GCSD Water Test Results

In accordance with New York State law, the Guilderland Central School District regularly conducts testing of all water outlets used for drinking and cooking to ensure the health and safety of the school community. The district recently initiated testing for the 2026-28 compliance period, which requires each outlet to test below the five parts per billion (ppb) lead threshold. Water outlets that exceed five ppb must be labeled with “do not drink” signage, remediated and re-tested to confirm they are no longer above the action level. At all times, the district takes steps to ensure that all students and staff have an adequate supply of clean water for drinking and cooking.

Lead testing was conducted in Oct. 2026 at 34 outlets across the Guilderland Central School District. Only five outlets, all located in Guilderland High School, tested over the five parts per billion (ppb) lead threshold. Hand Washing Only signs are placed at all five outlets. 

Following are testing results by building.
