1.1.1 Incident Category
1.1.2 Site Description
EPA’s Removal Program is conducting sampling to further evaluate the potential for vapor intrusion (VI) at several residential properties located on Bonair Avenue in Hatboro, Montgomery County, PA.
VI is the term used to describe the migration of volatile chemicals from subsurface contaminated soils and groundwater into the indoor air spaces of overlying buildings through openings in the building foundation. Common sources of VI include petroleum products, dry cleaning solvents, and other industrial solvents and degreasers.
EPA is coordinating with the Borough of Hatboro, the Pennsylvania Department of Environmental Protection (PADEP) and the Centers for Disease Control and Prevention (CDC)/Agency for Toxic Substances and Disease Registry (ATSDR).
1.1.2.1 Location
The Site is located in Hatboro, Montgomery County, Pennsylvania.
1.1.2.2 Description of Threat
The residences were initially sampled as part of ongoing investigations by EPA’s Remedial Program at the nearby Raymark Superfund Site. Based on the results of the initial sampling of indoor air, ambient (outdoor air) and sub-slab vapor, further investigation was recommended. Recent groundwater investigations conducted by EPA's Remedial Program suggest that the residences are not being impacted by contamination associated with the Raymark Superfund Site. EPA’s Removal Program is conducting sampling to determine whether VI is occurring in the residences, and if so, whether any of the chemicals detected present a potential health risk to the residents.
