cyanobacteria

More than one billion dollars has been spent in the U.S. since 2010 dealing with algae blooms that potentially harbor toxic cyanobacteria. A report by the Environmental Working Group’s analysis found the majority of that money was spent in Ohio. That state has spent more than $815 million as it struggles to control algae blooms in Lake Erie and some other inland lakes. Lake Erie is a hot spot for cyanobacteria.

The group’s analysis found Michigan only spent thousands of dollars around Lake St. Clair and that came from communities and homeowners.

Western Lake Erie is expected to see only a moderate bloom of cyanobacteria this summer. The cyanobacteria can produce toxins that are harmful for people and pets.

Scientists from the National Oceanic and Atmospheric Administration and regional institutions predict the 2020 summer cyanobacterial bloom will be among the smallest since 2011.

Scientists have concluded it's going to be more difficult than they initially thought to reduce phosphorus loads into Lake Erie by 40%.

That's the target set by Great Lakes states.

Phosphorus is a crop fertilizer that also encourages cyanobacterial blooms. 

Rebecca Muenich worked on a study to evaluate ways to control the blooms. 

Meunich is a former researcher at the University of Michigan's Graham Sustainability Institute, and now an assistant professor at Arizona State University.

Researchers say the harmful cyanobacteria bloom on Lake Erie this past summer was the fifth largest since they began ranking them going back to 2002.

The National Oceanic and Atmospheric Administration says the bloom covered about 700 square miles by the end of August.

Dozens of water activists attended a conference in Flint Wednesday.

The conference examined the ongoing effects of lead, PFAS and other contaminants turning up in public drinking water supplies.

The cyanobacterial bloom on Lake Erie has grown 20 miles in the past week. It now covers 620 square miles of Lake Erie, taking up about 6 percent of the entire lake and covering more area than Detroit and its suburbs. 

Five years after half a million Toledo-area residents were told not to drink or touch their tap water for two days, the same thick green sludge responsible for the 2014 water crisis has now spread across 600 square miles of western Lake Erie.

Researchers predict a large cyanobacterial bloom in Lake Erie this year.

But it will probably not be as bad as 2011 and 2015, when the blooms covered a large area of western Lake Erie.

The state of Ohio has stepped into a court battle over whether Lake Erie has legal rights. 

In February, Toledo voters approved the charter amendment by a large margin. The amendment claims city residents have the legal right to protect Lake Erie.

Toledo lies on the shore of the western part of the lake, which is plagued with cyanobacterial blooms, largely caused by fertilizer runoff from farms. In 2014, the city of Toledo briefly shut down its water system, after its Lake Erie water intake was surrounded by a bloom of toxic cyanobacterial.

The U.S. Environmental Protection Agency says it wants to keep Americans safe while swimming. So it's announced new recommendations for two cyanotoxins in recreational bodies of water. 

Cyanotoxins are produced by bacteria blooms that have become increasingly common in places like western Lake Erie. Exposure to them at unsafe amounts can cause upset stomachs and liver and kidney damage.

Experts say heavy rains this spring make it more likely western Lake Erie will see another significant bloom of toxic cyanobacteria later this year.

The bloom's size will ultimately depend on rainfall amounts from now through early summer.

Scientists with the National Oceanic and Atmospheric Administration have issued their first forecast of the year for the lake. They're projecting the bloom will be more severe than last year, which saw a relatively mild outbreak.

Toledo voters have approved a charter amendment giving Lake Erie legal rights by a large margin, 9,867 to 6,211. 

Turnout in the special election, which also included a referendum on whether to keep the city's jail downtown, was 8.9% of registered voters.

The charter amendment purports to allow any city resident to sue to protect the lake.  

A new study from the University of Michigan shows that blooms of harmful cyanobacteria in Lake Erie are so tough they can survive the winter.

Researchers with Ohio Sea Grant and the National Oceanic and Atmospheric Administration (NOAA) say cyanobacterial blooms in Lake Erie will likely be smaller than last year.

The forecast relies on satellite imaging and computer models to predict the toxic blooms every summer. 

Christopher Winslow, Director of the Ohio Sea Grant College Program, says this summer's prediction is about 6 on a scale of 10. 

We’re coming up on the time of year when people will be testing lakes for toxic blooms of cyanobacteria.

Jason Deglint wants to speed up that testing process. Right now, he says it can take at least a few days.

A new report from the Ohio Environmental Protection Agency says that despite billions spent in the Lake Erie watershed to improve water quality, there has been no clear trend of reducing phosphorus levels in the state’s watersheds.

Runoff of nutrients, mainly phosphorous, from agriculture have been blamed for a series of toxic cyanobacteria blooms in Lake Erie. Ohio has spent more than $3 billion to improve the Lake Erie watershed since 2011.

An advisory board with the International Joint Commission says the U.S. and Canada should do more to keep nutrient pollution out of Lake Erie.
