An interagency workgroup is developing recommendations for best practices and policies for water reuse in Minnesota. Recommendations will include both regulatory and non-regulatory approaches to successful implementation of water reuse. The workgroup will evaluate current regulations, practices, and barriers, and quantify and determine acceptable health risks associated with water reuse applications. The University of Minnesota is collecting and analyzing field data for use in targeting Minnesota-specific risks.
The goal of this project is to enhance the current version of the Enhanced Expert System for Calibration of HSPF (HSPEXP+) so that it can more easily and quickly be used for hydrology calibration, water quality calibration, generate reports and graphs.
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.
The lab will analyze stable isotopes oxygen-18 and deuterium in water samples collected in streams, lakes, wetlands, groundwater, and point sources. This data can identify primary flow sources under varying flow conditions (low to very high flows). Identifying sources can help identify pollutant sources or locate areas that are in need of protection. For example, you may want to protect an area that contributes cold groundwater to a coldwater fishery. Or it could link a water chemistry impairment to a specific source.
The goal of this project is to develop the guidance needed for water quality parameter evaluation and calibration for Hydrological Simulation Program – FORTRAN (HSPF) applications that utilize the general water quality constituent routines on the land surface to generate loadings of nutrients and organic material for input to water bodies to support dissolved oxygen (DO), nutrient, and algal simulation.
The goal of this project is to finalize the draft Lake Pepin Total Maximum Daily Load (TMDL) Report, issue it for public comment, address comments, and finalize the report. Lake Pepin is impaired by high levels of nutrients that cause excessive growth of algae. High levels of sediment, carried in by major river systems, also affect the lake. The sediment is filling in the lake at a much faster rate than before Minnesota was settled and intensely farmed. Nutrients and sediment are distinct yet inter-related pollutants, and are being addressed in separate TMDL reports.
This project is to update stormwater harvest/reuse best management practices (BMPs) in the Minimal Impact Design Standards (MIDS) calculator. The update will also allow the calculator to utilize Excel files from previous of the tool.
The Minnesota Department of Health (MDH) will conduct water sample analysis and collect data for the Minnesota Pollution Control Agency (MPCA) to meet the requirements of the MPCA’s environmental programs.
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.
This project will assist in assessing the quality of the Mississippi River bordering with Wisconsin in partnership with the Minnesota DNR (MNDNR), the Wisconsin DNR (WIDNR) and the Metropolitan Council of Environmental Services (MCES). Sampling will be conducted in 2016 using water chemistry and biological indicators, using a 5 state strategy recently developed recently with the leadership of the Upper Mississippi River Basin Association. The Minnesota entities will focus their work on the River from St Anthony Falls to the Chippewa River confluence in Lake Pepin.
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.
The contractor will collect and process the necessary files needed to develop a Processing Application Tool for HSPF (PATH) and Scenario Application Manager (SAM) project for 30 HUC 8 watersheds in Minnesota. SAM provides a graphical interface to the Hydrological Simulation Program FORTRAN (HSPF) model applications and expands the state’s investment in HSPF to a broader audience in support of the development of Total Maximum Daily Load (TMDL) studies and Watershed Restoration and Protection Strategy (WRAPS) reports.
The goal of this project is to develop forestry related best management practice (BMP) pollutant reduction/management efficiencies, costs, and management information applicable to Minnesota forests and incorporate these BMPs into the Hydrological Simulation Program FORTRAN (HSPF) model Scenario Application Manager (SAM) tool. By incorporating forestry BMPs into the existing SAM tool, forestry related management scenarios can be evaluated for potential impacts on surface waters and can inform the development of watershed restoration and protection strategies.
The goal of this work order is to enhance the Scenario Analysis Manager (SAM) support tool in order to represent best management practices in a more physically based manner, improve point scenario representation and analysis, and support MPCA with training in the application of the enhanced functionality.
The goal of this work order is to collect and process the watershed specific files needed to create the Scenario Application Manager (SAM) project files to apply the SAM software in selected major watersheds in Minnesota where an Hydrological Simulation Program – FORTRAN (HSPF) model has been developed. This work order will also involve technical support for the SAM users who are applying the SAM projects.
RESPEC will use the Processing Application Tool for HSPF (PATH) to construct the remaining 22 Scenario Application Manager (SAM) projects. SAM assists in understanding watershed conditions, and identifying priority areas and BMPs that will provide the greatest water-quality benefits for each dollar invested. The value of the tool is in its simplification of complex hydrologic and water quality model applications into transparent estimates of the significant pollutant sources in watershed.
The goal of this project is to provide three training sessions for the Scenario Analysis Manager (SAM) software and one training session for the Processing Application Tool for the Hydrologic Simulation Program FORTRAN (HSPF) model.
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.
The final product will be a document of final action for an individual Subsurface Sewage Treatment System (SSTS) that a properly certified Advanced Inspector has reviewed to provide adequate environmental protection in accordance with Minnesota Rules.
MPCA will administer funding to eligible Local Governmental Units to use MPCA-approved Advanced Inspectors to conduct work in accordance with Minn. Rules 7080, 7081, and 7083, which requires proper location, design, installation, use and maintenance of an individual subsurface sewage treatment system (SSTS) with a design flow of 2,500 gallons per day or more that protects the public health, safety, general welfare, and the environment by the discharge of adequately treated sewage to the groundwater. Multiple contracts will be awarded.
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 is for on-going sampling and lab analysis for suspended sediment concentration and bedload at select sites, support for continuous Suspended Sediment Concentration measurement using turbidity and Acoustic Doppler Velocity Meter sensors, and comparison of sampling and laboratory methods for total suspended solids and suspended sediment concentrations. The project provides information for defining sediment loading and movement in streams and rivers to adequately address excess sediment problems in Minnesota water bodies.
The 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 permitting.
Cognizant to the needs of the stormwater community, a group that has engaged in stormwater research at the University of Minnesota (UMN) has developed a research program for the biennium that addresses pressing needs: a stormwater research roadmap and framework for priority needs, research required to improve stormwater pond maintenance, and information transfer related to these needs.
The goal of this project is to develop guidance for water quality parameter evaluation and calibration for Hydrological Simulation Program FORTRAN (HSPF) applications focused on dissolved oxygen (D.O.), nutrient, and algal simulation, along with a demonstration of the guidance by step-by-step application to D.O.-impaired Minnesota watersheds.
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.
