Stow, Massachusetts, zip code 01775, carries a critical environmental hazard designation due to a severe concentration of active contamination zones. Within ten miles of this location, twenty-one regulated facilities require monitoring, including ten within a five-mile radius. Notably, the Agway/Kress Property operates as an active site under Environmental Protection Agency oversight.

The primary threat from the Agway/Kress Property involves unspecified hazardous substances. While the exact chemical composition remains broadly categorized by federal regulators, persistent exposure to industrial hazardous waste generally presents severe health risks. These health impacts frequently include neurological disruption, chronic respiratory illness, and increased cancer rates. Such toxic substances typically migrate through local groundwater aquifers, presenting serious ingestion risks for communities utilizing private wells, or they disperse as volatile organic compounds through soil vapor intrusion into residential basements. The Agway/Kress Property currently holds an active status on the National Priorities List. This regulatory classification dictates that formal remedial investigations and environmental cleanup operations remain incomplete, meaning the area has not yet achieved the federal safety thresholds required for deletion from the hazard registry.

Due to the proximity of multiple active remediation zones, residents must implement specific protective measures. Homeowners utilizing private wells should test their water supply biannually for heavy metals and volatile organic compounds using an independent, certified environmental laboratory. Furthermore, households should install point-of-use activated carbon filtration systems on all potable tap water sources. Finally, property owners should commission soil vapor intrusion testing in basements to detect any toxic gas migration from nearby subterranean contamination plumes.
