As required by the Safe Drinking Water Act, EPA has developed a proposed regulation to reduce radon in drinking water that has a multimedia mitigation option to reduce radon in indoor air. Radon is a colorless, odorless, tasteless, and chemically inert radioactive gas. In a small number of buildings, the building materials can give off radon, too. Point-of-use devices such as those installed on a tap or under the sink will only treat a small portion of your water and are not effective in reducing radon in your water. Call the Safe Drinking Water Hotline (1-800-426-4791) which can provide phone numbers for your State laboratory certification office. Although the U.S. EPA still considers the risk from ingestion to be small compared to the risk from breathing indoor air containing radon, it now says drinking water contaminated with radon may add some minor risk of developing stomach or other internal organ cancer. Although the granular activated carbon system has few moving parts and should have a long, useful life, radon build up over long periods of time becomes a low-level radioactive source requiring special disposal. Compared to radon entering the home through water, radon entering through the soil and house foundations represents a much larger risk. Some public water systems treat their water to reduce radon levels before it is delivered to your home. This means new and old buildings, well-sealed and draughty buildings, and buildings and homes with or without basements. Because the primary source of radon exposure is from breathing contaminated air in the home, removal should be where water enters a house or building. Water quality can vary greatly based upon natural fluctuations in the water source and the types of treatment techniques utilized by the water department. Point-of-use devices, such as those installed on a tap or under the sink, treat only a small portion of the water in the home and are not as effective in reducing radon; radioactivity also can build up on the filters of these devices and become a hazard. Radon from soil gas is the main cause of radon problems. Saving Lives, Protecting People, Centers for Disease Control and Prevention, National Center for Emerging and Zoonotic Infectious Diseases (NCEZID), Division of Foodborne, Waterborne, and Environmental Diseases (DFWED), Choosing Home Water Filters & Other Water Treatment Systems, Step 2. Regardless, it seems like a good idea that anyone with a deep drilled well, who lives on the lake year round, should consider having their water tested for uranium and radon. In the open air, radon poses limited health risks, as radon escaping from the soil is diluted in the open air. While most radon-related deaths are due to radon gas accumulated in houses from seepage through cracks in the foundation, 30 to 1,800 deaths per year are attributed to radon from household water. Testing for it is the only way of telling how much is present. It is possible to have water tested for radon; however special collection vials are required. It can be found in all 50 states. It can also be present in well water, where it can be released every time you turn on a tap or run the shower. Radon is colourless, odorless, and tasteless. What are the health implications? Linking to a non-federal website does not constitute an endorsement by CDC or any of its employees of the sponsors or the information and products presented on the website. High levels of radon gas in the air of your home might be coming from your water and not the floor of your basement. Estimat… When the water is exposed to air the radon is released. Sometimes radon enters the home through well water. We can do the test for your or you can pick up a radon test kit at your local UGA extension office. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Radon levels in well water can be significant depending on the source, but very high levels would be required to impact indoor radon levels by an appreciable amount. If you have public water and have a concern about radon, contact your water supplier. If inhaled, radon particles can damage lung tissue; Radon exposure increases the risk of developing lung cancer What type of treatment solutions are available? You can inhale radon from the air and ingest it from the drinking water inside your home. There are primarily two types of well water systems, Granular Activated Carbon (GAC) and Aeration Systems. However, in confined spaces, such as homes, radon can build up and become a health hazard. Bill has helped people move in and out of many Metrowest towns for the last 34+ Years. Radon in water usually originates in water wells that are drilled into bedrock containing radon gas. Exposure to these hazards can be short- or long-term and can occur at home, school, work and in the community. This technology has a lower front-end cost, but there are costs associated with disposal of radioactivity build up after many years. Consider how the filter fits your home, lifestyle, and budget, A Guide to Drinking Water Treatment Technologies for Household Use, Drinking Water Treatment and Sanitation for Backcountry & Travel Use, Information for Public Health & Medical Professionals, Water, Sanitation, & Environmentally-related Hygiene, U.S. Department of Health & Human Services, Aeration treatment – spraying water or mixing it with air and then venting the air from the water before use, or. How does radon enter a private well system? If testing reveals that you have elevated levels of radon in your water, we can help and have the experience, expertise and professionalism to address all your water containments and concerns. A water well system professional can determine whether your well can be retrofitted to draw from zones in which the water contains radon at levels consistently below the proposed U.S. EPA standard. Radon can be removed from water by using one of two methods: In either treatment, it is important to treat the water where it enters your home (point-of-entry device) so that all the water will be treated. While most radon-related deaths are due to radon gas accumulated in houses from seepage through cracks in the foundation, 30 to 1,800 deaths per year are attributed to radon from household water. Types of Systems - GAC & Aeration. If you are an owner or operator of a large drinking water system under Ontario regulation 170/03 and need more information, contact the Ministry of Environment, Conservation and Parks. There the radon continues to decay and give off radiation; however, the treatment equipment is usually not located in the living area of the home.
