Lead can be found in the soil around homes built before 1978. Homes painted with lead paint on the exterior may leach lead into the soil when the paint is disturbed. In addition, vacant lots may contain lead in the soil, especially if lead-containing materials were used in the once standing property. Cover bare soil with grass or plants, place doormats at each entryway and wipe shoes well.
Other sources of lead in soil are past use of leaded gasoline and industrial sites, such as smelters, batteries and incinerators.
