ClearExploring 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.
Severe microplastic pollution risks in urban freshwater system post-landfill fire: A case study from Brahmapuram, India
Researchers documented a dramatic increase in microplastic pollution in freshwater systems near the Brahmapuram landfill in Kochi, India, following a major landfill fire. Post-fire surface water samples showed microplastic concentrations nearly doubling compared to pre-fire levels. The study demonstrates that landfill fires can rapidly release large quantities of microplastics into surrounding urban waterways, creating acute pollution events.
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.
Characterization of microplastics in soil, leachate and groundwater at a municipal landfill in Rayong Province, Thailand
Microplastics were found in soil, leachate, and groundwater at a municipal landfill in Rayong Province, Thailand, with concentrations and polymer types varying by sample matrix and proximity to the landfill, raising concerns about landfill as a source of MP groundwater contamination.
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.
Sources, health risks, environmental implications, and management strategies of microplastics with a focus on landfill leachate

Microplastics in landfill leachate - characteristics and common methods of identification
This review characterized microplastics in landfill leachate, covering their physical and chemical properties and the common analytical methods used for identification. Around 40% of global plastic waste ends up in landfills, making leachate a significant but understudied pathway for microplastic release into groundwater and surrounding environments.
Risk assessment of microplastics contamination in soil and leachate from different ages of landfill
Researchers assessed microplastic contamination in soils and leachate collection ponds at a landfill site in Thailand, examining how the physical and chemical characteristics of microplastics — including abundance, morphology, size, and polymer type — evolve across landfill sections of different ages. The study found that microplastic properties change significantly with landfill age, highlighting landfills as important sources of environmental microplastic pollution with implications for leachate treatment.
Microplastics in municipal solid waste landfill leachate and their removal in treatment units: A perspective of controlled and uncontrolled landfills
This study measured microplastic contamination in liquid waste (leachate) from two landfill sites in India, finding polyethylene and polypropylene as the most common types. Controlled landfills with treatment systems removed some microplastics, but significant amounts still escaped into the surrounding environment. The findings highlight landfills as an overlooked source of microplastic pollution that can contaminate nearby soil, rivers, and groundwater used by communities.

Researchers determined microplastic abundance in dug wells within 1 km of the Tamangapa Landfill in Makassar, Indonesia, finding that fibers (72%) and fragments (28%) were the dominant forms, with microplastic sizes ranging from 0.069 mm to 4.459 mm, suggesting landfill proximity as a contamination source.
Microplastic 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.
Spatiotemporal distribution and ecological hazards of microplastic pollution in soil water resources around a wastewater treatment plant and municipal solid waste site
Researchers mapped the spatial and seasonal distribution of microplastics in soil, water, and sediment near a wastewater treatment plant and municipal landfill in northern India. They found elevated microplastic concentrations in leachate and areas immediately surrounding both facilities, with seasonal variations in contamination levels. The study highlights that both wastewater treatment plants and solid waste sites serve as significant local sources of microplastic pollution to surrounding environments.
Investigation of Microplastics and Microplastic Communities in Three Waterbody Basin Soils of Thiruvananthapuram District, Kerala, India
A survey of three waterbody basin soils in Kerala, India found microplastics in all samples, with particle shapes including flakes, fragments, filaments, and fibers ranging from 0.3 to 4.7 mm. The polymers identified — HDPE, LDPE, PP, PET, PS, and nylon — reflect common plastic waste, with the highest concentrations near urban areas, indicating land-based human activity as the primary contamination source.
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.

Identification of Microplastics Using µ-Raman Spectroscopy in Surface and Groundwater Bodies of SE Attica, Greece
Scientists found microplastics in both surface water and groundwater samples across southeastern Greece, with shallow wells containing far more particles than deeper sources. Four common plastic types were identified: polyethylene, polypropylene, polystyrene, and PET. The detection of microplastics even in deeper groundwater suggests these particles can migrate through soil layers, raising concerns about contamination of drinking water sources.
