TOLEDO, Ohio - Ohio Gov. John Kasich says all of the state's agencies are working to bring water and other supplies to areas around Toledo where some 400,000 are being told not to drink from the city's water system.
Kasich tells The Associated Press it's too early to say how long the water advisory will last and what triggered it.
Ohio officials are awaiting the results of more tests on the water that could determine how much longer residents in and around the state's fourth-largest city are without water.
Ohio's EPA director says the agency is trying to figure out what caused a sudden spike in the toxins.
Jason Wood, Director of Public Affairs for the city of Cleveland says "there are a couple of reasons that makes this less likely to occur here. One is the fact that it’s in the western basin of the lake. Cleveland and our intake sits in the central basin, the western basin is a little shallower so the water gets a little warmer. There is more agriculture in the region than there is here."
Toledo issued the warning early Saturday. It said tests at one treatment plant returned two sample readings for microsystin above the standard for consumption.
The city warned against boiling because it will only increase the toxin's concentration. The advisory covers city residents and those in Lucas County served by the city's water supply.
The city's advisory says Lake Erie may have been affected by a bloom of harmful algae that produces the toxin. Consuming the tainted water could result in vomiting, diarrhea and other problems.
Toledo is home to about 280,000 people. The city says more tests are being run.
