PFAS

The new lifetime health advisory levels are lower than the maximum levels set by New York State in 2020 and lower than what can currently be detected by testing technologies.

Riverhead is seeking grant funding from New York State to help the Riverhead Water District provide public water to an area of Calverton near the terminus of the Long Island Expressway where health-threatening contaminants have been identified in private drinking water wells.

Chemical contaminants known to have a wide range of health risks have been detected at the Riverhead landfill site on Youngs Avenue at levels up to more than 10 times the state drinking water standard, prompting an investigation by environmental and health officials into potential contamination of nearby private wells.

The Navy is quietly conducting a survey to measure the community's 'environmental concerns' about the former Grumman site in Calverton. A Navy rep said lack of community interest may mean a 23-year-old community advisory board should be shut down.

Navy representatives will discuss their investigation into groundwater contamination on and near the former Grumman manufacturing facility in Calverton during a virtual meeting of the Calverton restoration advisory board Thursday, April 29 at 7 p.m.

Local residents, environmental advocates and officials are “united” in their demand for the U.S. Navy to pay the cost of bringing public water to homes near the the former Grumman Aerospace manufacturing plant in Calverton. The Navy, however, is unimpressed.

Data released by the Navy this week for the first time show significant detections of toxic PFAS chemicals at the southern border of the former aerospace manufacturing site.

After finding per- and polyfluoroalkyl substances (PFAS) at the former Grumman site in Calverton, the Navy will conduct further testing, over the next two years, to determine the extent of PFAS groundwater contamination there.

Naval environmental engineers say there is no need to expand sampling area or provide alternative water supply to area around former Grumman facility, despite PFAS contamination.
