ClearMicroplastic pollution in Slovenia's groundwater.
Researchers investigated microplastic pollution in Slovenia's groundwater, documenting contamination pathways from urban, agricultural, and industrial activities and assessing the extent to which synthetic particles have infiltrated subsurface drinking water sources in a country where groundwater supplies approximately 98% of drinking water.
Microplastics pollution in groundwater: Case study - Slovenia
Researchers investigated microplastic pollution in Slovenian groundwater, which supplies drinking water to 98% of the population, characterizing MP occurrence, transport, and risk across multiple aquifer systems affected by urban, industrial, and agricultural activities.
Microplastic pollution in Slovenia's groundwater.
Researchers investigated microplastic pollution in Slovenia's groundwater, examining how microplastics from urban, agricultural, and industrial activities enter and distribute through subsurface water systems in a country where groundwater supplies approximately 98% of drinking water.
Contaminants in Urban Stormwater: Barcelona case study
Researchers analyzed contaminants in urban stormwater runoff in Barcelona, examining dissolved organics, metals, nutrients, and microplastics to assess risks to environmental and public health as cities consider stormwater as a potential groundwater recharge source.
Contaminants of emerging concern in the urban aquifers of Barcelona: Do they hamper the use of groundwater?
Researchers compiled data on contaminants of emerging concern — including pharmaceuticals, benzotriazoles, and pesticides — in Barcelona's urban aquifers, finding that several compounds including azithromycin, lamotrigine, and gabapentin pose intermediate to very high health risks, particularly for young children, challenging the viability of this groundwater as a drinking source.
Urban and Groundwater Microplastic Contamination: Sources, Distribution, Impacts, and Remediation Technologies
This review addressed microplastic contamination in urban environments and groundwater systems, covering source pathways from roads and stormwater runoff, distribution through urban catchments, and potential impacts on drinking water aquifers. It highlighted groundwater as an understudied but critical exposure pathway.
Urban Stormwater and Groundwater Quality: Pathways, Risks, and Green Infrastructure Solutions
This review examines how urban stormwater runoff transports microplastics, pharmaceuticals, heavy metals, and pathogens into groundwater, analyzing physicochemical factors affecting pollutant mobility in urban soils and evaluating green infrastructure solutions such as bioswales and permeable pavements.
Contaminación de aguas subterráneas. Algunos ejemplos
This Spanish article reviews major sources of groundwater contamination including agricultural chemicals, industrial waste, and urban effluents, and discusses the difficulty of remediating contaminated aquifers. While focused on traditional pollutants, groundwater contamination pathways are also relevant to emerging concerns about microplastic transport in subsurface environments.
Analysis of Micropollutants in Urban Water Run-off
This study investigates the quality of urban stormwater runoff, focusing on concentrations of micropollutants including heavy metals and microplastics. The research evaluates how runoff from urban surfaces contaminates both groundwater and surface water, and assesses current stormwater management strategies in cities.
Microplastics in groundwater: a global analysis
Researchers conducted a global groundwater sampling study to characterize microplastic contamination in aquifer systems worldwide, investigating transport mechanisms and fate of particles in anoxic subsurface environments where knowledge gaps remain despite extensive research on surface water systems.
Sources and Consequences of Groundwater Contamination
Researchers reviewed sources and health consequences of groundwater contamination across India, China, Pakistan, Turkey, Ethiopia, and Nigeria, summarizing both geogenic pollutants (naturally occurring) and anthropogenic contaminants while identifying key gaps in remediation technology and monitoring capacity.
A comparison of emerging contaminant fingerprinting techniques to assess the impact of human wastewater on karst groundwater quality
This study compared different methods for detecting human wastewater contamination in vulnerable Irish groundwater aquifers, including microplastics as a potential pollution tracer. Karst aquifers are especially vulnerable because direct connections between surface and groundwater make them easy to contaminate.
Assessment of Groundwater Contamination in the Southeastern Coast of Brazil: A Potential Threat to Human Health in Marica Municipality
Researchers assessed groundwater contamination in Marica Municipality along Brazil's southeastern coast, finding that rapid urbanization and inadequate sanitation have led to significant sewage pollution. The study suggests that elevated levels of dissolved organic carbon, nutrients, and bacteria in the aquifers pose a potential threat to public health, since groundwater serves as the primary freshwater source for local residents.
Groundwater quality: global challenges, emerging threats and novel approaches
This review highlights global groundwater quality challenges including emerging contaminants and antimicrobial resistance, emphasizing the need for significantly improved monitoring to identify and mitigate threats from historical and future pollution sources.
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.
Urban stormwater capture for water supply: look out for persistent, mobile and toxic substances
Urban stormwater harvested for water supply was found to contain persistent, mobile, and toxic substances, raising concerns about water quality risks from this increasingly used alternative water source. The study calls for better characterization of stormwater contaminant profiles before use.

Study on purification method of micro-polluted groundwater
This review covers sources and treatment methods for micropollutants in groundwater, including heavy metals, ammonia, nitrates, and organic compounds that infiltrate from surface water. Effective remediation of contaminated groundwater is important because many communities depend on it for drinking water.

Review of Current Issues and Management Strategies of Microplastics in Groundwater Environments
This review synthesizes current knowledge on microplastic contamination in groundwater, identifying it as a substantially understudied environment compared to surface water and marine systems. The authors describe pathways by which microplastics enter aquifers and discuss management strategies for this largely invisible contamination route.
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.

A Global Review of Microplastic Contamination in Groundwater: Empirical Evidence and Latin American Perspectives
Scientists reviewed 129 studies and found that tiny pieces of plastic (called microplastics) are contaminating groundwater around the world, which is concerning because groundwater provides drinking water to billions of people. The research shows we don't know enough about this problem, especially in Latin America where only two studies have actually tested groundwater for plastic contamination. This matters because we need better monitoring and policies to protect our underground water sources from plastic pollution that could affect human health.
