Arlington, Massachusetts, within the 02474 zip code, carries a critical environmental hazard designation due to extensive nearby industrial contamination. The area sits in proximity to 13 hazardous sites within a five-mile radius and 58 sites within ten miles. The most prominent EPA Superfund location, Atlantic Gelatine, operates under an active National Priorities List status approximately 4.5 miles away. Other notable active sites include Duffy Bros Construction Inc, Conway Park, and the US Army Materials Technology Laboratory.

Atlantic Gelatine and surrounding facilities are monitored for unspecified hazardous substances. While the exact chemical profiles vary by facility, industrial byproducts in this region typically involve heavy metals, volatile organic compounds, and soil leachates. Exposure to these unmitigated hazardous substances can lead to respiratory irritation, neurological disruption, and cumulative organ toxicity through prolonged ingestion or inhalation of contaminated particulate matter. Because Atlantic Gelatine and neighboring sites maintain active EPA status, they are currently undergoing comprehensive remedial investigation, risk assessment, and active cleanup phases. Federal and state agencies are actively monitoring local groundwater plumes and soil vapor intrusion pathways to contain migrating pollutants.

Given the high concentration of active remediation zones, Arlington residents should implement immediate safety measures. Individuals utilizing private wells must conduct comprehensive annual water testing for heavy metals and volatile organic compounds. Households should install certified high-efficiency particulate air filtration systems to mitigate airborne dust migration from nearby industrial operations. Finally, residents should verify the origin of local landscaping topsoil and utilize raised garden beds with imported, certified-clean soil for all agricultural activities.
