What is radon?
Radon is a gas that has no color, odor, or gustation and comes from the natural radioactive breakdown of uranium in the ground. You tin be exposed to radon by two main sources:
- radon in the air in your home (frequently called "radon in indoor air") and
- radon in drinking h2o.
Radon can get into the air your exhale and into the h2o you drink. Radon is also institute in small amounts in outdoor air.
Near of the radon in indoor air comes from soil underneath the home. As uranium breaks downwards, radon gas forms and seeps into the house. Radon from soil can get into whatever blazon of building - homes, offices, and schools - and build up to high levels in the air within the building.
Radon gas can also dissolve and accrue in water from hole-and-corner sources (called ground water), such as wells. When water that contains radon is used in the home for showering, washing dishes, and cooking, radon gas escapes from the water and goes into the air. Information technology is like to carbonated soda drinks where carbon dioxide is dissolved in the soda and is released when you open the canteen. Some radon as well stays in the h2o.
Radon is not a business organisation in water that comes from lakes, rivers, and reservoirs (called surface h2o), considering the radon is released into the air earlier it always arrives at your tap.

Why is radon in drinking water a wellness concern?
Breathing radon in indoor air tin cause lung cancer. Radon gas decays into radioactive particles that can become trapped in your lungs when you lot exhale information technology. Equally they intermission downward further, these particles release small bursts of energy. This can damage lung tissue and increase your chances of developing lung cancer over the course of your lifetime. People who fume have an fifty-fifty greater risk. Non anybody exposed to high levels of radon will develop lung cancer. All the same, radon in indoor air is the second leading cause of lung cancer. About twenty,000 deaths a year in the U.S. are caused by breathing radon in indoor air.
But about 1-2 percent of radon in the air comes from drinking water. However animate radon increases the chance of lung cancer over the form of your lifetime. Some radon stays in the water; drinking h2o containing radon also presents a risk of developing internal organ cancers, primarily stomach cancer. Notwithstanding this risk is smaller than the risk of developing lung cancer from radon released to air from tap water.
Based on a National Academy of Science report, EPA estimates that radon in drinking h2o causes most 168 cancer deaths per year: 89% from lung cancer caused by breathing radon released to the indoor air from water and 11% from tum cancer caused past consuming water containing radon.

Is there radon in my water?
Non all drinking water contains radon. If your drinking water comes from a surface water source, such as a river, lake, or reservoir, near radon that might be in the water will be released into the air before reaching your water supplier or home. Radon is only a concern if your drinking water comes from hole-and-corner, such every bit a well that pumps h2o from an aquifer, though not all h2o from hush-hush sources contains radon.

What levels of radon in water should I be concerned nigh?
At that place is currently no federally-enforced drinking h2o standard for radon. EPA has proposed to regulate radon in drinking h2o from community water suppliers (water systems that serve 25 or more than yr-round residents). EPA does not regulate private wells.
EPA has proposed to crave community water suppliers to provide water with radon levels no college than iv,000 pCi/L, which contributes almost 0.iv pCi/L of radon to the air in your abode. This requirement assumes that the Country is as well taking action to reduce radon levels in indoor air by developing EPA-approved, enhanced Land radon in indoor air programs (chosen Multimedia Mitigation Programs). This is because well-nigh of the radon you breathe comes from soil nether the house. This option gives States the flexibility to focus on the greatest bug, past encouraging the public to gear up radon in indoor air problems and build homes that keep radon from entering.
Under the proposed regulation, States that choose not to develop enhanced indoor air programs, community water systems in that State will exist required to reduce radon levels in drinking water to 300 pCi/L. This corporeality of radon in h2o contributes about 0.03 pCi/L of radon to the air in your home. Even if a Country does not develop an enhanced indoor air plan, water systems may choose to develop their ain local indoor radon program and meet a radon standard for drinking water of four,000 pCi/50.
EPA proposed this option, under the framework specified by the 1996 Amendments to the Condom Drinking Water Act, and then that the overall risks from exposure to radon, both through air and water, are reduced.

How do I examination for radon in drinking water and how do I get rid of it?
- If yous get water from a public h2o system: Detect out whether your water arrangement gets its h2o from a surface (river, lake, or reservoir) or a ground water (underground) source.
- If the water comes from a surface water source, virtually radon that may exist in the water will be released to the air earlier it makes its way to your tap.
- If the water comes from a ground h2o source, telephone call your water system and ask if they've tested the water for radon.
- If you have a private well: EPA recommends testing your drinking water for radon. Call the Safe Drinking Water Hotline (one-800-426-4791) which can provide phone numbers for your State laboratory certification part. Your State laboratory certification function or State radon office can direct you to laboratories which may exist able to exam your drinking water for radon.
If testing your private well shows that you accept loftier levels of radon in your drinking water and y'all are concerned well-nigh it, there are some things you tin do to improve the h2o. The most constructive treatment you tin apply is to remove radon from the water correct before it enters your home. This is chosen point-of-entry treatment. There are two types of point- of-entry devices that remove radon from water:
- Granular activated carbon (GAC) filters (which use activated carbon to remove the radon), and
- Aeration devices (which bubble air through the water and behave radon gas out into the temper through an exhaust fan).
GAC filters tend to price less than aeration devices, yet, radioactivity collects on the filter, which may cause a handling take a chance and crave special disposal methods for the filter.
For more information on point of apply handling, you should contact the following independent certifying organizations: 
- NSF International;
- Water Quality Association; or the
- Underwriter'southward Laboratory.

I receive water from a public water supplier. How volition EPA'due south proposed regulation bear on me?
The proposed radon regulation does non affect public water systems or their customers. EPA must promulgate a final regulation before a federal radon regulation will exist enforced. Within iii years of promulgating the final regulation, your State may make up one's mind to develop a plan for an enhanced radon in indoor air programme, which would require your public h2o supplier to reduce radon levels in the water supply to 4,000 pCi/Fifty. Consumers may be interested in participating in their Country'due south evolution of this program, in one case the radon rule is finalized. If your land or public supplier does non develop an enhanced radon in indoor air program, your public h2o supplier volition be required to reduce radon levels to 300 pCi/L. Under either option, your water bills may increase depending on the size of your water supplier and the radon levels in the drinking water in your surface area.
