Wayne County, NY: EPA's radon zone, explained

Wayne County is mapped as Zone 2 - Moderate Potential by EPA — meaning the county-wide average indoor level is predicted between 2 and 4 pCi/L. Wayne County sits at the 59th percentile nationally for radon potential — above 59 of every 100 rated counties.

Wayne County by the numbers

Wayne County, New York is home to about 90,757 people across 603.83 square miles. That works out to roughly 150 people per square mile. By population, Wayne County is the 221st largest of every county sharing its EPA zone — the 79th percentile by population within that zone. Geologically, Wayne County is grouped into EPA Region 2 alongside 82 other counties that share its rock and soil setting.

Why the zone isn't the answer by itself

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 Wayne County's Zone 2 prediction. Middle-of-the-pack doesn't mean risk-free for any one Wayne County address — a moderate county average still leaves individual homes to test either side of it.

If Wayne County tests above the action level

For a Wayne 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.
