The U.S. Army Environmental Center in partnership with the Naval Facilities Engineering Services Center and the U.S. Army Engineer Waterways Experiment Station demonstrated Physical SeparationLeaching methods for the remediation of small arms range soils. The demonstration occurred at Fort Polk, Louisiana. The primary objective was to demonstrate and evaluate the technical capability and document the cost effectiveness of the physical separationleaching family of technologies. The secondary objective was to identify technology sources, provide implementation guidance and transfer the technology to the user. After conduction a world-wide search, two vendors were selected to demonstrate two variations of the physical separationleaching technologies. The first using a process based on acetic weak acid chemistry and the second based on hydrochloric strong acid chemistry. Following completion of the bench treatability studies, each vendor performed a full scale 5-10 tons per hour, 1000 tons total demonstration of their respective technologies. This report documents the demonstration to include site planning, lessons learned and recommendations for additional developmental work.
