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.
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.
The Miller Hill Mall, a regional shopping destination located in the City of Duluth, is the largest contiguous impervious site in the Miller Creek Watershed. The draft Total Maximum Daily Load Study identified heated stormwater runoff as a major contributor to the creek's excessive heat loading problem, which negatively impacts the creek's native brook trout population. The Mall, along with eight other entities in the watershed, was assigned a reduction goal as part of the effort to address the temperature problem in this creek.
This project supports monitoring and assessment activities by MPCA EAO staff and includes lab analysis, equipment, fieldwork, data management, and interpretation expenses associated with monitoring and assessment activities.The ambient groundwater monitoring network describes the current condition and trends in Minnesota's groundwater quality.
The lack of sewage treatment in many small communities in Southeast Minnesota is causing surface water and groundwater pollution. Ten of these small communities will be the target of the technical assistance provided by this project. These communities have community or individual straight pipes which are 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.
The St. Cloud Waste Water Treatment Facility (SCWWTF) is currently conducting long term planning for future biosolids management. The most likely path forward includes dewatering of the digested biosolids, which will produce a supernatant stream with significant phosphorus and ammonia loads that would be returned to the liquids treatment portion of the WWTF. Returning these nutrient loads to the liquids train would result in increases to effluent concentrations, increases in power consumption, or both.
