Title National Radon Action Month in California - Testing for Radon from Well Water and Indoor Environments
Introduction LA Testing offers analytical services and test kits to identify radon risks in homes, schools and work environments.

Huntington Beach, CA, January 15th, 2019

The month of January is recognized as National Radon Action Month across the United States. While many California residents have no idea if they are living, working or going to school in a building that has elevated radon levels, this month of recognition is meant to spur them into action to find out the answer. This is important because as reported by the U.S. Environmental Protection Agency (EPA), “Radon is the leading cause of lung cancer deaths among nonsmokers in America and claims the lives of about 21,000 Americans each year.”

Radon is a radioactive gas that has been found in numerous buildings throughout California. It comes from the natural breakdown of uranium and thorium in soil, rock and water. The gas typically moves up through the ground to the air above and can get into a home or building through cracks and holes in the foundation.

It can also enter a property through private well water. The Centers for Disease Control and Prevention (CDC) states, “While most radon-related deaths are due to radon gas accumulated in houses from seepage through cracks in the foundation, 30 to 1,800 deaths per year are attributed to radon from household water. High levels of dissolved radon are found in the groundwater in some areas flowing through granite or granitic sand and gravel formations. If you live in an area with high radon in groundwater it can get into your private well. Showering, washing dishes and laundering can disturb the water and release radon gas into the air you breathe.”

According to the California Department of Public Health (CDPH) there are currently no Federal or State drinking water standards for radon in California. “The radon in your water supply poses an inhalation risk and a small ingestion risk,” reports CDPH for those with private well water and radon issues.

“For California residents concerned about exposure to radon, the good news is testing services are available that are inexpensive and provide the answers needed to protect families, students and employees,” said Michael Chapman, Laboratory Manager at LA Testing’s Huntington Beach facility. “At LA Testing we offer complete radon testing services and even provide easy to use test kits. If test results indicate elevated levels are present, there are radon reduction systems for the gas coming from below a building or from well water that can be installed to mitigate the problem.”

In support of National Radon Action Month, LA Testing recently sponsored an educational video about radon in private well water that can be seen at:
