ClearMicroplastic distribution in monitoring well water in the final landfill area Putri Cempo Surakarta Indonesia
Researchers sampled groundwater from seven monitoring wells around a landfill in Surakarta, Indonesia, finding microplastic concentrations ranging from 320 to 1,960 particles per liter. Polystyrene, polycarbonate, and polypropylene fragments dominated the samples, confirming that landfills are a significant source of microplastic contamination in groundwater that communities depend on for drinking water.
The occurrence of microplastics in the surface water of several urban lakes in the Megacity of Jakarta
Six urban lakes in the Jakarta metropolitan area were all found to contain microplastics in their surface water, with the most downstream lakes closest to Jakarta Bay showing the heaviest contamination. The study highlights how plastic waste flowing through populated urban watersheds accumulates in lakes before eventually reaching the ocean. Dense urban areas with poor waste management are key hotspots for freshwater microplastic pollution.

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.
Distribution and Abundance of Microplastics in Underground Rivers in the South Malang Karst Area: First Evidence in Indonesia
Researchers documented microplastic contamination in underground rivers within a karst limestone region of South Malang, Indonesia, providing the first evidence of such pollution in the country's groundwater systems. They detected microplastics in all water samples, with fibers being the dominant type. The findings challenge the assumption that karst rock formations act as natural filters, suggesting that surface plastic pollution can penetrate into underground water sources.
The contribution of estuaries to the abundance of microplastics in Jakarta Bay, Indonesia
Researchers found that rivers draining into Jakarta Bay are a major source of microplastics, with polyethylene fragments in the 300-500 micrometer size range dominating, and that spatial variation in abundance across nine estuaries reflects differences in local land use and waste management.
Mapping mismanaged plastic waste in Indonesia: subdistrict-level analysis through material flow from sources to the environment
Researchers found that Indonesia produces over 9 million tons of plastic waste each year, with more than 1 million tons ending up directly in rivers, drains, and illegally dumped on land. This mismanaged plastic waste breaks down into tiny particles called microplastics that can contaminate drinking water and food sources, potentially affecting human health. The study helps identify pollution hotspots where better waste management could reduce plastic entering the environment and our bodies.
Analysis of Microplastic Content in Surface Water of the Gajah Mungkur Reservoir in Indonesia
Researchers analyzed surface water from Indonesia's Gajah Mungkur Reservoir, a drinking water source, and found microplastics at every sampling location, with concentrations ranging from 340 to 820 particles per cubic meter. The dominant shapes were filaments and fibers, and the plastics identified included polypropylene and polystyrene. The highest contamination was found at an upstream river inlet, suggesting that rivers are a key delivery route for microplastics into the reservoir. The findings raise concerns about microplastic exposure through drinking water drawn from Indonesian surface water sources.
Analisis Kandungan Mikroplastik pada Sedimen di Perairan Semarang, Jawa Tengah
Researchers analyzed microplastic contamination in sediments from Semarang waters in Central Java, Indonesia, documenting the types, abundance, and distribution of microplastics across multiple sampling campaigns linked to the city's high population density and waste generation.
Occurrence of Microplastic in surface water of Jatiluhur Reservoir
Researchers investigated microplastic occurrence in the surface water of Jatiluhur Reservoir in Indonesia and found contamination present, driven by inflow from the heavily polluted Citarum River watershed.

Researchers assessed microplastic pollution in the surface water of the Kranji River Basin in Purwokerto, Indonesia, a densely populated urban area, characterising particle abundance, morphology, colour, and polymer type. The study documented widespread microplastic contamination and identified key sources associated with urban population density, waste management practices, and proximity to human settlements.
Existence of Microplastics in Indonesia’s Surface Water: A Review
This review summarizes evidence of microplastic contamination in surface waters across Indonesia, finding widespread pollution in rivers, lakes, and coastal areas. The study underscores the urgency of improved plastic waste management in a country with one of the world's largest contributions to ocean plastic pollution.
Analysis of microplastics in spring water
Researchers sampled six natural springs in Batu City, Indonesia, and detected microplastics in all of them at concentrations of 208–354 particles per cubic meter, even though the water otherwise met drinking water quality standards. The most common plastic types found were nylon, LDPE, PET, and PVC, suggesting that microplastic contamination reaches even groundwater-fed spring sources.
Microplastics in Landfill Environments: Distribution, Characteristics, and Risks from Gampong Jawa, Indonesia
Researchers examined microplastic distribution across soil, leachate, river water, and well water surrounding a landfill in Gampong Jawa, Indonesia. They found alarmingly high concentrations in well water (up to 979 particles per liter) and soil (over 23,000 particles per kilogram), with fragments, fibers, and films being the most common types. The study demonstrates that landfills are significant sources of microplastic contamination that can spread to surrounding communities through water and soil pathways.

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.
Influencing factors of microplastic generation and microplastic contamination in urban freshwater
This study analyzed microplastic contamination in urban freshwater across cities worldwide and identified mismanaged plastic waste and untreated wastewater as the strongest predictors of contamination levels. Smaller microplastic fragments were most closely linked to improper waste disposal, while larger fragments correlated with untreated wastewater discharge. The findings suggest that improving waste management and wastewater treatment in cities could significantly reduce the microplastics entering drinking water sources.
