METHOD FOR DIRECTING GROUNDWATER FLOW AND TREATING GROUNDWATER IN SITU

摘要

A method for treating groundwater in situ in rock or soil. An elongate permeable upgradient zone (2) and an elongate permeable downgradient zone, each in hydraulic communication with a permeable subsurface treatment zone (14) and having a major axis parallel to a non-zero component of the general flow direction (8), are provided in the subsurface by any of a number of construction methods. The upgradient zone, downgradient zone, and treatment zone are situated within the subsurface medium (4) and have permeabilities substantially greater than the adjacent subsurface medium's permeability.
