2017 CWF South Branch Vermillion River Nitrate Treatment Project
As part of the Dakota County Transportation Department's highway 78 road reconstruction project, the Vermillion River Watershed Joint Powers Organization is partnering with Dakota County to install a nitrate treatment practice on a tributary to the South Branch Vermillion River adjacent to the road. The South Branch Vermillion River subwatershed is the highest nitrate loading subwatershed in the Vermillion River Watershed and is a significant contributor to contaminated drinking water in the eastern portion of the watershed. The project will result in the installation of a constructed wetland with enhanced soil media adjacent to County Road 78.
$10,187,000 the first year and $10,188,000 the second year are for grants to protect and restore 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 projects and stream bank, stream channel, shoreline restoration, and ravine stabilization projects. The projects must use practices demonstrated to be effective, be of long-lasting public benefit, include a match, and be consistent with total maximum daily load (TMDL) implementation plans, watershed restoration and protection strategies (WRAPS), or local water management plans or their equivalents. A portion of these funds may be used to seek administrative efficiencies through shared resources by multiple local governmental units.
13,600 pounds of nitrogen/year
The constructed wetland with enhanced soil media was installed and constructed underbudget. The JPO was approved for a work plan revision to utilize some of the grant funds remaining to also install a woodchip bioreactor for nitrate treatment. Both projects were constructed well under the anticipated grant budget. Volume reduction of 556 ACRE-FEET/YR., Nitrate reduction of 13925 pounds/YR., Sediment (TSS) reduction of 7.6 TONS/YR.
