Description

Pacific Northwest National Laboratory (PNNL), operated by Battelle Memorial Institute under contract to the U.S. Department of Energy, solicits interest from companies interested in obtaining license rights to commercialize, manufacture and market the following technology (hereinafter referred to as "technology"). License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. PNNL may also be available to licensee(s) to assist in further research and development of the technology under a sponsored research agreement or CRADA program. This invention is designed to intercept the flow of contaminated groundwater moving under a natural gradient. The intercepted groundwater passes through a permeable and reactive zone (the "barrier") that has been modified with a reactive agent. The reactive agent decreases contaminant concentration or toxicity by; (1) modifying the naturally existing geological material or introduced solid materials or (2) directly interacting with targeted contaminant. A variety of reactant liquids, gases or colloids, could be supplied to the reactive zone to treat a range of wide contaminants. The reactant would be introduced to the distribution lines under the influence of gravity or under pressure. The only energy input required to operate the technology would be the periodic re-supply of the reactant to the supply reservoir making this technology a "semi-passive barrier." The feeder lines could be placed either horizontally or vertically in the reactive zone. Horizontal lines could be placed in excavations, or threaded through the subsurface using directional drilling. Vertically placed feeder lines would be in the form of a well constructed to allow infiltration of the fluid. If the contaminated water was very near the surface the reactant could be supplied at or just below the land surface similar to "soaker hoses". Installation could also take the form of a geotextile (permeable fabric). The fabric would be constructed of hollow "threads" (fabric mesh of tubing) that would allow the diffusion or emission of the reactant to the subsurface. For full details, please see issued US Patent No. 5,803,174 and published PCT application WO 01/32325 A1 (application no. PCT/US00/29575).
