The Center for Water Policy contributed to and edited an article, published in the April 2022 Nelson Issue Brief. The Brief features research that addresses excess nutrient concentrations, mostly nitrogen and phosphorus, in surface water. Nutrient pollution degrades recreational and commercial use of surface waters from Wisconsin to the Gulf of Mexico, largely through blue-green algae blooms. In Wisconsin, phosphorus is the most-regulated nutrient, as nitrogen is often considered more of a threat to human health through polluted drinking water, though it also impacts surface waters.
