How is soil abatement typically achieved?

Soil abatement is typically achieved through methods that effectively eliminate or contain contaminants that pose risks to health and the environment. The method of removal, replacement, or paving with asphalt is a comprehensive approach that ensures that the contaminated soil is either completely removed and replaced with clean soil or is effectively contained to prevent exposure. This method addresses both immediate and long-term risks associated with contaminated soil, making it a standard practice in environmental remediation.

The option of painting over contaminated soil does not address the underlying problem of contaminants within the soil. Likewise, simply covering the area with a tarp provides only a temporary solution, as it does not remove or neutralize the contaminants present. Sanding down the surface area is also ineffective since it does not target the soil contamination directly and can potentially release harmful particles into the environment. Thus, the chosen method of removal, replacement, or paving with asphalt stands out as the most effective solution for soil abatement.
