Radon Levels in Your NH Drinking Water Pose a Health Risk

How to Detect Radon in Your New Hampshire Home or Business Well Water? Test, Test, & Test!!!

In New Hampshire, calling Capital Well Clean Water Center for radon testing and treatment is the first, best step toward understanding your specific radon levels, and in dealing with its eventual removal and mitigation. The water professionals at our Clean Water Center have the safe water systems and the experience to perform the tasks needed to keep your family and employees safe.

If you have elevated radon levels in the water or air of your NH home or business, it poses huge health problems. What you need to know to protect yourself and others.

Radon is a naturally occurring, radioactive, colorless and tasteless gas commonly found in the granite bedrocks of NH and in the public and private wells drilled from that bedrock. Nearly one out of every 15 homes in the United States is estimated to have an elevated radon level (4.0 pCi/L or greater), and in New Hampshire that number is one in three. Please pick your town from the drop down below to assess the risk of radon in your town, and in your home or business.

More on Radon in Your Home or Businesses Water and Air

Occurring as the product of the breakdown of radium, radon is considered a health hazard due to its high radioactivity. It typically enters the air of the home through cracks in the foundation and through the up flow of private well water and into your water systems. Any home, new or old, with or without basements, can face potential radon issues. Few homes are immune.

Radon from bedrock wells is not only ingested in the form of tainted drinking water but is also released into the air of your home during activities such as showering, dishwashing or doing laundry. Radon solids that leech into the air cling to dust particles and can attach to the airways of the lungs.

Exposure to radon poses an increased risk of developing certain types of cancer, primarily those of the lungs and stomach. Radon is the leading cause of lung cancer for non-smokers, responsible for 21,000 deaths annually.

When does the water in your well and home need to be tested?

State and federal agencies recommend taking mitigating steps when radon concentrations in the water or air meet or exceed 4.0 picocuries per liter (pCi/L) in the lowest and most commonly used spaces in your home or business.

Testing and Aeration | "There is NO safe level of radon..."

Radon concentrations in both air and water are measured in picocuries per liter (pCi/L). For every 10,000 pCi/L of radon in a home’s water supply, the radon concentration in indoor air is increased by 1 pCi/L, though according to the U.S. Surgeon General there is no safe level of radon, and testing is the only way to be sure you and your family are safe.

The primary method for radon removal from water is aeration, a process by which oxygen is driven or bubbled into the water, separating the radon gas from the well water. Although there are carbon options available, there are factors that make this method less attractive as a long term viable solution to your radon problem. Call Capital Well Clean Water Center today and ask us why aeration treatment is far superior, and why using a charcoal system needs to be carefully considered before choosing.

Radon concentrations in well water can vary substantially from one test to another, and the New Hampshire Department of Environmental Services recommends at least two radon tests, at least one month apart when possible, prior to making any treatment decisions.

    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.
