Oxford, Massachusetts, encompassing ZIP code 01540, carries a critical environmental hazard designation due to the dense proximity of nineteen regulated contamination sites within a ten-mile radius. The immediate area contains three active sites within five miles, with the most significant threat being the Empire Cleaners (Former) Superfund site located 4.46 miles away. The Environmental Protection Agency maintains this location (EPA ID: 110071432882) on the active National Priorities List, indicating that the facility is currently undergoing long-term remediation and complex groundwater cleanup phases. The primary contaminants at the Empire Cleaners (Former) site involve unspecified hazardous substances, which typically include volatile organic compounds and commercial dry-cleaning solvents. When these industrial chemicals migrate through subsurface groundwater or emit soil vapor, they can severely affect residents by increasing the risk of respiratory distress, neurological impairment, and chronic systemic illnesses during prolonged exposure. Other nearby active hazard sites, such as the Mass 10 Truck Stop, Webster MGP Location, and Fournier Lagoon, further compound local environmental vulnerability.

To protect public health against these active hazards, residents should implement immediate protective measures. First, residents relying on private wells should test their water supply biannually for volatile organic compounds and industrial solvents, as standard municipal testing excludes private infrastructure. Second, households should install certified activated carbon filtration systems on all primary drinking water taps to intercept potential legacy groundwater pollutants. Finally, residents should independently monitor indoor air quality using professional vapor intrusion testing kits, particularly in lower-level basements where hazardous soil vapors most frequently accumulate.
