Bowling Green sits on the karst plateau of south-central Kentucky — the Mammoth Cave region — where sinkholes, conduits, and underground streams transport radon gas laterally and concentrate it under homes. Warren County tests have averaged 14.0 pCi/L (the 4th-highest county average in Kentucky), and Bowling Green-specific user-submitted tests have averaged 15.8 pCi/L. The city is a published case study for radon in karst landscapes (Western Kentucky University thesis #1682).
Geology: Bowling Green's milder winters (south-central KY) mean stack-effect-driven radon is secondary to the city's karst geology, which transports radon gas through limestone conduits regardless of season.
Permits: Kentucky does not require a state-level radon mitigation permit. Bowling Green standard building permits may apply for exterior penetrations.
Neighborhoods we serve in Bowling Green: Briarwood Manor, Fieldstone Farms, Shawnee Estates, CrossRidge, Springhill, Barren River area.
All Bowling Green radon work is performed by NRPP-certified, KBRS-registered partner contractors routed through Kentucky Radon Experts.

| EPA Radon Zone | Zone 1 | Zone 1 (30 of 120 counties; 60% of population) | Varies (Zones 1–3) |
| % homes elevated (>4 pCi/L) | 70% | ~33% (1 in 3) | ~6% |

Learn more →Kentucky Revised Statute § 324.360 requires sellers to disclose any known radon test results to buyers. In practice, most Bowling Green real estate transactions now include a radon contingency in the purchase agreement — and given that 70% of Bowling Green homes test elevated, buyers are increasingly insisting on pre-closing mitigation when results exceed 4 pCi/L.
Our partner contractor network handles closing-timeline mitigations within typical 7–14 day windows, including post-mitigation verification testing to satisfy lender and inspector requirements.
Yes. Bowling Green's cold winters intensify radon entry through the stack effect — heated indoor air rising creates negative pressure in basements that pulls soil gas into the home at higher rates than warmer climates. Bowling Green winter radon readings are typically 30–50% higher than summer readings.
EPA recommends radon testing under closed-house conditions, which align naturally with Bowling Green winters. If your Bowling Green home tested low in summer, retest in winter for an accurate baseline before deciding on mitigation.
