South Carolina's radon program data shows why the county is worth watching: 5,220 initial home tests through June 2022, an average of 3.4 pCi/L, and a top reading of 126.6. The national indoor average is about 1.3 pCi/L, and outdoor air runs around 0.4.
Radon levels change from one lot to the next, so the EPA recommends testing every home. Its action level is 4 pCi/L, and it suggests considering mitigation between 2 and 4. The EPA estimates radon is the second leading cause of lung cancer overall.
Travelers Rest grew about 70% between 2010 and 2020, from a small town into a growing community of about 9,100 residents by 2025. Furman University was annexed into the city in 2018. Plenty of new homes have gone up, along with established houses in and around town.
Newer homes in Greenville County are built under a residential code that includes radon-control methods, often a passive vent pipe. Older homes vary. Many Upstate homes sit on crawl spaces or slabs, and older homes may have basements. Crawl spaces usually get a sealed membrane with a fan drawing beneath it. Slabs and basements usually get sub-slab depressurization.
Radon can also show up in well water. If your home in or around Travelers Rest is on a private well, a water test is worth adding. When it's high, a water treatment system removes radon before it's released indoors. Typical range: $1,200–$5,000.

It can. Radon dissolves into groundwater and is released into indoor air when you shower, wash dishes or run laundry. If your home uses a private well, ask for a water radon test along with an air test. If levels are high, aeration or other treatment systems remove it, typically $1,200–$5,000 as an estimate.
Not in a way you can predict. Radon comes from the soil and rock under each home, so levels vary lot by lot no matter the altitude. What matters is that Travelers Rest is in Greenville County, the state's only EPA Zone 1 county. A test is the only reliable way to know your home's level.
Radon fans run nonstop but use modest power, typically about $30–$300 a year in electricity, with most homes at the lower end. Fans usually last five to ten years. We size the fan for your home and foundation so it moves enough air to do the job without running harder than needed.
