Seasonal dynamics of microbial diversity and functional potential in active sanitary landfill baseliner microbiomes.

ABSTRACT: Sanitary landfilling remains a cost-effective waste management strategy, employing engineered liners and leachate collection systems to mitigate environmental pollution. However, long-term degradation of compacted clay baseliners (CCLs) poses risks to environmental safety and groundwater quality. This study investigated seasonal and habitat-specific microbial communities within CCLs and leachate from the Pulau Burung Sanitary Landfill, Pinang, Malaysia, utilizing 16S rRNA gene amplicon sequencing and functional prediction via PICRUSt2. Triplicate samples were collected from leachate and baseliner layers (0-30 cm depth) during both rainy and dry seasons, alongside assessments of physicochemical properties and permeability. Significant seasonal differences (p < 0.05) were observed in the phy
