A family dairy farm in the shoreland area of Lake Miltona has a liquid manure storage area that is not up to standards due to sandy soil and a high water table, increasing the likelihood of groundwater contamination. Lake Miltona is connected to the Alexandria Area Chain of Lakes and ultimately the water ends up in the Long Praire River. Groundwater impacts to the Long Prairie River have the potential to be significant.
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.
This project will protect the groundwater and the city of Princeton's drinking water from nutrient contamination associated with livestock manure storage. Well water tested throughout Mille Lacs County, and specifically within the Anoka Sand Plain area of Princeton, routinely indicate the presence of nitrates in shallow drinking water wells.
Private wells provide drinking water for the rural residents of Lac qui Parle County. This project will retrofit 35 well pits allowing the homeowner to continue using a serviceable well while safeguarding the source of their drinking water. Well pits, which are similar to a below-ground cistern, were once a common practice to prevent freezing in the winter. Many of these pits remain in use today. However, well pits are subject to flooding, especially if they are located in a floodplain. Flooding can contaminate the well and groundwater with bacteria from unknown sources.
