Taylor County, TX radon potential

EPA places Taylor County in Zone 3 - Low Potential — a predicted county-wide average indoor radon level below 2 pCi/L, based on the geology, soil and aerial radioactivity data behind EPA's national map. Nationally that's the 28th percentile for radon potential — Taylor County outranks 28% of every county EPA has rated.

Where Taylor County sits nationally

Taylor County, Texas is home to about 148,813 people across 915.536 square miles. Population density there runs about 163 people per square mile.

Geologically, Taylor County is grouped into EPA Region 6 alongside 502 other counties that share its rock and soil setting.

Why the zone isn't the answer by itself

Taylor County's Zone 3 prediction undercuts the roughly 1.3 pCi/L most US homes average, nowhere near EPA's 4 pCi/L threshold for recommending mitigation. A Zone 3 label describes Taylor County's average, not any one basement or slab in it — testing is still the only way an individual homeowner actually finds out.

If Taylor County tests above the action level

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.
