City watches for dangerous Lake Erie algae blooms
Update 9/12/2017: The City of Toledo has moved its water quality dashboard back to clear.
For a city on Lake Erie, it's the season for monitoring toxic algae blooms -- and drinking water.
Toledo Ohio know how dangerous the blooms can be. In 2014, toxins contaminated its water supply, forcing a "do not drink or boil” advisory for two days.
The city recently downgraded its water quality rating from "clear" to "watch." That came after the level of a very dangerous toxin called microcystin rose in Lake Erie .
However, Toledo stresses that microcystin is not in tap water --- just in the lake and near the water intake crib.
Now, the city is treating drinking water to remove the toxin. And it’s watching levels of microcystin, which is more toxic than cyanide and can make humans and pets sick.
It’s a byproduct of the algae blooms created by fertilizer runoff and other problems in western Lake Erie. During an algae bloom, the lake might look green, with floating layers of scum.
The latest harmful algae bloom bulletin for western Lake Erie shows the bloom continuing along the Michigan and Ohio coasts, but decreasing in toxicity. This year is predicted to be one of the largest blooms on record.
