Charlottesville city, VA radon potential

Charlottesville city is mapped as Zone 2 - Moderate Potential by EPA — meaning the county-wide average indoor level is predicted between 2 and 4 pCi/L. Rank it against the rest of the country and Charlottesville city lands in the 54th percentile for radon potential.

How Charlottesville city compares

Charlottesville city, Virginia is home to about 44,767 people across 10.245 square miles. Population density there runs about 4,370 people per square mile. Within its own EPA zone, Charlottesville city is bigger by population than 64% of the counties that share it.

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

If Charlottesville city 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.
