Abstract : Rocky Mountain Arsenal (RMA)has been used as a facility for numerous military and non-military activities which have resulted in the introduction of both organic and inorganic contaminants into the groundwater. Previous treatability studies at RMA have been directed toward organic contaminants that were of concern to the Colorado State Health Department. Well monitoring at (Rocky Mountain Arsenal) has indicated that certain inorganic contaminants have migrated into the groundwater in concentrations above mandatory or suggested standards. The Waterways Experiments Station (WES) was requested to conduct a literature review and preliminary laboratory treatability studies on other sources of contaminated RMA groundwater. This report presents the results of the laboratory studies on inorganic contaminant removal from RMA groundwater conducted at WES with the literature review and treatability work conducted at RMA included in appendices as noted. The studies conducted at WES included in lime, lime/soda ash, caustic, apatite formation, and activated alumina treatment. Clarifier designs suitable for use with lime, lime/soda ash, and caustic work on modeling of the recommended treatment process is also included. A field scale pretreatment water at RMA. The information obtained from the field scale system will be presented in a separate report at a later date.
