Zone vs. an actual test

EPA's Zone 2 rating for Breckinridge County sits below its own 4 pCi/L action level but above the national indoor average of about 1.3 pCi/L. Middle-of-the-pack doesn't mean risk-free for any one Breckinridge County address — a moderate county average still leaves individual homes to test either side of it.

If Breckinridge County tests above the action level
