Water Testing Results


To protect Illinois children from possible exposure to lead in drinking water, Governor Bruce Rauner and the General Assembly passed Public Act 99-0922 requiring schools and daycares to sample for lead contamination in water. The complete law and requirements are accessible on the Illinois Department of Public Health (IDPH) website at


While the current federal EPA acceptable threshold is 15 parts per billion (ppb), the State of Illinois has set a more stringent threshold of 5 parts per billion (ppb). District 103 has set an even higher expectation of "zero trace" in any of the tests taken. In addition, Illinois only requires the testing of drinking water in buildings up to 5th grade, including testing of any Early Childhood (EC) – Kindergarten classrooms that may have a sink. Again, District 103 has set a higher standard of all buildings being tested.


In April 2016, District 103 took a proactive approach to test for lead in the drinking water by testing 45 drinking fountains and 5 sinks used for cooking or medical necessity. Those test results and the remediation completed are available on the District website at However, based on the new State of Illinois requirements, District 103 needs to test the water in classrooms for EC – Kindergarten. Once again, District 103 has taken a proactive approach by testing all classrooms at Laura B. Sprague School on February 23, 2017. Along with testing the water in the classrooms, the District has also tested the water in the following locations: Room 23 (social workers' room) at Sprague; drinking fountains replaced at Sprague and Half Day under the April 2016 remediation; Room 120 (teachers' lounge) at Daniel Wright; and Room 122 (guided program's office) at Daniel Wright.


District 103 is continuing its proactive approach in the testing of water, even though locations like Room 23 at Sprague and Rooms 120 & 122 at Daniel Wright are not technically required under the new law. All test results have indicated "zero trace," with the exception of Room 23 at Sprague and Room 122 at Daniel Wright. The new law requires that we collect two samples, with a thirty-second flush between samples. Sample #1 in Room 23 at Sprague has indicated 33.83 (ppb), while sample #2 has shown zero trace. Sample #1 in Room 122 at Daniel Wright has indicated 18.26 (ppb), while sample #2 has come back with zero trace. The samples at both locations have been re-tested to confirm these findings. When the District received the test results by phone late on Friday, March 3, 2017, the water supplies to both locations were immediately shut off.


Next steps require District 103 to notify our community and the IDPH. Once the IDPH receives the District's results, remediation steps will be provided. Until remediation is completed, the water supply to Room 23 at Sprague and Room 122 at Daniel Wright will remain off.
