Radon is a gas which is a by-product of decaying radium that is transported through underground streams. When a faucet is turned on, the radioactive gas is released into the air and trapped in the home. This is what makes radon dangerous.
New Hampshire is known for having high levels radon in water, even in larger cities such as Manchester and Concord, NH where homes have both well and city water.
If a water test shows low levels of radon, a down-flow carbon filter can correct the problem. The filter media must be changed annually and a water test is recommended every two years. If levels increase, a more robust solution is required to remove the radon.
The best way to remove high levels of radon is with an air stripper, commonly known as a “bubble-up system.”
Bubble-up radon water systems have a storage tank of water and a small motor that aerates thousands of tiny bubbles from the bottom to the top. This frees the radon from the water and dissolves it into the air where it can be vented out of the building. This works much like a bottle of soda, where carbon dioxide fizzes and bubbles into the air from the liquid.
This method of water radon removal is the safest, most effective, and easiest to maintain. Absolute Water System is AARST-NRPP certified for radon measurement and mitigation specialists. We service all of New Hampshire, Massachusetts, and southern Maine.
