ClearStudy on the characteristics of water chemistry evolution in typical alpine karst basins
Researchers analyzed water chemistry evolution in alpine karst groundwater systems, tracing how geological and hydrological processes shape ion concentrations and water quality in these vulnerable freshwater sources.
An Overall Perspective for the Study of Emerging Contaminants in Karst Aquifers
This review examines emerging contaminant threats to karst aquifers, which supply about 25% of global drinking water, highlighting their high vulnerability to rapid surface-to-groundwater transport of microplastics, pharmaceuticals, pesticides, and other pollutants due to the open, fissured nature of carbonate rock systems.
The invisible problem of microplastics and microfibres in karst systems and aquifers: a multidisciplinary approach
This thesis investigates how microplastics and microfibres move through karst (limestone) systems and underground aquifers using a multidisciplinary approach, a concern because karst aquifers supply drinking water to roughly a quarter of the global population and are particularly vulnerable to contamination given their direct hydraulic connections to the surface.
Karst water resources in a changing world: Review of solute transport modelling approaches
This review examined solute transport modeling approaches for karst water resources under changing climate conditions, evaluating how models handle rapid conduit flow, matrix diffusion, and the effects of extreme precipitation events. The authors identify a need for models that better capture the high variability and rapid response characteristics of karst systems under more frequent storm events.
A Review of Heavy Metal Migration and Its Influencing Factors in Karst Groundwater, Northern and Southern China
This review examined the migration behavior of heavy metals in karst groundwater systems in southern and northern China, focusing on how karst geology creates unique pathways and controls on heavy metal transport, speciation, and bioavailability.
Microplastics in karstic systems: a review of sources, transport paths and storage
This repository contains geospatial data and bibliographic records supporting a review of microplastic pollution in karst (limestone cave and sinkhole) systems, mapping where microplastics have been detected across these ecologically important groundwater environments. Karst systems supply drinking water to roughly a quarter of the world's population, making microplastic contamination there a significant but understudied human health concern.
Microplastic particles in karst and alluvial aquifers
Researchers studied microplastic particle occurrence and distribution in karst and alluvial aquifer systems, investigating how these subsurface environments serve as sinks or conduits for plastic pollution. The study contributed data on groundwater microplastic contamination in geologically distinct aquifer types.
Microplastic particles in karst and alluvial aquifers
Researchers investigated the occurrence and characteristics of microplastic particles in both karst and alluvial aquifer systems, examining how plastic particles migrate through these distinct subsurface geological environments. The study addressed a significant knowledge gap regarding groundwater contamination by microplastics in aquifers that differ in their hydrogeological properties and filtration capacity.
Study of the Trends of Chemical–Physical Parameters in Different Karst Aquifers: Some Examples from Italian Alps
Researchers installed data-loggers and conducted multi-year chemical and physical monitoring of karst aquifer springs in the Piedmont region of northwestern Italy to characterize how different hydrogeological conditions influence water quality responses to infiltration events. They found that highly karstified aquifers with small saturated zones showed rapid mineralization decreases during flood events, while well-developed saturated zones exhibited piston flow increases in mineralization.
Colloid (Nano- and Micro-Particle) Transport and Surface Interaction in Groundwater
This book examines the field-scale transport and spatial distribution of colloids in groundwater, covering pathogens, clays, nanomaterials, nanoplastics, and microplastics as examples of nano- and micro-particles whose movement through subsurface systems has significant environmental and public health implications.
Study on the Influence of Mining Activities on the Quality of Deep Karst Groundwater Based on Multivariate Statistical Analysis and Hydrochemical Analysis
This study examined how long-term coal mining activities in China affected deep karst groundwater chemistry, finding significant changes to water quality that threaten safe drinking water supply in mining regions.
Groundwater–Surface Water Interactions: Recent Advances and Interdisciplinary Challenges
This review covers recent advances in understanding groundwater–surface water interactions, including their importance for drinking water security and contaminant transport, and argues for interdisciplinary approaches that combine hydrology, ecology, and geochemistry.
Topical Collection: International Year of Groundwater—managing future societal and environmental challenges
Researchers and hydrogeologists highlight the growing importance of groundwater in the global water cycle and call for better assessment, management, and public communication strategies to meet the UN's water-related Sustainable Development Goals by 2030.
Adherence of Polystyrene Microspheres on Cave Sediment: Implications for Organic Contaminants and Microplastics in Karst Systems
This study found that polystyrene microspheres adhere readily to cave sediment particles in karst aquifer systems, with implications for how microplastics and organic contaminants are transported through karst groundwater. Karst systems may act as pathways for microplastics to reach groundwater supplies used for drinking water.

Researchers sampled karst springs, caves, and other habitats in Slovenia's classical karst region and detected microplastics across multiple sites, including springs used for drinking water, raising concerns about plastic contamination of these ecologically sensitive and hydrologically connected underground environments.
The impact of on-site wastewater effluent on rural karstified aquifers
This conference abstract examines how on-site wastewater treatment systems in rural karst regions can contaminate groundwater used for drinking. While focused on nutrient and pathogen pollution, the study is relevant because these same systems also release microplastics into vulnerable karst aquifers.

Spatial distribution characteristics and migration of microplastics in surface water, groundwater and sediment in karst areas: The case of Yulong River in Guilin, Southwest China
Researchers investigated microplastic distribution in surface water, sediment, and groundwater in the karst landscape of the Yulong River in Guilin, China. They found microplastic pollution across all water compartments, with living areas showing the highest contamination and tourism-related disposable plastics identified as a primary source. The study suggests that microplastics reach groundwater through hydraulic exchange with surface water in karst areas rather than through soil infiltration.
