Abstract
View PDFLeachate produced in landfills during waste decomposition is a significant environmental hazard. This paper investigates how leachate alters the index properties of soil, which is commonly used as a barrier or cover layer in landfills. A lab-scale experiment simulating landfill conditions was conducted using a PVC pipe column packed with compacted soil. Leachate was applied daily for 21 days. Pre- and post-exposure testing included shrinkage limit, plastic limit, liquid limit, compaction characteristics, UCS, and specific gravity. The study revealed a consistent reduction in soil strength and plasticity, signaling degradation in its containment capability. These findings highlight the necessity of soil treatment and composite barrier systems for effective long-term waste isolation.
