Radon mitigation in Powell
What Powell homes mean for radon mitigation
Powell's post-1995 stock is dominated by full poured basements with sump pits already installed, many with a passive radon stack from the era's new-construction code that only needs a fan added to go active. Central Ohio's glacial till sits under all of Delaware County's EPA Zone 1 designation, so even homes with a ready passive stack commonly test above the action level. Older farmhouse-era pockets that predate Powell's growth are rarer here than in neighboring Delaware or Marysville and sit on shallower, less consistent foundations.
Powell straddles the Olentangy River, with the Olentangy Trail and its floodplain parks running through the middle of town.
