As you recall this blog has reported on the proposal from City of Madison Engineering Division to add aluminum sulfate (alum) to the Arboretum’s Marion Dunn storm water pond on Monroe Street. Now, we have learned that the City has purchased all the “product and mechanics” necessary for the project. This according to Alder Zach Madden in Forward Lookout, a Dane County “news and opinion website with multiple authors.”
The Arboretum apparently remains publicly silent on the project.
This issue of Forward Lookout, called Permissible Pollution, also reports on mercury levels in a southside detention pond and construction site erosion that ended up in Lake Monona and that originated from the Ghidorzi construction site for the Wingra Clinic on Fish Hatchery Road.
As Tim Troester of City of Madison Engineering Division told the Committee on the Environment, the soil erosion from the Ghidorzi site was perfectly legal and within guidelines that permit 7.5 tons of soil erosion per acre, per site, per year.
Alder Madden poses the question: “In a city full of environmentalists, why are we failing at such basic things?”
