Genesee County, NY radon potential

Genesee County is mapped as Zone 1 - Highest Potential by EPA — meaning the county-wide average indoor level is predicted above 4 pCi/L. Nationally, Genesee County ranks higher in radon potential than 91% of rated counties (the 91st percentile).

How Genesee County compares

Genesee County, New York is home to about 57,604 people across 492.976 square miles. Population density there runs about 117 people per square mile. Within its own EPA zone, Genesee County is bigger by population than 73% of the counties that share it. Geologically, Genesee 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

Genesee County's predicted average sits above EPA's own action level of 4 pCi/L — the concentration at which EPA recommends fixing a home — versus a national average around 1.3 pCi/L indoors and 0.4 pCi/L outdoors. A Zone 1 rating means testing is worth doing sooner rather than later, but it is still county-wide average, not a reading for any single house — some homes in Genesee County will test well under the action level, and EPA's guidance is to test regardless of zone.

Next steps for a home in Genesee County

A short-term test kit is the standard first step and typically costs far less than mitigation itself. If a test comes back at or above 4 pCi/L, a radon mitigation system for a typical home runs roughly $800–$2,500 (around $1,200 for a common single-family install), driven mainly by foundation type, not by county.
