Arlington Heights, Massachusetts, within the 02475 zip code, currently holds a critical environmental hazard designation due to extensive nearby industrial contamination. The area sits in close proximity to a high concentration of hazardous waste facilities, with ten active sites within a five mile radius and twenty one within ten miles. Notably, the Agway/Kress Property, an active Superfund site, is located just under two miles away, while the Shaffer Landfill and Watertown Bemis Dump operate within a fraction of a mile. The Environmental Protection Agency cites unspecified hazardous substances as the primary contaminants of concern in this region. Because the exact chemical composition remains broadly categorized, exposure to these industrial wastes typically occurs through groundwater leaching, soil vapor intrusion, or airborne particulate inhalation. Extended contact with such uncharacterized industrial pollutants can lead to respiratory irritation, neurological distress, and an elevated risk of chronic systemic illnesses.

The Agway/Kress Property and surrounding facilities remain on the active National Priorities List, indicating that the agency considers them significant threats requiring ongoing federal remedial action. These sites are currently in active cleanup and continuous monitoring stages, meaning environmental containment efforts are underway but site mitigation is not yet complete. Given the density of active contamination zones, residents must take immediate precautionary measures. Households should install certified reverse osmosis water filtration systems immediately to block potential chemical groundwater intrusions. Furthermore, residents should permanently seal all basement foundation cracks to prevent harmful soil vapor intrusion and continuously operate particulate air purifiers to capture localized airborne industrial pollutants.
