the DEP, some people who consume PFAS6 above 20 ppt may experience adverse effects on the liver, blood, immune system, thyroid, and fetal development. PFAS6 consumption could also elevate the risk of certain cancers.
Pregnant or nursing women, infants and people diagnosed as immunocompromised are considered a “sensitive subgroup.” These people are at greater risk and are advised by the DEP not to drink or cook with the water.
