ClearRecent Advances in Karstic Hydrogeology, 2nd Edition
This edited volume presents recent advances in karstic hydrogeology, covering groundwater flow and behavior in karst systems characterized by soluble rocks including limestone and dolomite, where chemical dissolution creates unique hydrological pathways relevant to water resource management and contaminant transport.
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.
Hydrological modelling: Insights into hydrological signals and contaminant transport
Researchers modeled how future climate-driven changes in hydrological extremes — including floods and droughts — affect contaminant transport in a heavily polluted Scottish catchment, finding that traditional models calibrated on historical data perform poorly when projecting under novel climatic conditions.

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.

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.
Modeling microplastic transport through porous media: challenges arising from dynamic transport behavior
This perspective article reviews microplastic transport through porous media such as soils and aquifers, identifying the limitations of existing hydrogeological models and proposing research directions for more effectively modelling the dynamic, particle-specific transport behaviour of microplastics in porous environments.
Regulatory role of mobile fine particles in anomalous solute transport in porous media.
Researchers used coupled computational fluid dynamics and discrete element method simulations to investigate how mobile fine particles regulate anomalous solute transport in porous media, finding that particle retention alters local flow fields and creates non-Fickian transport behavior in aquifer systems.
Simulation of Solute and Particle Transport in Fractured Media
Researchers comprehensively analyzed how fracture properties, flow regimes, and particle characteristics govern solute transport, particle dispersion, and attachment mechanisms in fractured media, examining the roles of fracture roughness and microplastic particle properties to inform the design of environmental remediation systems in fractured geological 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.
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.
Floods enhance the abundance and diversity of anthropogenic microparticles (including microplastics and treated cellulose) transported through karst systems
This study examined how flood events affect microplastic transport through karst (limestone cave) water systems. Researchers found that floods dramatically increased both the amount and variety of microplastic particles moving through underground waterways. The findings matter because karst systems supply drinking water to about 25% of the global population, and flood-driven pulses of microplastics could contaminate these water sources.
Understanding the impacts of human wastewater effluent pollution on karst springs using chemical contamination fingerprinting techniques
Researchers used multi-tracer chemical fingerprinting to trace human wastewater contamination into karst spring systems, finding that these highly permeable aquifers rapidly transmit pollutants including pharmaceuticals and potentially microplastics from surface sources to drinking water springs.
Does Microplastic Pollution in the Epikarst Environment Coincide with Rainfall Flushes and Copepod Population Dynamics?
Researchers examined whether microplastic pollution in epikarst environments coincides with rainfall flush events and copepod population dynamics, sampling water from karst springs over time to correlate plastic particle concentrations with hydrological and ecological variables. The study found that rainfall-driven infiltration pulses influenced microplastic transport through the karst system, with potential implications for epikarst invertebrate communities.
A Numerical Study on Impact of Coal Mining Activity and Mine Water Drainage on Flow and Transport Behavior in Groundwater
Not relevant to microplastics — this study models groundwater flow and solute transport around an active coal mine in Xinjiang, China, predicting how stopping mine water drainage could cause high-salinity plumes to threaten regional drinking water sources.
Storage-Release Dynamics of Microplastics during rainfall events in Conduit-Fissure Coupled Karst Aquifers
Researchers used high-frequency monitoring in a karst groundwater system in southern China to track how rainfall events mobilize, transport, and store microplastics through conduit-fissure networks, revealing four distinct hydrological stages that sequentially release pre-deposited and newly infiltrated PET and PE fibers into spring water.

How soil moisture and flow regime drive microplastic transport in the vadose zone: insight from modelling and column experiments
Scientists studied how tiny plastic particles move through soil toward underground water sources that we use for drinking water. They found that plastic particles travel very differently depending on how wet or dry the soil is - sometimes getting trapped, other times moving quickly through the ground. This research helps us better understand how microplastics might contaminate our groundwater supplies, which is important for protecting drinking water quality.
Modeling microplastic transport through porous media: Challenges arising from dynamic transport behavior
This perspective article examines the challenges of modeling how microplastics move through soil and groundwater systems, noting that existing transport models designed for other particles fall short. Microplastic properties change dynamically as they interact with their environment, altering their density, surface chemistry, and movement behavior in ways that are difficult to predict. The study argues that new modeling approaches, potentially using data-driven methods, are needed to accurately predict microplastic transport at meaningful environmental scales.
