Since 2016, New York state law has required school districts to conduct lead testing of all water outlets used for drinking and cooking every five years. The law was amended in January 2023, reducing the time frame for testing to every three years, unless the state commissioner of health requests individual districts to test sooner. Effective Jan. 1, 2023, the testing deadline for the 2023-2025 compliance period is Dec. 31, 2025.
Additionally, the state’s revised action level of lead in drinking water is 5 parts per billion (ppb), reduced from 15 ppb. School buildings deemed “lead-free” are no longer exempt from testing requirements. Bathroom sinks are no longer required to be tested, where controls (e.g. education and signage) exist to prevent consumption.
In accordance with the law, the Guilderland Central School District chose Intertek-PSI to collect samples throughout all district buildings during the current testing cycle. According to New York state, if the lead level from a tested water outlet exceeds the action level of 5 parts per billion (ppb), the district is required to take steps to prevent the use of the outlet for drinking or cooking purposes until it is remediated and follow-up testing confirms it is no longer above the action level.
School districts are required to report the results of all water testing to staff, students’ families, the state Department of Health, the state Education Department and the local health department, and to post the results — along with remediation plans, if required — on the official district website. At all times, the district will ensure that all students and staff have an adequate supply of water for drinking and cooking.
Below are the water testing results from June 2024 by building. As remediation is complete, this webpage will be updated.
