U.S. Environmental Protection Agency Office of Solid Waste and Emergency Response Technology Innovation Office Permeable Reactive Barriers Interim Summary Report: Permeable Reactive Barriers Using Continuous Walls to Treat Chlorinated Solvents

The report provides an interim summary of six projects (five full-scale and one pilot-scale) using permeable reactive barriers (PRBs) with continuous subsurface walls composed of various reactive media to treat groundwater contaminated primarily with chlorinated solvents. A PRB contains or creates a reactive treatment zone oriented to intercept and remediate a contaminan
