Wet Pond Modeling for Contaminant Retention and Maintenance
Many of the more than 30,000 ponds in Minnesota are connected to stormwater pipes and act as a part of the stormwater treatment system by storing runoff and settling solids along with associated pollutants to the bottom of the pond. Many of these ponds are stratified at one-foot of depth, and have high organic matter levels, often creating a bottom region of low dissolved oxygen water resulting in re-release of phosphorus trapped in the bottom sediments back into the water column. Through modeling efforts and field measurements, this research will further investigate pond maintenance approaches to mitigate phosphorus pollution from ponds. Results from this study can be used to maintain and apply design retrofits to existing and new ponds to improve pond performance and benefits for use along roadways throughout Minnesota and the United States.
