The primary goal of this project is to analyze of dated sediment cores to reconstruct changes in the lake condition over the last 150 years. This will be done using multiple lines of evidence including biogeochemistry, sediment accumulation, and diatom and algal remains as biological indicators.
The Clay County Drainage Site is designed to evaluate the environmental impact of both surface and subsurface drainage from agricultural fields. This site includes six subsurface plots and one surface runoff plot, each approximately 24 acres in size. Monitoring stations are fully automated and each individual plot is monitored separately.The soils and topography across this demonstration site are virtually identical and represent field characteristics common in the most productive agricultural areas of the Red River Valley.
The goals of the program are to evaluate the effectiveness of agricultural conservation practices, identify underlying processes that affect water quality, and develop technologies to target critical areas of the landscape. Funded projects provide current and accurate scientific data on the environmental impacts of agricultural practices and help to develop or revise agricultural practices that reduce environmental impacts while maintaining farm profitability.
The Discovery Farms program is a farmer-led effort to gather information on soil and nutrient loss on farms in different settings across Minnesota. The mission of Discovery Farms Minnesota is to gather water quality information under real-world conditions.
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.
Concern for Deer Yard and Poplar lakes centers on their current trends of decreasing water transparencies often associated with phosphorus or sediment increases. Although both lakes still meet nutrient goals, trends in Secchi depth may presage emerging issues with the state of the lakes. This has further led to questions whether the productivity of the lakes have changed over time, what the natural or historical condition of the lakes were, what the current trajectory of each lake is, and how to best set management goals.
The objective of this project is to build on previous efforts aimed at determining the public health risk due to virus contamination in Minnesota groundwater. The Minnesota Department of Health will examine the occurrence of viruses in non-disinfecting groundwater sources in Minnesota as well as evaluate the association between source water virus occurrence and community acute gastrointestinal illness.
Staffing support to evaluate the performance of existing stormwater infiltration sites, as identified in the Minimal Impact Design Standards (MIDS) project. Monitor the range of existing infiltration devices in Minnesota and compare to design criteria, maintenance records, and quantify year-round infiltration rates. Develop and refine pretreatment options and standards for municipal stormwater treatment.
The goal of this project is to better target restoration activities in the Cannon River watershed via a paleolimnological study of a selected set of the lakes addressed in the Total Maximum Daily Load (TMDL) for the watershed. The goals are to better constrain lake phosphorus budgets, and determine the magnitude of ecological change experienced by a range of lake types.
Arsenic occurs naturally in soil and minerals and is commonly found in groundwater throughout much of Minnesota. The occurrence and distribution of arsenic in groundwater is difficult to predict. Research is steadily increasing our understanding of the mechanisms and geologic conditions that determine arsenic occurrence in groundwater. The arsenic concentration in a new well, measured at the time of construction, is sometimes higher or lower, compared to subsequent sampling results.
The Root River Field to Stream Partnership is comprised of farmers, the Minnesota Department of Agriculture, the Minnesota Agricultural Water Resource Center, The Nature Conservancy, Fillmore and Mower County Soil and Water Conservation Districts, the Root River SWCD, Monsanto and academic researchers.Together, project partners are addressing the following key questions:What is the range of sediment, nitrogen and phosphorus losses from agricultural fields on real farms in southeast Minnesota?What are the long-term trends and relationships between specific farming practices and water qualit
The goal of this project is to update and revise the Twin Cities Metro Area (TCMA) Chloride Management Plan to a Statewide Chloride Management Plan (CMP). The Statewide CMP will provide stakeholders the information and tools necessary to improve and/or maintain water quality with respect to chloride.
The goal of this project will be to research and develop statewide winter maintenance best management practices (BMPs) for inclusion in the Statewide Chloride Management Plan and Winter Maintenance Assessment tool (WMAt). The WMAt is a necessary technical resource and planning tool for stakeholders and permittees to implement the chloride reduction strategies described in the Statewide Chloride Management Plan.
This project will conduct on-going sampling and lab analysis for suspended sediment concentration at select sites. It will also develop real-time continuous suspended sediment concentration measurements using turbidity and Acoustic Doppler Velocity Meter sensors, data analysis and draft United States Geological Survey (USGS) Scientific Investigations Report, and comparison of sampling and laboratory methods for total suspended solids and suspended sediment concentrations.
The goal of this project is to maintain and make enhancements to the Winter Maintenance Assessment tool (WMAt), which is a necessary technical resource and planning tool for stakeholders and permittees to implement the chloride reduction strategies described in the Chloride Management Plan.
