The 02739 zip code area of Mattapoisett, Massachusetts, carries a critical environmental hazard designation due to its proximity to active federal remediation zones. There is one major contamination zone within five miles and ten total sites within a ten-mile radius. The most immediate concern stems from the Atlas Tack Corp. facility, located 4.8 miles away. This location is designated as an active site on the EPA National Priorities List, indicating that long-term federal cleanup and containment operations are underway but incomplete. Several other active locations, including the Aerovox Site and New Bedford facilities, sit just beyond the five-mile radius, compounding regional environmental burdens.

Regulatory records list the primary contaminants in this sector as unspecified hazardous substances. Because these industrial byproducts typically migrate through local groundwater aquifers and wind-blown soil particulate, residents face potential secondary exposure pathways. Chronic exposure to such broad-spectrum industrial compounds can compromise respiratory systems, disrupt endocrine functions, and increase long-term neurological risks.

Given the active status of these federal cleanup efforts, residents must adopt immediate mitigation strategies. First, households relying on private wells should commission independent laboratory water testing annually to monitor for migrated heavy metals and volatile organic compounds. Second, residents should install certified high-efficiency particulate air filtration systems in their homes to capture airborne soil dust that may carry residual contaminants from regional sites. Finally, individuals should utilize raised garden beds with imported, clean topsoil for any residential agricultural activities to prevent direct contact with potentially degraded native ground.
