Madison, Wisconsin, the second-largest city in Wisconsin, did something incredible with their water supply. They replaced every single lead pipe in the city’s water system in response to the lead concentration in the water supply being one part per billion over the federal Environmental Protection Agency (EPA) limit for lead concentration in the water:
Long before Flint, Mich., faced a water-contamination crisis, this city dealt with one of its own. The local utility had sampled residents’ tap water in accordance with the federal government’s new Lead and Copper Rule and discovered unacceptable levels of lead.
But Madison’s response was like hitting a gnat with a sledgehammer. It was so aggressive that only one other major municipality in the United States has followed its approach so far. It’s also why some people now call Madison the anti-Flint, a place where water problems linked to the toxic substance simply couldn’t happen today.
Madison residents and businesses dug out and replaced their lead pipes — 8,000 of them. All because lead in their water had been measured at 16 parts per billion — one part per billion over the Environmental Protection Agency’s standard.
Although the federal government defines lead contamination of water as the lead concentration level in water being over 15 parts per billion, no level of lead in water is safe. Madison has proved yet again why it’s America’s most forward-thinking city.
