TOLEDO, Ohio (AP) — Several water-treatment plant operators are raising concerns about harmful blue-green algae in western Lake Erie and the lack of protocols for keeping the algae's toxin out of the public water supply.
The Blade in Toledo (http://bit.ly/1aOOIF2 ) reports those issues were discussed at a forum Thursday in northwest Ohio.
Ottawa County Sanitary Engineer Kelly Frey calls it "unbelievable" that there aren't state or federal standards for detecting the algae at municipal water-treatment plants.
Several plants along Lake Erie test voluntarily and use various methods to try to neutralize the toxin. Barry LaRoy, the water director in Monroe, Mich., says facilities are doing the best they can without official guidance.
Last fall, one Toledo-area township temporarily ordered residents to stop using the drinking water when tests showed increased levels of the toxin.
