One of the U.S. Geological Survey teams collecting water samples and checking cages for fish eggs in Missouri this summer: biologist Diana Papoulias, chemist Dave Alvarez, hydrologist Peter Van Metre, biologist Diane Nicks and environmental toxicologist Don Tillitt.
Midwest waterways are getting lots of attention this summer. Scientists from the U.S. Geological Survey and the Environmental Protection Agency have immersed themselves in the ecology of 100 streams from Ohio to Nebraska. It’s a first-of-its kind effort to understand how ag runoff is not just changing the water but affecting the critters that live there. Harvest Public Media’s Abbie Fentress Swanson joined a crew on a rainy day while they gathered water samples and searched for fish eggs on three streams in central Missouri.
