ClearFirst insight into microplastic groundwater pollution in Latin America: the case of a coastal aquifer in Northwest Mexico
Researchers conducted the first investigation of microplastic pollution in groundwater in Latin America, analyzing six capped boreholes in a coastal aquifer in northwest Mexico for microplastic abundance, concentration, and characteristics. The study detected microplastics in groundwater samples, establishing baseline contamination data for this understudied environmental compartment and raising concerns about drinking water quality in the region.
First insight into microplastic groundwater pollution in Latin America: the case of a coastal aquifer in Northwest Mexico
This is the first study to investigate microplastic contamination in groundwater in Latin America, examining a coastal aquifer in Northwest Mexico. Researchers found microplastics at all six sampled locations and at multiple depths, confirming that groundwater is not immune to this type of pollution. Since millions of people depend on groundwater for drinking water, these findings raise important questions about microplastic exposure through water supplies.

Researchers detected microplastics in drinking water from ten rural wells in two Mexican communities, finding diverse polymer types and morphologies at concentrations that suggest widespread groundwater MP contamination even in areas distant from major urban pollution sources.
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.
Contamination, morphological and chemical characterization, and hazard risk analyses of microplastics in drinking water sourced from groundwater in a developing nation
Researchers analyzed groundwater from six coastal districts in a developing nation and found widespread microplastic contamination, with fibers and fragments of polyethylene and polypropylene being the most common types. Since groundwater is the primary drinking water source in many developing countries, this contamination represents a direct pathway for microplastic ingestion by millions of people.
Occurrence of microplastics in a coastal aquifer in Northwest Mexico
Researchers analyzed 18 groundwater samples from six boreholes at three depths in the Laguna Agua Grande coastal aquifer in Northwest Mexico, finding 221 microplastic particles at concentrations averaging 12.3 particles/L. Four polymers were identified by FTIR, with isotactic polypropylene dominating at 64%, and agriculture activities and septic tank outflows identified as likely sources with three proposed transport pathways into the aquifer.
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.
Distribution and transport of microplastics in groundwater (Shiraz aquifer, southwest Iran)
Researchers investigated microplastic contamination in groundwater from an alluvial aquifer in a semi-arid region of Iran. They identified microplastics in all sampled wells, with fibers and fragments being the most common shapes and polyethylene the dominant polymer type. The study demonstrates that groundwater, an important source of drinking water, is not immune to microplastic contamination and calls for more research on transport mechanisms in subsurface environments.
Microplastics in groundwater: a global analysis
Researchers conducted a global groundwater sampling study — collecting approximately 300 litres per site from caves, boreholes, monitoring wells, and surface springs worldwide using a standardised filtration protocol — to characterise microplastic contamination in these poorly studied anoxic systems. The study presented first results aimed at closing a major knowledge gap about microplastic transport and fate in global groundwater resources.
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.

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 particles investigation in karst aquifer (Zvenigorod, Russia)
Researchers investigated microplastic particle presence and distribution in a karst aquifer near Zvenigorod, Russia, finding that single-use plastics and inadequate waste management are contributing to groundwater MP contamination even in this relatively protected geological setting.
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.
