When it rains, untreated stormwater can sweep pollutants into coastal waters, potentially endangering public health. Now researchers and Cooperative Extension engineers from N.C. State University have developed low-cost filtration systems that are concealed beneath sand dunes and filter out most of the bacteria that can lead to beach closures.
“It was not economically feasible to use a tract of beachfront property to treat stormwater. Instead, we were able to devise a system that could be installed in an area that was not developable – underneath the dunes,” says Dr. Michael Burchell, an assistant professor and Cooperative Extension engineer from the Department of Biological and Agricultural Engineering. Burchell is senior author of a paper on the research.
