Abstract
A system for intercepting, treating and venting vapors from contaminated soil in the vadose zone and from contaminated groundwater includes a large borehole and at least one small borehole each having an open top end, a porous liner against the outer wall and porous fill material inside the liner. The fill material can include materials to retard and degrade contaminants in the vapors. The large and small boreholes can have impermeable sections in the liner, and impermeable ground cover around the top ends. The large borehole can also include a slotted aeration tube in the borehole and vegetation planted in the open end of the borehole. A method for intercepting, treating and venting of vapors from contaminated soil in the vadose zone and contaminated groundwater includes the system and pulling vapors out the top end of the large borehole with variations in atmospheric barometric pressure.
