Acton, Massachusetts, ZIP code 01720, currently carries a critical environmental hazard designation due to severe proximity to multiple active contamination zones. The area is heavily impacted by an exceptional density of industrial waste facilities, including ten recognized hazard sites within a five-mile radius and twenty-one within ten miles. Notably, the Agway/Kress Property remains an active National Priorities List Superfund location undergoing continuous EPA oversight and remediation. Other immediate threats include the Shaffer Landfill and Watertown Bemis Dump, both located fractions of a mile from residential zones. While the EPA designates the primary contaminants at the Agway/Kress Property as unspecified hazardous substances, typical pollutants from legacy industrial sites include volatile organic compounds and heavy metals. Long-term environmental exposure to these toxic agents can profoundly affect residents, causing chronic respiratory distress, neurological impairment, and elevated cancer risks through vapor intrusion or groundwater consumption.

Because the Agway/Kress Property and surrounding locations retain active federal status, the EPA is executing long-term cleanup phases, encompassing soil excavation and sustained groundwater treatment operations. Until remediation achieves safe thresholds, residents must implement rigorous protective measures to mitigate exposure risks. First, inhabitants relying on private wells must commission independent, certified laboratory testing for heavy metals and volatile organic compounds bi-annually, as municipal testing does not cover private sources. Second, residents should install certified reverse osmosis filtration systems on all potable water taps to intercept migrating subsurface contaminants. Finally, homeowners must seal basement foundations and install active sub-slab depressurization systems to prevent hazardous vapor intrusion from migrating soil gases.
