Minnesota Stormwater Seminar Series

Biofiltration Media ? Phosphate release or capture, plant growth, chloride impacts, and more!

Please join us online or in person on April 13, 2023 at 2p CDT for the next Minnesota Stormwater Seminar Series event - a monthly experience featuring national, state, and local experts on stormwater and green infrastructure. This seminar series is a partnership between the University of Minnesota's St. Anthony Falls Laboratory and Water Resources Center, and the Minnesota Pollution Control Agency, and made possible through the?Minnesota Stormwater Research and Technology Transfer Program in collaboration with the Minnesota Stormwater Research Council.

*Title:?*Biofiltration Media ? Phosphate release or capture, plant growth, chloride impacts, and more! [ [link removed] ]

*Keynote Speaker: Andy Erickson*, Research Manager - St. Anthony Falls Laboratory, University of Minnesota

*Abstract:*?Biofilters are rain gardens with underdrains that treat stormwater runoff from urban landscapes, especially where infiltration into shallow groundwater is infeasible or a concern. The biofilter media (e.g., sand, compost, peat, biochar), however, can release phosphate or limit plant growth, so stormwater professionals struggle to choose which media to use in biofilters. A four-year outdoor research study evaluated thirteen different mixes of eight different media components to determine benefits and consequences of using common and new innovative media components in biofiltration media. This presentation will share the final performance results including phosphate release or capture, plant growth, filtration rate, impacts from road salt addition on phosphate release, and simple tests and metrics that could be used to determine which components have potential to release phosphate. The final recommendations from this project are intended to guide stormwater practitioners towards better designed biofiltration practices that capture phosphorus and support healthy vegetation.

*Date and Time:?*Thursday, April 13, 2023, 2 - 3pm CDT
