What minimum cover is required when burying contaminated filter media?

• A. 4 inches
• B. 6 inches
• C. 8 inches
• D. 10 inches

Answer: (B)

The requirement for a minimum cover of 6 inches when burying contaminated filter media is established to ensure effective containment and management of contaminants. This depth is designed to provide adequate isolation between the contaminated materials and the surface environment, helping to prevent the migration of pollutants into nearby soil and groundwater. A cover of this minimum depth helps to mitigate risks associated with exposure to the contaminants, reducing potential health hazards for individuals and the ecosystem. This 6-inch depth is considered sufficient to allow for proper settling and stabilization of the filter media while also providing a layer of soil that can absorb and filter out contaminants naturally over time. This practice not only protects public health but also safeguards environmental quality by limiting the chances of leachate or surface runoff carrying pollutants away from the site.
