Sherborn, Massachusetts (ZIP code 01770), currently holds a critical environmental hazard designation due to extensive proximity to multiple active Superfund locations. The area lies within five miles of ten distinct contaminated facilities and twenty-one sites within ten miles. The most pressing regulatory concern is the Agway/Kress Property, an active site located approximately 1.9 miles from the center of the zip code. Additional high-priority facilities immediately impacting the boundary include Shaffer Landfill and Watertown Bemis Dump, both situated mere fractions of a mile away.

The Agway/Kress Property and surrounding locations are currently under active EPA regulatory management and remediation for unspecified hazardous substances. While specific chemical profiles are unlisted, industrial mixtures of this classification typically contain volatile organic compounds, heavy metals, or industrial solvents. Chronic exposure to these legacy industrial pollutants through groundwater migration or vapor intrusion can severely impact local public health, potentially causing respiratory distress, neurological impairment, and increased risks of specific cancers depending on the precise compound mixture and exposure duration.

Under the National Priorities List, the Agway/Kress Property remains in an active operational phase, meaning the EPA is currently conducting long-term cleanup and monitoring protocols to contain further environmental degradation. Given the dense concentration of active remediation sites, residents must adopt immediate preventative measures to mitigate exposure risks. Individuals relying on private wells must commission comprehensive annual groundwater testing through certified independent laboratories to detect trace industrial chemicals. Homeowners should immediately install whole-house water filtration systems capable of eliminating volatile organics and heavy metals. Property owners must also secure professional sub-slab vapor intrusion assessments to ensure subsurface toxic gases are not accumulating within enclosed basement spaces.
