Water Testing Results

  • New legislation in New York State was passed earlier this year requiring all school districts to test potable water systems for lead and to take responsive actions. The new regulations require lead not to exceed 15 parts per billion (ppb) in the tested water, which is lower than the United States Environmental Protection Agency’s (EPA) acceptable lead level of 20 ppb.

    In accordance with New York State legislation, testing was completed at all schools within Williamson Central School District as follows: Elementary School was tested on September 22, 2016; Middle School was tested on November 28, 2016; and High School was tested on November 28, 2016. The results of the tests are as follows:  

    • Williamson Elementary School – Out of 141 outlets tested, 15 exceeded NYS ppb requirements.
    • Williamson Middle School – Out of 60 outlets tested, 16 exceeded NYS ppb requirements.
    • Williamson High School – Out of 74 outlets tested, 16 exceeded NYS ppb requirements. 

    Of the 249 outlets tested within the district, a total of 47 outlets exceeded NYS ppb requirements with 33 of those outlets being classroom outlets, 7 being kitchen outlets, 5 being bathroom outlets and 2 being water fountain outlets.

    Based on these results, Williamson Central School District has taken the following immediate actions:

    • Signs stating “Handwashing Only” have been posted at the affected sinks.
    • Water has been turned off at the affected drinking fountain and kitchen outlets.

    All water outlets exceeding the ppb requirement of 15 ppb will either have fixtures replaced and/or have piping repairs completed as remediation actions needed to address these results.

    We will be conducting a second round of testing to assure that the replaced outlets meet New York State requirements. As we receive the results we will follow the same process and we will continue to keep you updated.

    The health and safety of Williamson Central School District’s students, faculty and staff is a top priority and we will work to fulfill all aspects of the New York State Department of Health’s newest water testing regulation.
