Installing an Iron-enhanced Sand Filter
In collaboration with the University of Minnesota St. Anthony Falls Laboratory, City of Stillwater and MN DNR Waters and Fisheries an iron-enhanced sand filter will be designed. This filter will remove approximately 118 pounds of total phosphorous per year from an area of Stillwater that ultimately drains to the St. Croix River, a national Wild and Scenic River that has a decling water quality trend.
The proposed design will reduce phosphorous from a contributing drainage area of 1,200 acres by harvesting stream water from an offline constructed settling pond. Stream flow will fill the settling pond to a designated elevation above the intake pipe at which time the pump will convey flow into the existing pretreatment cell of the pond. After pretreatment, the stormwater will flow through the vegetated swale, which will be retrofitted with an iron-enhanced sand filter, and discharge back to the tributary stream through a newly constructed outlet structure.
The 20-member BWSR board consists of representatives of local and state government agencies and citizens. Members are appointed by the governor of the state of Minnesota consistent with Minnesota Statutes 103B.101. Board members at the time the grant was made were: County Commissioner Appointees: Quentin Fairbanks; Tom Loveall; Brian Napstad; Soil and Water Conservation District Appointees: Paul Langseth, Louise Smallidge and Bob Burandt; Watershed District or Watershed Management Organization Appointees: Gene Tiedemann, LuAnn Tolliver and Todd Foster; Citizen Appointees: Paul Brutlag ; Gerald Van Amburg; John Meyer; Cities & Townships: Sandy Hooker -Township; Christy Jo Fogarty -Metro City; Keith Mykleseth -Non-Metro City; Agency: Chris Elvrum - Minnesota Department of Health; Rebecca Flood - Pollution Control Agency; Tom Landwehr - Department of Natural Resources; Matt Wohlman - Minnesota Department of Agriculture; Faye Sleeper - Minnesota Extension Service;

(a) $13,750,000 the first year and $13,750,000 the second year are for pollution reduction and restoration grants to local government units and joint powers organizations of local government units to protect surface water and drinking water; to keep water on the land; to protect, enhance, and restore water quality in lakes, rivers, and streams; and to protect groundwater and drinking water, including feedlot water quality and subsurface sewage treatment system (SSTS) projects and stream bank, stream channel, and shoreline restoration projects. The projects must be of long-lasting public benefit, include a match, and be consistent with TMDL implementation plans or local water management plans.
Settler's Glen 5th Addition Iron Enhanced Sand Filter - McKusick Lake and Lake St. Croix Proposed Reductions: 118 lbs/year Phosphorus
This project has resulted in an estimated 118 lbs/yr phosphorus reduction.
The source of additional funds varies from project to project, but generally consists of federal, local and non-public sources.
