The zip code 01581 in Westborough, Massachusetts, carries a critical environmental hazard designation due to significant industrial contamination. This area contains ten active environmental hazard sites within a five-mile radius and twenty within ten miles. The nearest major concern is Barys Land/31 Rydberg Terrace, located 3.5 miles away. This site holds an active status on the National Priorities List, indicating that the Environmental Protection Agency is currently conducting ongoing remediation and long-term cleanup phases. Additional active industrial sites, such as Towne and Country Dry Cleaners located just 0.88 miles away, further compound local environmental pressures.

The primary contaminant of concern across these locations is tetrachloroethylene, commonly known as PCE or PERC. PCE is a volatile organic compound frequently utilized in dry cleaning and metal degreasing operations. When this chemical infiltrates groundwater or vaporizes into the air, it poses severe health risks. Prolonged exposure to PCE affects the central nervous system, liver, and kidneys, and it is classified as a likely human carcinogen. Vapor intrusion, where chemical gases seep from contaminated groundwater into residential basements, remains a distinct threat for local properties.

Due to these active environmental risks, residents should implement immediate safety measures. Individuals utilizing private wells must conduct annual water testing specifically screening for volatile organic compounds to ensure their drinking water remains uncontaminated. Homeowners living in close proximity to the aforementioned active sites should install certified sub-slab depressurization systems to mitigate potential vapor intrusion. Finally, residents should install air purifiers equipped with heavy-duty activated carbon filters to effectively capture airborne volatile organic compounds indoors.
