The U.S. Environmental Protection Agency plans to construct a 1,100-ft long sheet pile wall to anchor the remediation strategy for a contaminated 48-acre former industrial site along the Southern Branch of the Elizabeth River in Portsmouth, Va.
To be constructed approximately 250 ft offshore from what was for 66 years a major wood treatment facility operated by Georgia-based Atlantic Wood Industries, the wall will serve as a containment barrier for several thousand tons of creosote- and PCB-contaminated sediment that will be dredged from the river.
