Sources of Lead Contamination at or near Superfund Sites

Completed

The Superfund program of the US Environmental Protection Agency was created in the 1980s to address human-health and environmental risks posed by abandoned or uncontrolled hazardous-waste sites. This report examines the extent to which various sources contribute to environmental lead contamination at Superfund sites that are near lead-mining areas and focuses on sources that contribute to lead contamination at sites near the Southeast Missouri Lead Mining District. It also recommends potential improvements in approaches used for assessing sources of lead contamination at or near Superfund sites.

Description

An ad hoc committee will examine the extent to which various sources contribute to environmental lead concentrations in areas at or near Superfund sites that are situated within or adjacent to lead-mining areas. The committee will consider whether sources, such as naturally occurring lead, lead-based paint, and the consumer use of products that contain lead, are significant contributors to environmental contamination problems identified through the Superfund site assessment process. In addition, it will consider the extent to which the chemical form of lead in the environmental media can be attributed to particular kinds of sources.


The committee will focus primarily on sources contributing to environmental lead concentrations at or near Superfund sites within or adjacent to the Southeast Missouri Lead Mining District. It also will consider several Superfund sites within or adjacent to other lead mining areas in the United States.

The committee will recommend potential improvements in approaches used for assessing sources of lead contamination at or near Superfund sites, without recommending changes to the clean-up requirements or remediation activities at any designated site. The committee also will identify important research needs.
