Research for healthier fish

Nate Johnson and two students example sediment samples to test for mercury in the soil

That’s why UMD is working on solutions to reduce the amount of mercury in the sediment.

But removing contaminated riverbeds is expensive and impactful. So Nate Johnson, associate professor & director of graduate studies at UMD Swenson College of Science and Engineering, and his team of students are studying how adding things like activated carbon to the soil can help reduce the amount of mercury that enters the food chain. It’s work that might someday lead to healthier food, healthier lives, and a healthier ecosystem. It’s research for cleaner water.
