If you are a homeowner the you are likely already familiar with radon gas and the different methods for radon mitigation. Radon gas is a harmful gas that is also impossible to detect without proper testing because it has no color and no odor. That is part of what makes radon gas so scary for homeowners. Unless they are proactive about testing for it then they will have no way to know if that harmful gas has been building itself up and seeping into a house through the cracks or gaps in the walls, pipes, construction joints and other small areas that only a gas could make its way through.
Many people think of radon gas as something that is sitting in the soil or rocks surrounding a normal home, but it is also a gas that can be present in the water supply. Homes that subsist off of a well for their water are at higher risks for radon contamination in their water, but radon can exist in low levels throughout any kind of water. We spoke with radon mitigation experts SWAT Environmental to find out more about the different ways that radon can be made and here is what we learned. Radon can exist in the soil as well as the water supply, but typically the radon levels in the rocks and soil will pose a much higher health risk than the radon levels in the water. This is a little surprising because when radon is in the water, you can be exposed to it through double whammy: you can ingest is as well as inhale it. Since radon is radioactive, the main health concern that exposure to it will cause an average person is cancer. When you inhale radon gas, you put yourself at a much higher risk of developing lung cancer.
When the main source of radon in your home is through the water supply, you also has a small risk of developing stomach cancer from the radioactive exposure, but the larger concern remains to be lung cancer. Radon that is in the water supply can become airborne when water is used inside the home for things like showering and cooking, and at that time the gas will be inhaled.
When you are deciding whether or not to have radon testing done on your home, you should take into account what kind of water source your house has. If it is a well or a public water supply system that gets its water from surrounding ground water, then you should definitely consider having the water source tested directly. If your numbers come back with elevated radon levels, then do not worry, it can be treated with a couple of different radon remediation methods. Point of entry treatment can treat and remove radon before the water actually makes its way into the home, and point of use treatment is used to remove radon from water as it comes out of your faucet. Each option has its own benefits and should be considered.
