ABSTRACT:
For providing an in-ground system for treating contaminated groundwater, of the funnel-and-gate type, a cylindrical caisson is driven into the ground. The native soil is augered out of the caisson, and porous treatment material substituted. The caisson is then withdrawn, leaving a prism of porous treatment material in the ground. A sheet metal barrier element is inserted into the ground, one portion of the element extending into the prism and the other portion into the surrounding soil. More prisms are provided as further treatment gates, and more barrier elements are arranged to funnel the groundwater through the gates.
