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.
Ballast water - water carried in tanks on ships to help provide stability and aid steering - is likely the single greatest source for introduction of non-native and invasive aquatic species. Ballast water is collected in one body of water and discharged into another body of water, usually large distances apart. At least one new invasive species is found in the Great Lakes every year, with Lake Superior being particularly at risk. Scientists from the U.S.
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 MPCA and used to conduct follow-up investigations at a select number of these sites.
This project will provide a protocol for prioritizing sites in the St. Louis Area of Concern (AOC ) for restoration based on site-specific bioavailability considerations. Despite large data collection efforts focused on sediment chemistry, the extent to which sediment with moderate levels of contamination is available for uptake into biota and therefore contributing to Beneficial Use Impairments (BUI)s is still largely unknown.
The St. Louis River Area of Concern (SLRAOC) conservation partners are focused on removing Beneficial Use Impairments (BUI) in the estuary and eventually delisting the SLRAOC. Cooperative efforts between multiple resource agencies and regional stakeholders have identified a host of restoration objectives, developed project support activities, and partially secured funding that includes a state commitment through the Minnesota Clean Water Fund.

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.
This project will provide technical, planning and engineering assistance to the MPCA for the development and implementation of the St. Louis River Remedial Action Plan (RAP). USACE and USEPA in partnership with the MPCA will administer work plans to complete a sediment assessment for Minnesota areas within Superior Bay, St. Louis Bay, Lower St. Louis River and the Upper St. Louis River, encompassing approximately 5,349 acres of the St. Louis River and Estuary.
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.
This project will use the Spatially Referenced Regression On Watersheds (SPARROW) model as a means of assessing and characterizing the nitrogen loading situation in Minnesota. These results will be used along with other nitrogen loading characterization efforts conducted by others, so that a more complete characterization can be conducted. The results of this effort will be useful as Minnesota works to establish state-specific goals and strategies to address its contribution to Gulf of Mexico hypoxia.
This project will provide an interpretive assessment of nitrogen concentrations in Minnesota rivers and streams, including spatial and temporal trends based on historical data sets. The trends analyses will provide information useful for evaluating nitrogen reduction efforts in the past couple of decades.
The Minnesota Department of Agriculture has partnered with the USDA National Agricultural Statistic Service (NASS) and University of Minnesota researchers to collect information about fertilizer use and farm management. Partners have pioneered a survey tool for characterizing fertilizer use and farm management on a regional and statewide scale. Surveys are conducted over the phone. NASS staff are highly skilled at obtaining critical information over the phone with minimal time and burden on the producer.
This project will improve water management in the State of Minnesota. The result will be a water management tool that can be used by the Minnesota Pollution Control Agency (MPCA) to determine low flow statistics when establishing permit discharge limits and by the Minnesota Department of Natural Resources (MDNR) to help in water appropriations and permitting. This tool will also be used by watershed districts in understanding and quantifying the State's water budget, the Nature Conservancy in its Ecological Limits of Hydrologic Alteration (ELOHA) process, and the U.S.
