Update Monday, August 4th, 9:40am: Toledo Mayor D. Michael Collins says the water ban is lifted in northwest Ohio and drinking water for 400,000 residents is safe. We'll have more details as they come in.
Sunday, August 3, 2014: More than 400,000 people in Toledo and surrounding areas are without drinking water for a second day, due to a huge cyanobacteria bloom in Lake Erie, where the area gets its water supply. The cyanobacteria, sometimes referred to as blue-green algae, create a dangerous toxin called microcystin, and exposure to the toxin can cause serious health issues.
On Sunday afternoon, a boat hastily chartered by the National Wildlife Federation cruises over to see the massive cyanobacteria bloom floating near the city of Toledo. It's hot, and it's a pretty day, but the water looks oddly bright green.
That's the cyanobacteria bloom. The blooms have been appearing for a couple of decades, but they're getting worse.
Toledo Councilman Larry Sykes says he and other officials have been worried about this for a long time.
