Radon Levels in Curry County, New Mexico

EPA puts Curry County in Zone 2, its middle radon zone, and most reported tests there come back low, though 3.7% of 135 (2008 to 2017, laboratory totals) reached 4 pCi/L. Homes with elevated levels occur in all three zones, so only a test measures yours.

Predicted: EPA radon zone

EPA Zone 2: moderate predicted potential

Curry County is a county: EPA's forecast for it as a whole is an average indoor of 2 to 4 pCi/L (75 to 150 Bq/m³). It describes no single address, and homes above EPA's are found in every zone, this one included.

Curry County, Compared

Curry County radon figures, compared

Calculated by Radon411

Only 5 of 135 radon tests reported for Curry County over the 2008 to 2017 laboratory totals reached 4 pCi/L (3.7%). The median result, 0.6 pCi/L, sits below 2, well under EPA's 4 pCi/L action level, and the top reported result was 57.0 pCi/L.

Across 29 New Mexico counties pooled together, 28.5% of tests reached that level, so Curry County runs 24.8 points below its state. Against the national pool of 35.7%, the gap is 32.0 points lower. Its place in the state: 8th of 8 New Mexico counties with 30 or more tests for the same period.

The reported tests do not follow EPA's Zone 2 label for Curry County (predicted average between 2 and 4 pCi/L): 3.7% of them reached 4 pCi/L, fewer than that label suggests.

Below the action level, 125 tests (92.6%) came in under 2 pCi/L, against 41.3% statewide, and 5 tests (3.7%) fell between 2 and 4, against 30.2% statewide. USGS geology rates 100% of the county's land moderate radon potential.

CDC's ten-year totals for Curry County went from 14 tests (2005 to 2014) to 135 (2008 to 2017), the share going from 71.4% to 3.7%.

Curry County, Geology

The ground under Curry County

Predicted

USGS's geologic map puts all of Curry County's mapped land in one class: moderate radon potential. The map puts 92.4% of Curry County in the area it calls Ogallala Formation/High Plains and 7.6% in Great Plains Pecos Valley Section. USGS gives both a radon index of 9, in the moderate band (9 to 11).
