Perfluorinated Chemicals in Our Drinking Water

Long Island's water supply at risk

Emerging contaminants like Perfluorinated Chemicals (PFCs) present a new threat to our drinking water supply. Unfortunately, there is no set standard for these synthetic manufacturing chemicals that are widespread and have been found in bloodstreams of humans, wildlife and fish, and are considered by the US EPA to be a likely human carcinogen. We all know that Long Island’s sole source aquifer is already at risk, but with each passing day, it seems like the threats to Long Island’s waters just keeps rising.

In 2016, the US Environmental Protection Agency first confirmed unregulated PFCs in the local drinking water wells near the Westhampton Air Base. In August 2017, NYS Department of Environmental Conservation launched its own investigation into the source of PFC pollution responsible for contaminating more than 100 private wells near an airport in Westhampton. These investigations led researchers to suspect that the source of the PFCs was related to a firefighting foam used at the nearby air base for decades and had polluted residents’ drinking water. 

But the problem doesn’t end in Westhampton…

After a sustained investigation, The Suffolk County Health Department is now expanding its own survey of private wells near the East Hampton Airport and a former sand mine after the discovery of PFCs in contaminated wells went from 59 to 63 in the nearby hamlet of Wainscott. PFCs are also now showing up in the hamlet East Quogue at a former town brush dump with significant potential consequences for local homeowners with private wells. 

So, what’s the concern? Unfortunately, EPA’s current lifetime health advisory level for PFCs is only .07 parts per billion, yet PFC concentrations in some private wells have been found to be more than 100 times greater. In addition to locating the sources of contamination, further studies are now being conducted to better determine the health effects of PFCs, with some researchers finding links between the chemicals and behavioral disorders, neurobehavioral development, and immune function.

Long Island needs strong protection by government at both the local and State levels to protect our drinking water. You can help us deliver this message!  Tell your legislators to take a stand for clean water by protecting the clean water we have, cleaning up our polluted drinking water, and investing in the long-term health of our coastal bays and harbors.
