The Iowa Learning Farms webinar on Wednesday discussed the progress that has been made by Iowa’s municipalities and industries toward reducing point source pollution reaching Iowa’s waterways. Adam Schnieders, water quality resource coordinator with the Iowa Department of Natural Resources (DNR), shared information about the progress to date, after eight years of implementation.
Iowa’s largest communities and industries have a significant role to play to help meet the state’s nutrient reduction goals. Understanding that role and the progress to date paints a clearer picture of how the many facets of Iowa’s Nutrient Reduction Strategy fit together and work today. Schnieders shared some background information about how far Iowa has come in terms of water quality, and the importantce of wastewater treatment facilities integrating nutrient removal technology into their operations.
The data from 1992 to 2013 in the chart above is an estimate that is based on population growth and increased flow at the wastewater treatment facilities. With the finalization of the Iowa Nutrient Reduction Strategy, total nitrogen and phosphorus annual load began to be measured at the facilities. Although there appears to be a sharp increase after 2013, this is likely due to the limitations of the previously estimated loads. Now that the loads are being measured, progress toward the goals of the strategy can also be measured.
