Boxborough, Massachusetts, located within the 01719 ZIP code, currently carries a critical environmental hazard designation due to extensive localized industrial contamination. The area is surrounded by ten active environmental hazard sites within a five-mile radius, including the Agway/Kress Property located just under two miles from residential zones. This specific facility, alongside extraordinarily close active sites like the Shaffer Landfill, Watertown Bemis Dump, and the W.R. Grace Acton Plant, remains on the Environmental Protection Agency National Priorities List in an active assessment and remediation phase.

These facilities are associated with unspecified hazardous substances that historically involve volatile organic compounds, heavy metals, and industrial solvents from decades of unregulated manufacturing. When these persistent contaminants migrate into local soil aquifers and groundwater supplies, they pose severe exposure risks that can compromise human respiratory systems, disrupt endocrine function, and significantly increase the likelihood of chronic neurological and developmental disorders. Given the concentrated density of twenty-one total environmental hazard sites within a ten-mile radius, residents must implement strict protective measures immediately.

Households drawing their drinking supply from private wells must schedule comprehensive water testing through a state-certified laboratory to detect potential chemical intrusion before consumption. Residents should install activated carbon and high-efficiency particulate air filtration systems in their homes to mitigate airborne vapor intrusion originating from nearby soil off-gassing. Finally, individuals maintaining home gardens must exclusively utilize raised beds filled with imported, verified clean topsoil rather than planting directly into native ground, successfully preventing heavy metal bioaccumulation in homegrown produce.
