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.
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.
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.
Microplastic pollution in vulnerable karst environments: case study from the Slovenian classical karst region
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.
Assessment of the groundwater recharge processes of a shallow and deep aquifer system (Maggiore Valley, Northwest Italy): a hydrogeochemical and isotopic approach
Researchers analyzed water chemistry and isotopes across shallow and deep groundwater systems in northwest Italy, tracing how water from distant mountain recharge zones mixes before reaching a heavily used drinking water well field. The study clarifies potential pathways for pollutants to reach drinking water supplies, providing critical information for protecting this major regional water resource.
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.
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.
The Effects of Climate Variation and Anthropogenic Activity on Karst Spring Discharge Based on the Wavelet Coherence Analysis and the Multivariate Statistical
Researchers analyzed climate variation and human activity effects on karst spring discharge using wavelet coherence analysis, finding that anthropogenic factors including land-use changes increasingly influence groundwater dynamics alongside natural climate variability.
Recent 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.
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.
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.
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.
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.
Characteristics of Hydrochemistry and Stable Isotopes in a Karst Region in Samcheok, Republic of Korea
This study monitored water chemistry and stable isotopes in a karst region in South Korea across different seasons and years, finding that land use and seasonal variation strongly influenced groundwater quality. Karst aquifers are vulnerable to contamination from surface runoff, including microplastics from agricultural and urban sources.
The influence of stormwater infiltration on downslope groundwater chemistry
Researchers monitored monthly groundwater quality at a bore network downstream of a stormwater infiltration basin in Victoria, Australia, analysing nutrients, major ions, and heavy metals over an extended field program. They identified three groundwater clusters - shallow fresh water near the basin, deep saline water near the stream, and an intermediate mixed zone - revealing that infiltrated stormwater chemistry is transformed by subsurface interactions with soil, vegetation, and underground infrastructure.
Contaminant Trends in Urban Groundwater: Case Study from Ljubljana (Central Slovenia)
This case study from Ljubljana, Slovenia examined contaminant trends in urban groundwater, finding that without appropriate monitoring and prevention strategies, urban activities can significantly degrade aquifer quality.
Microplastic Contamination in Karst Groundwater Systems
Springs and wells from two karst aquifers in Illinois were found to contain microplastics exclusively as fibers (up to 15.2 particles/L), with their presence correlated with phosphate, chloride, and triclosan, suggesting septic effluent as the source. The study demonstrates that karst groundwater systems used for drinking water are vulnerable to microplastic contamination infiltrating through their open, conduit-dominated architecture.
