To protect public health, the Public Health Law and New York State Health Department (NYS DOH) regulations require that all public school districts and BOCES test lead levels in water from every outlet that is being used, or could potentially be used, for drinking or cooking. If lead is found at any water outlet at levels above 15.0 parts per billion (ppb), which is equal to 15.0 micrograms per deciliter (mcg/dl), the NYSDOH requires that the district take action to reduce the level of lead.
