Compare your estimate with the cost calculatorEPA Zone / County Risk
Primary state-level EPA reference: Zone 1. Much of Connecticut is Zone 1, particularly areas along the Reading Prong geological formation that runs through the state.
EPA zone maps are county-level screening tools. Home-level testing is still required to confirm risk.
When to Test in Essex
Connecticut is generally mapped as higher-potential radon territory (Zone 1), so annual-to-biannual testing is common after mitigation or major foundation changes. For seasonal timing, closed-house winter testing usually captures worst-case indoor buildup. For real-estate transactions, run a short-term test during due diligence, then confirm with follow-up testing if results are near or above 4.0 pCi/L.
