Summary: Lead is a naturally occurring bluish-gray metal found in small amounts in the earth's crust. Lead can be found in all parts of our environment. Much of it comes from human activities including burning fossil fuels, mining, and manufacturing. Lead has many different uses. It is used in the production of batteries, ammunition, metal products (solder and pipes), and devices to shield X-rays. Because of health concerns, lead from gasoline, paints and ceramic products, caulking, and pipe solder has been dramatically reduced in recent years.

El Dorado Hills, California, is about 30 miles northeast of Sacramento in El Dorado County. Naturally occurring asbestos has been identified in rocks and soil in the vicinity of El Dorado Hills. Sampling conducted by the U.S. Environmental Protection Agency (EPA) in 2004 found that people taking part in typical outdoor recreational activities could breathe in high levels of asbestos relative to when no dust- or soil-disturbing activities take place. Community members asked the Agency for Toxic Substances and Disease Registry (ATSDR) what this finding meant to their health and what they should do to protect their health.
The Omaha Lead site in the city of Omaha, Douglas County, Nebraska has been contaminated with lead from air emissions from lead refining operations and other sources. The site covers about 17,291 acres (about 27 square miles) where approximately 125,880 residents live, including 14,117 children under 7 years of age (based on 2000 Census data). The site includes residential properties, childcare facilities, schools, and other properties, childcare facilities, schools, and other properties. The Omaha Lead site was added to the National Priorities List on April 30, 2003.
The Tar Creek Superfund Site is located in Northeastern Oklahoma (Ottawa County), near the Oklahoma-Kansas state line. The site comprises a 40-square mile area and includes the communities of Picher, Cardin, Hockerville, Quapaw, North Miami, and Commerce. From the early 1900s through the late 1970s, Northeastern Oklahoma was mined extensively for lead and zinc ore. The milling process for these materials produced waste mine tailings, known locally as "chat." Over the years, the mining companies disposed of the chat by collecting it into large aboveground piles, and by dumping it into flotation or tailing ponds.
Between 1995 and 2008, private citizens petitioned ATSDR about health concerns related to chemicals in the city's air, water, and soil. The petitions focused on
- Chemicals released to soil from a former smelter;
- Chemicals released to air, soil, and water from two landfills;
- Chemicals released to air from refineries and petrochemical companies; and,
- Whether high birth-defect rates in the Corpus Christi area were in any way related to activities at area industrial sites, or to releases from those sites.
ATSDR and Texas Department of State Health Services (DSHS) are conducting an extensive review of environmental health concerns raised by the community members in Midlothian, Texas to determine if chemical releases from local industries could or have affected the health of persons and animals in the area.
