Study Finds Effective Treatments for Removing Contaminants from Stormwater Runoff

Posted: Aug 2, 2022

Researchers at South Dakota State University found that mixed media filtration using steel chips and steel slag can be used as an effective treatment tool to remove E.coli and phosphate from stormwater runoff. This filtration technology will improve stormwater management and protect natural water resources. Urban stormwater has been recognized as a major source of water contaminants, and conventional stormwater best management practices are generally not effective in removing microorganisms and nutrients. This research addresses the critical need to develop effective treatment technologies that can remove contaminants in stormwater runoff.
