Water quality

New York water quality

New York drinking water is regulated by the New York State Department of Health (DOH) and generally meets federal standards, and the state was among the first to set its own enforceable PFAS limits. According to DOH and NYSDEC, PFAS contamination has affected communities including Hoosick Falls and Newburgh, and the state has estimated a significant share of public water wells need PFAS treatment. Aging infrastructure with legacy lead pipes is a documented concern in older cities.

Documented considerations

PFAS

According to DOH and NYSDEC, PFOA was found in Hoosick Falls' water above the former federal advisory level, and PFOS from firefighting foam at Stewart Air National Guard Base contaminated Newburgh's supply. New York set enforceable PFOA and PFOS standards in 2020.

Lead

New York's aging water infrastructure includes many legacy lead service lines and lead plumbing, particularly in older cities, which can leach lead into tap water.

Disinfection byproducts

Surface-water systems in New York can report total trihalomethanes from chlorination, as reflected in DOH and EWG data.

Hardness

Hardness varies across New York: parts of the Hudson Valley and limestone-influenced regions report moderate hardness, while other systems are softer.

EPA compliance snapshot

From the EPA ECHO Safe Drinking Water Act database, New York community water systems carrying one or more violations on record:

880
systems with a violation on record
6
with a health-based violation
1
flagged serious violators

Most common violation categories

  • Revised Total Coliform Rule (538)
  • Nitrate (211)
  • Lead and Copper Rule (63)
  • Total Haloacetic Acids (HAA5) (38)
  • TTHM (38)
  • Benzene (26)

Counts are public EPA ECHO figures. 'Health-based' means a system carries at least one health-based violation flag in ECHO. A violation on record is not a statement that current tap water is unsafe; most systems return to compliance. Always check your utility's Consumer Confidence Report for current status.

FAQ

Why is PFAS a big issue in New York?
According to DOH and NYSDEC, New York has been an epicenter of PFAS drinking water contamination, with notable cases in Hoosick Falls (PFOA from manufacturing) and Newburgh (PFOS from firefighting foam at a military base). The state set enforceable PFOA and PFOS limits in 2020.
Does New York have lead pipes in its water systems?
Yes. New York's aging infrastructure includes many legacy lead service lines and lead plumbing, especially in older cities, which can contribute lead at the tap. Because lead is particularly harmful to children, checking your service-line material and using lead-certified filtration are reasonable precautions.
Is New York tap water safe to drink?
Most New York public water systems meet EPA and DOH standards, and the state has strong PFAS regulations. Documented concerns include PFAS in certain communities and lead from older plumbing, so reviewing your local water-quality report is the best way to understand your specific water.
