AWWA JAW23828

In 1986 and 1987, a survey was conducted of the occurrence of radon in well water within the American Water Works Company system. It was observed that the highest levels of radon occurred in the northeastern part of the United States and were associated with formations of uranium-bearing granitic rocks. The decrease in radon levels in water stored within the distribution system was attributable primarily to volatilization of the gas. Blending of radon-free surface water with radon-laden groundwater resulted in a water with a radon concentration that is a function of volumetric dilution. The use of granular activated carbon to reduce radon levels was found to be impractical, but aeration was observed to be cost-effective as well as efficient. Includes 9 references, tables.
