IS URANIUM REGULATED?
The Safe Drinking Water Act covers uranium in public drinking water. The U.S. Environmental Protection Agency establishes maximum contaminant levels (MCLs) for radioactive contaminants in public drinking water supplies. MCLs are below levels at which health effects have been observed. Therefore, they are assumed to be protective of public health. The uranium MCL is 30 g/l (micrograms per liter) or 30 ppb (parts per billion) in drinking water.
Although private wells are not subject to the same regulatory standards as those set for public drinking water supplies, it is recommended for health purposes that private well owners use these standards to guide their water treatment decisions.
? COMMON QUESTIONS ?
Does uranium cause cancer?
There are insufficient data to determine if uranium causes cancer in humans and experimental animals.
Can I use my water for bathing and laundry?
Yes, this water can continue to be used for bathing, showering, dish and clothes washing. If there is uranium in your well water, test your home for radon gas, which is dangerous when inhaled.
Can I water my garden?
Yes, this water can continue to be used for growing food and will not contaminate the environment.
Is public water safe?
Yes. Public water providers work with state regulators to correct problems in systems that exceed the MCL. Corrective methods include obtaining a new water source, blending water from more than one source, and removing uranium by treatment.

WHAT IS URANIUM?
Uranium is a naturally occurring radioactive metal found in rocks, soils, and water. As a result, some private water wells in Georgia may exceed the federal regulatory standard for uranium in public water supplies. Uranium occurs more often in bedrock, and deep bedrock wells are more likely than shallow wells to have elevated levels of uranium. The amount of uranium in well water will vary greatly from place to place. Testing is the only way to determine if water contains uranium.
While exposure to elevated levels of uranium in drinking water for a short period of time is not an immediate health concern, uranium may pose a health risk when the water is used for drinking and cooking over many years. This is from the toxic effect of the uranium metal, not radiation. The amount of radiation emitted by uranium is very small, and poses little health risk.
You can be exposed to uranium by drinking and cooking with water containing uranium. Uranium does not absorb through the skin. It does not "evaporate" from the water into the air.
We can not eliminate exposure to uranium in the environment.
We can, however, reduce our health risks by minimizing exposure.
WHAT ARE THE HEALTH EFFECTS FROM URANIUM?
Natural uranium is in your normal diet, so there will always be some level of uranium in all parts of your body. Most uranium in drinking water is quickly eliminated from the body, but a small amount is absorbed from the digestive tract. Exposure to elevated levels of uranium over a long period of time can damage your kidneys. However, the kidney can recover from this damage after exposure is reduced or eliminated. It has not been determined whether uranium in drinking water causes cancer. Talk to your health care provider regarding your particular health concerns. Medical tests can measure for uranium in the body and for kidney function.
CAN I REMOVE URANIUM FROM MY WELL WATER?
The Georgia Department of Public Health recommends that you contact your county cooperative extension office or a state-certified laboratory and ask for a uranium test. The test costs about $50. If you do have elevated uranium, you can install a "point of use" filtration system in your home.
Point of use filtration systems can remove up to 90 percent of uranium in drinking water. These systems require proper installation and maintenance. A system costs about $500, plus the cost of installation. You can save money by installing a system yourself.
WHAT SHOULD I DO?
Sensitive Populations
Infants and young children are most at risk for adverse health effects from repeated exposure to uranium in drinking water. Because of their body weight and developing systems, infants and children are exposed to higher doses. Their growing bodies absorb more contamination and can sustain permanent damage if exposures occur during critical growth stages.
Therefore, pregnant and nursing women, women who may become pregnant, infants and small children are sensitive populations that should avoid consuming water with elevated levels of uranium for an extended period of time.
Test Your Home for Radon
When uranium is found in drinking water, the indoor air should be tested for radon gas. Radon
is a colorless, odorless gas that comes from the decay of uranium. Radon can build up in indoor air, resulting in an elevated radon level in the home. Radon emits particles that can be harmful to the human body, primarily the lungs. It is the leading cause of lung cancer among nonsmokers. In fact, everyone in Georgia should test their home for radon gas.
