Summary

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 presence of microplastics in the environment is a serious problem, affecting water, soil, and air ecosystems.This study aimed to identify the presence and distribution of microplastics in monitoring well water around the Putri Cempo landfill, Surakarta, Indonesia.Groundwater is a vital source of domestic water in the region but is vulnerable to contamination from landfill leachate.Water samples from seven monitoring wells were treated using wet peroxide oxidation, then analyzed under a light microscope and confirmed with Fourier transform infrared spectroscopy (FTIR).The abundance of microplastics ranged from 320 to 1960 particles/L, with fragments as the dominant type, black as the most frequent color, and polystyrene (PS), polycarbonate (PC), and polypropylene (PP) as the main polymers.These results indicate that landfill-derived plastic waste contributes significantly to groundwater pollution.The findings underline the urgency of routine monitoring and integrated waste management to minimize microplastic exposure through community water supplies.
