Permeable Reactive Barriers (PRBs) Interim Summary Report: PRBs Using a Funnel and Gate Configuration
Site Name: | Multiple (14) Sites |
|
Location: | - Aircraft Maintenance Facility, Southern Oregon |
|
Period of | Installation dates ranging from 1995 (Intersil and East Garrington) - 2000 (Alameda Point) |

Cleanup | Full scale and field demonstrations The funnel and gate PRB configuration involves the use of engineered subsurface barriers to capture and route groundwater flow through one or more gates, where treatment occurs. In most cases, funnels have been comprised of sheet piling or slurry cutoff walls. However, engineered preferential groundwater flow pathways employing channels (sometimes referred to as "trench and gate" systems) also have been used to route groundwater flow to a reactive gate. |
