University of Iowa researchers are studying the role freshwater mussels play in the nitrogen cycle as a way to improve water quality in the Hawkeye State.

Craig L. Just – an assistant professor of civil and environmental engineering – and Ellen Black – PhD candidate in Environmental Engineering and Science – are studying the potential of using freshwater mussels as a way to remove nitrogen from Iowa waterways. Nitrogen contributes to the growth of algae which serves as a food source for the mussels. Specially, Black is looking at the effect that microbial communities have on native freshwater mussels.

“Mussels filter water and excrete nitrogen into underlying sediment, thus sequestering biologically active nutrients for microorganisms to consume and possibly remove from river systems,” Black told The Daily Iowan.

Through the use of generation sequencing, Black is able to pinpoint all bacteria found in mussel beds which can help researchers to better determine the effect that mussels have on microbial processes.

In addition to his work with mussels, Just has also worked with civil and environmental engineering PhD candidate Hunter Schroer. Just and Schroer are studying ways to make military explosives less prone to self-detonation. The researchers also seek to discover and potentially mitigate the impact that explosives have on the environment by finding organisms that detoxify explosives by converting them into carbon dioxide. They’re also studying ways they can use plants as a cost-effective way to detect explosives in soil.

  1. Freshwater mussels are very sensitive to water pollutants including excessive nitrogen. Thinking that mussels can help Iowa’s widespread water quality problems and especially nitrogen is impractical.
    Better to use scarce research money on legitimate means to reducing the pollution.

  2. If you can find factual evidence that fresh water mussels make the water quality better. Than do it. Iowa water taste Horrible.
