School Water Lead Contamination
New Report Finds Widespread Lead Contamination Across New York School Drinking Water

Environment America gave New York a “C” grade in 2023 for its policies on lead in school drinking water. The group’s senior advocate, David Masur, warned that legal loopholes could leave “hundreds, if not thousands” of contaminated fountains unreported and unaddressed each year.

The 2016 law that established New York’s school lead-testing requirements followed data showing that more than 17,000 New York children under age 6 had elevated blood-lead levels—the highest number reported in any state at the time.

The report found substantial variation within the Capital Region: about half of Albany County schools had at least one outlet above the limit, compared with 10% of schools in Rensselaer County; fewer than 1% of Rensselaer County’s outlets exceeded 5 ppb.

In Broome County, the report’s revised data identified specific schools—including Woodrow Wilson School, Horace Mann, Binghamton High School and Dryden Elementary—as having outlets above the 5-ppb threshold.

Seneca County had the highest share of contaminated outlets statewide, with more than 20% of school water outlets exceeding 5 ppb, even though Jefferson County had the highest percentage of schools with at least one contaminated outlet.
A new report found widespread lead in New York school drinking water, with 42% of school districts reporting at least one contaminated source. Environment America and NYPIRG analyzed testing data from 2023 through 2025 and identified more than 12,000 water outlets exceeding the state's five-parts-per-billion safety limit. Some counties showed alarming rates: Jefferson County had the highest at 84.6% of school buildings affected, followed by Erie and Monroe counties at nearly 70% each.
Health experts say there is no safe level of lead exposure for children. The report highlights gaps in New York's testing rules, which only require schools to test drinking water every three years. Advocates argue these standards allow hundreds of contaminated fountains to go undetected each year. State officials say replacing old fixtures remains the best long-term fix.
How New York's Lead Testing Law Works and Why It May Fall Short
New York enacted lead-testing requirements for schools in 2016 after data showed over 17,000 children under age 6 had elevated blood-lead levels—the highest number in any state at the time. In December 2022, the state lowered its action threshold from 15 ppb to 5 ppb, requiring schools to remove or fix any outlet at or above that level. However, Environment America gave New York a "C" grade in 2023 for its school drinking water policies.
David Masur, senior advocate at Environment America, warned that legal loopholes allow dangerous contamination to escape notice. "Given significant loopholes in the law, hundreds, if not thousands, of drinking fountains contaminated with lead could go unreported," he said. The three-year testing cycle means some outlets may stay contaminated for extended periods before the next round of checks.
Sharp Regional Gaps in Lead Contamination Rates
The report reveals dramatic differences across New York's regions. In the Capital Region, about 50% of Albany County school buildings had at least one outlet above the 5-ppb limit, compared with only 10% in Rensselaer County. Seneca County had the highest share of contaminated individual outlets statewide, with more than 20% exceeding the safety threshold. Newsday reported that more than one-third of Long Island schools had contamination issues.
Specific schools in Broome County were flagged for high lead levels, including Woodrow Wilson School, Horace Mann, Binghamton High School, and Dryden Elementary. Jefferson County topped all counties with 84.6% of school buildings affected, while Chautauqua County followed at 79.4%. On Long Island, 36% of Suffolk County and 33.7% of Nassau County school buildings tested positive for contamination.
Lead Enters Schools Through Aging Pipes and Brass Fittings
New York's municipal water systems typically deliver lead-free water from treatment plants. The problem lies in school buildings themselves. Old plumbing fixtures, brass fittings, and lead-based solder inside aging infrastructure leach toxins into standing water—especially in fountains and taps that sit unused overnight. This is a plumbing problem, not a water supply problem.
Dr. Alister F. Martin, New York City Health Commissioner, defended municipal water quality, saying "There is no better beverage for your health than New York City's clean, fresh drinking water." In response to the report, NYC allocated $5 million to expand water testing and flushing protocols. The city committed to testing contaminated fixtures more frequently and installing filters to capture lead before it reaches students.
Advocates Push for Stricter Standards and Faster Fixes
Health experts and pediatricians stress that no lead exposure level is truly safe for children. Advocates argue that the 5-ppb threshold still allows dangerous contamination (1–5 ppb) to remain active in classrooms. Blair Horner, senior policy advisor at NYPIRG, stated: "New York's schoolchildren have begun another year yet still face the threat of lead exposure. Next year's legislative session must be the year that New York gets the lead out of its schools."
Advocacy groups are demanding state legislation requiring point-of-use lead-capturing filters on all school drinking and cooking taps. Adrienne Esposito, executive director of Citizens Campaign for the Environment, advised interim precautions: "For the schools where they have detected lead, we would encourage parents to have the students bring a reusable water bottle." State officials counter that fixture replacement—not filters—offers the most durable long-term solution, and schools receive state reimbursement for replacements.
