Health Assessment for St. Regis Paper Company National Priorities List (NPL) Site, Cass Lake, Minnesota, Region 5. CERCLIS No. MND057597940

摘要

The St. Regis Paper Company National site is partially located inside the City of Cass Lake, Minnesota. The identified site contaminants are polycyclic aromatic hydrocarbon (PAH) compounds, phenols (specifically pentachlorophenol (PCP), and dioxin compounds. The on-site groundwater and soils for both areas are contaminated with PAH compounds, PCP, and several polychlorinated dibenzo-p-dioxins (dioxins). A surface water body was found to be contaminated with low levels of PAH compounds but not PCP. Municipal wells were found to be contaminated with low levels of PAH compounds. The potential human exposure pathways for groundwater include the ingestion, inhalation, and dermal absorption of PAH compounds, PCP, and dioxins. The maximum levels of PAH compounds and PCP found in on-site soils are likely at levels of health concern. The human exposure pathways associated with the surface water channel are ingestion, inhalation of aerosols, and dermal absorption of PAH compounds. Food chain contamination is a possibility and may result from site contamination of the soil, groundwater and surface water. The site is of potential health concern because of the risk to human health resulting from possible exposure to hazardous substances at concentrations that may result in adverse health effects.
