The system removes contaminating gases, such as radon, from water using a bubbling action. Contaminated water is sprayed together with air through a duct to a bottom region of a bubbling container. The water and air move generally in the same direction through the system, allowing the flow rate to be varied while maintaining forced air/water contact. The aerated contaminated water bubbles upwardly through the bubbling container and passes through one or more diffusing or mixing plates causing the aerated contaminated water to further break out contaminating gases into the air. At the top region of the bubbling container, the contaminating gases are vented while the decontaminated water flows into a tank. The decontaminated water can then be pumped to a desired location, for example, to a house water system. A control system controls the operation of the system based upon water needs by stopping the introduction of air and water into the system when the decontaminated water in the tank has reached a predetermined level.
