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. After conducting 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 worldwide search that was performed to identify vendors of soil remediation equipment andor contractors who have successfully completed similar remediation projects. A number of information sources, including experts at government and RD institutions, libraries, professional journals, on-line services, academia and industry contacts were used to complete this report. Should the reader be interested in other environmental problems or other technologies not considered for this report, a listing of Internet sites searched during the effort is included and provides ample coverage of the remediation technologies available. The mention of trade names or commercial products in this report should not be constituted as endorsement or recommendation for use.
