The city of Dubuque, IA formed a partnership with the Department of Natural Resources to work with upstream farmers to reduce nitrogen and phosphorous levels in the water, according to the Des Moines Register

The agreement establishes the first use of Iowa’s Nutrient Reduction Exchange, a strategy that relies on the cooperation and incentivization of farmers to reduce phosphorous and nitrate levels in the water. Farmers and the city of Dubuque will invest in cover crops, wetlands, and other conservation practices that improve water quality. 

The Register reported that the city of Dubuque, IA is faced with investing $11 million toward improving water quality through upgrading its wastewater treatment facility to meet new state water quality goals. The city hopes this agreement will reduce the cost of improving water quality by reducing the amount of nitrogen and phosphorous at the source; reducing the burden on cities in paying for and improving water quality.

This agreement is the first of its kind and could provide a blueprint for other Iowa municipalities to collaborate with farmers in their regions to reduce erosion and chemical runoffs. Four other Iowa cities and towns are interested in replicating Dubuque’s deal with their local farmers, according to the Register.
