About Sam
Sam Reynolds
Central Ohio radon specialist: the Ohio Shale geology behind Franklin County's numbers, the Ohio rules a correct install follows, and what actually brings a house down.
Sam Reynolds. Central Ohio radon specialist, focused on three things: the geology that puts every county around Columbus in EPA Zone 1, the Ohio rules that govern how a system is tested and installed, and what a fair scope of work looks like on the houses this region actually has.
The rules are a short stack of documents: the Ohio Radon Measurement Protocol and the Ohio Radon Mitigation Standards in OAC 3701-69, the licensing law in ORC Chapter 3723, the national ANSI/AARST MAH-2023 and SGM-SF-2023 standards, and the EPA guidance behind the 4 pCi/L action level. The geology is the Devonian Ohio Shale, which the USGS describes as the largest uranium source in the state and which runs in a north-south band beneath Franklin County, plus the soils weathered from the Columbus and Delaware limestones. Franklin County's 16,142 pre-mitigation tests from 2008 to 2017 had an estimated mean of 9.5 pCi/L in an American Lung Association analysis of CDC data.
The housing tells the rest: stone and brick foundations in Clintonville and German Village, postwar ranches in Whitehall and Reynoldsburg, split-levels in Hilliard, and new subdivisions from Powell to the Intel corridor, some with a builder's passive pipe waiting for a fan. Every page here ends in the same place: test the lowest level you use, and if the number calls for a fix, hire an Ohio-licensed mitigation contractor and read the proposal line by line.
