Description:
Permeable reactive barriers are innovative and cost-effective remedial technologies and are becoming more desirable methods for in-situ passive remediation of ground water contaminated with chlorinated hydrocarbons and redox-sensitive metals. As contaminated water passes through a permeable reactive barrier, contaminants are degraded or removed, allowing uncontaminated water to continue its natural course, In 1996, a 46-m long, 7.3 m deep. and 0.6 m wide subsurface permeable reactive barrier was installed at the U.S. Coast Guard Support Center, Elizabeth City, NC, to intercept and remediate chlorinated solvents and chromate present in the ground water, The barrier matrix is composed of 100% zerovalent iron in the form of iron filings. Preliminary results indicate that the permeable reactive barrier is very effective in remediating chromate- and TCE-contaminated ground water.
