VLAWMO is pleased to partner with Barr Engineering for an innovative research project during the Summer of 2021.
This research project will take place at a pond located just north of Ash St. in Lino Lakes. The aim is to find economical ways to keep the phosphorus in bottom sediments from releasing into pond water. If successful, what we learn may be applied to other storm ponds and water bodies across Minnesota and beyond. Spent lime is a focus in this study because of its abundance as byproduct in the drinking water filtration process.
A similar study will take place this summer in Saint Paul, in Wakefield pond, which contributes water to Wakefield Lake. Spent lime application in both ponds has been approved by the Minnesota Pollution Control Agency and is determined to be safe for fish and other wildlife.
Research results will be posted here when they're available in late 2021.
