Mapping Global Research Trends in Groundwater Quality (2010–2025): a Bibliometric Perspective

Groundwater quality has garnered increasing attention as climate change intensifies its impact on water resources worldwide. This bibliometric study offers a comprehensive analysis of global research trends in groundwater quality from 2010 to 2025, focusing on the interplay between climate-induced stressors and freshwater systems. Utilizing Scopus-indexed literature and advanced bibliometric tools, the study examines publication patterns, identifies influential authors and institutions, and explores the evolution of key research themes. Through factorial analysis, the research uncovers conceptual structures shaping the field, while co-authorship networks reveal patterns of international collaboration and academic alliances. A thematic map provides insight into the maturity and relevance of research clusters, highlighting areas such as contaminant transport, hydrochemical modeling, and climate-resilient water management. The trend topic analysis pinpoints emerging themes, including microplastic pollution, extreme event-driven contamination, and AI-based groundwater monitoring techniques. Findings reflect a significant increase in interdisciplinary approaches that integrate climate science, environmental engineering, and public health. This study serves not only as a reference for researchers and policymakers but also as a strategic guide for future investigations aimed at mitigating climate-driven impacts on groundwater resources.
