Lebanon, Maine (ZIP code 04027), currently holds a critical environmental hazard designation due to concentrated industrial contamination. The primary threat stems from the Miltonia Management Inc. (Greene Tannery) Superfund site, located just 3.1 miles from the residential center. The Environmental Protection Agency maintains an active National Priorities List status for this facility, indicating that long-term remedial cleanup and ongoing site monitoring phases are actively underway. Regionally, the local environmental threat is compounded by six total hazardous waste sites located within a ten-mile radius, including the Stenton Trust Mill Drum Site and the International Woolen Company.

The EPA characterizes the primary pollutants at the Miltonia facility as unspecified hazardous substances. Given the site’s historical use as an industrial tannery, these typically include dangerous heavy metals like chromium and lead, alongside volatile organic compounds and industrial solvents. Exposure to these compounds, primarily through undetected groundwater migration or soil vapor intrusion, can severely compromise human health. Chronic ingestion or inhalation may cause respiratory distress, neurological impairment, liver and kidney damage, and elevated risks for certain dermal and systemic cancers.

Because groundwater plumes can rapidly migrate from industrial sites, residents utilizing private wells must immediately schedule comprehensive water testing for heavy metals and volatile organic compounds through a state-certified laboratory. Furthermore, households should install point-of-use reverse osmosis water filtration systems specifically certified to remove industrial chemical runoff. Finally, residents must strictly avoid recreational water contact, local plant foraging, or soil excavation near the tannery perimeter to mitigate exposure or ingestion of residual soil contaminants.
