    Maine Radon Mitigation

    Maine Air & Water Radon Mitigation Registration # ME02802P

    Radon is a naturally occurring radioactive gas being created by the breakdown of uranium in soil and rock beneath the earth’s surface. It is odorless and colorless and present at low levels even in the outside air we breathe. As radon-gas moves toward the surface it can enter through the cracks and openings within the foundations of homes and other structures and become trapped. Radon may also be contained in well water, and released into the air by everyday usage such as showering, laundry, etc., particularly if the source is a private well. Think of a well as an easy underground pathway for the gas to follow.

    As a radioactive gas, radon has been identified as a human health hazard by the (EPA) United States Environmental Protection Agency. Inhalation of radon gas leads to an increased risk of lung cancer, and in fact the Surgeon General has warned that radon is the second leading cause of cancer in the United States today. Only smoking causes more lung cancer deaths.

    As indicated, radon occurs naturally in the air both inside and outside your home. It is the concentration level present in your home that will determine if action should be taken to reduce the level to the EPA guidelines. Testing is the only way to accurately measure the radon level in the water and air. Radon testing is relatively inexpensive and can be done quickly.

    Radon is a fixable problem. Even very high levels in the water and air can be reduced to acceptable levels through a variety of methods.

    Although the technology does not exist to consistency reduce air radon levels inside a home to that of outside air, most homes can be reduced to 2 pCi/L or below. Radon exposure at any level is potentially harmful; therefore the goal of the professional mitigator is to achieve the lowest level possible using the best available technology.

    In most cases, systems using vent pipes and fans have proven to be the most effective in reducing air radon levels. These systems are called “sub slab” depressurization. These systems pull radon gas from beneath the concrete basement floor before it enters the home and exhaust it to the outside away from living areas. A mitigator will adapt the system to specific features of each home.

    Aeration systems are the most effective at removing water radon before it enters the home through the supply lines to various plumbing fixtures. This is called point-of entry treatment. This system involves mixing the water with air to cause release of the radon gas, which is then vented to the outside. These systems can work in conjunction with the removal of other contaminants in water, which should be explained by the mitigator. Your registered mitigator is responsible for the proper design and installation of your radon reduction system. This will include adherence to building codes and a complete explanation of the operation, maintenance and warranties that apply.
    A post-mitigation test will be conducted to insure the effectiveness of the system.
