Lake Erie algal bloom cleanup falling short of 40 percent phosphorus reduction goal

CLEVELAND, Ohio – Approaching the end of another summer marked by a substantial algal bloom in Lake Erie’s western basin, environmental and conservation groups released separate reports Tuesday that came to the same conclusion:

Ohio, Michigan and Ontario are falling far short in their efforts to reduce and eliminate the seasonal menace.

“The longer we wait to start putting algae-causing, pollution-reduction measures into practice, the worse the problems will become,” said Kristy Meyer, vice president of policy for the Ohio Environmental Council.

Meyer was responding to a new report released Tuesday, “Rescuing Lake Erie: An Assessment of Progress,” that examines how Ohio, Michigan and Ontario are responding to the goals of the Great Lakes Water Quality Agreement they signed two years ago.

The agreement committed the states and Canadian province to reduce phosphorus discharges by 40 percent between 2015 and 2025. In 2008, Ohio released 1,400 metric tons of phosphorus into Lake Erie. A 40 percent reduction would be about 860 metric tons of phosphorus, or roughly the same amount as released in 2010. Gov. John Kasich and the other group leaders are scheduled to meet next week at the 2017 Leadership Summit in Detroit.

Miles of Algae Covering Lake Erie

By JUGAL K. PATEL and YULIYA PARSHINA-KOTTAS OCT. 3, 2017

A potentially harmful algae bloom covered more than 700 square miles in the western basin of Lake Erie last week, turning the lake bright green and alarming residents and local officials.

Scientists say that algae blooms have been a growing problem for Lake Erie since the 2000s, mostly because of the extensive use of fertilizer on the region’s farmland.

The algae blooms contain cyanobacteria, which, under certain conditions, can produce toxins that contaminate drinking water and cause harm to the local ecosystem.

During last week’s bloom, the amount of toxins in the algae remained low at the intake points where towns draw water from the lake, according to officials.

Mayor Hicks-Hudson now wants Lake Erie declared impaired

Green water in lake, Maumee River has prompted health advisories

Toledo Mayor Paula Hicks-Hudson reversed course Tuesday and announced she would support the effort to get Lake Erie’s western basin declared impaired because of excessive algae.

The mayor made the announcement in Middlegrounds Metropark on the banks of the Maumee River, which was a blend of dark and near-florescent green.

The Toledo Lucas County Health Department issued a recreational public health advisory because of an algal bloom on the river in downtown Toledo. Two test results Saturday showed 1.8 and 11.8 parts per billion of microcystin in raw river water, both below the 20 ppb threshold the World Health Organization uses for avoiding all contact. City tap water, which is pulled from Lake Erie, was still safe to drink, officials said.

The bloom extended from the Anthony Wayne Bridge to Cullen Park, and advisory signs were posted at various access points.

Algal bloom on Lake Erie thrives in September heat wave

TOLEDO, OH (WTOL) 

While the algae bloom on Lake Erie continues to thrive in this warm weather, the scene along the Maumee River in downtown is looking worse.

Dr. Timothy Davis, associate professor of Biology with Bowling Green State University, has studied algae blooms all across the Midwest and even in Australia.

He said exactly like the bloom on Lake Erie, the bloom on the river is caused by the same factors: Excessive Nutrients, warm temperatures, and still water.

And with the current late September heat wave, as the river temperature has risen 23 – 25 degrees Fahrenheit and a dry spell that has completely slowed the Maumee flow down, it was a perfect storm for this bloom to grow.
When asked if the current dredging of the river could also be a factor, Davis said while it could have stirred up additional nutrients from the riverbed, there is no data to connect the dredging with the algae growth.

He said the bloom should be flushed out with a significant rain event.  And that once in the Lake, this river algae will not make the current Lake algae bloom any worse.

“The bloom in the western part of Lake Erie is so large and so massive, that even though we’ve seen the bloom in the Maumee, and that is somewhat rare or rarer that what we see out in the lake, it’s likely not going to impact,” Davis said.

And with microcystin levels above the recreational threshold, there won’t be many people swimming in the Maumee. But plenty of geese and other water fowl will be around the river.
Davis said prolonged exposure to the toxic algae could be dangerous to these animals, especially if they’re swimming in the more dense areas of algae scum.

But Davis said the fish population should be fine, as they swim through or under the algae. He also said eating fish caught in the river shouldn’t pose a threat to people.

The biggest threat to fish in the river is if the large algae bloom deoxygenated the water, but even then fish usually detect the low oxygen and move along.

City watches for dangerous Lake Erie algae blooms

For a city on Lake Erie, it’s the season for monitoring toxic algae blooms — and drinking water.

Harmful algal blooms continue to plague Lake Erie, threaten drinking water, fish, pets

The algae-clogged waters of Lake Erie's western basin at Maumee Bay State Park east of Toledo produced the growth of cyanobacteria and a toxin called microcystin that can be dangerous for people, birds, fish and pets.

An algal bloom contaminated with toxic bacteria shocked Toledo in August 2014, poisoning the city’s Lake Erie drinking water and forcing the city of 400,000 people to drink bottled water for three days.

Three years later, scientists are taking action to stay a step ahead of the harmful blooms, monitoring the algae and bacteria from outer space, from land, and in the water, with a new arsenal of high-tech tools and research projects.

What does disturbing new Lake Erie report mean for you? 01:0701:07

The EPA has released a scathing new report that finds Lake Erie is in “poor shape” when it comes to the other Great Lakes.

The report, released Wednesday, blames pollution, poor habitats, and algal blooms.

So what does that mean for people living in Northeast Ohio?

Channel 3 News inquired about the safety of drinking water, beaches and fish consumption.

According to the EPA, drinking water quality remains “good” and “unchanging” so long as it continues to be treated.
