A system for removing contaminants from ground water, includes a plurality of tubular members made of a liquid pervious fabric material and having a rigid plastic core therein; a contaminant-absorbing material in each tubular member; an anchor cap secured to a lower end of each tubular member for preventing the contaminant-absorbing material from escaping from the lower end; a conduit positioned in each tubular member for supplying compressed air to each tubular member, the conduit having a lower, open end spaced above the lower end of each respective tubular member; and an air compressor for supplying the compressed air to each conduit.
