Zone vs. an actual test

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 Lake of the Woods County's Zone 2 prediction. A county-wide moderate average, like Lake of the Woods County's, can still hide a specific house well above or below it — testing is what actually answers the question.

Testing and mitigation in Lake of the Woods County

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.
