Lead in our schools' water: Our report that preceded legislation

Our continuing series on suburban water quality contributed to real legislation.

A bill that requires testing of drinking water in all Illinois schools for lead contamination was approved unanimously Tuesday by the Illinois Senate. The bill is expected to be signed by Gov. Bruce Rauner, whose administration worked with schools, testing advocates and Illinois Attorney General Lisa Madigan's office to remedy concerns over costs and responsibility for testing.

The Daily Herald reported last month on the level of testing suburban school districts had applied to their water supplies. Some tests showed lead levels well above the federal safety threshold, in one case more than 212 times that threshold. More than 75 percent of the schools tested in compliance, while some schools were not tested at all.
