Charlton City, Massachusetts, ZIP code 01508, currently carries a critical environmental hazard designation due to concentrated industrial contamination. The area sits within five miles of three active National Priorities List locations, with the nearest being DB COTTON at 0 GUELPHWOOD RD, located 3.9 miles away. Additional active DB COTTON sites operate within a similar radius, while the Mace Polymer Fire and Spencer Transfer Station sites lie within ten miles.

The EPA lists the primary contaminants at these facilities as unspecified hazardous substances. Human exposure to these mixed industrial waste materials typically occurs through ongoing groundwater leaching into local aquifers or widespread airborne particulate dispersion. Long-term contact with these environmental compounds can impair respiratory function, disrupt neurological development, and elevate the risk of chronic systemic illnesses. These designated facilities retain an active status on the EPA National Priorities List, explicitly indicating that comprehensive remediation efforts, environmental monitoring protocols, and critical site assessments remain ongoing without final closure.

Given the immediate geographic proximity to these five active Superfund locations, local residents should implement strict household environmental safeguards. Households utilizing private wells must schedule annual water quality testing through state-certified laboratories to detect heavy metals and volatile organic compounds. Residents should also install high-efficiency particulate air filtration systems in their homes to mitigate potential inhalation risks from migrating surface dust. Finally, all individuals planting outdoor residential vegetable gardens must utilize constructed raised beds filled with imported, certified-clean topsoil rather than planting directly into native ground to prevent dietary exposure to subsurface soil contamination.
