(NEWSER) – Think the Flint water crisis is bad? It's only "the tip of the iceberg," says Erin Brockovich. During an appearance on The Late Show on Thursday, the environmental activist explained lead-laced water has also been found in Sebring, Ohio; Louisiana; and possibly Wisconsin.
"I can tell you for certain this is a national crisis that we're not getting ready to face—this crisis is already here," she said, per WNEM. She explained America's use of chloramines during the water-treatment process is an issue: It's "very acidic … Our infrastructure is very old. And it's causing all the iron and the lead ... and the copper and everything in these pipes to leach out."
