ILLINOIS (AP) — One of Illinois’ leading environmental groups want new requirements for schools to test their pipes for lead.

The Illinois Environmental Council is pushing for a law to require elementary schools in Illinois test for high levels of lead in drinking fountains, sinks and other water sources. Council boss Jennifer Walling says there’s no safe level of lead for young kids.

Illinois’ Association of School Administrators say the goal is worthy, but they worry about adding another cost to the state’s already cash-strapped schools.
