CHICAGO -- The concern over lead in the drinking water at some Chicago Public Schools is the topic of a City Council committee hearing on Wednesday.
CPS officials say 327 schools have been tested for lead in the water. 113, more than one third, had at least one water device showing high levels of lead.
With students heading back to class on Tuesday, CPS officials say affected sources have been repaired and retested or taken out of service.
CPS says those water sources are now turned off as a temporary solution, and it's developing a plan to fix the problem. But, Alderwoman Susan Sadlowski Garza says putting paper bags over water fountains isn't enough, and instead the fountains need to be removed altogether.
Even small amounts of lead can cause students to have developmental problems.
200 schools still need to be tested.
