The North Castle Cleaners site, EPA ID 110009271377, maintains an active status on the National Priorities List. Primary contamination involves fibrous asbestos minerals. Exposure pathways typically occur through the inhalation of airborne fibers or the ingestion of contaminated dust particles. Health risks associated with this site include asbestosis, lung cancer, and mesothelioma, as these minerals lodge permanently in lung tissue. The EPA continues to monitor the site to prevent further migration of contaminants into the surrounding Greenwich environment. To minimize personal risk, residents should implement three defensive measures. First, hire certified professionals for any home renovations involving materials installed before 1980 to prevent fiber release. Second, maintain high-efficiency particulate air filtration systems within the home to capture potential microscopic particulates. Third, avoid disturbing soil or debris near known remediation zones to prevent tracking contaminants into living spaces. Continuous oversight by federal authorities is required to manage the active hazards present at this and the eight other identified sites within a ten-mile radius, including the Anderson Hill Asbestos Site and Port Refinery.
