PFAS

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.
