Two Democratic lawmakers want the state Department of Health Services to investigate drinking water as a possible source when children are lead poisoned. The proposal also greatly lowers the blood lead levels that would trigger an investigation.
Nearly 4,000 children in Wisconsin were diagnosed with elevated levels of lead in their blood in 2014, though the number has fallen over the years thanks in part to bans on lead in paint and gasoline. Unlike in Flint, Michigan, however, no one knows how much lead in the drinking water contributes to elevated blood lead levels in Wisconsin. There are no requirements to test the drinking water when a child is lead poisoned.
