ClearSpatial 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.
Microplastic pollution unveiled: the consequences of small unregulated dumping in villages, spanning from soil to water
Researchers studied microplastic pollution at unregulated village dumpsites in India and found widespread contamination in the surrounding soil and water. The study identified a variety of plastic types and shapes, including fibers, fragments, and films, moving from dump sites into nearby aquatic environments. This matters because informal waste disposal in rural areas is a largely overlooked source of microplastic pollution that can affect local water quality.
Waste dumps as microplastic hotspots: a comparative investigation at urban, suburban, and rural areas of Eastern India and associated risk assessment
This study measured microplastic contamination at waste dump sites across urban, suburban, and rural areas in Eastern India and found concentrations as high as 3,457 particles per kilogram. High-hazard plastics like PVC and polyurethane were present, and riverside dumps showed especially high ecological risk scores. The findings suggest that waste dumps are significant sources of microplastic pollution that can contaminate nearby water and soil used by local communities.
Exploring the abundance of microplastics in Indian landfill leachate: An analytical study
Researchers analyzed microplastics in leachate from two major landfills in India and found concentrations of 1,473 to 2,067 particles per liter, with most particles smaller than 100 micrometers. Polyethylene terephthalate, polypropylene, cellulose acetate, and PVC were the most common plastic types identified. Since landfill leachate can seep into groundwater and nearby water bodies, these findings raise concerns about microplastic contamination of drinking water sources near dump sites.

Researchers measured microplastic contamination in leachate (liquid that drains through waste) and soil at an open dumpsite in Thailand, finding high levels of plastic particles along with toxic heavy metals and harmful chemicals like BPA and phthalates. The results show that open dumpsites are major sources of microplastic and chemical contamination that can enter groundwater and food chains.
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.
Implications of solid waste dumps on the microplastic abundance in groundwater in Kollam, India
Groundwater wells near waste dump sites in Kollam, India contained an average of 12 microplastic particles per liter, with fibers being the most common type. Larger dump sites were associated with higher microplastic levels, and the groundwater near heavy dumping sites was also more acidic, suggesting leachate from waste dumps is contaminating the water supply. This is a direct human health concern because many communities depend on well water for drinking, and microplastics in groundwater are difficult to remove.

This review documents evidence for major microplastic health concerns in India, covering contamination of food, water, and air in urban and rural contexts, and calling for nationally coordinated monitoring and regulatory responses to plastic pollution.
Biofilm-associated microplastic contamination in rural soil and water: emerging hazards to ecosystems
Researchers found significant microplastic contamination in soil and water near rural dumpsites in areas with poor waste management, with polystyrene and PET being the most common plastic types. The microplastic surfaces were colonized by bacteria that showed resistance to the antibiotic streptomycin, highlighting a dual threat of chemical pollution and drug resistance. These findings show that unregulated rural waste disposal creates hotspots where microplastics and antibiotic-resistant bacteria can enter local water supplies.
Microplastic pollution in terrestrial environment: Identification, characterization, and risk assessment in Indore, Central India
Researchers measured microplastic contamination in soil from agricultural and recreational areas in Indore, India. Recreational sites had about six times more microplastic particles than farmland, with most particles made of common plastics like PET and polypropylene. While the ecological risk was rated low for now, the long-term buildup of these particles in soil could eventually pose threats to crops and the food chain.
