What is the acceptable level of radon in drinking water?
300 to 10,000 pCi/L
Based on the potential for cancer, the EPA suggests that indoor air should not exceed 4 picocuries per liter (pCi/L). EPA and various states have recommended drinking water standards for radon in water ranging from 300 to 10,000 pCi/L but no standard currently exists.
Does Colorado Springs have radon?
Colorado Springs, like the whole county of El Paso, has average indoor radon levels of 4.9 to 9 pCi/L. This is almost double the 4.0 pCi/l “level for action” from the EPA in which they strongly recommend homeowners install Radon Mitigation Systems.
Does water softener remove radon?
The best method for removing radon from the water is an aeration system. An aeration system is typically installed next to the well tank where your water supply first enters the house. The aeration system is installed after other water conditioners such as a water softener or neutralizer.
Which of the following is most likely the source of the radon found in a house?
soil
The main source of indoor radon is radon gas infiltration from soil into buildings. Rock and soil produce radon gas. Building materials, the water supply, and natural gas can all be sources of radon in the home. Basements allow more opportunity for soil gas entry than slab-on-grade foundations.
Can a water filter remove radon?
Radon can be removed from water by one of two methods: GAC treatment – filtering water through granular activated carbon. Radon attaches to the carbon and leaves the water free of radon.
Where is radon most commonly found?
Radon levels are usually higher in basements, cellars and living spaces in contact with the ground. However, considerable radon concentration can also be found above the ground floor. Radon concentrations vary considerably between adjacent buildings, as well as within a building from day to day and from hour to hour.
Is radon testing required in Colorado?
Low cost radon test kits are available through the state and some counties. Radon is a naturally occurring radioactive gas that is the leading cause of lung cancer for nonsmokers and the second cause of cancer in smokers. …
How common is radon in homes in Colorado?
Nearly 73\% (that is every 3 out of 4 homes) of all homes in Colorado have high levels of the gas. The EPA recommended action level is 4 pCi (picocuries) of radon per one liter of air, meaning that any level higher than that requires mitigation. As said earlier, radon is naturally occurring.
How do you test for radon in water?
Call the Safe Drinking Water Hotline (1-800-426-4791) which can provide phone numbers for your State laboratory certification office. Your State laboratory certification office or State radon office can direct you to laboratories which may be able to test your drinking water for radon.
How do you get rid of radon in water?
Radon can be removed from water by one of two methods:
- Aeration treatment – spraying water or mixing it with air and then venting the air from the water before use, or.
- GAC treatment – filtering water through granular activated carbon. Radon attaches to the carbon and leaves the water free of radon.
Are radon tests accurate?
While any measurement system has an associated variability in precision and accuracy, we expect that radon test devices that are used properly will provide accurate and reliable results.
