Marc Edwards of Virginia Tech University was one of the first the raise the alarm about staggeringly high levels of lead in Flint water.
For that, he was ignored by staff at the Michigan Department of Environmental Quality.
That was last summer. Now, Edwards is returning to Flint, bringing his expertise on water treatment and corrosion to the new Flint Water Interagency Coordinating Council.
"We need to replace these lead pipes. If we don't do it, they will literally be there 1000 years, and every time people forget about them they will come back and bite us. I mean, that's the history of lead pipes in this country and around the world," Edwards says.
Edwards tells is about his expectations in Flint in our conversation above.
