Lead table.

Last updated Nov. 3, 2017

Lead is a naturally occurring bluish-gray metal found in the earth's crust. Lead can be found in all parts of our environment and has many different uses. Much of it comes from human activities including burning fossil fuels, mining and manufacturing. It is used in the production of batteries, ammunition, metal products (solder and pipes) and devices to shield X-rays. Lead was used for many years in paints and other products found in and around our homes. Lead-based paints were banned for use in housing in 1978. The use of lead as an additive to gasoline was also banned in 1996 in the United States. 

Lead is a highly toxic metal. Lead exposure can affect nearly every system in the body. Children under the age of 6 are especially susceptible to lead poisoning. There are approximately half a million U.S. children ages 1 to 5 with blood lead levels above five micrograms per deciliter (µg/dL), the reference level at which health officials recommend public health actions be initiated. Lead-based paint and lead contaminated dust are the main sources of exposure for lead in children. Lead poisoning is a both preventable and treatable condition.

For most of the late 19th and early 20th centuries, Missouri was the global leader in lead production, and even today some of the largest and most important remaining lead deposits in the world are located in southeast Missouri.  Lead production has played an important role in the economic growth and development of Missouri.  Estimates of the aggregate lead production in Missouri since mining began in the early 18th century, top 17 million tons, at a value of nearly $5 billion. 

The Missouri Department of Natural Resources and other state and federal agencies are working to prevent or reduce lead releases to the environment. This website contains information about lead mining in Missouri, state and federal regulation of lead sites, Missouri's strategy for dealing with impacts from lead contamination and links to additional information about lead.

Salem Plateau Groundwater Province - The Salem Plateau groundwater province is also host to many of Missouri’s largest springs. All of the the state's first magnitude springs are in the Salem Plateau groundwater province. Although this region contains abundant groundwater resources, the geology in some areas makes groundwater particularly prone to contamination.
