LimnoTech’s environmental work on Lake Erie was recently featured in a multi-part series published in the Chicago Tribune on November 14, 2019. The series examines major issues affecting Lake Erie including harmful algal blooms, dead zones, and impacts of lake water quality on drinking water. LimnoTech staff are providing much-needed expertise to a range of organizations in the region including the City of Toledo, City of Cleveland, Great Lakes Observing System, Cleveland Water Alliance, Bowling Green State University, Ohio State University, Heidelberg University, Lake Erie Energy Development Corporation, US Environmental Protection Agency, US Army Corps of Engineers, Ohio Department of Natural Resources, and the National Oceanic and Atmospheric Administration.

The services LimnoTech is providing include real-time monitoring design and maintenance, data management and communication, data science and analytics, web tool development, fine-scale hydrodynamic and ecosystem modeling of hypoxia, harmful algal bloom monitoring and research, and nutrient fate/transport assessment and management. LimnoTech environmental engineer Ed Verhamme, our leading expert in environmental observing and sensor systems, is featured in the Tribune articles. Ed was interviewed by the Tribune while performing routine maintenance on environmental data sensors deployed at the City of Toledo water intake crib this past September. In the articles, Ed discusses our direct support for the City of Cleveland Water Department to identify the presence of a nearshore hypoxic zone.

The Chicago Tribune Connected Coastline series is supported by a grant from the Pulitzer Center to Tony Briscoe, an environmental reporter with the Tribune. Briscoe will be highlighting issues in each of the Great Lakes over the coming year.

The shallowest Great Lake provides drinking water for more people than any other. Algae blooms are making it toxic — and it’s getting worse.

In the Great Lakes’ most productive fishing grounds, algae-fueled dead zones are eroding livelihoods

Cleveland residents are used to their water being brown, even if they don’t know why. The answer lies at the bottom of Lake Erie.
