Many thanks to Marty Cieslik from Upper Sugar River Watershed Association (USRWA) for joining us yesterday! He discussed the Aluminum Chlorohydrate (ACH) treatment to an 8.3 acre stormwater management pond in Verona. The pond was built in 2004 for the Verona Technology Park and has become an integral part of Wisconsin Brewing Company’s grounds. Consistent algae blooms are a concern for this dog-friendly local brewery, limiting the pond’s use due to poor water quality and potential liability issues associated with Cyanobacteria toxins. Emphasis on meeting TMDL’s in the Madison Lakes region lead to this project, demonstrating the use of aluminum compounds to enhance phosphorus reduction goals. Thanks for sharing your knowledge with our staff!
