Researchers will gather water quality information from Upper Mississippi River basin states.
Oxbow Restorations Benefit Habitat, Ecosystem
Oxbow restorations provide wildlife habitat for creatures that like these quiet backwaters, and they also process nutrients. And they’re surprisingly affordable.
Safe Drinking Water for Iowans
Scientists at IIHR are working with municipal water supply operators in several Iowa cities to help bring safe and reliable supplies of drinking water to those communities.
IIHR Water-Quality Monitoring Network
Is water quality in Iowa an invisible problem? The risks to human health are significant and costly. According to the U.S. Environmental Protection Agency (EPA), high levels of nitrates in drinking water are especially dangerous for babies, pregnant women, and nursing mothers. Cities such as Des Moines are investing in expensive nitrate-removal systems to make […]
Water-Quality Monitoring Sensor Network
IIHR’s water-quality initiative represents an unprecedented effort to monitor real-time changes in a large river in response to climatic events, agricultural trends, and other human activities. Researchers at LACMRERS have 10 Hydrolab multi-sonde water-quality monitors deployed in Pool 16 for detailed chemical analysis. The sensors provide continuous real-time monitoring of: Dissolved oxygen Temperature Specific conductance […]
PCBs: Dredging Up a Problem
For more than a century, toxins generated by heavy industry settled to the bottom of the Indiana Harbor and Ship Canal (IHSC) in East Chicago, Ind., creating thick sludgy mud that is home to everything from heavy metals to polychlorinated biphenyls (PCBs). The U.S. Army Corps of Engineers has announced plans to dredge the canal, but the plan raises questions for scientists.
Boat Safety Guidelines
by Douglas J. Schnoebelen, LACMRERS Director Introduction River and lake research for hydrologists, geologists, engineers, biologists, and other scientists often involves the use of boats under a variety of conditions. In particular, scientists from the University of Iowa’s IIHR—Hydroscience & Engineering and the Lucille A. Carver Mississippi Riverside Environmental Research Station (LACMRERS) routinely depend on […]
Learning from the River
