What this actually means for a house in Meigs County

Neither at the 4 pCi/L action level nor down at the roughly 1.3 pCi/L national indoor norm, Meigs County's Zone 2 prediction lands in the gap between the two. A Zone 2 rating is a moderate county-wide average, not a guarantee about any one house in Meigs County — testing is the only way to know an individual home's actual level.

If Meigs County tests above the action level

Nothing about Meigs 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.
