How much cover soil is required daily during active landfilling?

During active landfilling, it is necessary to cover waste with soil to minimize issues related to odor, pests, and the potential for groundwater contamination. The daily cover serves as a barrier that helps manage these environmental concerns effectively.

A requirement of six inches of cover soil provides an adequate thickness to achieve these objectives. Using this amount of soil helps ensure that any exposed waste is adequately sealed, reducing leachate generation and promoting stability on the landfill surface. This coverage also aids in controlling odors and deterring scavengers or pests from accessing the refuse, which is a crucial consideration for maintaining public health and safety around waste management sites.

In contrast, the other options suggest lesser amounts of cover soil, which may not provide sufficient protection or control over the potential issues associated with exposed waste. Therefore, six inches is considered best practice and is aligned with regulatory recommendations for daily cover in active landfilling operations.
