Testing results must be reported to local public health agencies

Illinois provides IDPH with the weekly alert report of individual results that are above action level exceedances.

Schools and childcare facilities are required to test for lead*

Illinois schools (kindergarten through 5th grade) and childcare facilities are required to test for lead in drinking water.

Action level is at or below 12 ppb*^

Illinois does not have a more protective action level for lead in drinking water than the federal action level of 15 ppb.

Action level is at or below 5 ppb for schools and childcare facilities*^

In Illinois, parents and guardians must be notified of test results from schools that are 5 ppb or higher.
