A Pilot-Scale Assessment of Peroxone Oxidation for Potential Treatment of Three Contaminated Groundwaters at the Rocky Mountain Arsenal, Commerce City, Colorado
Abstract
Peroxone technology is based on the combination of hydrogen peroxide (H2O2) and ozone (O3) for the generation of the hydroxyl radical (OH-), which is a powerful reactive species in water, to further oxidize the organic contaminants. The main objective of this study was to determine the technical feasibility of using a peroxone system for treatment of contaminated groundwaters at the Rocky Mountain Arsenal (RMA). Past military and industrial activities at RMA have resulted in the contamination of the alluvial aquifier with various organic compounds such as diisopropylmethyl- phosphonate (DIMP), pesticides, and volatile organic compounds. The U.S. Army Engineer Waterways Experiment Station (WES) has been tasked by the Department of Defense's (DoD) Office of Strategic Environmental Research and Development Program to investigate the potential of peroxone for treating contaminated groundwaters at DoD installations. The peroxone oxidation pilot system used in this study was constructed and assembled by the WES Environmental Restoration Branch and the WES Directorate of Public Works. The unit consisted of four glass columns (6-ft diam and 14 ft in height) plumbed in series, a holding tank (500 gal) for influent water supply, two 3-lb-per-day ozone generators, a microcomputer for data logging, oxidizer injection systems, and monitors for vapor and aqueous phase concentrations of hydrogen peroxide and ozone.
