Nearly half a million people in northwestern Ohio have been given the OK to drink their tap water, after officials warned of an algal toxin in it Saturday and issued a ban on using it. The mayor of the city of Toledo said Monday morning that it was now safe to use, after the governor had declared a state of emergency earlier in the weekend and the Ohio National Guard had distributed tens of thousands of gallons of clean water. The algae bloom that tainted the water has been blamed on the sewage and fertilizer that had streamed into Lake Erie from plants and farms.
