As water moves through the ground, radon gas can be carried in the water to your tap. When well water is agitated at warm temperatures in the home, radon is released into the air. When you shower, bathe or simply run the tap, the radon in the water is liberated into the air, forming radon gas that can be inhaled in. According to the EPA, radon levels in ground water are highest in New England and the Appalachian uplands of the Mid-Atlantic and Southern States. Certain areas around the Rocky Mountains, California, Texas and the upper Midwest also have elevated levels of radon in the ground water. These areas are most likely to have elevated radon in water levels, but radon in water can occur anywhere in the US.
Fixing the problem...
Simple aeration removes up to 99% of radon from water. Radon is rarely a problem in public systems because the water is aerated during water treatment. Unfortunately, this does not occur in water being drawn from a private well. Aeration treatment equipment aerates the water, then vents the gas to the outside. This treatment option requires that the gas be vented above the roof line, otherwise the gas may enter the home.
