Is radon high in Fayetteville, North Carolina?

Low. Averaging the model's ZIP-code predictions across Fayetteville (weighted by how much of the city each ZIP covers) gives a long-term basement mean of 1.3 pCi/L - about 28% below the US average of 1.8 and about 21% below the North Carolina average of 1.7. That is below the EPA's 2 pCi/L "consider fixing" threshold, though individual homes still vary. Fayetteville ranks 17 of 26 North Carolina cities on this site.

Which Fayetteville ZIP codes have the highest radon?

Predictions for the 10 modeled ZIP codes in Fayetteville range from 1.2 to 1.4 pCi/L in the basement. 0% of them are predicted at or above 4 pCi/L and 0% at or above 2. The city is fairly uniform, so the city-wide number is a reasonable guide for any neighborhood.

Should I test for radon in Fayetteville?

Yes, once. The EPA recommends testing every home regardless of area. A short-term kit costs little and settles the question for your house; Fayetteville's low predicted average describes the typical home, not yours.

What does EPA Radon Zone 3 mean for Fayetteville?

Fayetteville sits mainly in Cumberland County, which the EPA classifies as Zone 3 - low potential (< 2 pCi/L). The zone map dates from 1993 and covers whole counties. The 2001-2021 model agrees with the zone for the city. Neither replaces a test of your own home.

LowEPA Zone 3

Predicted long-term basement average of 1.3 pCi/L (model estimate) across the 10 modeled ZIP codes in Fayetteville - about 28% below the US average of 1.8, about 21% below the North Carolina average of 1.7. Ranked #17 of 26 North Carolina cities on this site. Most of the city lies in Cumberland County (its ZIPs also reach into 1 other county).

Test Fayetteville, NC once anyway - radon varies house to house

The predicted basement average here is 1.3 pCi/L, below the EPA's 2 pCi/L "consider fixing" threshold. That's good news for the area - but the EPA still recommends every home be tested, because foundation cracks, soil pockets and ventilation make one house very different from its neighbor. One inexpensive kit settles it.

Predicted (model estimate). The pCi/L figures on this page are long-term area averages from a peer-reviewed national model built on millions of real radon tests (2001-2021). They describe the typical home in this area - not your home, which can be several times higher or lower. The EPA radon zone is a separate, 1993 county-level classification. How the numbers work.

What this means for Fayetteville

The typical Fayetteville home is predicted below 2 pCi/L, the lowest band. That describes the average house; the ZIP-level predictions inside the city still span 1.2 to 1.4 pCi/L.

The city figure is not a separate estimate: it is the mean of the model's ZIP-code predictions, weighted by the share of the city's land in each ZIP (Census 2020 ZCTA-to-place relationship file). The 1993 EPA zone (3) for Cumberland and the 2001-2021 model agree here.

Comparable North Carolina cities: Holly Springs (1.3), Durham (1.3), High Point (1.3), Greenville (1.3).

Testing help in North Carolina

We link only state program pages we could verify, and North Carolina's did not respond when we checked, so start from the EPA state radon contacts page. If a test comes back at 4 pCi/L or higher, mitigation typically costs $800-$2,500 installed; use EPA find-a-professional and read the mitigation guide.
