Tiverton, Rhode Island (ZIP 02878), carries a critical environmental hazard designation due to an unusually high concentration of active hazardous waste sites. Within a ten-mile radius, twenty-six contaminated sites exist, including six within five miles. The most prominent EPA-regulated location is the Former Mill Complex/109 Howe Street LLC, situated 4.8 miles from the area center. Other proximate threats include the former Firestone Landfill and the Tiverton Town Dump, both located within one mile of local neighborhoods. The primary contaminants across these sites are unspecified hazardous substances typical of historical industrial manufacturing and unregulated municipal waste disposal. Exposure to these uncharacterized chemical mixtures presents severe health risks to the community, potentially affecting respiratory, dermatological, and central neurological systems through subsurface groundwater migration or toxic soil vapor intrusion.

Under federal oversight, the Former Mill Complex/109 Howe Street LLC maintains an active remediation status. This regulatory classification indicates that environmental mitigation efforts remain ongoing, with agencies actively monitoring subterranean contamination plumes and enforcing preliminary site stabilization measures. Because the statutory remedial objectives remain incomplete, community exposure pathways may stay open.

To mitigate personal risk, residents should immediately install certified reverse osmosis water filtration systems in their homes to block potential groundwater contamination. Furthermore, households utilizing private residential wells must contract independent laboratories to test their water supplies annually for heavy metals and volatile organic compounds. Finally, individuals should strictly avoid outdoor recreation near the immediate boundaries of the local landfill sites to prevent direct dermal contact with potentially contaminated surface soil and airborne chemical particulates.
