Zone vs. an actual test

Call it a middle case: above the 1.3 pCi/L most US homes average, below the 4 pCi/L line EPA uses to recommend mitigation — that's Bartow County's Zone 2 prediction. A Zone 2 rating is a moderate county-wide average, not a guarantee about any one house in Bartow County — testing is the only way to know an individual home's actual level.

If Bartow County tests above the action level

For a Bartow County homeowner, the order is simple: test first, since a kit costs a small fraction of what mitigation would. Only if the result clears 4 pCi/L does a system — typically $800–$2,500, about $1,200 for a common install — become worth pricing out.
