ClearAnalysis 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.

Identification of Microplastics in the Upper Cimanuk Watershed and Waste Management Analysis in Garut Regency, Indonesia
Researchers assessed microplastic contamination in the Upper Cimanuk Watershed in Garut Regency, Indonesia, examining water samples and local waste management practices. Microplastics were found throughout the watershed, with the highest concentrations linked to areas with greater human activity and inadequate waste management. The study suggests that improving waste collection and disposal in the region could help reduce microplastic inputs to this important river system.

Microplastic Contamination in Urban Groundwater: A Case Study From Jakarta Megacity, Indonesia
Groundwater sampled across 121 locations in Jakarta contained between 28 and 236 microplastic particles per liter, with fragment-shaped pieces dominating and concentrations rising near temporary waste disposal sites. This is significant because millions of people in urban Indonesia still rely on groundwater for drinking, meaning microplastics from poorly managed waste are entering a direct route to human consumption.
