Cambridge, Massachusetts, ZIP code 02238, currently carries a critical environmental hazard designation due to extensive localized industrial contamination. Within a ten-mile radius, twenty-one federal cleanup sites exist, including exactly ten within just five miles. The Agway/Kress Property sits approximately 1.9 miles from the center of this area and remains an active Environmental Protection Agency National Priorities List site. The primary threats stem from unspecified hazardous substances associated with legacy industrial activities. While the exact chemical composition remains unclassified, unspecified hazardous substances typically include volatile organic compounds, heavy metals, or industrial solvents. These compounds pose severe exposure risks, potentially causing respiratory irritation, neurological disruption, and elevated long-term risks of chronic diseases when ingested through groundwater or inhaled via soil vapor intrusion.

The Agway/Kress Property, along with close neighboring sites like Shaffer Landfill and Watertown Bemis Dump, holds an active status on the National Priorities List. This indicates that long-term remedial investigation, risk assessment, or active site cleanup operations are currently underway, meaning the environmental threat is recognized but not yet fully mitigated by federal authorities.

Given the high concentration of active remediation zones, residents must take immediate precautionary measures. Households should install certified reverse osmosis water filtration systems to eliminate potential heavy metal or solvent ingestion from tap water. Property owners should arrange for independent vapor intrusion testing in residential basements to detect off-gassing from subsurface soil contamination. Residents should avoid unauthorized access to nearby industrial parcels and strictly utilize raised garden beds with imported soil for all local agricultural activities.
