Over the past two weeks, Dr. Charles Humphrey has been working with Guy Iverson (PhD student) and Christa Sanderford (MS Environmental Health student) to oversee a stream bioreactor project in Durham, NC. The reactor should help reduce stream bank erosion and also help reduce nutrient and bacteria transport. The bioreactor installation included excavating 2-3 feet of stream bed and replacing the material with a 1.5 feet layer of wood chips, 6 inches of engineered media that adsorbs pollutants, and then large stones. The reactor is over 200 ft long. Below are pictures showing the installation process of the bioreactor.
