Frequently Asked Questions

What should I test my well water for in New York?

NYSDOH recommends testing annually for coliform bacteria and nitrates at minimum. Given regional contamination history, also test for: PFAS (including PFOA and PFOS where plumes are known), 1,4-dioxane, and (especially on Long Island) saltwater intrusion and legacy industrial solvents, lead, arsenic, volatile organic compounds (VOCs), iron, manganese, and pH. Check with NYSDOH or NYSDEC for contaminants of concern in your region.

How often should well water be tested in New York?

Test annually for bacteria and nitrates. Comprehensive testing every 2-3 years is recommended. Test immediately after any flooding event, if you notice changes in taste, odor, or color, or if you receive a notice about contamination in your area from local authorities.

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

Use a state-certified laboratory. Your local board of health, state university cooperative extension office, or environmental watch program can provide sampling kits and recommend certified labs. Some well service companies also partner with certified labs.

How much does well water testing cost in New York?

Basic bacterial and nitrate testing costs $75-$150. A standard potable water panel (bacteria, nitrates, pH, iron, manganese, hardness) costs $150-$300. Extended testing for specific contaminants adds $150-$300 per sample. A comprehensive panel including multiple contaminant types costs $400-$700.
