1. A method for treating groundwater flowing in a general flow direction through a subsurface medium comprising:

  • providing an elongate permeable upgradient zone located hydraulically upgradient from and in hydraulic communication with a permeable subsurface treatment zone;

    providing an elongate permeable downgradient zone located hydraulically downgradient from and in hydraulic communication with the permeable subsurface treatment zone; and

    allowing groundwater to move from the subsurface medium surrounding the upgradient zone into and through the upgradient zone to, through, and out of the treatment zone and into, through, and out of the downgradient zone into the subsurface medium surrounding the downgradient zone; and

    treating the groundwater in the treatment zone, wherein each of the upgradient zone, downgradient zone, and treatment zone is situated within the subsurface medium and has a permeability substantially greater than the surrounding subsurface medium'"'"'s permeability.
