Radon tests reported for Eddy County, 2008 to 2017, laboratory
CDC holds 18 reported tests for Eddy County over the 2008 to 2017 laboratory totals, with a median of 0.5 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Eddy County beside the counties around it is how this page reads it.
What these figures count
Only 18 tests were reported to CDC for Eddy County over 2008 to 2017 (laboratory totals), and tests are often run on homes being sold or already suspected of a problem: so few describe neither the county nor this house.
Measured: CDC tracking data. Figure above: 2008 to 2017, laboratory. Measured data period: 2005 to 2017 (every CDC figure on file).
Eddy County, Compared
Eddy County radon figures, compared
Calculated by Radon411CDC's largest figure for Eddy County rests on 23 tests over the 2005 to 2014 laboratory totals, 1 of them at or above 4 pCi/L, so each test moves its share by 4.3 points and no rank or comparison is drawn from it. Results reached as high as 4.0 pCi/L, with a middle value of 0.9 pCi/L.
Of the counties bordering it, 2 have a figure over the 2006 to 2015 laboratory totals: Lea County reported the largest share at or above 4 pCi/L, 11.1%, and Otero County the smallest, 10.7%. Farther out, Lincoln County (110 miles away) at 20.6%, Doña Ana County (148 miles away) at 16.3% and San Miguel County (209 miles away) at 44.4% have figures too. Pooled across 30 New Mexico counties, 30.3% of reported tests reached that level; across every county in the country with a figure, 36.3%.
Statewide for the same period, Taos County reported the highest share (71.9%) and Otero County the lowest (10.7%). EPA's 1993 map puts Eddy County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 93% of the county's land moderate radon potential.
Pooled shares: Radon411's sum of CDC's county counts for one period.

The ground under Eddy County
PredictedMost of the ground under Eddy County is one class on USGS's geologic map: 92.9% of its land is moderate radon potential, with 7.1% low. The map puts 67.2% of Eddy County in the area it calls Basin and Range Sacramento Section and 25.2% in Great Plains Pecos Valley Section, with one smaller area beside them. USGS gives the first a radon index of 10 and the second 9, both in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Basin and Range Sacramento Section | Paleozoic marine limestones and shales. | Moderate | 10 | 67.2% |
| Great Plains Pecos Valley Section | Triassic sandstone, siltstone, mudstone, Quaternary alluvial and eolian sand and silt. | Moderate | 9 | 25.2% |
| Southern High Plains and Plateaus | Paleozoic and Mesozoic sandstone, limestone, shale. | Low | 7 | 7.1% |

Eddy County beside the ground around it
Across New Mexico 19.2% of the land is rated high; none of Eddy County's is. Of the 6 counties that border it, 1 has more high-potential ground, Otero County the most at 39.5%.

Eddy County, Cities and towns
Cities and towns in Eddy County
Eddy County's population has barely moved since 2020: 62,509 residents on July 1, 2025 against 62,344 then, by the Census Bureau's estimates. That works out to 15 people per square mile of land. Carlsbad alone is home to 32,524 of them, 52.0% of the total. Together its 4 incorporated places hold 74.8% of those residents; the other 25.2% live outside any of them. Reported testing is thin here: 23 tests over 2005 to 2014, or 0.4 for every 1,000 residents (2025 estimate), where New Mexico as a whole comes to 2.2.
From Carlsbad to Hope, CDC publishes no figure by town: each reads Eddy County's.
