At a glance

Water test for a new wellNot required statewide

No single statewide rule. The driller must be DEC-registered, file a preliminary notice before drilling, disinfect the finished well under NYSDOH Appendix 5-B, and send a well completion report to DEC and to you within 30 days. NYSDOH says a new well should be tested before use for coliform bacteria, nitrate, nitrite, arsenic, lead, iron, manganese, sodium, hardness, pH and turbidity. Many county health departments (Westchester, Rockland, Putnam, Dutchess, Suffolk and others) require a permit and a passing water test before a new well can be used.

Water test when a home is soldNot required statewide

No statewide requirement. A few counties and towns require a well test or well inspection when a property changes hands, and FHA, VA and USDA loans usually ask for a bacteria and nitrate test. Check with the county health department.

What the state recommends

NYSDOH recommends a coliform bacteria test every year, plus a first-time panel of nitrate, nitrite, arsenic, lead, iron, manganese, sodium, sulfate, hardness, pH, alkalinity and turbidity, then periodic re-testing of whatever showed up. Add radon, uranium, methane or PFAS where they are known in your area.

Free or low-cost testingAvailable

No statewide free program. Several county health departments run their own ELAP-certified labs and sell low-cost bacteria and nitrate tests (Erie, Monroe, Suffolk, Nassau, Cattaraugus, Chautauqua, Allegany). Others keep a list of local certified labs.
