Current status of researches on microplastics in groundwater and perspectives
This review examines the current status of microplastic research in groundwater systems internationally, identifying that despite growing attention to microplastics in surface and marine waters, groundwater investigations remain sparse both in South Korea and globally. Researchers diagnosed gaps in monitoring methodology and management frameworks, proposing directions for more effective groundwater microplastic assessment.
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 contamination and characteristics of agricultural groundwater in Haean Basin of Korea
Researchers investigated microplastic contamination in agricultural groundwater in Korea's Haean Basin, an area without nearby landfills or obvious pollution sources. They found microplastics present in groundwater samples, suggesting that agricultural activities alone can introduce these particles into underground water supplies. The study raises concerns about drinking water quality in farming regions and highlights the need for more research on how microplastics move through soil into groundwater.

Emerging Concerns about Microplastic Pollution on Groundwater in South Korea
This editorial raises concerns about microplastic contamination in groundwater in South Korea, framing modern times as the "Plastic Age" due to the pervasive presence of synthetic polymers in all environmental compartments including underground water sources.
Microplastic Contamination in Groundwater Aquifers along the Ganga River Basin: A Comprehensive study from Devprayag to Gangasagar, India
Researchers investigated microplastic contamination in groundwater aquifers along the Ganga River basin from Devprayag to Gangasagar, India, detecting microplastics at all sampling sites and linking contamination levels to population density and river proximity.
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.
Microplastics Pollution in the Groundwater of Three Land Use Types, Southeastern Hungary
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.
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.
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.
Effects of groundwater sample volume on identified microplastics in groundwater of an agricultural area in Korea
Scientists tested how much groundwater needs to be sampled to get an accurate picture of microplastic contamination in agricultural areas of South Korea. They found that sampling at least 100 liters of groundwater was necessary to reliably detect microplastics, and smaller samples often missed particles entirely. The study highlights that inconsistent sampling methods may be leading to underestimates of groundwater microplastic pollution.

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.

Researchers investigated microplastic contamination in groundwater on Jeju Island, a volcanic island in South Korea, sampling 21 groundwater wells and springs. The study, reported as the first to identify microplastics in groundwater from a volcanic island, found contamination present across sampling sites, raising concerns about microplastic infiltration into subsurface water resources.
