Covington city, VA: EPA's radon zone, explained

EPA places Covington city in Zone 1 - Highest Potential — a predicted county-wide average indoor radon level above 4 pCi/L, based on the geology, soil and aerial radioactivity data behind EPA's national map. Nationally, Covington city ranks higher in radon potential than 71% of rated counties (the 71st percentile).

How Covington city compares

Covington city, Virginia is home to about 5,663 people across 5.469 square miles. That works out to roughly 1,035 people per square mile. By population, Covington city is the 897th largest of every county sharing its EPA zone — the 16th percentile by population within that zone.

Zone vs. an actual test

Outdoor air nationally averages about 0.4 pCi/L, indoor air about 1.3 pCi/L — Covington city's Zone 1 prediction clears both of those and EPA's fix-it threshold besides. That doesn't mean every Covington city house tests high — a zone is a county-wide prediction, never a single-home reading — but it's a reason to test sooner rather than let it wait.

Next steps for a home in Covington city

For a Covington city 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.
