The Boston, Massachusetts zip code 02202 currently carries a critical environmental hazard designation due to extensive industrial contamination. The primary area of concern is the Coal Tar Processing Facility (Former), located 2.3 miles away, operating under an active National Priorities List status. This localized area features severe industrial density, with 16 regulated environmental sites within a five-mile radius, including the US Coast Guard Integrated Support Command situated just 0.62 miles away. The Environmental Protection Agency cites unspecified hazardous substances at the primary site. In the context of coal tar processing, these historically include volatile organic compounds, polycyclic aromatic hydrocarbons, and heavy metals. Exposure to these industrial compounds through soil vapor intrusion, particulate inhalation, or incidental contact can increase the risk of respiratory distress, neurological impairment, and chronic systemic illnesses in humans. Because the facility maintains an active National Priorities List status, the Environmental Protection Agency is actively enforcing long-term remedial investigations and engineered cleanup phases to mitigate continuous contaminant migration into surrounding commercial and residential zones.

Given the proximity to 43 total hazardous sites within ten miles, residents must implement immediate environmental safeguards to reduce exposure risks. Residents should install certified high-efficiency particulate air filtration systems in their dwellings to mitigate indoor accumulation of airborne volatile compounds. Individuals should also utilize certified point-of-use reverse osmosis water filtration systems rated for heavy metals and industrial chemicals. Finally, residents should avoid disturbing deep soil during residential landscaping and thoroughly wipe down footwear before entering homes to prevent tracking contaminated particulate matter indoors.
