One major source of lead in soils is leaded paint. It’s estimated that lead paint was used on 75% of houses built before 1978, when it was banned. Chalking, leaching, flaking, weathering, scraping, and sandblasting of leaded paint result in lead deposits in the soil near the base of these houses, creating a "halo" of lead contamination. Although less widespread, airborne lead from industrial sources such as metal shops, burn dumps, or battery recyclers may have contaminated some nearby soil.
The State of California- Department of Toxic Substances Control (DTSC) regulates and enforces hazardous waste laws in California. The State of California-Office of Environmental Health Hazard Assessment (OEHHA) evaluated potential exposures to estimate lead concentrations in soil that would lead to an incremental increase in blood lead.
However, you could still run the risk of exposure! If you want the expert lead inspectors at Guzi-West to analyze the soil and lead potential risk at your home, give us a call today! We want to ensure you and your family stay safe. (888) 351-8189
