Adelphi sits on the western edge of the Allegheny Plateau, where Mississippian and Devonian shale formations create exactly the kind of uranium-bearing bedrock that off-gasses radon. Tight modern construction, gravity foundations on older Adelphi farmhouses, and unfinished commercial slab-on-grade buildings along Main Street all share one thing: they pull soil gas upward and trap it indoors.

We have tested properties from historic commercial buildings near the Salt Creek corridor to newer multi-tenant builds outside the village limits. Readings of 8–15 pCi/L are not unusual here. We have seen apartment ground-floor units in nearby Laurelville test north of 20 pCi/L. None of that should scare you — it is a fixable problem with a well-understood engineering solution. That is the entire point of hiring a licensed mitigator.
