Flint, Michigan is in the news for lead in the water. But there’s lead – and higher levels – all over this country. We’ll dig in.

The lead in the water in Flint, Michigan is appalling, frightening. The whole country’s finally focused on it. But the fact is, there are serious lead threats, problems, all over this country. And no small number – maybe in your community – are worse than Flint’s. Lead can cut IQ, retard development, breed behavioral problems, even crime. And very often, we just let it flow. This hour On Point, the map of America by lead problems, way beyond Flint. And what to do about it.

From Tom’s Reading List

Michigan Radio: Flint looks to Lansing for lessons in lead service line replacement -- "Flint’s mayor, Karen Weaver, says she doesn’t want to waste any time getting rid of the city’s old lead service lines. It’s those lines – which bring water from the main to Flint houses – that have caused so much trouble in the city. Flint did not treat the water from the Flint River properly. That meant it ate away at those pipes and contaminated the water in many homes with lead."

New York Times: Unsafe Lead Levels in Tap Water Not Limited to Flint — "Unsafe levels of lead have turned up in tap water in city after city — in Durham and Greenville, N.C., in 2006; in Columbia, S.C., in 2005; and last July in Jackson, Miss., where officials waited six months to disclose the contamination — as well as in scores of other places in recent years."

The Atlantic: An American History of Lead Poisoning — "Over the past century, tens of millions of children have been poisoned by lead, mainly by its presence in old household paint. And many more will be, thanks to the hundreds of tons of lead paint that remains on the walls of houses, apartment buildings, and workplaces across the United States, decades after a federal ban. Many of the most vulnerable are children living in poor neighborhoods of color."
