For more than a decade, algal blooms have turned many Ohio waterways into thick, green mush, choking fish and turning the water toxic to humans. Runoff from farm fields is the biggest culprit.

Governor John Kasich signed an executive order earlier this month to help regulate the runoff, but a panel appointed by the governor himself has sidelined the order, calling instead for further study.

Gov. John Kasich found himself in some hot water after saying in a recent speech that he doesn’t believe Lake Erie is impaired, contradicting a declaration from his own Environmental Protection Agency in March. Now Kasich is clarifying those comments.

Billions of dollars have been allocated to restoring the Great Lakes – money spent cleaning up pollution, preventing invasive species and educating the public.

A new regional initiative will analyze how effective some of those efforts – and dollars – have been so far.

Ethan Wells has lived along the Ohio River for almost all of his 32 years. One day last August near his home in Sistersville, an hour south of Wheeling, West Virginia, he noticed blue-green algae growing along the riverbank. And each time he looked, there was more of it.

Congresswomen from Ohio and Michigan are urging federal officials to designate western Lake Erie as an impaired waterway because of the harmful algae that is hurting the lake.

Commercially available water pitchers with filters can rid drinking water of toxins produced by algae blooms. The research done at Ohio State University’s Stone Lab on Lake Erie shows some are better at the task than others.

Late Summer Brings Renewed Worries About Algae

The tail end of summer can be a big problem for many of Ohio’s lakes. The combination of farmland runoff and high temperatures is ideal for algae growth, which has plagued Ohio's lakes in recent years.

The National Oceanic and Atmospheric Administration says this year’s algal bloom in western Lake Erie should be less severe than last year.

Runoff and the Health of Ohio’s Water

The Environmental Protection Agency is warning that toxic sediment is threatening Cleveland's water supply. The poisonous sediment, dredged from the Cuyahoga River, was dumped into Lake Erie before the regulations put in place by the 1972 Clean Water Act. This has once again raised concerns over the impact of agriculture runoffs from fertilizers and manure.

Some cities and towns are pushing back against new water testing rules proposed by the Ohio EPA. The state environmental agency wants local water supplies tested weekly for algae. Some water authorities have complained that the testing is too costly and too frequent.
