Nutrient pollution affects more than 100,000 miles of rivers and streams, close to 2.5 million acres of lakes, reservoirs, and ponds, and more than 800 square miles of bays and estuaries in the United States. The EPA, USGS, and Blue Legacy International challenged solvers to utilize open government data sources to create compelling, innovative, and comprehensible visualizations that inform individuals and communities on nutrient pollution and inspire them to take action to prevent algal blooms and hypoxia in local watersheds. Below, please find links for the winner and runners up of the 2015 Visualizing Nutrients Challenge.
