The Aetna Chemical Corp site, EPA ID 110070727011, is currently an active site on the National Priorities List. Contaminants at this location and nearby sites like Allied Textile Printing and Galaxie Chemical Corp include unspecified hazardous substances that migrate through groundwater and soil vapor. Exposure pathways in Paterson primarily involve the inhalation of volatile organic compounds in indoor air and ingestion of heavy metals in soil. Prolonged exposure increases risks for respiratory illness, neurological damage, and certain cancers. Regulatory monitoring is ongoing, yet the high density of 138 sites within ten miles indicates cumulative industrial impact. Residents must adopt defensive measures to mitigate risk. First, install high-efficiency particulate air (HEPA) filters in homes to capture airborne contaminants. Second, use certified water filtration systems that meet NSF/ANSI standards for chemical removal. Third, remove shoes before entering living spaces to prevent the tracking of contaminated exterior soil into the home. These steps address the primary routes of hazardous entry into the domestic environment while federal remediation efforts continue.
