The Bailey’s Cleaners site, identified by EPA ID 110071100920, remains on the active National Priorities List. Environmental investigations focus on hazardous substances which often include volatile organic compounds. Exposure pathways primarily involve vapor intrusion, where chemical gases migrate from contaminated soil or groundwater into building foundations. Inhalation of these vapors poses long-term health risks, including potential nervous system damage and increased cancer risk. Groundwater contamination also threatens local aquifers, making untreated well water a significant ingestion risk. To defend against these hazards, residents should first install a high-quality carbon-based air filtration system to mitigate indoor vapor risks. Second, homeowners relying on private wells must conduct annual laboratory testing for volatile organic compounds. Third, maintain a physical barrier, such as clean fill or landscaping fabric, over exposed soil to prevent direct contact with legacy pollutants. The EPA continues to monitor the O’Connor Site and Quality Cleaners as part of the broader regional cleanup strategy. Compliance with local land-use restrictions is mandatory to prevent the accidental release of sequestered toxins during construction or excavation projects within the five-mile high-impact zone.
