Radon Testing, Treatment and Mitigation for Your Canterbury, NH Home or Business May Be Necessary


Testing for radon in your Canterbury, NH home or business is becoming critical. As many as one in three Granite State homes are estimated to have elevated levels of this odorless, colorless, tasteless yet harmful gas. Exposure to this naturally occurring carcinogen, which results from the breakdown of radium, poses an increased risk of developing certain cancers, including those of the lung and stomach.

According the Surgeon General there is no safe or acceptable level of this gas, and radon is the leading cause of lung cancer nationally in non-smokers. State and federal agencies do recommend taking measures to lower the radon concentrations in the air of your home. They also recommend testing of your water if radon levels in the air of your home or business meet or exceed 4.0 picocuries per liter (pCi/L 4.0).

The professionals at Capital Well Clean Water Center will test the radon levels in your well and if needed, provide prompt treatment and removal.

The graphic below represents radon risk levels derived from test samples during a multi-year study of 24,000 wells across the state, and shows the percentage of homes within each town registering at or above the 4.0 pCi\L recommended, safe limit.

If the percentage of homes tested in your town are at or above the recommended limit, your radon action level is high. Additionally if you think any trace radon amounts are just not acceptable to you, then further measures, such as the testing of your well water, and/or the potential installation of a radon removal and mitigation system should be considered.

Again, there is no safe amount of radon, so even if your town is in a low percentage range, it is still wise to test your well and air quality to make absolutely sure radon isn't a potential health problem for your family. Any radon air quality reading in the home greater than 4.0 pCi/L and you should contact a professional to have your water tested!

  • George Craggy

    Jonathan, I wanted to drop a couple of lines to tell you how satisfied and happy that I chose Capital Well Co. for my water needs. From your lead man Steve to your drill people, your plumbing guy and your guy on the back hoe. Everyone that cast a shadow on my door threshold were polite, professional and willing to take the time to explain and answer my questions; which were many . Jon, it was my pleasure to meet you today and pleased that you came by for a follow up visit and explain how the heater works. SO...if I get a chance to tell everyone that needs a new well, I definitely will. It is apparent there is no "I" in your team . Thank you everyone.
  • Richard Meaney

    Mr. Swain, Thank you so much for the service Capital Well provided at my home today. I left a message with you at the behest of Ed Monty. I received a prompt phone call from Greg to arrange for a service call and to discuss what might need to be done. Promptly at (actually a few minutes before) the scheduled time, Bobby showed up to perform the service. Bobby was excellent at explaining the service, why some things were needed and how the well and pump worked, and answered all of my questions to my satisfaction. All in all, this was a very positive experience for us. Thanks to you and the people at Capital Well for prompt, courteous, and efficient service.
