Radon Mitigation Systems in Galena, OH

Radon Mitigation Systems in Galena involves sub-slab depressurization with an inline radon fan, sealed slab penetrations, and an exterior discharge stack above the eave line, working on the slab-to-soil interface and any below-grade openings where soil gas enters the home. The service is the standard installation for any Columbus home testing above the EPA action level of 4.0 pCi/L on a 90-day or annual long-term average.

Galena's old village core along Hoover Reservoir has older basements, some stone or block, built well before any radon code existed, while the newer subdivision ring around the village follows the post-1995 pattern of poured basements with sumps and passive stacks. Soil-gas entry differs by generation: the older stock takes on gas through the wall as much as the slab, while the newer stock is a cleaner sub-slab suction candidate. Delaware County's glacial till keeps the whole village inside EPA Zone 1. Galena sits directly on the shore of Hoover Reservoir, the Big Walnut Creek impoundment that supplies much of Columbus's drinking water. Galena sits on geology that drives elevated regional radon exposure across the Columbus metro, including Delaware County.

Delaware County's glacial till keeps the whole county in EPA Zone 1 regardless of foundation age, but the install itself differs: the historic limestone-and-block stock near downtown Delaware and Ohio Wesleyan needs a more deliberate seal at the foundation wall, while the US 23 growth corridor through Powell and Lewis Center offers ready sump pits for a single-point install.

Mitigation systems installed in Ohio must meet ANSI/AARST CCAH-2020-0523 for existing dwellings and be installed by a contractor licensed under ORC 3723.02 (Ohio Department of Health Radon Licensing Program). The Ohio Department of Health Radon Licensing Program oversees radon program compliance for Galena, and Ohio licensure under ORC 3723.02 applies to any contractor performing mitigation work in the state.
