Farmingdale, NY – Suffolk County Water Authority has closed two wells in East Hampton after finding contamination from toxic PFAS chemicals and has filed a lawsuit alleging a 2023 fire at the East Hampton Energy Storage Center is responsible for the contamination. This Battery Energy Storage System (BESS) was one of the first to be built in New York and is of an older, first-generation model that was put in place before New York implemented strict fire codes. New BESS facilities will be built with state-of-the-art fire mitigation systems that do not require water to be used, this older facility used over 2 million gallons of water to fight the fire and had no containment system to prevent contamination from seeping into Long Island’s groundwater.

Citizens Campaign for the Environment is urging East Hampton Energy Storage Center to take responsibility and clean up the contamination. CCE is also urging New York State and municipalities to require that new facilities implement stormwater management to prevent PFAS or other contaminates from entering groundwater. While the situation in the East Hampton fire would be prevented by the New York State fire codes, developers should still be implementing a system to ensure there is no potential PFAS in stormwater runoff from rain.

Adrienne Esposito, Executive Director, Citizens Campaign for the Environment, issued the following statement:

“Battery Energy Storage Systems are a critical piece of our renewable energy mix and necessary to diversify our energy sources. They stabilize our energy grid in the face of more extreme weather events and provide capacity that will reduce our reliance on fossil fuels, leading to cleaner air for New Yorkers. Every large-scale energy project has impacts, but especially with newer technology such as BESS, it is crucial that we build them responsibly and in a way that is protective of our environment.  

The East Hampton Energy Storage Center was one of the first BESS projects in the state.  The fire helped spur New York to create a stringent, protective fire code to ensure these systems are built safely with no risk to the community. PFAS contamination was a result of using the sprinkler system designed to fight such a fire if one occurred, therefore, the company is at fault and we are calling on the developer to fully clean up that contamination. Moving forward, we need to ensure that no toxic contamination results from stormwater runoff at BESS facilities. We must protect drinking water and communities. We must also transition off fossil fuels by building renewable energy and energy storage. This can absolutely be done safely and responsibly.”

They’re Everywhere So-called ‘forever chemicals’ are hazardous, potent and ubiquitous

They’re Everywhere So-called ‘forever chemicals’ are hazardous, potent and ubiquitous

This is a tale about unintended consequences in science, governmental malfunction affecting Suffolk County, and a mammoth spread, globally, of poison.

It began in 1938. As the website Health Brief related last week: “A chemist at the DuPont company accidentally discovered an exciting new polymer. It repelled water, it was chemically stable and nonreactive, and nothing stuck to it. The material — brand name: Teflon — has been used in countless consumer products since then to reduce friction between surfaces. Among its best-known applications is in nonstick cookware. … In the past few decades, however, the chemicals that go into nonstick surfaces have been linked to certain health issues and environmental pollution.”

The Navy is wrong to let Calverton become Bethpage

The Navy is wrong to let Calverton become Bethpage

Suffolk County Executive Edward P. Romaine fired a shot across the U.S. Navy's bow last week.

At a community meeting in Calverton, Romaine threatened to sue because two toxic plumes at the former Naval Weapons Industrial Reserve Plant are spreading forever chemicals, or PFAS, and endangering the region's water. The Navy has delayed cleanup, Romaine said.

Brookhaven plume cleanup plan calls for more water hookups, monitoring: A look at the options

Brookhaven's plan to clean up a 4-mile-long toxic plume that runs through residential neighborhoods south of the landfill calls for hooking up more homes to public water systems and expanding a drinking water monitoring program — but closing the landfill still would have to wait two more years.

Suffolk County officials are pointing to the Navy’s cleanup of the Bethpage plume as a precedent — and warning they expect the same urgency in Calverton, where county testing shows contamination from the former Navy-owned Grumman manufacturing site continues to move through groundwater, surface water and fish habitat while federal cleanup efforts remain largely in the study phase.

Suffolk County Pushes Navy to Clean Up EPCAL Plumes

Suffolk County says it has compiled mountains of ammunition in its fight to get the U.S. Navy to clean up plumes of numerous hazardous compounds emanating from the Enterprise Park at Calverton, including data showing fish highly contaminated with the perfluorinated compound PFOS the county says the Navy withheld for a year, and high levels of other perfluorinated compounds in the headwaters of the Peconic River.

After the U.S. Navy refused to allow the Suffolk County Health Department to present the results of its testing of wells surrounding plumes of contaminated groundwater from the former Navy-owned Grumman plant in Calverton at the February meeting of the Calverton Restoration Advisory Board (RAB), county representatives and members of the RAB took matters into their own hands Tuesday evening.

Years of independent ground and surface water testing by Suffolk County shows that a far more extensive plume of industrial chemicals is spreading beyond the former Grumman site in Calverton than the U.S. Navy has acknowledged. 

EPA cannot backtrack on PFAS drinking water standards

EPA cannot backtrack on PFAS drinking water standards

This guest essay reflects the views of Adrienne Esposito, the executive director of Citizens Campaign for the Environment, an advocacy organization based on Long Island.

I've spent decades fighting water contamination on Long Island. I've sat with families who found PFAS in their well water and helped communities and water districts scramble to obtain funding for expensive treatment systems. I've testified for congressional hearings to increase the understanding that PFAS, commonly called "forever chemicals," aren't a hypothetical threat — they are a daily, sickening reality for millions of Americans.

LIPA, labor and environmental groups highlight strong first year for South Fork wind

Officials say that reliability proved especially important during this winter’s cold snaps, when energy demand surged and fossil‑fuel prices spiked.

The South Fork Wind project is marking its first full year of operation, and new data released this week shows the nation’s first utility‑scale offshore wind farm is performing even better than expected. Leaders from LIPA, labor unions, environmental groups and the offshore wind industry gathered on Long Island to highlight the results, which show the 12‑turbine project generated electricity on 99% of days last year and reached a 50% capacity factor—a level comparable to traditional power plants during key demand periods.

Brookhaven Presents Cleanup Plan for Landfill Plume, but Some Say Measures are Inadequate

Brookhaven Presents Cleanup Plan for Landfill Plume, but Some Say Measures are Inadequate

The Town of Brookhaven held a public meeting on March 27 to present its corrective measures plan for a toxic plume emanating from the town landfill in Yaphank, but community advocates say the proposal falls far short of what’s needed. 

In 2023, the New York State Department of Environmental Conservation ordered the town to investigate and plan to remediate the plume, which now extends 1.7 miles from the portions of the landfill constructed between 1971 and 1989 south toward Bellport Bay. Groundwater testing detected PFAS (so-called “forever chemicals”) and 1,4-dioxane in the plume. Both contaminants have been linked to a range of health issues, including cancer.
