Impact/Purpose: information Description: A 46 m long, 7.3 m deep, and 0.6 m wide permeable subsurface reactive wall was installed at the U.S. Coast Guard (USCG) Support Center, near Elizabeth City, North Carolina, in June 1996. WebThe PRB uses two reactive media: 69 tons of granular iron (Fe°) mixed with gravel at a 1:2 volume ratio (34.5 tons each of Fe° and gravel) in 33 ft of the wall and 85 tons of iron sponge in 41 ft of the wall. A concrete-filled borehole separates the two segments.
