Overcoming Slope Failures at Closed Landfill | EARTHRES Engineering

Project Background

A closed landfill operator faced significant safety concerns due to multiple shallow slope failures along an exterior slope near a main access roadway. EARTHRES was engaged to perform a detailed investigation and develop an economical remediation plan. The comprehensive approach taken by EARTHRES resulted in a six-step progressive remediation recommendation process, ensuring long-term slope stability and safety while managing costs effectively. 

The Results

The solution provided by EARTHRES resulted in significant safety improvements and operational efficiencies for the client. Key outcomes included: 

• Improved Safety: The progressive remediation plan ensured that slope stability was continuously monitored and addressed, reducing the risk of further slope failures and enhancing personnel safety. 
• Cost-Effective Landfill Solutions: The six-step remediation process allowed the client to implement remedial efforts as needed, optimizing costs and resources over time. 
• Enhanced Understanding of Slope Conditions: The sensitivity analyses and iterative modeling provided a detailed understanding of the factors contributing to slope failures, enabling more effective long-term management. 

The collaboration between the landfill operator and EARTHRES resulted in a robust and economical solution to address the slope failures at the closed landfill site. EARTHRES's expertise and methodical approach ensured that the remediation efforts were effective, safe, and cost-efficient. 

Looking ahead, the client can continue to rely on EARTHRES for ongoing monitoring and additional support as needed. The partnership exemplifies how engineering expertise and a tailored approach can address complex environmental challenges effectively.
