A plan for $600,000 in necessary funding to maintain a University of Iowa water monitoring system vital for tracking nitrate, dissolved oxygen, and pH rates in streams across the state is set to be discussed in a meeting Friday between Johnson County and Polk County officials.

Sixteen scientists compiled 50 years of data on the Des Moines and Raccoon rivers, two of the largest sources of drinking water for Des Moines and Polk County. The study found that pollutants have increased by nearly 100 percent in the last 50 years, and researchers say not enough is being done to address the issue.
