This project addresses the treatment of stormwater runoff with tree filters. The major objective of this research project is to investigate the bacteria and petroleum hydrocarbon, particularly polycyclic aromatic hydrocarbon (PAH), removal efficiency of a conventional tree filter and then directly compare it with that of a second, innovative tree filter system. Besides a strong field test component, this project includes detailed laboratory experiments that investigate the permanent fixation of bioactive amendments to strong sorbents. Together, these enhancement, once installed in a tree filter, promise to greatly enhance the sorption capacity for hydrophobic pollutants and the reduction of bacterial load from the stormwater infiltrating into the modified tree filter. Field testing of these filters will be conducted on the Rhode Island Stormwater Treatment Demonstration Facility (RI STDF). |
