Where Sawyer County sits nationally

Sawyer County, Wisconsin is home to about 18,835 people across 1,257.604 square miles. Population density there runs about 15 people per square mile.

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

Testing and mitigation in Sawyer 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.
