Radon in Cumming, Georgia: What Forsyth County Homeowners Need to Know
Cumming is the county seat and only incorporated city in Forsyth County, one of the fastest-growing counties in the United States. With a county population exceeding 280,000 and thousands of new homes built each year, radon awareness in this area is critical. The underlying Piedmont granite bedrock that stretches beneath Cumming and all of Forsyth County naturally contains uranium, which decays into radon gas.
According to data collected by the UGA Radon Program between January 2020 and May 2025, nearly 1 in 5 homes tested in Forsyth County had radon levels above the EPA action level of 4.0 pCi/L. The county recorded a high reading of 17.8 pCi/L, more than four times the EPA threshold. Forsyth County is classified as EPA Zone 2 with a predicted average screening level between 2 and 4 pCi/L, but actual test results frequently exceed this range.
Radon is the second leading cause of lung cancer in the United States. In Georgia alone, approximately 800 people die each year from radon-related lung cancer. Radon is the leading cause of lung cancer among non-smokers, and people who smoke and are exposed to radon face 10 times the risk. Because radon is odorless, colorless, and tasteless, the only way to know your home's radon level is through testing.
Whether you live in a new subdivision in South Forsyth, an established neighborhood near Downtown Cumming, or a home along the shores of Lake Lanier, your property's radon levels depend on the specific soil and rock beneath your foundation. Testing is the only way to find out.
Forsyth County Geology and Radon Risk
Forsyth County sits within the Piedmont physiographic province on a formation known as the Powers Ferry metagraywacke. According to geological research presented to the AARST, this formation and the surrounding granites contain significant amounts of uranium that appear on National Uranium Resource Evaluation (NURE) maps. The same geological formation extends across East Cobb, North Fulton, and all of Forsyth County.
Despite sharing essentially identical geology with Zone 1 counties like Cobb and Fulton, Forsyth County carries a Zone 2 designation. This means the EPA prediction may underestimate actual radon levels in Cumming homes. Real-world testing data from the UGA Radon Program confirms this, with Forsyth County recording the highest single radon reading among 13 Georgia counties studied.
Radon Testing Across Cumming & Forsyth County Communities
Forsyth County's rapid growth means a wide range of housing types, from brand-new master-planned communities to established neighborhoods and rural properties. Each faces radon risk from the same underlying granite bedrock.
New Construction & Subdivisions
Forsyth County is one of the fastest-growing counties in the nation with thousands of new homes built annually. Communities like Vickery, Sharon Springs, Windermere, and Polo Fields are built directly on granite bedrock that produces radon gas.
New construction does not mean radon-free. Modern homes with tight building envelopes can actually trap radon more effectively than older, draftier homes. Testing is essential even in brand-new Cumming homes.
Established Neighborhoods
Older neighborhoods in and around Downtown Cumming, Coal Mountain, and the Highway 9 corridor include homes with basements and crawl spaces that are particularly susceptible to radon entry.
Homes with basements on Forsyth County's granite bedrock often test higher for radon. Cracks in foundation walls, gaps around pipes, and sump pits provide pathways for radon gas to enter your living space.
Homes on Well Water
Many Forsyth County homes outside Cumming city limits rely on private wells. According to UGA research, wells drilled into Georgia's northern granite aquifers average 8,000 pCi per liter of radon in water, compared to 200-600 pCi/L in other groundwater.
Radon in well water releases into the air when you shower, wash dishes, or do laundry. Homes on well water in Forsyth County should test for both airborne and waterborne radon.
Schools, Daycares & Commercial
Forsyth County Schools serves approximately 55,000 students across 42 schools. Children are especially vulnerable to radon exposure. Commercial buildings, daycares, and offices on Forsyth County's granite bedrock should be tested.
We provide commercial radon testing and mitigation services for Cumming-area businesses, schools, and multi-family properties with compliance documentation.

Frequently Asked Questions About Radon in Cumming, GA
Common questions from Forsyth County homeowners about radon testing and mitigation
Why is radon a concern in Cumming and Forsyth County?
Cumming sits in Georgia's Piedmont region on granite bedrock that naturally contains uranium. As uranium decays, it produces radon gas that migrates through cracks in rock and soil into homes. According to UGA Extension data collected from 2020 to 2025, nearly 1 in 5 homes tested in Forsyth County had elevated radon levels, and the county recorded a high reading of 17.8 pCi/L—more than four times the EPA action level of 4.0 pCi/L.
What is the average radon level in Cumming, GA?
Forsyth County is classified as EPA Zone 2 with a predicted average indoor screening level between 2 and 4 pCi/L. However, actual test results in the Cumming area frequently exceed this prediction, with reported averages around 4.5 pCi/L—above the EPA's recommended action level. Individual homes can test significantly higher depending on foundation type, soil conditions, and construction.
Should I test for radon if my home is newly built in Cumming?
Yes. New construction in Cumming and greater Forsyth County faces the same radon risk as older homes. The underlying granite geology affects all properties regardless of age. Forsyth County's rapid growth means thousands of new homes are built each year on land with radon-producing granite bedrock. The EPA recommends testing all homes, including new construction, and retesting every two years.
How much does radon mitigation cost in Cumming?
Radon mitigation systems in Cumming typically cost between $1,200 and $2,500 for standard residential installations. The final cost depends on your home's foundation type, size, and the complexity of the system required. Sub-slab depressurization is the most common and effective method for Cumming homes. We provide free estimates so you know the cost before any work begins.
Is radon in well water a concern in Forsyth County?
Yes. Many Forsyth County homes rely on private wells drilled into granite aquifers. According to UGA research, granite aquifers in northern Georgia average 8,000 pCi per liter of radon in water—dramatically higher than the 200-600 pCi/L found in other groundwater sources. If your Cumming home uses well water, testing for waterborne radon is recommended in addition to indoor air testing.
How long does radon testing take in Cumming?
Short-term radon tests take 48 to 96 hours and provide a snapshot of your home's radon levels. We use professional continuous radon monitors that record hourly readings for the most accurate results. For real estate transactions in Cumming, we offer 48-hour turnaround to keep deals on schedule.
What type of radon mitigation system works best for Cumming homes?
Sub-slab depressurization (SSD) is the most effective radon remediation method for Cumming homes. The system creates negative pressure beneath your foundation to intercept radon before it enters your living space. For homes with crawl spaces, sub-membrane depressurization is used instead. Both approaches are effective at reducing radon levels well below the EPA action level.
Do I need to test for radon before selling my Cumming home?
While Georgia does not legally require radon testing for home sales, most buyers in Forsyth County request it as part of the inspection process. Given Forsyth County's documented radon levels, providing a recent test or having a mitigation system installed can strengthen your listing and prevent delays during closing.
