The zip code area 01604 in Worcester, Massachusetts, currently holds a critical environmental hazard designation due to severe industrial pollution proximity. Residents live within a five-mile radius of nine active toxic waste sites, with twenty-two facilities located within ten miles.

The most prominent concern is the Barys Land/31 Rydberg Terrace facility, located just 2.8 miles away. The Environmental Protection Agency currently classifies this location as an active National Priorities List site, indicating that federal assessment and long-term remediation efforts remain ongoing. Additional nearby active sites include the MA Army National Guard, Wright Machine Corp, Grafton Dry Cleaners, and Rexnord Inc Roller Chain Div facilities.

The primary threat stems from unspecified hazardous substances prevalent in historical industrial dumping. While specific chemical profiles vary across these active sites, unspecified hazardous substances typically include heavy metals, volatile organic compounds, and industrial solvents. Prolonged exposure to these compounds through airborne particulate inhalation, contaminated soil contact, or groundwater intrusion can severely affect residents by causing respiratory illnesses, neurological impairment, and elevated long-term cancer risks.

Given the high density of active environmental threats, residents must implement protective measures immediately. First, individuals should install certified high-efficiency particulate air filtration systems in their homes to mitigate indoor inhalation risks. Second, residents consuming well water must schedule immediate private laboratory testing for heavy metals and volatile organic compounds. Finally, households should avoid planting edible gardens directly in native topsoil, utilizing raised beds with imported soil to prevent potential dermal contact and ingestion of legacy contaminants.
