Radon gas comes primarily from the ground and seeps into your home undetected. High levels of dissolved radon are found in the groundwater in some areas flowing through granite or granitic sand and gravel formations. If the water comes from a ground water source, call your water system and ask if they've tested the water for radon. In a small number of buildings, the building materials can give off radon, too. Radon is colourless, odorless, and tasteless. 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 a colorless, odorless, tasteless, and chemically inert radioactive gas. This is most commonly accomplished with an air diffuser mounted at the bottom of a storage tank filled with water to be treated. Just as uranium is present in all rocks and soils, so are radium and radon, due to radioactive decay. The U.S. EPA estimates that in homes served by wells, groundwater contributes about 5 percent of the radon found in the household air. You can inhale radon from the air and ingest it from the drinking water inside your home. What are the health effects of radon? Radon usually does not occur in significant concentrations in surface waters.Dissolved radon in groundwater will escape into indoor air during showering, laundering, and dishwashing. Radon is a naturally occurring radioactive gas created by the breakdown of uranium in the ground. Bill has helped people move in and out of many Metrowest towns for the last 34+ Years. “Old” water will have a lower radon concentration due to radon’s half-life of approximately 3.6 days. Health Canada has identified exposure to radon gas as the second leading cause of lung cancer after smoking, est… *Important: All dwellings need to be tested for radon; a wide spectrum of radon readings can occur in all three zones. Call the Safe Drinking Water Hotline (1-800-426-4791) which can provide phone numbers for your State laboratory certification office. Some public water systems treat their water to reduce radon levels before it is delivered to your home. Well water can also contain trapped radon, which may be released into the air when water is drawn. Extreme Levels of Radon-222 and Uranium in a Private Water Supply 22. Radon in soil under homes is the biggest source of radon in indoor air, and presents a greater risk of lung cancer than radon in drinking water. This technology has a higher front-end cost than granular activated carbon but has no associated disposal costs. If you suspect a problem and your drinking water comes from a private well, you may contact your state certification officerexternal icon for a list of laboratories in your area that will perform tests on drinking water for a fee. Radon in your home's water is not usually a problem when its source is surface water. Radon is a colorless, tasteless, odorless, radioactive gas. 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. If you have a private well: EPA recommends testing your drinking water for radon. We at Granite Inspection Group are a New York State Department of Health Radon Testing Laboratory and Licensed Mitigation and Remediation professionals. Disposing of the carbon may require special handling if it is used at a high radon level or if it has been used for a long time. You will be subject to the destination website's privacy policy when you follow the link. Granular activated carbon: This technology will remove 95 percent of the waterborne radon. Radon attaches to the carbon and leaves the water free of radon. Showers and sprays are a prime release method and the greater the water usage, the greater the potential radon problem. Any building may have a radon problem. Breathing in radon gas for extended periods of time can potentially be hazardous to you and … When the water is exposed to air the radon is released. We can do the test for your or you can pick up a radon test kit at your local UGA extension office. It occurs naturally and is produced by the breakdown of uranium in soil, rock, and water. Estimat… Zone 1 – High Zone 2 – Elevated Zone 3 – Guarded Relative Radon Hazard* Radon is a colorless, odorless gas produced by the radioactive decay of the element radium, which has itself been formed by the decay of uranium. The Environmental Protection Agency (EPA) estimates that radon causes some 21,000 lung cancer deaths a year in the U.S. alone. This means new and old buildings, well-sealed and draughty buildings, and buildings and homes with or without basements. When a radioactive gas, like radon, is inhaled, it naturally breaks down into radioactive particles that can … It can also dissolve into our water supply. How does radon enter a private well system? It is formed by the natural radioactive decay of uranium in rock, soil, and water. CDC twenty four seven. Types of Systems - GAC & Aeration. A greater level of success—as much as 99 percent removal—can be achieved when selecting a unit that utilizes a mister or nozzle located at the top of the tank to fill the tank along with a bubbler. Drinking water testing should be done by a certified drinking water testing laboratory. These wells could be private water wells or wells that are utilized by a public water supply system. Compared to radon entering the home through water, radon entering through the soil and house foundations represents a much larger risk. What type of treatment solutions are available? Radon Survey of the American Water Works System 20. When radon is released from the ground into the outdoor air, it is diluted and is not a concern. Physical hazards include noise, temperature, vibration and radiation. See Tables 1 & 2, pages 12 &13, of the EXP document wintersbay-water-tests7-exp , for the lake surface water analysis results, (page 12&13) Given that radon is a naturally produced substance in groundwater and not the result of human activities, there is no water well construction method that will prevent it from being in groundwater. It is a very wise idea to have the air of your home checked for high levels of radon gas. Studies show that inhaling radon can increase one’s chance of having lung cancer greater than stomach cancer.One can also likely increase his chance of getting lung cancer if he is exposed to radon plus he is a chain smoker. 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. However, in confined spaces, such as homes, radon can build up and become a health hazard. If you live in an area with high radon in groundwater it can get into your private well. The well water will only have a high radon concentration if it passes through a fracture with a high concentration of radium in the bedrock. 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. Health Canada recognizes radon as the next … In this map, the regions depicted reflect geologic conditions where higher radon readings might be found in Zone 1 versus Zone 2 and Zone 3 respectively. Subscribe to the monthly Private Well Owner Tip Sheet, radon entering through the soil and house foundations. The two most common treatment technologies are granular activated carbon and aeration: WellOwner.org is supported by the Rural Community Assistance Partnership (, Copyright © 2021 Wellowner.org - Water Well Resources and Water Well Service Directory.

We can do the test for your or you can pick up a radon test kit at your local UGA extension office. If inhaled, radon particles can damage lung tissue; Radon exposure increases the risk of developing lung cancer Radon (1) In addition to all other requirements, a building in the following designated areas shall be designed and constructed so that the annual average concentration of radon 222 does not exceed 200 Bq/m 3 of air and the annual average concentration of the short lived daughters of radon 222 does not exceed 0.02 working levels … In homes with a private well, radon entering from the water can raise the radon in air to very high levels and breathing this air for long periods can increase the risk of lung cancer. Some homeowners use a service contract from the installer to provide carbon replacement and general system maintenance. The U.S. EPA does not regulate residential wells, but private well owners may use the U.S. EPA’s proposed radon levels as their personal action levels. If you have public water and have a concern about radon, contact your water supplier. Radon is a radioactive gas that comes from the breakdown of uranium in soil and rock. Radon in well water can contribute to the indoor air levels of radon gas in your home by releasing radon into the air as water flows into sinks, tubs, and appliances.
