Results of a study show the Illinois River is getting cleaner.

Scientists at the Urbana campus of the University of Illinois say the reduction in the amount of nitrogen released into the river from Chicago and runoff from some farm fields represents a new milestone.

Greg McIsaac (MICK-eye-sick) serves as one of two U-of-I researchers measuring progress on a statewide effort to improve water quality;

Illinois adopted a statewide Nutrient Loss Reduction Strategy last year. Its ultimate goal is to help reduce the so-called dead-zone in the Gulf of Mexico caused by wastewater, excess fertilizer and other chemicals.

McIsaac describes the role of rural Illinois and the study’s results.
