Abstract: Concerning the presence of radioactive substances in groundwater used for public supply, particular attention is paid to radon removal in water treatment process. The processes based on water aeration are the most common methods for the reduction of radon concentrations in water. Simple spraying, bubble aeration in the deeper layers of water and various modifications of water aeration in a horizontal arrangement - Inka system and aeration towers - are used for radon removal from water. Vacuum de-aeration is another possibility of reducing the concentration of radon in water. However, this procedure is not widely used in practice as compared to the above methods. The article presents the results obtained from the pilot tests for radon removal by using the aeration tower and Inka aeration system in the water resource supplying the city of Istebné with drinking water.
