radon, lead and fluoride

About Radon: Radon is a radioactive gas that you can't see, taste, or smell. It is found throughout the U.S. Radon can move up through the ground and into a home through cracks and holes in the foundation. Radon can build up to high levels in all types of homes. Radon can also get into indoor air when released from tap water through showering, washing dishes, and other household activities. In most cases, the amount of radon entering a home from tap water will be much less than the amount of radon entering the home through soil. Radon is a known human carcinogen. Breathing air containing radon can lead to lung cancer. Drinking water containing radon may also cause increased risk of stomach cancer. If you are concerned about radon in your home, test the air in your home. Testing is inexpensive and easy. Fix your home if the level of radon in your air is four picocuries per liter of air (pCi/L) or higher. There are simple ways to fix a radon problem that aren't too costly. For additional information, call the California Air Resources Board (800) 272-4572 or call the EPA's Radon Hotline (800) SOS-RADON.
About Lead: Infants and young children are typically more vulnerable to lead in drinking water than the general population. It is possible that lead levels at your home may be higher than at other homes in the community as a result of materials used in your home's plumbing. If you are concerned about elevated lead levels in your home's water, you may wish to have your water tested and/or flush your tap for 30 seconds to two minutes before using tap water. Additional information is available from the EPA Safe Drinking Water Hotline (800) 426-4791.
Fluoride is found naturally in water delivered to Sweetwater Authority customers in levels below the amount recommended for preventing tooth decay. Customers concerned about fluoride use are urged to contact a doctor or dentist to discuss fluoride supplements.
