The 04103 zip code area of Portland, Maine, currently holds a critical environmental hazard designation due to significant industrial contamination. The region is impacted by fifteen monitored environmental sites within a ten mile radius, including ten facilities within just five miles. The most prominent active Superfund location is Accent Dry Cleaners, situated approximately three and a half miles away. Several other active monitoring sites, including Burt Company, ME ARNG OMS 1, Wash Tub II, and Colonial Cleaners, operate within two miles. Accent Dry Cleaners remains on the active National Priorities List, indicating that the Environmental Protection Agency is currently executing long term remediation, monitoring, and investigation protocols to control ongoing pollution.

The primary pollutants associated with these facilities are documented as unspecified hazardous substances, which typically include legacy commercial dry cleaning and manufacturing solvents. When these toxic compounds migrate into local soil aquifers and groundwater sources, prolonged exposure causes severe health complications for residents. Documented health impacts from these industrial chemicals include neurological damage, liver toxicity, respiratory distress, and an elevated risk of various cancers. Because groundwater contamination and soil vapor intrusion present the most direct exposure pathways, residents must implement specific, immediate safety measures. Households utilizing private wells must test their water supply bi-annually for volatile organic compounds and install certified reverse osmosis water filtration systems. Residents living in ground-level or basement apartments should install commercial-grade carbon air purifiers to mitigate potential soil vapor intrusion. Finally, residents should avoid planting edible gardens directly in native ground, utilizing raised beds with imported soil instead.
