Long Island · PFAS water testing

Test your Long Island water for PFAS.

Long Island sits on a sole-source aquifer, and PFAS “forever chemicals” have been found in water across Nassau and Suffolk. Your utility tests the wellhead — not your tap. Find out what’s actually in your water, analyzed by a lab right here on Long Island.

Why Long Island

Long Island is one of the most closely watched regions in the country for PFAS. Nearly all of its drinking water comes from a federally designated sole-source aquifer beneath Nassau and Suffolk — and once PFAS reach groundwater, they don’t break down.

PFAS have been detected in a number of Long Island public-supply wells, and many water districts have installed or are installing treatment to meet New York’s standards. Common sources include firefighting foam (AFFF) used at airports and military and industrial sites, and legacy industrial plumes. Homes on private wells — common in parts of Suffolk — aren’t covered by any public-system testing at all.

The numbers
  • New York State limit: 10 parts per trillion each for PFOA and PFOS (set 2020)
  • EPA 2024 federal limit: 4 parts per trillion for PFOA and PFOS — a drop in a thousand swimming pools
  • Our panel: 25 PFAS compounds, including PFOA, PFOS, PFHxS, PFBS and GenX
