The Winneshiek County Board of Supervisors on Monday heard from Larry Weber, director of civil and environmental engineering at the University of Iowa regarding the future of Iowa’s statewide water quality monitoring network, which faces uncertainty following state funding cuts.

Jason Vogelgesang, a geophysicist with the Iowa Geological Survey, talks on Oct. 29, 2025, about a statewide scanning process the University of Iowa group is doing for the state legislature and levee districts. By using electricity pulses, IGS can detect anomalies — possibly leaky spots — in Iowa's levees. The novel way IGS has rigged their equipment drastically improves efficiency.

Kate Giannini, program manager at IIHR—Hydroscience and Engineering, has been awarded a Fulbright and will be hosted by Deltares located in Delft, Netherlands for a six-week exchange beginning at the end of December 2025.

The Iowa Geological Survey is undertaking a comprehensive five-year project to survey and assess Iowa's 900 miles of levees using cutting-edge geophysical technology, an important precautionary measure to ensure flood protection is ready for the next natural disaster.

If you ask Cong Wang where home is, you’ll get a complicated answer. Born in northern China, he went to Singapore as an undergraduate, where he earned a BEng degree in engineering science. He came to the United States and the California Institute of Technology for graduate school and earned MS and PhD degrees in aeronautics. He stayed on at Caltech for a postdoc and then as a research scientist — 10 years in all.

For over a decade, a network of water quality sensors managed by the University of Iowa has provided publicly available data about waterways across the state. And while Iowa grapples with a growing water quality crisis fueled by agricultural runoff, state government funding cuts have threatened the network’s future.

Despite continued contamination and nitrate spikes in Iowa’s rivers and streams this year, University of Iowa researcher Elliot Anderson insists that the state’s water quality issues can be solved.

This summer Des Moines residents couldn't water their lawns — not because of drought, but due to nitrate pollution. Now, the very system that monitors Iowa's water quality faces a shutdown. Host Ben Kieffer speaks with director of IIHR Hydroscience and Engineering Larry Weber about the implications if we no longer track water quality and the effort to fund the network of 60 sensors across the state.

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.
