Abstract : As part of an overall north boundary containment system the Project Manager's Office has outlined program tasks to be performed. These tasks seek to solve the problem of contaminates migration across the north boundary at Rocky Mountain Arsenal, and thus address the Cease and Desist Orders issued by the Colorado Department of Health in April 1975. This paper addresses the task of developing a fluoride removal process. The task of developing a fluoride removal process was broken into two stages; (1) a literature search to determine and compare methods, and (2) a testing plan to quantify the parameters of the most promising method. The literature search revealed activated alumina adsorption to be the most efficient up to 10 ppm levels of fluoride (these levels are above those found on the north boundary at RMA). While the important parameters (pH, flow rates) were listed, the values were ranged rather than quantified. The effects of different types of activated alumina were not listed possibly due to the non-availability of these different types of activated alumina at the time. This testing plan seeks to find the optimal values of flow rates, pH and type of activated alumina plus the backwash efficiency. The testing plan was designed so that the optimal values for these parameters can be scaled-up to a full sized pilot plant used in series with the Calgon Activated Carbon Adsorption Plant. The objective of this study is to determine if the activated alumina adsorption method is a technically and economically feasible method of removing fluoride from the north boundary groundwater.
