Elevated Levels Of PFAS Found In Some Wells At Ninigret Park

Charlestown has been notified by the the Army Corps of Engineers that elevated levels of PFAS (per- and polyfluoroalkyl substances) have been found in some of the wells at Ninigret Park. The wells are not used for drinking water.

Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been manufactured and used in a variety of industries around the globe, including in the United States since the 1940s. PFOA and PFOS have been the most extensively produced and studied of these chemicals. Both chemicals are very persistent in the environment and in the human body – meaning they don’t break down and they can accumulate over time. There is evidence that exposure to PFAS can lead to adverse human health effects.

The Army Corps testing of well water is part of their ongoing monitoring of the former U.S. Navy landing site at Ninigret Park. The wells where PFAS were found are not used for drinking water, but out of an abundance of caution to make sure the water is not used for drinking, signs have been posted at the bathrooms near Little Nini Pond to notify people not to use the water from the sinks to drink.

The Army Corps will continue to conduct additional, expanded testing of these wells. The Town of Charlestown is relying on the Army Corps of Engineers to resolve this issue. The town has promised to update the community as new information becomes available.

Information about PFAS is available from the EPA and the Agency for Toxic Substances and Disease Registry. The Town of Charlestown prepared the fact sheet below about PFAS in cooperation with the RI Department of Health to help answer questions.
