What is a key concern during the site preparation regarding landfills?

A key concern during site preparation regarding landfills is that unrecorded landfills need immediate attention. This is important because unrecorded landfills can pose significant environmental hazards, including potential contamination of soil and groundwater. If these sites have not been formally documented, there may be a lack of awareness or oversight regarding the risks they present. Addressing unrecorded landfills before site preparation ensures compliance with safety regulations and environmental standards. It also helps in preventing unforeseen complications during construction activities, which can lead to health risks and costly remediation efforts. Recognizing the presence of all landfills, especially those not documented, is essential for responsible planning and development. Proper assessment and mitigation strategies should be established to manage these potential hazards effectively.
