Quick Answer

New York public drinking water is served by 883 EPA-tracked water systems, providing service to approximately 18.3 million residents through public utilities. 5 of those systems currently have open health-based violations on record in the EPA federal database. 313 systems have official PFAS monitoring records from the EPA UCMR 5 program (2023–2025). About 25% of NY residents use private wells, which fall outside federal utility compliance monitoring.

5 New York water systems have open health-based violations recorded in EPA SDWIS. An open violation means a contaminant exceeded a federal limit and the violation has not been formally resolved in the federal database. Check individual utility pages for current status.

Key Contaminant Concerns in New York

These contaminants appear most frequently in New York utility records or pose elevated risk in this region based on EPA data.

high

Lead

Lead is a naturally occurring heavy metal that was widely used in plumbing infrastructure until it was banned for new installations in 1986. An estimated 9.2 million lead service lines still connect homes to public water mains across the United States, along with millions of homes with lead solder in their internal plumbing. Critically, a utility's water quality report can show zero detected lead at the treatment plant while your specific tap still delivers elevated lead — because the contamination happens inside the distribution system and your home's plumbing, not at the source.

EPA limit: 15 ppb (action level)

moderate

Nitrates

Nitrate (NO₃⁻) is a nitrogen-containing compound that forms naturally through the decomposition of organic matter. At elevated concentrations — almost always caused by human activity — nitrate is converted in the digestive system to nitrite, which then reacts with hemoglobin to form methemoglobin, a form of hemoglobin that cannot carry oxygen. In the body, nitrite also reacts with amines in food to form N-nitroso compounds (nitrosamines) — known carcinogens classified by the IARC as Group 2A (probable human carcinogens). The United States applies over 23 million tons of nitrogen fertilizer annually, making agricultural runoff the dominant source of nitrate contamination in U.S. groundwater.

EPA limit: 10 mg/L

moderate

DBPs

When utilities add chlorine to water to kill pathogens, it reacts with dissolved organic matter — leaves, algae, soil — to produce disinfection byproducts (DBPs). Over 600 DBPs have been identified. The EPA regulates two groups: total trihalomethanes (TTHMs, including chloroform) and haloacetic acids (HAA5). DBP levels tend to be highest in surface water systems and in warm months when organic matter is elevated.

EPA limit: 80 µg/L (TTHMs) / 60 µg/L (HAA5)
