Wisconsin Brewing Co. uses unique technology to destroy blue-green algae in “Lake Sadie-Mae”

VERONA (WKOW) — As part of a $50,000 Urban Water Quality Grant from Dane County to the City of Verona, an innovative treatment was applied Wednesday to “Lake Sadie-Mae”, a pond adjacent to Wisconsin Brewing Company.

Although used commonly throughout the U.S., and the world, use of this technology is not common in Wisconsin. Using a specialized boat, the treatment sprays the surface of the pond with Aluminum hlorohydrate (ACH) to reduce phosphorus, which is the leading factor in the creation of hazardous blue-green algae.

The treatment was conducted by Harvey H. Harper, III, Ph.D., P.E. – President of Environmental Research & Design (ERD), Orlando, Florida.

“This is a process that is used heavily in Florida and a few other states are also using it,” Harper said. “It’s been around since the mid-70’s, but I understand it’s not been used very much in Wisconsin. We’re up here trying to demonstrate how effective it can be.”

The treatment should result in crystal-clear water by Thursday morning.
