Minimize the risks of threats to public health through the development of programs, plans and policies that improve the quality of surface and groundwater resources.
Threats to public health in the Minnehaha Creek subwatershed relate to pathogens found in the waters. Sewage overflows from sanitary sewer breaks or improperly functioning infrastructure could result in overflows discharged to downstream water resources. An additional potential source of pathogens is waterfowl, which are attracted to open water with easy routes from the water to vegetation on shore. The Minneapolis Park Board monitors beaches on the lakes in Minneapolis and manages necessary closures when bacteria counts exceed state health standards. Ongoing monitoring in Minnehaha Creek has found periodic e. coli exceedances in the Creek. The District’s role in minimizing risks to public health will be to continue monitoring the Creek to diagnose potential sources for those exceedances and to develop a plan for addressing them.
Desired Outcomes: Minimization of threats to public health from contact with contaminated surface waters.
Metrics: Reported cases of illness transmission via surface water contact.
Minimize risks to human health and water quality from land use activities.
Maintain a vegetated shoreline on lakes, streams and wetlands where practical and effective to reduce overpopulation with waterfowl.
Require LGUs and other agencies to manage public sanitary sewer infrastructure to minimize sewage overflows and to minimize impacts from those overflows on District water resources.
