Search Long Island schools' lead test results

Every school district in New York is required to test water fixtures in its schools for lead, a neurotoxin that is especially dangerous for children. For this most recent round of tests, conducted between 2023 and 2025, the state limit for lead was lowered from 15 parts per billion to 5, following increasing evidence that exposure to even very small amounts is harmful. Any fixture that doesn’t meet the state limit of 5 parts per billion must be replaced, repaired, or shut off.

Nearly 3,000 fixtures across Long Island exceeded the limit, Newsday’s analysis of lab reports found. That’s more than twice as many as the figure in the state’s database.
