This project will obtain spatial and long-term pollutant load information from the Root River watershed in Southeast Minnesota. To accomplish this, the Fillmore Soil and Water Conservation District (SWCD) will assist the MPCA with water quality monitoring and annual pollutant loading calculations. Approximately 25 grab samples will be collected/site/year at 5 sites within the Root River watershed (totaling 125 grab samples/year). Annual load calculations for each site will be determined using the FLUX32 model.
The Winona County Soil and Water Conservation District (SWCD) developed this project to help reduce the amount of pathogens and nutrients generated by livestock from reaching surface waters and groundwater by targeting feedlots located in areas that are highly susceptible to groundwater pollution and sinkhole formation.
Peer Engineering, Inc. (Peer) will evaluate and recommend to MPCA groundwater monitoring staff prospective sites/locations for the installation of groundwater monitoring wells to evaluate contaminant/pollutant concentrations from various sources. Peer will oversee the installation of monitoring wells by retaining a state drilling contractor or preparing bid documents to retain well driller through the Department of Administration. Superfund staff will assist in the project by providing oversight of contractual requirements and provide technical assistance as needed.
This project will build network and the skill set of local resource professionals to do effective civic engagement work for water restoration and protection in Southeast Minnesota. The cohort will be administered through the Southeast Minnesota Water Resources Board (SE MN WRB) which is an area wide Joint Powers Board (JPB) established to help improve and protect the water resources of the area through coordinating local water planning efforts. This JPB has successfully administered water quality grants in the past that have positively impacted the water resources of this region.
This project will identify and compile existing nitrate data from groundwaters and surface waters in the Lower Mississippi Basin (LMB) generally and focus on the Root River Watershed. The purpose is to investigate the quantity and quality of existing nitrate data, and to organize it for use in comprehensive watershed strategy development (including assessment, TMDL computation and identification and study of nitrate sources and delivery mechanisms).
LEQA is a Minnesota Department of Agriculture (MDA) program to help livestock producers address, using a non-regulatory approach, the unique water quality issues on their farms. The MDA has contracted with Ag Resource Strategies, LLC, to recruit farmers to enroll in the LEQA program. The company trains technicians to assess different areas of each farms, such as the farmstead, livestock facilities, fields and wooded areas. The technicians then develop an environmental assessment and identify financial assistance for these projects.
Ninety percent of the land in Mower County is used for agriculture. The County ranks 10th and 13th in the State for corn and bean production, making much of the land vulnerable to erosion due to the planting of row crop. As a result, streams and ditches in the county see high sediment loads.
Regionally, nitrate nitrogen concentrations are continuing to increase in both surface water and ground water based on monitoring data. The increasing trends are thought to be attributable to over application of manure and commercial nutrients on row-cropped fields. In order for nitrate concentrations to decrease, nutrient management is needed throughout the basin. Two nutrient management specialists will assist landowners in the eleven-county Southeast Minnesota Area with writing nutrient management plans and implementing conservation practices for manure and fertilizer use.
TMDL project in the Root River Watershed that will support surface water assessment, analysis of data, interpretation of southeast Minnesota's karst landscape, stressor identification, TMDL computation, source assessment, and implementation planning.
The lack of sewage treatment in some small communities in Southeast Minnesota is causing surface water and groundwater pollution. Fourteen of these communities will be the target of the technical assistance provided by this project. These communities have community or individual straight pipes discharging raw sewage directly into the environment;surfacing sewage or have sewage contaminating groundwater.
The goal of this project is to investigate nitrate transport and the sources of nitrate in karst for more effective implementation of best management practices that will reduce nitrate concentrations in ground and surface water.
