In the news: A “stirring” solution to algae problems?

Jordan Lake in North Carolina suffers from a condition similar to Lake Erie – algal blooms that threaten wildlife and water quality. Due to nutrient runoff, the blooms continue to grow and pose a significant problem for the community that relies on it for water. 

While the EPA rules regarding processes and procedures to reduce runoff and mitigate the problem await implementation, there is a proposal for a potentially less expensive and more immediate way to reduce the algal blooms in the lake. 

"The N.C. General Assembly authorized a $1.44 million plan to put 36 floating water circulators into the lake. It’s a hefty price tag, but is actually one of the drivers for the experiment. If it works, the savings could be huge as costs for implementing the EPA rules are estimated at $1 to $2 billion.

Representatives from Medora Corporation, the company that will supply the mixers, say that the mixing process may confuse the algae, making them think they’re at different depths in the water. It could make them more vulnerable to viruses. The reps also say the mixers will work, claiming a 90 to 95 percent success rate in other lakes."
