Radon Mitigation in Lewisburg
High radon risk from Ordovician limestone of the Central Pennsylvania Ridge and Valley province. Lewisburg sits in a carbonate valley along the West Branch Susquehanna where the same Ordovician formations that produce elevated radon across the Nittany and Great Valleys extend into Union County. Bucknell University's consistent student rental turnover means a large fraction of the housing stock is occupied by transient residents, and much of the borough's pre-1980 housing has never been tested despite Union County's Zone 1 classification.
