The 02138 zip code area of Cambridge, Massachusetts, carries a critical environmental hazard designation due to a high density of legacy industrial contamination. The Environmental Protection Agency currently monitors fifty-four hazardous waste facilities within ten miles of this community, with fourteen sites located within just five miles. The Former Coal Tar Processing Facility represents a primary regulatory focus situated 4.2 miles away. This location maintains an active status on the National Priorities List, meaning the EPA is actively executing long-term remedial investigations and implementing engineered cleanup operations to contain ongoing environmental threats. Other active remediation zones impacting the immediate vicinity include Conway Park, the Watertown MGP, and the Materials Technology Laboratory.

While the EPA classifies the primary contaminants at the Former Coal Tar Processing Facility as unspecified hazardous substances, coal tar and munitions sites historically release volatile organic compounds, heavy metals, and polycyclic aromatic hydrocarbons into the environment. Chronic exposure to these industrial pollutants through soil vapor intrusion or the inhalation of contaminated particulate matter can increase the risk of respiratory diseases, neurological damage, and systemic organ toxicity. To immediately mitigate potential exposure vectors, residents should install certified HEPA air filtration systems in their dwellings to capture airborne contaminants. Individuals should also commission independent soil testing before cultivating edible vegetation and rely exclusively on raised garden beds filled with certified clean topsoil. Furthermore, residents should implement reverse osmosis water filtration systems at point of use faucets to protect household drinking water against migrating groundwater contamination plumes.
