Radon In New Hampshire's Well Water

If you get your water from an artesian well in New Hampshire, chances are there is some level of radon in your water. Radon comes from radium, a solid element commonly found in bedrock. As the radium breaks down it creates radon gas. The ground water flowing into your well picks up this radon gas and carries it into your water supply.

With all the granite in New Hampshire soil, the question is not  is there radon in the water, but is there enough radon in your well water to cause concern?

Radon is what you might call "aquaphobic." It would rather be in the air then in the water. When you turn on the faucet, the pressurized water that flows out from the faucet is now reduced to atmospheric pressure, and the gas is released into the air- similar to what happens to the "fizz" in a bottle of soda when it is opened for the first time.

Identify the source. If water can be a source for high radon levels in the air, it makes sense to identify whether the radon is coming from a soil gas entry source under the foundation, or if it is using the water as a conduit and "off-gassing" into the air when a faucet is turned on in the house. A New Hampshire radon removal specialist from Advanced Radon Mitigation has the experience to determine where the origin of the radon source is coming from, and then recommend the right system to mitigate it.

Your samples are submitted to an independent lab for an impartial determination on how high the radon levels are, and where they are the highest. If the upper living areas show higher radon levels than the basement, it's possible that a radon water treatment system will be required to bring radon levels down to a safe margin. If the test levels are found to be higher in the basement then chances are the source is a soil-gas entry problem under the basement floor. In that case, only a radon ventilation system will be needed.
