At 6:45 a.m. on Aug. 2, Doug Haynam was awakened by a phone call from his son.

“I’m in Perrysburg getting water,” his son said. “Do you want some?”

That’s how Haynam, a Sylvania city councilman, learned the water supplied to him and 500,000 other people across northwest Ohio and southeast Michigan was contaminated and that he shouldn’t drink, touch or boil it.
