Abundance and characteristics of microplastics in drinking water treatment plants, distribution systems, water from refill kiosks, tap waters and bottled waters
This review summarizes research on microplastic contamination across the entire drinking water supply chain, from treatment plants to tap water and bottled water. Microplastics were found at every stage, with concentrations varying widely depending on location and treatment methods. The findings highlight that people are regularly consuming microplastics through their drinking water, though more standardized research is needed to fully understand the health implications.
Human exposure to microplastics from urban decentralized pay-to-fetch drinking-water refill kiosks
Researchers analyzed 63 drinking water samples from decentralized pay-to-fetch refill kiosks in Mexico City for microplastic contamination. The study found microplastics present in all samples, raising concerns about human exposure through this widely used urban water distribution system that serves a large population.
Microplastics contamination in water supply system and treatment processes
This systematic review found that microplastics are frequently detected in drinking and bottled water despite current treatment technologies, and that no existing method can completely remove them. Integrating advanced treatment approaches with life-cycle assessment and machine learning is needed to address this pervasive contamination of water supply systems.
Occurrence, characterization, and removal efficiency of microplastics in point-of-use drinking water systems: A case study in Dogonbadan, Iran
Researchers sampled inlet and outlet water from point-of-use drinking water systems in Iran and found that rather than removing microplastics, these systems actually increased average concentrations from 11.66 to 20 MPs/L, with polycarbonate and polypropylene as dominant polymer types.
Free, but not microplastic-free, drinking water from outdoor refill kiosks: A challenge and a wake-up call for urban management
Microplastics were detected in water from all 22 free outdoor drinking water refill kiosks tested in Mexico City parks, with an average concentration of 74 MPs per liter. The presence of MPs in these widely-used free water sources highlights a public health gap in microplastic monitoring and removal standards for urban water distribution infrastructure.
Occurrence and Source of Microplastics Contamination in Drinking Water and Performance of Water Treatment Plants in Removing Microplastics
This review summarizes evidence that microplastics are present in both tap water and bottled water worldwide, with bottled water frequently contaminated by particles shed from the plastic packaging itself. Conventional water treatment plants remove between 40% and 93% of microplastics but cannot eliminate them entirely, meaning treated drinking water still carries measurable plastic loads. The chapter highlights the irony that plastic packaging intended to deliver clean water is itself a major source of microplastic contamination.
A solution for controling microplastics in drinking water
Researchers developed and tested a system for controlling microplastic contamination in drinking water, reporting on removal efficiency at levels relevant to public health. The approach offered effective microplastic reduction from drinking water sources including tap and bottled water.
Impact of Drinking Water Treatment on Removal of Microplastics
Microplastics were measured throughout six drinking water treatment facilities using Raman spectroscopy and found at concentrations ranging widely in source water, with treatment processes achieving substantial but incomplete removal.
Presence of microplastics in drinking water from freshwater sources: the investigation in Changsha, China
Researchers measured microplastic abundance at multiple stages of a drinking water supply chain in Changsha, China — from source freshwater through treatment to household taps — finding that water treatment reduced MP concentrations by more than 85% but tap water still contained an average of 344 particles per liter.

Researchers traced microplastic contamination through the Bedadung River water treatment chain in Indonesia, from intake to consumer taps, at seven sampling points. MPs were present throughout the system, with concentrations declining through treatment stages but not reaching zero, indicating residual MP exposure in treated drinking water.
Microplastics in urban water cycles: Looking for a more scientific approach for sampling and characterization in wastewater and drinking water treatment plants
Researchers monitored microplastics in urban water cycles across three drinking water plants and two wastewater treatment plants using a self-designed large-volume sampler that collected up to 1,000 liters per sample. Raw drinking water and wastewater contained 2 or more microplastic particles per liter, highlighting contamination across the urban water system.

Microplastic removal across ten drinking water treatment facilities and distribution systems
Researchers characterized microplastic removal across ten drinking water treatment facilities and found that conventional municipal treatment achieved greater than 97.5% removal, primarily through granular media filtration or ultrafiltration.
