Public Health Assessment for Magnolia City Landfill, Magnolia, Columbia County, Arkansas, Region 6. CERCLIS No. ARD980795975.

摘要

Magnolia City Landfill is an active municipal landfill located near Magnolia, Arkansas. Aluminum hydroxide sludge and liquid hazardous wastes, primarily consisting of organics and solvents, are among the different types of waste materials which have been accepted by the landfill since the mid-1950's. Past waste disposal practices included burning liquid waste and placing the residual in a disposal pit, and pouring liquid waste into drums which were later buried. Monitoring has indicated lead and zinc contamination in two residential wells. The source of the contamination has not been determined. Although ingestion or inhalation of contaminants in the ground water from the site would be a public health concern, whether this is occurring or could occur is unknown. Therefore, it is not possible based on the data provided to evaluate the long-term public health threat raised by the site. The Magnolia City Landfill is an indeterminate public health hazard because a risk to human health may exist from possible exposure to hazardous substances at concentrations that may result in adverse human health effects.
