Predicted: EPA radon zone

33 of 33 counties classified

EPA classifies counties, not states. Of the 33 counties in New Mexico with a zone, 7 are in Zone 1 and 26 in Zone 2.

  • Zone 1: Highest predicted potentialgreater than 4 pCi/L7 of 33 counties · 21.2%
  • Zone 2: Moderate predicted potential2 to 4 pCi/L26 of 33 counties · 78.8%

An EPA radon zone describes predicted potential across a whole county. It is not intended to determine whether any individual home should be tested, and homes with elevated levels occur in all three zones. EPA recommends testing every home regardless of zone, and testing is the only way to know the radon level in a specific building.

How do I get a radon test in New Mexico?

Who does radon mitigation in New Mexico?

EPA recommends having a qualified contractor fix a home with a radon problem, because lowering high radon levels takes technical knowledge and special skills, and some states require the work to be done by a licensed or certified professional.

Which New Mexico counties are in EPA radon Zone 1?

7 counties are in Zone 1: Bernalillo County, Colfax County, Mora County, Rio Arriba County, San Miguel County, Santa Fe County, Taos County. Zone 1 is EPA's class for highest predicted potential, a predicted average indoor screening level greater than 4 pCi/L. A zone is a prediction for a county, not a measurement of any home.

Which New Mexico counties have the highest radon?

33 of New Mexico's 33 counties have an EPA radon zone published here. Radon411 will not rank counties on data it does not hold, and a zone is a prediction for an area rather than a measurement of any building.

What share of radon tests in New Mexico are high?

CDC has published no statewide radon testing statistics for New Mexico, so we cannot give a figure. Where CDC does publish one, the percentage describes radon tests reported to CDC, not homes.

Which EPA region is New Mexico in?

New Mexico is in EPA Region 6: South Central.

Do I need to test my home in New Mexico?

Yes, wherever you live in the state. Testing is the only way to know the radon level in a specific building. EPA recommends fixing a home when the radon level is 4 pCi/L or higher. EPA recommends considering a fix when the level is between 2 and 4 pCi/L.

Why does this page show coverage rather than one radon level for New Mexico?

A statewide figure averages counties with very different geology and very different numbers of reported tests, so it hides more than it shows. The county report is the level at which the EPA zone, the geologic potential and the reported testing statistics are actually published, which is why the county table above links to every one of them.
