The U.S. Navy is looking to sample private drinking water wells in designated areas near the former Naval Weapons Industrial Reserve Plant/Grumman facility in Calverton to test for the presence of PFAs — per-fluoroalkyl and poly-fluoroalkyl substances, which have been detected in portions of the groundwater in the area.

These substances may be present in the soil and/or groundwater at Navy sites as a result of historical firefighting activities using aqueous film forming foam, including response to crashes, equipment testing and training, according to a fact sheet issued by the Navy.

The Navy is inviting the public to an informational open house at the Residence Inn on Route 58 Tuesday evening from 4 to 7 p.m. Representatives of the Navy, the U.S. Environmental Protection Agency, the N.Y. State DEC and health department and the county health department will be on hand to discuss the situation and the plans for sampling private wells in the designated areas.

The water testing will be completed at no cost to the homeowner.

Drinking water provided by Riverhead Water District has been tested and PFAs were not detected, according to the Navy fact sheet. Therefore, sampling of properties receiving water supplied by the Riverhead Water District is not necessary, the Navy said.

Although available records indicate the majority of drinking water in the designated areas is supplied by the Riverhead Water District, the Navy has identified several private drinking water wells. (See “Calverton Fact Sheet, figure two, below). We are seeking the public’s assistance to identify any additional drinking water wells located in the shaded areas depicted.

For more information visit the Naval Facilities Engineering Command webpage about PFAs.
