The present invention is a method and device for removing radon from groundwater without substantially reducing wellhead pressure. The pressurized radon stripper of the present invention has two principal components: a novel Venturi injector assembly which introduces air into a water process stream from a water source such as a well or the like; and a packed bed contactor which enhances air-liquid contact and serves as a gas-liquid separator. Over two thirds of the radon removal occurs in the Venturi injectors due to the intense gas-liquid turbulence in the throat of the Venturi valve.

[ We claim:] [1.] A method of removing radon from a water source comprising the steps of:passing radon-containing water of a predetermined pressure from the water source through a Venturi valve having a body with a predetermined cross-sectional area and a throat with a cross-sectional area less than the cross-sectional area of the body;introducing air into the water at the Venturi valve to separate at least a portion of the radon from the water;maintaining the water pressure of the water passing through the Venturi valve at no less than 75 percent of the predetermined pressure of the water source;passing the water from the Venturi valve through a packed bed gas/water separator having gas/water separation packing media therein;providing a gas outlet for exit of the radon and air separated from the water: andmaintaining the water pressure of the water passing through the packed bed gas/water separator at no less than about 75 percent of the predetermined pressure of the water source.
