ClearContamination, 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.
First evidence of microplastics and their characterization in bottled drinking water from a developing country
Scientists in a developing country analyzed 10 brands of bottled drinking water and found microplastics in all samples, with concentrations varying by brand. The most common particles were polyethylene and polypropylene fragments and fibers, likely originating from the plastic bottle caps and packaging. This study adds to evidence that bottled water is a significant source of daily microplastic intake for people worldwide.

The study highlights the need for standardized testing methods and regulatory limits to protect public health from microplastic exposure through drinking water.
Microplastics in freshwater lakes: A case study from Southern India
Researchers assessed microplastic contamination in Vellayani Lake, a major drinking water source in southern India, and found particles present across all sampling sites and seasons. Fibers were the most common shape, with polyethylene and polypropylene as the dominant polymer types, likely originating from domestic wastewater and fishing activities. The study highlights the need for monitoring microplastic pollution in freshwater lakes that serve as critical drinking water supplies.
Presence and Quantification of Microplastic in Urban Tap-Water
Tap water samples from Brasília, Brazil were found to contain microplastic contamination, with fibers being the most common type detected across both residential zones tested. The study adds to growing evidence that people may be regularly ingesting microplastics through municipal drinking water.
Presence of microplastics in drinking water from different freshwater sources in Flanders (Belgium), an urbanized region in Europe
Researchers analyzed drinking water from nine treatment plants and nine household taps across Flanders, Belgium, and found low but measurable levels of microplastics (averaging 0.01–0.02 particles per liter), with polypropylene and PET as the most common types. When extrapolating to include smaller particles not detectable by standard methods, estimated exposure rises to roughly 5–6 particles per liter, highlighting gaps in current detection approaches.
Study of Microplastic Concentrations at the Drinking Water Depot in Sumbersari Village, Jember Regency
Researchers measured microplastic contamination in 12 refillable drinking water depots in Sumbersari, Indonesia, finding an average concentration of 7.1 particles per liter, mostly fibers and fragments. Consumers were estimated to ingest between 5.61 and 15.98 microplastic particles per liter per day.
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.
A Review of Microplastics in Freshwater Environments: Locations, Methods, and Pollution Loads
This review chapter summarizes global research on microplastics in freshwater environments, covering detection locations, sampling methods, and pollution levels. Because many freshwater bodies serve as drinking water sources, understanding where microplastics occur and in what quantities is critical for assessing risks to human health.
Microplastic accumulation, morpho-polymer characterization, and dietary exposure in urban tap water of a developing nation
Researchers analyzed tap water from four major cities in Bangladesh and found microplastics in every sample, with an average of about 35 particles per liter, higher than most other countries studied. The vast majority were tiny fibers less than 0.5 mm, primarily made of polyethylene. The estimated daily intake of about 2.65 microplastic particles per person through tap water alone highlights how people in developing nations may face disproportionate microplastic exposure through their drinking water.
Microplastics in Malaysian bottled water brands: Occurrence and potential human exposure
Researchers tested eight major bottled water brands sold in Malaysia and found microplastic particles in all of them, with concentrations varying significantly between brands. The most common types were fragments and fibers made of polyethylene and polypropylene. The study estimates daily microplastic intake from bottled water consumption and highlights the need for quality standards addressing microplastic contamination in drinking water.
