Certified Radon Mitigators
in Bloomington, Indiana

Bloomington and Monroe County sit in southern Indiana, where Mississippian limestone karst terrain transitions from the high-glacial-till areas of central Indiana. Southern Indiana's karst geology creates variable radon conditions — some areas test very low, while homes over fractured limestone with good soil-gas communication can see readings well above the action level. Monroe County is EPA Zone 2, but individual Bloomington homes in older neighborhoods near Indiana University and on the city's wooded southern slopes should still be tested. Indiana's 5.6 pCi/L statewide average understates risk in the better-connected karst zones. Indiana-certified contractors serve the Bloomington market from Indianapolis and the Louisville metro.
