Where to get it tested

Three routes, and all of them work. A mail-in kit from a certified lab is the simplest: the lab ships bottles, you fill them at the kitchen tap, and results come back by email. The full panel above is $209.

A local certified lab is the second route. Environmental Laboratory Approval Program from NYSDOH lists every lab certified for drinking water in New York. Call ahead: some take walk-in samples, some ship bottles.

Free or low-cost testing: The NYS Department of Health's Private Well PFAS Testing and Mitigation Rebate Pilot Program offers free PFAS testing, and rebates for PFAS treatment, to private well users in Dutchess, Orange, Putnam, Suffolk, Ulster, and Westchester counties while funds last.

Common questions

What should I test my well for in New York?

Start with PFOA, PFOS, nitrate. 60% of 154 local samples were above the limit. Add total coliform bacteria and nitrate every year for any private well.

Where can I get my well water tested in New York?

Use a lab certified for drinking water. NYSDOH keeps the list of certified labs. A mail-in kit from a certified lab works anywhere in the state.

How much does well water testing cost in New York?

A full mail-in panel from a certified lab costs $209 (Tap Score well water test kit). A bacteria-only test costs $99 (Tap Score coliform and E. coli test).

Is there free well water testing in New York?

The NYS Department of Health's Private Well PFAS Testing and Mitigation Rebate Pilot Program offers free PFAS testing, and rebates for PFAS treatment, to private well users in Dutchess, Orange, Putnam, Suffolk, Ulster, and Westchester counties while funds last.

How often should a private well be tested?

Bacteria and nitrate every year. A full panel once, then again after flooding, a change in taste, smell or color, work on the well, a new baby in the house, or a nearby result above the limit. Contaminants that come from the rock, like arsenic, radon and uranium, change slowly, so one good test and a check every few years is enough.
