Toledo curtails testing as microcystin levels rise
Though the amount of microcystin present in raw Lake Erie water near Toledo’s water-system intake Wednesday was double the amount detected two days earlier, city officials announced they planned to scale back testing for the toxin. Tests showed the raw water Wednesday afternoon contained 1.0 parts per billion of microcystin. Tests showed 0.5 ppb Monday and 0.4 ppb Tuesday. Despite the rising levels, city officials have said they plan to discontinue daily testing for the toxin that contaminated the city’s drinking water for nearly three days last summer. Instead, the city will draw samples daily but test the water only once a week, city spokesman Stacy Weber said.
