The Andover, Massachusetts zip code area 01810 carries a critical environmental hazard designation due to extensive nearby industrial contamination. Within a ten-mile radius, fifty-one hazard sites are tracked, including seven within just five miles. Prominent among these is the GENCORP Superfund site, located 4.3 miles from the zip code center, alongside closer facilities like Tewksbury Auto Parts and Sutton Brook Disposal Area. The Environmental Protection Agency currently lists GENCORP and several surrounding locations as active sites on the National Priorities List. This active status indicates that site assessment, containment, or long-term remediation efforts remain ongoing, and the area has not yet been cleared for unrestricted public use.

The EPA categorizes the primary pollutants at these facilities as unspecified hazardous substances. In industrial regions matching this profile, such classifications typically encompass volatile organic compounds, heavy metals, and legacy industrial solvents. Environmental exposure to these agents through groundwater migration or soil vapor intrusion can significantly increase resident risks for neurological disruption, chronic respiratory illness, and certain cancers over prolonged periods. To mitigate potential exposure risks, residents should implement specific household safety protocols immediately. Individuals relying on private wells must schedule annual water testing through a state-certified laboratory to thoroughly screen for volatile organic compounds and dissolved metals. Residents should also install high-efficiency particulate air filters in home ventilation systems to capture airborne industrial particulates. Finally, households must monitor local municipal water quality reports annually and utilize point-of-use reverse osmosis filtration systems for drinking water if local municipal sources indicate elevated contaminant thresholds.
