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.
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.
Contaminación por microplásticos en el acuífero kárstico de la península de Yucatán
Researchers sampled water from cenotes and wells throughout the Yucatan karst aquifer and identified microplastic particles in every groundwater sample, with fibers comprising 94% of particles and concentrations ranging from 10 to 936 particles per liter, establishing that this primary regional drinking water source is universally contaminated with microplastics.
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.
Drinking plastic: a study of microplastic concentrations in drinking water from rural and urban sources in Mali, Africa
Researchers measured microplastic concentrations in drinking water from rural and urban sources in Mali, Africa, finding microplastics in all samples and identifying higher concentrations in urban supplies, with implications for human health in a region with limited water treatment infrastructure.
Microplastics contamination in groundwater of a drinking-water source area, northern China
Researchers investigated microplastic contamination in shallow groundwater from a major drinking-water source area in northern China. The study found microplastics present in groundwater samples, with their abundance, morphology, and chemical composition varying across the study area and correlating with nearby human activities.
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.
Emerging contaminants in rural water: microplastic pollution and its association with agricultural, livestock, and industrial activities in Ecuador
Researchers surveyed 169 samples from 29 rural drinking water systems in southern Ecuador, finding microplastics in 61.5% of samples, with PET as the most frequent polymer and contamination levels correlating with proximity to agricultural, livestock, and industrial activities.
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.
Spatial distribution of microplastic concentration around landfill sites and its potential risk on groundwater
Researchers found microplastic contamination in groundwater near two municipal waste dump sites in South India, with levels ranging from 2 to 80 particles per liter. Nylon was the most common type found, making up 70% of particles, and the contamination was traced back to degrading buried plastic waste. This is concerning because many communities rely on groundwater for drinking, and these findings show landfills can be a direct source of microplastics in drinking water.

Researchers investigated microplastic pollution in groundwater across three land use types in southeastern Hungary, providing data on the rate and distribution of microplastic contamination in a freshwater resource that has received far less study than surface water bodies.
Global distribution, drivers, and potential hazards of microplastics in groundwater: A review
This review maps the global distribution of microplastics in groundwater and finds that contamination is widespread, with fiber-shaped particles and polyethylene being the most common types detected. The study highlights that climate change and local geology play underappreciated roles in how microplastics move through soil into groundwater, which is a drinking water source for billions of people worldwide.
Microplastic accumulation in groundwater: Data-scaled insights and future research
This data-driven review of nearly 400 groundwater samples worldwide found that microplastics are present in both shallow and deep groundwater, with open groundwater sources showing higher contamination than enclosed aquifers. The findings are relevant to human health because groundwater supplies drinking water for billions of people, and the study identifies key gaps in our understanding of how microplastics accumulate underground.
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.
