The occurrences of contaminants including antibiotics, other pharmaceuticals, and personal care products in the environment have gained increasing attention in recent years because of their potential health and ecological impacts. However, serious gaps remain in our understanding of these contaminants and the significance of the threats they may pose, such as to drinking water. Through this appropriation scientists at the University of St.
A cooperative study was conducted by the U.S. Geological Survey (USGS), the Metropolitan Council, and the Minnesota Department of Health to assess groundwater and surface-water interactions in lakes in the northeast Twin Cities Metropolitan Area (TCMA), including White Bear Lake. An important product of the study was the creation of a groundwater-flow model focused on the northeast TCMA. The groundwater flow model is available for future use to assess the effects of groundwater withdrawals on lake levels as well as to describe other groundwater and surface-water interactions.
The MDA partnered with the USDA National Agricultural Statistic Service (NASS) and University of Minnesota researchers to collect information about fertilizer use and farm management. Surveys were conducted over the phone. NASS staff are highly skilled at obtaining critical information over the phone with minimal time and burden on the producer.In 2011, the survey focused on the southeast region of Minnesota. The survey was designed to gather information about nitrogen fertilizer rates, timing of nitrogen application and use of nitrogen inhibitors.
Four stream segments, totaling over 100 miles, are impaired in the Little Fork River for Total Suspended Solids (TSS) and this study will provide local partners with project options for reduction of sediment in the Little Fork Watershed. Through the use of sediment fingerprinting determinations can be made if the sediment is from in or near channel, or the watershed and identify what sub-watershed the sediment is coming originating.
The Little Fork River and Big Fork River - USGS FLOWSED project was established to collect site specific data for streamflow, SSC, and bedload at the Littlefork and Big Fork Rivers in Northern Minnesota; use the data to evaluate the use of dimensionless sediment rating curves for the rivers; and document the results of the study in conjunction with the results from other rivers in the state for the application of regional sediment rating curves to rivers in Minnesota.
The study will assess existing phosphorus data records and create a model to explain phosphorus loading into the Red River of the North. Studies have found that the majority of nutrient loading in the stream located in agricultural areas occurs with sediment loading since nutrients are typically bound to sediment particles.
This project will collect real-time parameter data for specific conductance, water temperature, pH, dissolved oxygen, turbidity and stream flow at the United States geological Survey (USGS) gaging stations located at Fargo, ND and Grand Forks, ND on the Red River of the North; and publish the data both on the USGS NWIS website and in the USGS Annual Report.
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.
Effective groundwater management requires accurate knowledge about the water budget, which is the amount of water stored within the system in aquifers and the amount of water flowing through the overall hydrologic system including water flowing at the surface, water flowing from above ground down into aquifers, and water flowing between aquifers below the surface.
