| Abstract: | In 1996, a 1,200-foot funnel-and-gate system was installed in the subsurface at the Denver Federal Center (DFC) to minimize the off-site migration of ground water contaminated with halogenated volatile organic compounds. The barrier consists of iron sheet-pilings driven across the aquifer perpendicular to the direction of ground-water flow, acting as an underground dam. Contaminated ground water is funneled through four 40-foot-wide gates in the barrier, containing iron filings. The iron filings are capable of chemically degrading dissolved chlorinated hydrocarbons such as TCE, DCE, and TCA in the ground water. The article includes a map of the DFC site and a schematic of the treatment barrier. |

| Abstract: | A model is applied to a field site at the Denver Federal Center, CO, where, in 1996, a zero-valent iron wall was installed as part of a funnel-and-gate system in a clastic aquifer to treat ground water containing TCA and other chlorinated aliphatic hydrocarbons. |
