TOLEDO, Ohio (AP) -- Algae that turned Lake Erie green and produced toxins that fouled the tap water for 400,000 people in the Toledo area are becoming a big headache for those who keep drinking water safe even far beyond the Great Lakes.
But with no federal standards on safe levels for drinking algae-tainted water and no guidelines for treating or testing it either, water quality engineers sometimes look for solutions the same way school kids do their homework.
'We are Googling for answers,' said Kelly Frey, who oversees a municipal system in Ohio that draws drinking water from the lake. 'We go home and spend our nights on the Internet trying to find how other places manage it.'
The contamination left about 400,000 people in parts of northwestern Ohio and southeastern Michigan without clean tap water for two days in August.
