Landfill, groundwater, groundwater pollution, GIS, leachateAbstract
This Scopus-based bibliometric review maps research on landfill–groundwater interactions (2000–2024) to identify dominant themes, underexplored topics and methodological gaps that limit evidence-based groundwater protection near landfills. Using the query “landfill” AND “groundwater”, we extracted 601 records and analysed trends with Biblioshiny, MapChart and Excel. The analysis highlights the countries, institutions and keywords on which the literature concentrates. It shows a shift from standalone laboratory approaches toward integrated frameworks that combine hydrogeological monitoring, laboratory chemistry and GIS/remote-sensing support. These results provide a roadmap for future studies and for decision-makers by prioritising interdisciplinary research needs, including leachate–aquifer pathways, medium-sized cities and long-term monitoring strategies.
