Project partners play a vital role in the implementation of the Verdi Wellhead Protection Plan and have made this water source a priority in lowering nitrate levels. The aquifer used by the wells in the Verdi Well Field consists of a sand and gravel horizon about 30' thick which overlies clay-rich till. The geological sensitivity in all five of the Verdi wells is classified as "high".The Verdi Well Field supplies water to ten community water suppliers, 34 large rural users, and 1,126 rural hookups. Total population served by this water supply is about 7,500.
Agricultural drain tiles with surface intakes are considered a significant delivery mechanism of nutrients to Minnesota River. Protecting those surface water inlets can reduce the direct path those nutrients have to the river. In addition, in agricultural fields with subsurface drainage, leached nitrate creates elevated nitrate levels in tile drainage water. These high nitrate concentrations can cause algae blooms that remove oxygen. To help remove nitrates leached into tile drains, wood chip bioreactors can be installed to remove nitrate from the tile water before it enters surface water.
Project will focus on BMP's that reduce runoff and/or keep water on the land. The establishment of 8 native plantings on 153 acres using an approved 15 native species mix on marginal farm fields will significantly reduce runoff of sediments and nutrients, and act as a filter to remove nutrients and sediment from fields upslope. Based on RUSLE2 estimates, 336.6 tons/yr of soil will be saved, and 202 lbs/yr of phosphorus and 3,336 lbs/yr of nitrates will not runoff the fields and/or leach into the ground water.
The DNR works with the Minnesota Geological Survey (MGS) to convey valuable geologic and groundwater information and interpretations to government units at all levels, but particularly to local governments, private organizations and citizens. The MGS focuses on geology (Part A reports) and DNR focuses on groundwater (Part B reports). These provide useful information for projects completed by community planners, industry, agriculture, citizens and state agencies related to groundwater.
A large portion of Otter Tail County has been identified as being susceptible to groundwater contamination from nitrates and other water soluble contaminants. Agriculture is the predominant land use activity in this area. Irrigation in the county has increased in the last few years. With the vast majority of the residents getting their drinking water from groundwater sources, protecting ground is a priority for the county.
Per Minnesota Law, the Minnesota Humanities Center administers a competitive Arts and Cultural Heritage Grants Program-Councils of Color. The Humanities Center uses a portion of the funds to provide grants administration, including releasing an RFP, overseeing the proposal process, coordination of the independent review panel, agreement drafting, financial and program monitoring, and reporting.
