Problem is the pipes, not the river per se. When they switched water, they didn't add an anti corrosive agent: http://www.freep.com/story/news/local/michigan/2

  >> Problem is the pipes, not the river per se. When they switched water, they didn't add an anti corrosive agent Which means there is now corrosion in a lot of old lead pipes, which means the lead will continue to get into the water for a while. IIRC at least a few months after they switched back and possibly longer.

  And the water, it sounds like it's substantially more corrosive than their previous water supply.
