Hypoxic dead zones found in urban streams, not just at the coast


December 11, 2018

A Duke University-led study finds that hypoxic dead zones occur in nutrient-laden urban streams, not just in coastal waters. The research shows that intense storm flows can erode some stream channels to become a series of pools that trap nutrient-laden runoff.
