Latest Patents

One of his latest patents is titled "Containment of Subsurface Contaminants." This invention describes a barrier designed to reduce the spread of a plume of subsurface contaminants. The apparatus includes a well system for injecting a fluid, such as air, just outside and below the periphery of the plume. The fluid is injected at a pressure sufficient to lower the hydraulic conductivity of the soil from the point of injection to the surface, thus establishing a curtain-like barrier to groundwater movement. This barrier is established upgradient of the plume to divert groundwater away, or preferably completely around the plume, to reduce the flow of groundwater into or out of the plume. The barrier enables the remediation of the confined contamination and dissipates quickly once the injection of the fluid is halted.

Another notable patent is the "In-situ Remediation System for Groundwater and Soils." This method and system focus on the in-situ remediation of contaminated groundwater and soil, where contaminants, such as toxic metals, are carried in a subsurface plume. The method involves selecting and injecting a fluid into the soil that will cause the contaminants to form stable, non-toxic compounds. This can be achieved either directly by combining with the contaminants or indirectly by creating favorable conditions in the soil. In cases of non-toxic metal contaminants, sulfides or sulfates are injected to form metal sulfides or sulfates. Alternatively, an inert gas may be injected to stimulate microorganisms in the soil to produce sulfides, which then react with the metal contaminants. The system typically employs two wells, one for injecting the fluid and another for extracting the unused portion, working in combination to enhance the mixing of the fluid and contaminants.
