New York Schools Expand Water Testing and Flushing to Reduce Lead Exposure
A $5 million initial city investment will increase monitoring at affected faucets and add protections in public schools, health and education officials say.

NEW YORK — New York City health and school officials are expanding protections against lead in public-school drinking water, backed by an initial $5 million city investment announced Sept. 17. The plan increases testing and flushing and calls for additional action at faucets where elevated readings recur. Officials said the source of risk is generally building plumbing, not the water arriving from the city's upstate reservoir system.
Under the new approach, schools with faucet readings above New York state's 5-parts-per-billion action level will test affected locations at least annually instead of once every three years and replace the fixture, according to the Health Department and New York City Public Schools. The agencies said they will increase flushing and take further steps to protect drinking water. Five parts per billion is an action threshold for intervention, not a declaration that any exposure below it is harmless.
The announcement follows concerns raised by the New York Public Interest Research Group about recurring problems at individual outlets. City officials said existing detection and remediation have worked in most schools but that some faucets can show renewed elevated readings. More frequent tests may reveal additional problem fixtures; the measure of the program will be how promptly those fixtures are fixed and how clearly results are communicated to families.
The Health Department said the number of city children under six with blood lead levels of at least 3.5 micrograms per deciliter fell 94% between 2005 and 2025. That broad progress does not remove the need to address a specific contaminated outlet. Families seeking details about their school should rely on published test results and school communications rather than assuming a citywide trend describes every drinking fountain.
