Water Quality Testing on Long Island
Long Island has one of the most vulnerable drinking water supplies in the country. PFAS, 1,4-dioxane, agricultural runoff, and aging infrastructure have affected both private wells and municipal supplies across Nassau and Suffolk counties.
We provide professional water testing for homes across Nassau County, Suffolk County, Long Island, Manhattan, Brooklyn, Queens, the Bronx, and Staten Island.
What We Test For
- Bacteria and coliform — E. coli and total coliform contamination
- Lead and copper — leached from older pipes, fixtures, and solder joints
- Nitrates and nitrites — agricultural runoff, especially Suffolk County
- VOCs — industrial solvents and dry-cleaning chemicals
- PFAS / PFOA / PFOS — "forever chemicals" documented in Long Island groundwater
- 1,4-Dioxane — Nassau/Suffolk-specific contamination concern
- pH, hardness, and iron — water quality characteristics
- Radon in water — critical for private well users
Private Well Users — Annual Testing Required
If your home uses a private well, there's no municipal treatment protecting you. Contaminants change seasonally. We recommend testing at every home purchase and annually for all well users.
