of Radon at Tahoe

In the interest of encouraging quality radon services at Tahoe and surrounding areas, Radon at Tahoe seeks to promote local radon service providers who meet local, state and national certification requirements, who have contractor's licenses in their state, and who have earned a reputation for quality work and fair prices. Local radon vendors wishing to become a Sponsor, please contact me with your radon qualifications: jeff@jeffminerconsulting.com

Caveat Emptor
While Radon at Tahoe feels these individuals are qualified radon specialists with certification and good work ethics, the customer is ultimately responsible for who they hire and for supervising the work that is performed. Radon At Tahoe offers this service to benefit all concerned, but can take no responsibility for the final outcome of the job or the business relationship between customer and vendor. And in radon, as in most contracting situations, a knowledgable customer is usually a good predictor of a satisfactory job. Customer comments are welcome and Caveat Emptor - "Let the buyer beware" - always applies.

That said, we are proud to have these radon service providers as sponsors.

The DPH radon web site is a good source of radon information and links. It is also a good source of certified radon testers and mitigaters in California.

California Certified Radon Mitigators and Testers

Ron Churchill
California Geological Survey, Hazard and Mineral Resource Mapping

Ron developed the Tahoe Area Radon Map which should help planners adopt radon building plans and hazard reports based on the high radon levels of this region. The map is based on data from the 2007 Tahoe Radon Survey. It is available on their web site above.

A Note on Radon Certification:

National organizations such as NEHA - NRPP and NRSB provide a program of study and testing to insure that candidates are sufficiently schooled in the current best methods of radon mitigation, and that they stay current by taking continuing education courses (and pay their dues!). Various states require that a contractor be certified by one of the national organizations to be listed that state's radon web site.

California is a Certification State. To be listed on the California Radon website and to be legal to perform "radon services" in California, one must be certified by one of those national organizations and must keep their license current. Always choose a California Certified radon mitigator for work to be done in California. There is a $1,000 fine to the radon contractor if he is not certified in California.

Nevada is a Non-Certification State. If you live in or near Nevada and are performing radon services in Nevada you may apply to be listed on the Nevada Radon Mitigators web site. It is always better to choose a certified individual in a Non-Certification State just because you know they at least took the classes and are practicing the EPA approved protocols for mitigating radon. In some states back East there is a problem of cheaply done and often ineffective or unsafe radon mitigation systems. Luckily at Tahoe we do not have that problem yet, but consumer awareness is the key to quality work. It's up to the buyer to demand the job be done right!

Dave Johnston, Supervising Hazardous Materials Specialist,
Email: davej@co.el-dorado.ca.us Phone: 530-621-5300

Dave has attended radon abatement training sessions in Washington D.C. and he questioned the presenters on the confusing inverse relationship between the level of radon in a county and the number of cases of lung cancer in that same county. He has no explanation on why counties with the highest radon levels have the lowest incidents of lung cancer, while the counties with the lowest radon levels have the highest incidence of lung cancer. I have not seen the statistics but taking him at his word, my guess might be that it could be partially explained by the long wait period to get cancer from radon gas, mixed with a possible high transiency rate in those counties. More research here would be helpful.

Shane was helpful in sending me information on government web sites, though no programs exist in his department to test for or abate radon in El Dorado County.

I could find no radon programs under environmental health or hazardous wastes for this county planning department, either at Lake Tahoe or in Placerville.

South Lake Tahoe - 530-573-3330
Larry Lohman, Branch Manager
Jim Swanson, County Building Inspector

Larry has no programs to test for or abate radon through building permits in the county portions of the Lake Tahoe Basin. He says if it's not in the Uniform Building Code it can't be enforced. He was not interested in applying for a free all expense paid training on radon mitigation in new construction because he would not be able to enforce the new methods.

Planning Department

Judy Finn - 530-542-6020

My research indicates that building departments and planning departments do not currently issue testing or mitigation guidelines or specifications to those building houses. When asked, they refer me to the environmental management agencies. I think this is a weakness in the building and planning process as home owners are not made aware of problems or even potential problems before they move in to a new home. Fixing it after the fact is usually more difficult (and expensive) than during the planning and building stage.

Dave Walker - 530-542-6010
Currently no plans to issue radon testing guidelines or requirements with building permits. Recent (2011) data shows a much more active role by the building department in handing out radon literature or at least to have is available in the lobby.

Funds may be available to reduce high radon levels in rental housing
There are some federal programs that might be used to help fund radon reduction in homes that are affordable to limited income families. These programs generally give money to local agencies or groups, which then fund the work. Some examples are:

Community Development Block Grant (CDBG) program - funds rehabilitation and repair of affordable housing. For more information, call the U.S. Department of Housing and Urban Development (HUD) at (202) 708-3587.

"203k" program - funds rehabilitation and repair of single family homes. For more information, call HUD at (202) 708-2121.

Environmental Justice Grants - funds community-based organizations and tribal governments addressing environmental concerns of people of color and low income communities. For more information, call EPA's Office of Environmental Justice at (800) 962-6215.

Professional Testing

Certified radon testers are available in South Lake Tahoe, Sacramento, Carson City and Reno who will come up to Tahoe to test a house. They use expensive and sophisticated monitors that detect fraudulent tampering with the test for real estate transactions, as well as canister tests sent off to a lab. You can view a list of certified testers in California at the National Environmental Health Association - http://www.cdph.ca.gov/healthinfo/environhealth/Pages/RadonServiceProviders.aspx

See the Sponsors box at the top of this page, but here is a partial list of other local testers I am aware of. There may be more. Please do your own research. I do not endorse any of these, but only list them for your information

Alan Bennet
Sierra Radon Services

Reno, NV - 775-853-1409
Alan uses canister testing sent out to certified radon labs. This is one of the few local radon mitigation services. Does not like to come up to the Lake, last time I checked.

A note on pricing:
As of 1/19/2007, the California Radon web site list only three certified radon mitigators, and they are all in Southern California. One came to Tahoe and charged nearly $4,000 to mitigate the house of one of my radon tester customers.

As of 10/25/2011 there are 11 mitigators on the California list and 6 close to Tahoe.
