Is Haskell County, TX a radon risk area?

EPA places Haskell County in Zone 3 - Low Potential — a predicted county-wide average indoor radon level below 2 pCi/L, based on the geology, soil and aerial radioactivity data behind EPA's national map. Haskell County sits at the 3rd percentile nationally for radon potential — above 3 of every 100 rated counties.

How Haskell County compares

About 5,435 people live in Haskell County, Texas, spread over 903.133 square miles. That works out to roughly 6 people per square mile. Rank 932 by population within its EPA zone puts Haskell County at the 10th percentile among zone peers. Haskell County falls in EPA Radon Region 6, one of 503 counties nationally EPA assigns to that same geologic province.

Why the zone isn't the answer by itself

Haskell 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. A Zone 3 rating means Haskell County's county-wide average is predicted low, but EPA is explicit that a meaningful share of homes in low-potential zones still test above the action level — a low zone is not a reason to skip testing.

If Haskell County tests above the action level

Nothing about Haskell County's EPA zone changes the mitigation number: $800–$2,500 nationally (around $1,200 typical), set by the house's foundation rather than the county it sits in — and only relevant once a test actually clears 4 pCi/L.
