Short description: The purpose of the demonstration was to evaluate a complete perchlorate ion exchange process for groundwater that included a unique, regenerable, perchlorate-selective ion exchange resin; an efficient regeneration technique that greatly minimized waste volume; methods for treating regeneration waste from this process that would reduce cost by enabling discharge or reuse; and to demonstrate a new perchlorate field monitor with ppb detection. In order to validate the performance and economics of the proposed processes compared to current perchlorate treatment processes, the following objectives were proposed: Demonstrate perchlorate removal in groundwater from >50 ppb to ¡Ü 5 ppb with a regenerable, perchlorate-selective ion exchange process. Demonstrate an efficient regeneration technique of the perchlorate-selective ion exchange resin. Regenerant volume should be < 0.1% of treated groundwater stream. Demonstrate removal or destruction of perchlorate (¡Ü 5 ppb) in the regenerant stream enabling discharge or reuse of the regenerant stream. Demonstrate the performance of a perchlorate field monitor capable of on-line, real-time perchlorate analysis with a minimum detection limit of 1 ppb
