The Nature Conservancy (TNC) is constructing and restoring wetlands in agricultural watersheds of the Mississippi River. A primary objective is to reduce pollutants including nitrate-nitrogen in leachate and runoff to local waterways while increasing water storage. A larger goal is to reduce nitrogen loads in the Mississippi River and Gulf of Mexico where nutrient enrichment contributes to algal blooms and hypoxia. The wetlands are generally located in low lying areas that are not well-suited for planting. Water drains to the wetlands through tile drains or surface runoff where it is retained to reduce nutrient and sediment loads. This treatment is not required by law. Contamination due to agricultural runoff is a long-term problem in tributaries to the Mississippi River. Nitrogen concentrations continue to increase within Mississippi River and its tributaries and high concentrations of nitrate are common in private wells and some public water supplies. Approximately 211 million pounds of total nitrogen flows out of Minnesota each year into the Mississippi River, over _ from Minnesota tributaries. (MN Pollution Control Agency 2013). Who is TNC and TNCÕs Principles of Corporate Engagement The Nature Conservancy is a global conservation organization dedicated to conserving the lands and waters on which all life depends. Guided by science, we create innovative, on-the-ground solutions to our world's toughest challenges so that nature and people can thrive together. We are tackling climate change, conserving lands, waters and oceans at unprecedented scale, and helping make cities more sustainable with ambitious 2030 goals. Working in more than 72 countries, we use a collaborative approach that engages local communities, governments, the private sector, and other partners. To learn more, visit www.nature.org.
