CATAWBA ISLAND — If toxic algae continues to plague Lake Erie at high levels, some water treatment plants might not be able to guarantee they can provide drinking water, officials said.
Last summer, toxin levels in raw, untreated water were higher than Ottawa County Sanitary Engineer Kelly Frey had ever seen.
Ottawa County’s water treatment plant added extra chemicals and ran additional tests to make sure the toxin had been removed from the drinking water. The toxin, microcystin, is released when the harmful blue-green algae in the lake dies.
Although the algae is gone until next year, Frey is still concerned about what the plant will do to address the problem next summer.
