Radon Testing in Galena, OH

Radon Testing in Galena involves short-term (2-7 day) charcoal canister or continuous radon monitor placement on the lowest occupied level, working on the lowest lived-in level of the home where occupants spend more than 4 hours per day. The service is the first step for any home that has not been tested in the last 2 years, for any home being sold, and for any home after a significant foundation, basement, or HVAC modification.

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 testing behaves consistently across EPA Zone 1 regardless of which half of the county a house sits in, though the older limestone-and-block downtown stock near Ohio Wesleyan warrants closer attention to sealing gaps around the foundation during the closed-house window than the newer sump-equipped construction along US 23.

ANSI/AARST MAH-2023 establishes the residential measurement protocol. Closed-house conditions must be maintained throughout short-term testing. 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.
