Hockley County, TX: EPA's radon zone, explained

Hockley 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. That puts Hockley County in the 47th percentile nationally for radon potential — higher than 47% of the counties EPA has rated.

Hockley County by the numbers

Hockley County, Texas is home to about 21,505 people across 908.392 square miles. That works out to roughly 24 people per square mile. By population, Hockley County is the 599th largest of every county sharing its EPA zone — the 42nd percentile by population within that zone. EPA's geology-based Region 6 groups Hockley County with 502 other counties nationally sharing its underlying rock and soil profile.

Why the zone isn't the answer by itself

Hockley 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 Hockley County's, can still hide a specific house well above or below it — testing is what actually answers the question.

If Hockley County tests above the action level

For a Hockley 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.
