Item Pollutant Removal and Maintenance Assessment of Underground Sand Filters(2021) Shoemaker, Todd; Stone, Ali; Zhang, Lu; Fesenmaier, Mark; Stantec; Water Resources CenterThe purpose of this study is to evaluate the stormwater management effectiveness of installed underground sand filters in the Twin Cities Metro Area. The Minnesota Stormwater Manual includes guidance for the design and pollutant removal efficiency of surface and one type of underground sand filters. The most popular variety of underground sand filter, however, does not offer clear access to the sand media layer and is not included in the Minnesota Stormwater Manual. Maintenance is extremely limited by this design, which calls into question whether they can actually achieve the same removal efficiency as their aboveground couterparts, and whether those efficiencies degrade over time. There is limited data regarding performance of in-situ underground sand filters to assist in this evaluation. Some underground systems in the Metro have been installed for a decade, but their long-term performance has not been evaluated. Award of this grant would provide funding to investigate underground filtration performance. Study results will inform maintenance needs, judge longevity of these systems, provide design recommendations to design engineers, or if found to be an inadequate stormwater BMP, offer regulatory recommendations to watershed managers.

Multiple sources and approaches were used to identify stormwater research needs for Minnesota, including a review of relevant stormwater-related documents, and state-wide survey of stormwater managers, focus groups, and policy actor interviews. The Stormwater Research Roadmap for Minnesota identifies eight major areas that need additional research to improve stormwater management for communities, professionals, and agencies. Specific examples are included for each. Research in these areas can lead to more innovative management techniques and increased effectiveness and efficiency to prevent, minimize, and mitigate the effects of runoff from the built environment. The Roadmap also presents criteria to rank research needs. Data for the Roadmap was collected from 2017-2018 and was published in 2018.Item Water Resources Center Annual Highlights, 2019(2020) Water Resources CenterItem Water Resources Center Annual Highlights, 2020(2021) Water Resources CenterItem Water Resources Center Annual Highlights, 2021(2022-01-01) Water Resources CenterItem Water Resources Center Annual Highlights, 2022(2023-01-01) Water Resources CenterItem Water Resources Center Annual Highlights, 2023(2024-02-01) Water Resources CenterItem Water Resources Center Annual Highlights, 2024(2025-02-19) Water Resources Center
