Duluth area streams received over 10 inches of rainfall on June 19 and June 20, 2012. This "500 year event" provides a once in a lifetime opportunity to further understand sediment movement and stream channel alterations due to an event of this magnitude.
This project will determine the magnitude and frequency of contamination from endocrine active compounds (EAC's) and other contaminants of emerging concern in shallow groundwater in non-agricultural areas of Minnesota. EACs and other contaminants of emerging concern in this study include compounds typically found in waste water, including, pharmaceutical compounds, antibiotics, and hormones. This project supports the third phase, including laboratory analysis of samples for an additional 80 wells to be sampled by MPCA staff.
Groundwater sample collection and analysis will be conducted for contaminants of emerging concern (CEC) at large subsurface treatment systems (LSTS) and rapid infiltration basins (RIB), using an enzyme linked immunosorbent assay (ELISA) methodology. Results from the ELISA analysis will be reported to the Minnesota Pollution Control Agency (MPCA) and used to conduct follow-up investigations at a select number of these sites.
The stream monitoring will follow the stream monitoring parameters and frequency tables outlined in the Surface Water Assessment Grant (SWAG) Request for Proposals (RFP). Specifically over the two-year grant period, monitoring will include 19 sets of field measurements for specific conductance, temperature, pH, dissolved oxygen, secchi tube readings, and one upstream photograph at each visit.
This project will develop a reasonable statewide estimate of recharge using the Soil-Water-Balance (SWB) Code (Westenbroek and others, 2010), validate the simulation results, and conduct a parameter sensitivity analysis to identify the most sensitive model parameters. For the purposes of this application of the SWB application, comparing the simulation results will be conducted on selected watershed basins in the state against previously established recharge estimates.
The objective of this project is to 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 and Grand Forks North Dakota.
This Partnership Agreement is a 5-year effort that will provide the technical, planning and engineering assistance for implementation of the 2013 St. Louis River Area of Concern Remedial Action Plan. Through this agreement the U.S. Army Corps of Engineers and MPCA will develop detailed work plans and construction design plans for numerous sites in the project AOC and assist with critical AOC-wide issues.
• 21st Avenue West Restoration Site. Outcome will be preliminary to final engineering designs and costs ready for bid package development.
• Knowlton Creek Site.
The Statewide Sediment Network was established to measure the levels of suspended sediment concentrations and particle size distributions at eight sites across Minnesota to evaluate the amount of sediment carried by rivers. USGS sample collection and laboratory analysis techniques provide a more rigorous, robust, and technically accurate measure of sediment in water than the current use of total suspended solids as the measure of sediment in water.
Zebra mussels are an aquatic species that are invasive in Minnesota and severely threaten native fish and other aquatic species by disrupting food webs and damaging spawning habitat. Their range continues to expand within Minnesota lakes and rivers, where they are spread through the transporting of water, vegetation, or equipment from an infested water body. Once established zebra mussels are very difficult to control and there is an immediate need for safe and effective control measures to reduce their impacts in the state.
