Nitrate Results and Trends in Private Well Monitoring Networks 2008-2018

The Minnesota Department of Agriculture (MDA) has been working closely with other state and local agencies on developing regional private well nitrate-nitrogen (nitrate) networks. Homeowner volunteers are the cornerstone of the private well networks. Homeowners collect their own water sample and send it by mail to be tested by a laboratory or a county collaborator using MDA equipment at no cost to the homeowner. This method has been developed from years of collaboration with other state and local agencies through pilot projects testing different methods of collection and sample delivery. The MDA currently coordinates two volunteer nitrate monitoring networks with assistance from other state agency and local partners, the Southeast Minnesota Volunteer Nitrate Monitoring Network and the Central Sands Private Well Network. The two networks are discussed in greater detail below.
