Abstract : Groundwater at Rocky Mountain Arsenal (RMA) has been found to contain certain organic contaminants as a result of various past and ongoing activities at the arsenal. An initial bench scale treatability study, identified a combined ultraviolet light and ozone oxidation process as having a high-potential for removing the organic contaminants. As a result of this study, a 1000 gpd field unit was obtained on a short term basis and placed in operation at RMA during the summer of 1977 to further assess the potential of the UV/ozone treatment process in removing organic contaminants from RMA groundwater. In this study, the UV/ozone process proved very successful in removing organic contaminants from the particular groundwater tested. The field-scale study was limited in scope by the configuration of the UV/ozone field unit used. The unit configuration did not allow for variable control of certain parameters such as temperature, PH, pressure, and mechanical mixing. These parameters must be evaluated as to their effect on process efficiency for the various source waters at RMA . During the limited field-scale study, three runs were made on water from PW 118 using the ULTROX unit. This work was conducted to determine if any operational problems would occur when treating water with above normal concentrations of iron and manganese. The water from PW 118 was found to contain iron and manganese in a reduced state. (jg) p3
