Excerpt from Lead Poisoning in the Smelting and Refining of Lead The last 15 or 20 years have seen great changes in the lead smelting industry of the United States. As transportation has improved, small and poorly equipped smelters which had been built near the deposits of ore have been abandoned and the tendency has been to concentrate the work of smelting and refining in a few large plants, for it has proved cheaper to ship the ore to large centers where labor is abundant, than to do the smelting in the mining districts. This change has resulted in a twofold advantage to the worker. In the first place, as these large plants are usually equipped with the latest and best machinery the amount of handwork required has been materially diminished. In the second place, the conditions under which the employees work have been improved, for large, well-built factories are usually freer from dust and fumes than are those of the old type, and newer methods of manufacture involve economies, such as the saving of poisonous volatile products which used to be allowed to escape into the air. Along with the improvement in equipment, there has been in recent years evidence of a greater interest on the part of the managers in the health and safety of their workmen, and there is probably now no plant in the United States in which some effort is not made to lessen the dangers of lead poisoning as well as to prevent accidents. As a result of these changes in most places where lead smelting is an old industry, as in southeastern Missouri, Pueblo, Denver, Leadville, East Helena, Omaha, and South Chicago, the opinion is general among physicians and townspeople, as well as among the men in the industry, that lead poisoning is far less frequent and less severe than it used to be.

The Superfund program of the US Environmental Protection Agency (EPA) was created in the 1980s to address human-health and environmental risks posed by abandoned or uncontrolled hazardous-waste sites. Identification of Superfund sites and their remediation is an expensive multistep process. As part of this process, EPA attempts to identify parties that are responsible for the contamination and thus financially responsible for remediation. Identification of potentially responsible parties is complicated because Superfund sites can have a long history of use and involve contaminants that can have many sources. Such is often the case for mining sites that involve metal contamination; metals occur naturally in the environment, they can be contaminants in the wastes generated at or released from the sites, and they can be used in consumer products, which can degrade and release the metals back to the environment. 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 recommends potential improvements in approaches used for assessing sources of lead contamination at or near Superfund sites.
