    Abstract: A radon stripper system for removing radon from well water including a draft tube and an air supply line that is interfaced with a gas supply. The draft tube is vertically aligned beneath the surface of the water in a well. Gas is delivered into the draft tube a sufficient distance induces a flow in the well water.
