Worcester, Massachusetts, within the 01602 zip code area, currently holds a critical hazard designation due to extensive industrial contamination. The area is surrounded by nineteen monitored environmental hazard sites within a ten-mile radius, including nine sites within just five miles. The nearest major facility, Barys Land/31 Rydberg Terrace, sits 4.6 miles away and maintains an active status on the EPA National Priorities List. This indicates that federal assessment and cleanup operations are currently underway but remain incomplete. The primary contaminant of concern across this zone is Tetrachloroethylene, commonly known as PCE or PERC. PCE is a volatile organic compound historically used in dry cleaning and metal degreasing. Exposure to PCE occurs primarily through vapor intrusion into building foundations or contaminated groundwater consumption. Prolonged exposure can cause neurological impairment, liver and kidney damage, and increased cancer risk. Other active remediation sites in close proximity, such as Towne and Country Dry Cleaners located just 1.04 miles away, compound the regional PCE vapor intrusion threat.

Given the active status of Barys Land/31 Rydberg Terrace and the high concentration of adjacent industrial sites, residents must implement specific environmental health safeguards. Individuals utilizing private wells must conduct annual water testing specifically for volatile organic compounds, as municipal testing does not cover private groundwater supplies. Residents should install certified volatile organic compound water filtration systems at the point of entry to prevent dermal and ingestion exposure. Furthermore, property owners should hire certified environmental professionals to test basement air quality for PCE vapor intrusion and install sub-slab depressurization mitigation systems if elevated chemical levels are detected.
