What This Means

Hickman County, Tennessee is in EPA Radon Zone 1, the highest risk category. The EPA predicts average indoor radon levels greater than 4.0 pCi/L in this area — above the EPA action level. The EPA strongly recommends testing all homes in Zone 1 areas. If your home tests above 4.0 pCi/L, a radon mitigation system can reduce levels by up to 99%.

What You Should Do

1
Test your home immediately. Purchase a short-term radon test kit ($10–$30) or hire a certified professional. Place the test on the lowest livable level of your home.
2
If your test result is 4.0 pCi/L or higher, install a radon mitigation system. A qualified radon mitigator can install an active soil depressurization system for $800–$1,500, reducing levels by up to 99%.
3
Re-test within 24 hours of installation to confirm the system is working, then test again every 2 years to ensure continued effectiveness.

Radon & Your Basement in Hickman County

Hickman County is in EPA Zone 1, the highest risk category. Basements and ground-level rooms in this area are very likely to have elevated radon concentrations. If your home has a basement, it should be your first testing location.

Radon concentrations are typically highest in the lowest level of a home. However, radon does not stay confined to the basement — it migrates to upper floors through stairways, HVAC ducts, and gaps in flooring. Even if your basement is unfinished or rarely used, elevated radon there can affect the air quality on your main living floors. Always test on the lowest livable level.
