The Blue Swan Cleaners site is currently listed as an active National Priorities List location under EPA ID 110012647243. With 10 toxic sites within five miles and 92 within ten miles, Emerson residents face significant cumulative exposure risks. Primary exposure pathways include vapor intrusion from contaminated groundwater and direct contact with legacy industrial pollutants. These hazardous substances are linked to respiratory issues, neurological damage, and increased cancer risks over prolonged periods. The River Vale Radium site and Riverdale Brook Abandoned Drums further complicate the local environmental profile by introducing radiological and chemical runoff concerns into the watershed. To defend against these risks, residents must first install a high-quality carbon air filtration system to mitigate potential vapor intrusion from soil contaminants. Second, homeowners should utilize professional testing services for private well water or request annual water quality reports from municipal providers to check for volatile organic compounds. Third, maintain a physical barrier, such as raised beds with imported soil, for any home gardening to prevent direct contact with legacy industrial toxins in the ground. Constant vigilance regarding EPA cleanup updates is necessary as remediation efforts at these sites remain ongoing and complex across the Bergen County region.
