A new state project is expanding to track nitrogen levels in the soil in four counties north of Cedar Rapids. Farmer Caleb Hamer of Traer is already working to keep nitrates from his land out of the Cedar River. He has worked with Cedar Rapids and the University of Iowa on various projects, including the Iowa Flood Center’s hydrostation network and a saturated buffer project that acts as a filter.

Iowa City West High School senior Kento Sugiyama is applying his interests and aptitude in mathematics, science, and web-based technologies to real-world challenges, working to make a difference for people and communities facing natural disasters.

Several different government agencies and nonprofits came together to contribute to new IIHR water quality sensors that would monitor the water quality in Dubuque County.

New research from the U.S. Geological Survey shows nutrient pollution increased in many streams and rivers across the country between 2000 and 2020. The dominant source was the release of old nitrogen and phosphorus stored in soil and groundwater.

Water quality was top of mind inside a packed conference room at a Dubuque County Supervisors meeting at the Northeast Iowa Community College on August 12.

The University of Iowa’s new program, the Iowa Integrated Network for Science, Information, and Geospatial Health Tracking (INSIGHT), has announced that a group of distinguished national experts will serve on its advisory board.

Nutrients in Iowa’s waterways and their likely impact on state’s high cancer rates were a topic of discussion at a seminar this past weekend during the Boji Cleanwater Jam in the Iowa Great Lakes.

A seminar at the Boji Cleanwater Jam focused on nitrate in Iowa’s waterways and its potential impact on cancer rates. Larry Weber, director of IIHR at the University of Iowa, gave an update on IIHR’s network of about 80 nitrate monitoring sensors deployed around the state and the rising nitrate levels recorded.

The Boji Clean Water Jam brought together community members, environmental experts, and musicians for a weekend focused on water quality issues affecting Iowa. IIHR Director Larry Weber addressed expanding environmental monitoring and forecasting systems.
