What this actually means for a house in Jackson County

Jackson 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. Middle-of-the-pack doesn't mean risk-free for any one Jackson County address — a moderate county average still leaves individual homes to test either side of it.

Next steps for a home in Jackson County
