What Radon Level Requires Active Mitigation in Georgia?
The EPA strictly mandates that indoor radon concentrations of 4.0 picoCuries per liter (pCi/L) or higher require active mitigation in Georgia. The EPA also recommends considering mitigation if levels test between 2.0 and 4.0 pCi/L. In Georgia real estate contracts, a verified test of 4.0 pCi/L or higher provides standard contractual grounds to request that the seller install an active sub-slab depressurization mitigation system (typically costing $1,200 to $1,800) prior to closing.
Understanding Continuous Electronic CRM Testing
Passive charcoal canisters take days to mail to out-of-state labs and cannot detect environmental tampering. Foresight deploys continuous electronic radon monitors (CRM) that record hourly radon levels, barometric pressure, temperature, and relative humidity for 48 uninterrupted hours.
How Active Sub-Slab Depressurization Works
An active radon mitigation system consists of a PVC extraction pipe inserted through the concrete slab into aggregate gravel, routed outside to an inline exhaust fan that safely expels radon above the roofline before it enters living spaces.
Negotiating Seller Remediation in Georgia
Because radon mitigation is an established, non-controversial repair with fixed pricing, Georgia sellers almost always agree to install a system or issue a $1,500 credit when presented with certified electronic CRM lab curves.
"A 4.0 pCi/L radon level carries roughly the same lung cancer risk as smoking half a pack of cigarettes daily. The good news is that active mitigation reduces levels below 1.5 pCi/L with 99% efficacy."
