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. High levels of radon in well water will off-gas radon into the air when showering, bathing, or washing clothes. Types of Systems - GAC & Aeration. You can inhale radon from the air and ingest it from the drinking water inside your home. Physical hazards include noise, temperature, vibration and radiation. Aquifers that have a more heterogeneous mixture of materials, such as sandstone or sand and gravel, typically do not have high radon concentrations or large fluctuation in radon concentrations. If you have a private well: EPA recommends testing your drinking water for radon. It is possible to have water tested for radon; however special collection vials are required. 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 … Radon is a colorless, tasteless, odorless, radioactive gas. What type of treatment solutions are available? Radon in water usually originates in water wells that are drilled into bedrock containing radon gas. When radon is released from the ground into the outdoor air, it is diluted and is not a concern. Some public water systems treat their water to reduce radon levels before it is delivered to your home. 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. 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. Call Nelson Water at 888.326.7082 for water treatment solutions to address hardness, taste/odor, pharmaceuticals and lead removal as well as sulfur, iron, sulfur bacteria, tannins, chlorine, chloramines, fluoride, toxic chemicals, uranium and radon in Ottawa, Kanata, Nepean, Gloucester, Stittsville, Chelsea, Alymer and Gatineau Ontario. Zone 1 – High Zone 2 – Elevated Zone 3 – Guarded Relative Radon Hazard* Radon is a naturally occurring radioactive gas created by the breakdown of uranium in the ground. 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. High levels of radon gas in the air of your home might be coming from your water and not the floor of your basement. What are the health effects of radon? Exposure can take place when taking a shower, doing laundry, or washing dishes. Nor do they know that radon is not part of a standard well water test. 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 means new and old buildings, well-sealed and draughty buildings, and buildings and homes with or without basements. 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. Showering, washing dishes, and laundering can disturb the water and release radon gas into the air you breathe. High levels of dissolved radon are found in the groundwater in some areas flowing through granite or granitic sand and gravel formations. Showers and sprays are a prime release method and the greater the water usage, the greater the potential radon problem. If you are on a private well, there are no regulations which require regular testing of the water, so you are responsible for ensuring the water is safe to drink. Sometimes radon enters the home through well water. Radon is colourless, odorless, and tasteless. If inhaled, radon particles can damage lung tissue; Radon exposure increases the risk of developing lung cancer 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. It can also dissolve into our water supply. Exposure to these hazards can be short- or long-term and can occur at home, school, work and in the community. Testing for it is the only way of telling how much is present. The Canadian Radon Guideline from Health Canada recommends the level of radon in the air of a home be no more than 200 Becquerels per cubic metre (Bq/m 3) per year. Radon is a radioactive gas that comes from the breakdown of uranium in soil and rock. We can do the test for your or you can pick up a radon test kit at your local UGA extension office. A radon-in-water test can be conducted to determine the extent of radon contamination in the well water. 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. Radon Survey of the American Water Works System 20. 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.

GAC treatment – filtering water through granular activated carbon. Testing Your Well Water Any building may have a radon problem. When the water is exposed to air the radon is released. Granular activated carbon: This technology will remove 95 percent of the waterborne radon. Radon is found across Canada because it occurs naturally in soil. And yes, radon can be deadly. Radon gas comes primarily from the ground and seeps into your home undetected. The Environmental Protection Agency (EPA) estimates that radon causes some 21,000 lung cancer deaths a year in the U.S. alone. 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. If the water comes from a ground water source, call your water system and ask if they've tested the water for radon. Think about why you’re considering a filter, Step 3. Water quality can vary greatly based upon natural fluctuations in the water source and the types of treatment techniques utilized by the water department. A radon in water problem is more likely when its source is ground water, e.g., a private well or a public water supply system that uses ground water. *Important: All dwellings need to be tested for radon; a wide spectrum of radon readings can occur in all three zones. 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. This technology has a higher front-end cost than granular activated carbon but has no associated disposal costs. We only install Aeration Systems. Health Canada recognizes radon as the next … If the radon-in-water levels are relatively low (less than 10,000 pCi/L in water), the water is likely not the source. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. Currently there is no federally enforced drinking water standard for radon. 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. 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. 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.
