Freshwater, the University of Minnesota Water Resources Center, and Rice Creek Watershed District are partnering to offer more education and collaborative opportunities to explore the nuances of iron-enhanced sand filter system maintenance, operations, and design. We are doing this through site visits and an in-person workshop to further collective understanding among practitioners, researchers, and decision makers.
