Radon testing on Potomac's larger lots
Potomac's housing stock skews toward larger lots and lower density than most of the rest of Montgomery County. Communities like Avenel, built around the TPC Potomac golf course, mix estate homes with some attached and smaller-lot housing, while River Falls and Potomac Falls are defined by multi-acre lots, mature trees, and more private setbacks from the street. Closer to Potomac Village, lot sizes shrink and homes date back further.
One practical difference in Potomac: according to Montgomery County's own Department of Environmental Protection, the county's lower-density, outer areas — which include parts of Potomac — often rely on private wells and septic systems rather than public water and sewer, since utility lines don't reach every property. That doesn't change how a radon test works, but it's a good reminder that no two Potomac properties are quite the same, which is exactly why testing the specific home (not assuming based on a neighbor's result) is the only way to know.
