ClearStudy 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.
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.

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.
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.
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.
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.
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.
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.
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 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.
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.
Hydrogeochemical Characteristics and Environment Quality Assessment of Karst Groundwater in Mengzi Basin of Yunnan Province, China
This paper is not about microplastics; it analyzes the water chemistry and pollution levels in karst groundwater in China's Yunnan Province, finding elevated manganese, nitrogen, and organic matter concentrations.
Ecological differentiation and assembly processes of abundant and rare bacterial subcommunities in karst groundwater
Researchers examined ecological differentiation between abundant and rare bacterial communities in karst groundwater in southwest China, revealing distinct assembly processes and environmental drivers that maintain ecosystem stability in these vulnerable aquifers.
Analysis of hydrochemical characteristics and genesis of water-deficient rivers in China: a case study of the Ciyao River Basin in Shanxi Province
This study analyzed the chemical characteristics and origins of water in the Ciyao River Basin, a water-scarce region in China's Shanxi Province. Researchers collected water samples across wet, normal, and dry seasons and found that the water chemistry was influenced by both natural rock weathering and human activities. The findings provide baseline data for managing water quality in regions where water scarcity makes understanding pollution sources especially critical.
From the Mountain to the Valley: Drivers of Groundwater Prokaryotic Communities along an Alpine River Corridor
Researchers sampled river water and groundwater from 59 sites along a 300 km transect of the Mur River valley in Austria and Slovenia, finding that dispersal limitation drives microbial community assembly at high altitudes while homogeneous selection dominates in lowland aquifers, with land use being a key determinant of groundwater microbiome composition throughout.
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.
