TOLEDO, Ohio (AP) - The mayor of Ohio's fourth-largest city says water will be flowing into the Toledo area from all corners of the state to help the 400,000 people who are being warned not to drink the city's water.
Toledo's mayor says water is coming from Akron, Cincinnati and even a prison near Columbus.
City officials issued the warning Saturday after tests revealed the presence of a toxin possibly from cyanobacteria on Lake Erie.
Gov. John Kasich has declared a state of emergency in northwest Ohio that is allowing state agencies and the Ohio National Guard to begin delivering water.
Toledo Mayor D. Michael Collins says more tests are being run to determine if the water is safe. He hopes to have those results later Saturday.
Some Michigan communities are affected by water problems just across the state border in Toledo, Ohio.
The Monroe County health department says residents of Luna Pier, Bedford and Erie townships and a portion of LaSalle Township should follow restrictions announced by Toledo.
The restrictions have caused a run on bottled water at stores in the region. The Monroe News posted a photo on its website of empty shelves at a Meijer store in Frenchtown Township, Michigan.
An environmental group, Alliance for the Great Lakes, says the water crisis should be a "loud wake-up call" to stop the flow of cyanobacteria-causing nutrients into Lake Erie.
Clarification: An earlier version of this story referred to "algae blooms" in Lake Erie. These are really bacterial blooms (cyanobacteria) that look like algae. The copy has been clarified above.
