Abstract:

The apparatus is a chamber within a ground excavation filled with porous material, with multiple angled well shafts projecting outward and down from the chamber. A pump located within the chamber pumps ground water from the several well shafts to a collector above ground, while a second pump in a sump adjacent to the chamber collects and removes contaminants which flow toward the sump because of the cone of depression formed by the several angled wells removing ground water. The angled well shafts located below the sealed chamber yield a much larger cone of depression than a single well, and use many fewer pumps than would multiple isolated vertical wells. Another advantage is that the system can operate without significant structures above ground, so that the apparatus is particularly well suited for decontaminating locations such as rail yards and other high traffic locations.
