The Charlestown, Massachusetts, area within the 02129 zip code carries a critical environmental hazard designation due to extensive nearby industrial contamination. There are 16 registered hazard sites within five miles of this residential zone and 50 within ten miles. The most immediate threat originates from the Coal Tar Processing Facility (Former), located precisely one mile from the area. The EPA classifies this facility with an active status, indicating that comprehensive federal investigation and remediation efforts are currently underway but incomplete. Several other nearby active facilities, including the Monsanto Chemical Co. and the US Coast Guard Integrated Support Command, compound the local environmental burden. The primary contaminants of concern found at these sites are Polycyclic Aromatic Hydrocarbons (PAHs). These toxic chemical compounds originate from the historical processing and incomplete combustion of coal and oil. Human exposure to PAHs, whether through soil contact, groundwater consumption, or inhalation of contaminated particulate matter, significantly increases the risk of developmental disorders, skin irritation, and various cancers. Due to the active mitigation stage of the Coal Tar Processing Facility (Former), residents must implement immediate environmental safety protocols. Households should install certified reverse osmosis water filtration systems to intercept volatile organic compounds before tap water consumption. Furthermore, residents should strictly avoid planting edible gardens directly in native soil, utilizing raised beds filled with imported, certified-clean topsoil instead. Finally, individuals should utilize high-efficiency HEPA air purification systems indoors and routinely remove footwear upon entering homes to prevent the accumulation of contaminated soil dust tracked from the surrounding environment.
