This project proposes significant improvements to the City of Bloomington's Anti-Icing/Brine making capabilities. The use of anti-icing technology reduces the amount of salt needed to clear snow and ice from city street. The improvements work to address the chloride impairment in Nine Mile Creek and the metro area by reducing the amount of salt applied to the streets and thereby reducing the amount of chlorides entering our surface water systems.
Once thought to have an essentially inexhaustible groundwater supply, Minnesotans are now realizing our rates of use are regionally unsustainable. Recent advanced modeling by the MN DNR and Metropolitan Council of aquifer supplies, in conjunction with predicted demand, indicate the major metropolitan area aquifers are currently subject to extraction rates that exceed recharge. Simply stated, we are mining our groundwater.
Carver County has identified water quality improvement of Carver, Bevens and Silver Creek as a water management priority. This project will identify storage or wetland restoration sites that are highly effective at reducing pollutant loading to downstream impaired waters using high-resolution Light Detection and Ranging (LiDAR) data and Geographic Information System (GIS) processes. The watershed landscape has been highly modified for agricultural production land development; less than 50 percent of pre-settlement wetland acres remain in Carver County.
The Drinking Water Contaminants of Emerging Concern (CEC) program identifies environmental contaminants for which current health-based standards currently do not exist or need to be updated, investigate the potential for human exposure to these chemicals, and develop guidance values for drinking water. Contaminants evaluated by CEC staff include contaminants that have been released or detected in Minnesota waters (surface water and groundwater) or that have the potential to migrate to or be detected in Minnesota waters.
The Keller Lake Water Quality Improvement Project achieves the goals of the City of Burnsville, Black Dog Watershed Management Organization, and the Keller Lake TMDL by:-Achieving the City of Burnsville phosphorus removal requirement outlined in the Keller Lake TMDL by removing 78 lbs/yr-Utilizing remaining available land to construct a high performance, regional stormwater BMP-Providing a high profile water resource/stormwater educational opportunity in the frequently visited Crystal Beach Park-Retaining valuable open space in popular Crystal Beach Park by constructing the BMP undergroundK
Lake Augusta and Sunfish Lake are deep lakes located in the Lower Mississippi River Watershed Management Organization. Both lakes are approximately 40 acres in size and surrounded by watersheds with moderate to low imperviousness. Both lakes are included on the MPCA's 303(d) list as impaired for aquatic recreation due to excessive nutrients. Lake Augusta and Sunfish Lake were included in a watershed restoration and protection strategies (WRAPS) study and total maximum daily load (TMDL) performed from 2012 to 2014.
Nicollet County is located in south central Minnesota and is bordered on two sides by the Minnesota River. A line of forested bluffs separate the river valley from land that is relatively flat and historically used for agricultural purposes. Approximately 245,000 acres of the County are actively farmed. The 2012 impaired waters list for water bodies located in Nicollet County include the Minnesota River, Seven Mile Creek, Rogers Creek and tributaries to the Rush River.
Approximately 70 percent of all Minnesotans rely on groundwater as their primary source of drinking water. Wells used for drinking water must be properly sealed when removed from service to protect both public health and Minnesota’s invaluable groundwater resources. The Minnesota Department of Health protects both public health and groundwater by assuring the proper sealing of unused wells.
Clean Water funds are being provided to well owners as a 50% cost-share assistance for sealing unused public water-supply wells.
