You can perform evaluations to find out how much lead you have in your soil and whether it is a problem. These are usually done by environmental consultants familiar with lead in soils.
- Evaluations must be made on a case-by-case basis.
- Evaluations must be sent to the Hazardous Waste Corrective Action Unit, or the Voluntary Cleanup Program for review and approval.
- The goal is to clean up contamination to a level equal to or less than EPA's action level of 400 parts per million (ppm) total lead in soil.
- Allows for unrestricted use of the affected area.
- Usually achievable since lead is relatively immobile in soil.
- Alternatively, a site-specific soil concentration cleanup level for lead can be calculated by taking into account factors such as the extent of contamination, likely exposure pathways, and current and projected land use.
- Institutional controls, and in some cases engineering controls, may be required to prevent contact with contaminated soil.
- The goal is to clean up contamination to a level equal to or less than EPA's action level of 400 parts per million (ppm) total lead in soil.
