Radon risk in Martin County, FL

The EPA places Martin County, FL in Zone 3 - the EPA's lowest-risk category, with a predicted average indoor radon level below 2 pCi/L.

Lead paint risk in Martin County, FL

Census figures show 34% of homes in Martin County, FL were built before 1980, and 2% before 1950.
