Radon Mitigation in Hartford, CT

Radon Mitigation in Hartford, Connecticut

Hartford and the surrounding Capitol Region — including West Hartford, Glastonbury, Simsbury, and Farmington — sit in EPA Radon Zone 2, with pockets of Zone 1 in northern and central Connecticut. Connecticut's statewide average of approximately 3.7 pCi/L masks significant local variation: the crystalline bedrock of central Connecticut produces more radon than coastal areas, and many Hartford-area homes test above the 4 pCi/L EPA action level.

Why Hartford-Area Homes Test High

Connecticut's radon risk is driven by geology. The Hartford Basin is underlain by Triassic red sandstone and basaltic traprock ridges — formations that generate elevated radon in many areas. Simsbury, Avon, and Farmington, situated near traprock ridges, consistently produce high test results. Even urban Hartford, with its aging housing stock of pre-1940 multi-family homes, shows elevated levels due to foundation age and permeability.

New England's cold winters also concentrate radon indoors. Homes are sealed tightly from October through April, and many Connecticut homes show meaningfully higher indoor concentrations in heating months than in summer.
