What is one recommended interim control for lead contaminated soil?

Covering lead-contaminated soil with grass or sod is a recommended interim control because it effectively reduces the potential for human exposure to lead dust and soil particles. Grass and sod create a physical barrier that prevents dust from becoming airborne and limits direct contact with the contaminated soil. This approach can help to stabilize the soil, minimize erosion, and provide a safer environment, especially in residential areas where children may play.

In addition to protecting against exposure, planting grass or sod can also improve the aesthetic quality of the area and contribute to the environmental health of the landscape. It is a cost-effective solution that can be implemented relatively quickly compared to more invasive measures, such as excavation. By establishing a vegetative cover, it can also promote biodiversity and environmental recovery in areas affected by lead contamination.
