It’s designed to direct efforts to reduce nutrients in surface water from both point and nonpoint sources in a scientific, reasonable, and cost-effective manner. The strategy outlines a pragmatic approach for reducing nutrient loads discharged from the state’s largest wastewater treatment plants, in combination with targeted practices designed to reduce loads from nonpoint sources such as farm fields. This is the first time an integrated approach involving both point sources and nonpoint sources has been attempted.
Iowa farmers and cities have accepted the new challenge of reducing nutrients in Iowa’s surface waters. In 2018 the Iowa Legislature established a dedicated, sustainable funding source totaling more than $270 million to be used through 2029 for the Iowa Nutrient Reduction Strategy and its Water Quality Initiative implementation program for rural and urban nutrient reduction efforts.
