Freshwater Science Teaser: A Toxin Forecast for Lake Erie’s Harmful Algal Blooms

OHSU-CAST-1696
Freshwater Science Teaser: A Toxin Forecast for Lake Erie’s Harmful Algal Blooms

Scientists are currently able to accurately forecast the size and approximate location of Lake Erie’s summer harmful algal blooms, but they still have questions about what controls when blooms become toxic, and how to predict which algal toxins the bloom is likely to produce.

Dr. Justin Chaffin at Ohio State’s Stone Lab is studying the environmental factors that cause Lake Erie algal blooms to become toxic or remain non-toxic, to provide more guidance to water utilities on when they should plan to treat drinking water for algal toxins.

Freshwater Science Teaser: Lake Erie Algae in the Depth of Winter

Although harmful algal blooms happen in the summer, the algae themselves are year-round residents of the water bodies they inhabit – but very little is known about other times in the annual cycle of blooms. For Lake Erie, ice cover and extreme weather conditions in winter and spring prevent regular monitoring and safe sampling.

By partnering with the U.S. and Canadian Coast Guards, Dr. Mike McKay at the University of Windsor can take advantage of those ships’ ice-breaking capabilities to sample offshore waters in winter and early spring, before state and federal agencies start their monitoring efforts.

Freshwater Science Teaser: Using Bacteria to Remove Microcystin from Drinking Water

OHSU-CAST-1695
Freshwater Science Teaser: Using Bacteria to Remove Microcystin from Drinking Water

Many Ohio communities draw their drinking water from Lake Erie, so making sure that any harmful algal bloom toxins are removed before the water reaches consumers is essential to maintaining public health.

While water treatment plants currently use activated carbon, ozonation, and other methods to treat for algal toxins, Dr. Jason Huntley at The University of Toledo, with funding from the Harmful Algal Bloom Research Initiative is developing new cost-effective, efficient, and safe methods to remove algal toxins from drinking water, using bacteria that naturally break down microcystin toxin into non-toxic component parts. The team was issued a patent on this technology in May 2021.

Freshwater Science: Stopping Algal Bloom Toxins at the Kitchen Tap

OHSU-CAST-1682
Freshwater Science: Stopping Algal Bloom Toxins at the Kitchen Tap

Harmful algal bloom toxins are a common concern for people living along the Lake Erie shoreline, where drinking water is often drawn from the lake.

In addition to removing these toxins during water treatment, Ohioans may have another tool at their disposal: Dr. Glenn Lipscomb’s research, funded by the Harmful Algal Bloom Research Initiative, has shown that reverse osmosis membranes, an essential component of home water purification systems, can remove algal toxins from drinking water. The mechanism by which toxins are removed will be discussed along with tests for commercially available units.

Freshwater Science Trailer: Removing Algal Toxins from Drinking Water with Activated Carbon

OHSU-CAST-1679
Freshwater Science Trailer: Removing Algal Toxins from Drinking Water with Activated Carbon

During harmful algal bloom season, algal toxins can be common in drinking water drawn from Lake Erie. Water treatment plants are well set up to manage this issue for their customers, and often use powdered activated carbon to remove toxins, but they lack data on proper dosage depending on toxin types, toxin concentration and water properties.

Dr. John Lenhart, with funding from Ohio Sea Grant and the Harmful Algal Bloom Research Initiative, is developing these guidelines and sharing them with water treatment plant operators along the Lake Erie shoreline to help reduce the cost of safe drinking water.

A half-hour webinar on the same topic is also available.

Harmful Algal Bloom Research Initiative

OHSU-CAST-1617
Harmful Algal Bloom Research Initiative

Funded by the Ohio Department of Higher Education, with matching funds by participating universities, the Harmful Algal Bloom Research Initiative (HABRI) was created in the aftermath of the 2014 Toledo water crisis. Led by representatives from The Ohio State University and The University of Toledo, and managed by Ohio Sea Grant, the initiative provides near-term solutions for the full suite of issues surrounding harmful algal blooms.
