This report on the performance of permeable reactive barriers (PRB) for groundwater remediation was prepared under the auspices of the Federal Remediation Technologies Roundtable, a collaborative effort among federal agencies involved in hazardous waste site cleanup. Three United States (U.S.) government agencies, the Department of Defense (DoD), Department of Energy (DOE), and United States Environmental Protection Agency (EPA), as well as the Interstate Technologies and Regulatory Council (ITRC) contributed to the report, which is a concise summary of the conclusions and recommendations of the three agencies' individual studies at different sites.
