What action must be taken with contaminated soil?

When soil is found to be contaminated, it is essential to manage it properly to mitigate environmental risks and comply with regulations. Sending contaminated soil to a DEQ-approved landfill is the appropriate course of action as these landfills have the necessary systems in place to handle such materials safely. This ensures that the contaminants do not pose a risk to the environment or public health.

DEQ-approved landfills are equipped to isolate and manage hazardous waste, which is crucial for preventing leachate and groundwater contamination. They follow strict regulations and guidelines designed to protect the ecosystem, whereas actions like composting or storing the soil indefinitely could lead to further environmental degradation or health hazards. Additionally, leaving the contaminated soil on-site without restrictions poses significant risks, as uncontrolled contaminants can spread and cause wider damage. Therefore, removal to a regulated landfill is the prudent, safe, and legally compliant approach.
