Why the zone isn't the answer by itself

Fleming County's Zone 2 prediction clears the 1.3 pCi/L national indoor average without reaching EPA's own 4 pCi/L point for recommending a fix. A county-wide moderate average, like Fleming County's, can still hide a specific house well above or below it — testing is what actually answers the question.

Testing and mitigation in Fleming County

Nothing about Fleming 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.
