- W283334240 abstract "Abstract : Rocky Mountain Arsenal (RMA) has been a chemical manufacturing and chemical demilitarization facility since 1942. Wastes from various chemical processes were discharged into unlined basins until construction of an asphalt-lined evaporation lake was completed in 1955. Repeated contact of rainwater and groundwater with chemical wastes in and beneath the basins has resulted in transport of chemical compounds toward the boundaries of RMA. The groundwater at RMA is known to be contaminated with chlorinated hydrocarbons, organophosphorous, organosulfur, and other organic compounds. The purpose of this investigation was to determine the feasibility of using ultraviolet/ozone (UV/O3) treatment to reduce the concentration of those contaminants in the RMA groundwater. This report discusses the experimental results obtained from treating RMA groundwater with UV light and ozone. The laboratory investigations used two different batch reactors and varied such parameters as ozone concentration, temperature, and wattage of UV light. Continuous flow experiments were also conducted. In batch experiments, total organic carbon removal ranged from 40 to 90 percent. The concentrations of diisopropylmethylphosphonate (DIMP) and other organic compounds were significantly reduced. In the continuous flow phase of the study, it was possible to remove 93 percent of the DIMP originally present and lower the levels of all other organic contaminants to below detectable limits.
