Scientists at the University of Illinois Urbana-Champaign can now differentiate between human-derived and hydrological contributions of riverine nitrogen pollution in the Upper Mississippi River Basin. The advancement, recently published in Environmental Science and Technology, sets the stage for more nuanced policy and management of nitrate and nitrite, the nutrients that degrade drinking water quality and cause oxygen-starved “dead zones” in the Gulf each year.
