Is Jones County, NC a radon risk area?

EPA places Jones County in Zone 3 - Low Potential — a predicted county-wide average indoor radon level below 2 pCi/L, based on the geology, soil and aerial radioactivity data behind EPA's national map. That puts Jones County in the 6th percentile nationally for radon potential — higher than 6% of the counties EPA has rated.

Zone vs. an actual test

Well clear of both the 1.3 pCi/L national indoor average and EPA's 4 pCi/L action level, Jones County's Zone 3 prediction is the low end of the scale. Low doesn't mean zero: EPA's own data shows homes in Zone 3 counties like Jones County testing above the action level often enough that skipping a test isn't the safe assumption.

Testing and mitigation in Jones County

Nothing about Jones County's EPA zone changes the mitigation number: $800–$2,500 nationally (around $1,200 typical), set by the house's foundation rather than the county it sits in — and only relevant once a test actually clears 4 pCi/L.
