Water Quality Testing 


At Chicago Public Schools (CPS), our top priority is ensuring the health and safety of our students and staff, and we take a proactive approach to maintaining safe drinking water in our schools. Lead can be found in pipes, faucets, and interior plumbing fixtures and materials and we believe that routine water testing is an important and necessary action to ensure the safety of our drinking water.

As part of our commitment to ensuring the health and safety of our students and staff, CPS began testing water in our schools and facilities. While all schools will be tested, the testing schedule was developed based on criteria that includes the age of the school, age of the students (with priority given to schools with pre-K programs), presence of a kitchen (where meals are prepared), and presence of pipes that could need repairs or replacement.

In 2016, CPS began the first round of our district-wide water testing program out of an abundance of caution to ensure water in our facilities met all federal, state, and local regulations.

CPS collaborated with the Chicago Department of Water Management (CDWM) and the Illinois Department of Public Health (IDPH) to establish testing procedures and protocols that help ensure the quality of potable water in schools.

In addition to state requirements, CPS also took the additional step to test water quality on an ongoing basis, and began a second round of comprehensive testing program starting in Spring 2019 through end of school year 2022.

Results of lead tests will be routinely posted on this page.
