The city of Chicago will once again test for lead in some city tap water.
A spokesman for the Chicago Department of Public Health says his department and the Department of Water Management will test for the brain-damaging chemical in homes where children reported elevated lead levels in their blood.
Spokesman Matt Smith says the two city agencies had a similar program in 2011, which ruled out water as a source of lead in the children.
“Due to heightened awareness, and to validate that lead-based paint is the most likely source of elevated lead levels in children, the two departments will be resuming this program as a proactive measure to protect the health and safety of Chicago's children,” Smith said in an emailed statement
In February a group of residents sued the city over alleged lead problems in their water.
At the time, a spokesman for the Chicago Water Department said the city’s water is safe, “and exceeds federal, state and industry standards.”
A timeline for the resumed testing has not yet been set.
