What this actually means for a house in Baldwin County

Baldwin County's predicted average sits below the national indoor average of about 1.3 pCi/L, well under EPA's 4 pCi/L action level.

If Baldwin 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.
