| Abstract: | This paper presents the results of bench-scale tracer tests for evaluating the hydraulic performance of two permeable reactive barrier (PRB) media: granular iron and an iron/copper mixture. A PRB was installed at the former Naval Airstation Moffett Field, CA. The utility of a field tracer test used to evaluate ground-water flow direction and velocity through the permeable iron cell of the funnel-and-gate barrier is discussed. |

| Abstract: | A pilot-scale, funnel-and-gate system with a zero-valent iron permeable reactive barrier has been constructed at Moffett Airfield in Mountain View, CA to treat VOCs in ground water. The authors present a performance evaluation of the barrier, describing quarterly and continuous water level monitoring, down-hole ground water velocity measurements, slug tests, tracer tests, and ground-water flow modeling using MODFLOW. |

| Abstract: | The DOD's Environmental Security Technology Certification Program (ESTCP) has sponsored a demonstration project to validate the permeable reactive treatment wall technology for remediating chlorinated hydrocarbons in ground water and to develop performance monitoring criteria and cost-effectiveness data. A pilot-scale permeable reactive iron wall project was initiated at the former Naval Air Station (NAS) Moffett Field, CA site in April 1996, where a funnel-and-gate system was installed across a portion of a ground-water plume contaminated with such solvents as TCE, PCE, and DCE. |

| Abstract: | In 1996 at Moffett Airfield, CA, a funnel-and-gate permeable reactive barrier was constructed to treat ground water contaminated with dissolved chlorinated VOCs. The results of monitoring chemical and hydrologic conditions in and around the barrier and geochemical modeling have been used to assess its performance. Oxidation of iron, precipitation of carbonate minerals and ferrous sulfide, and promotion of anaerobic microbial growth are early signs of iron and ground-water interaction. |
