Is Haywood County, NC a radon risk area?

EPA's own radon map rates Haywood County zone 2 - moderate potential, predicting a county-wide average indoor level between 2 and 4 pCi/L. Rank it against the rest of the country and Haywood County lands in the 57th percentile for radon potential.

How Haywood County compares

About 63,048 people live in Haywood County, North Carolina, spread over 553.56 square miles. That works out to roughly 114 people per square mile. Rank 295 by population within its EPA zone puts Haywood County at the 71st percentile among zone peers. EPA's geology-based Region 4 groups Haywood County with 735 other counties nationally sharing its underlying rock and soil profile.

Why the zone isn't the answer by itself

Haywood County's predicted average falls between EPA's 4 pCi/L action level and the national indoor average of about 1.3 pCi/L (outdoor air runs roughly 0.4 pCi/L). Nothing about a Zone 2 label lowers the case for testing in Haywood County — EPA recommends it in every zone, moderate included.

If Haywood County tests above the action level

Nothing about Haywood 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.
