ClearIdentifying microplastic contamination in drinking water: analysis and evaluation using spectroscopic methods
Researchers developed analytical methods to identify and quantify microplastic contamination in drinking water, evaluating extraction efficiency and detection accuracy across different water types and plastic particle sizes. The study assessed health implications based on measured plastic loads in treated water.
Assessment of microplastic contamination in drinking water from an italian plant: An analytical study
Researchers analyzed microplastic contamination at multiple treatment stages in a drinking water plant in northern Italy that processes turbid river water supplemented with groundwater, quantifying particles through sedimentation, flocculation, sand filtration, activated carbon adsorption, and disinfection stages.
Fate of microplastics in the drinking water production
Researchers tracked the fate of microplastics through drinking water treatment processes, finding that conventional treatment steps like coagulation, sedimentation, and filtration removed the majority of microplastics but did not eliminate them entirely.
Do drinking water plants retain microplastics? An exploratory study using Raman micro-spectroscopy
Researchers quantified microplastic retention at a Danish groundwater-fed drinking water treatment plant using Raman spectroscopy, finding that the plant reduced but did not eliminate microplastic particles down to 1 micron in size, with some microplastics present in the treated drinking water output.
Microplastic occurrence after conventional and nanofiltration processes at drinking water treatment plants: Preliminary results
Researchers detected microplastics in source river water and finished drinking water at three treatment plants in the Paris region, finding that standard treatment steps including coagulation-flocculation and sand filtration reduced but did not eliminate MPs. Nanofiltration achieved higher removal rates, suggesting advanced filtration is needed for near-complete MP removal from drinking water.
Investigating microplastics at two drinking water treatment plants within a river catchment
Researchers tracked microplastics through each treatment stage at two Czech drinking water treatment plants on the same river, finding that the downstream plant received far higher raw water concentrations (1,296 vs. 23 particles/L) and that current treatment reduced but did not eliminate microplastics from finished drinking water.
Properties and fate of microplastics entering drinking water treatment plants
This conference abstract reviews how microplastics behave as they pass through drinking water treatment plants, noting that while conventional treatment removes many particles, some still reach tap water consumers. It calls for more data on the types and concentrations of microplastics entering and leaving treatment systems.
Occurrence of microplastics in raw and treated drinking water
Researchers analyzed raw and treated water from three water treatment plants and found microplastics in all samples, though treatment reduced particle counts by roughly 70 to 80 percent. The vast majority of detected particles were smaller than 10 micrometers, a size range often missed by other studies. The findings highlight that while water treatment removes most microplastics, very small particles can still pass through conventional filtration systems.
Microplastic Removal in Water Treatment System: A Study of Baghdad’s Wastewater and Drinking Water Treatment Plants
Researchers analyzed microplastic levels at inlets and outlets of two drinking water plants and two wastewater plants in Baghdad, Iraq, characterizing particles by color, shape, size, and composition to assess treatment efficiency and identify residual contamination in treated water.
Differences in the occurrence of microplastic at two technically diverse drinking water treatment plants within the same river catchment
Researchers compared microplastic occurrence in drinking water produced by two treatment plants using different technologies, finding that treatment design significantly affected which and how many microplastics remained in finished water. The results highlight the importance of treatment technology in determining consumer exposure to microplastics in tap water.
Assessment of microplastic contamination in drinking water from an italian plant: An analytical study
Researchers analyzed microplastic contamination in drinking water from an Italian treatment plant that processes turbid surface river water through sedimentation, flocculation, sand filtration, activated carbon adsorption, and disinfection, collecting 1-2.5 liter samples in dark glass bottles for analysis. The study characterized particle types, sizes, and polymer composition at the plant outlet to assess treatment efficacy and residual microplastic levels in finished drinking water.
Differences in the occurrence of microplastic at two technically diverse drinking water treatment plants within the same river catchment
Researchers compared microplastic occurrence in drinking water from two technically different treatment facilities, examining how treatment technology influences the presence and type of microplastics in finished drinking water. The two plants produced water with significantly different microplastic profiles, indicating that treatment technology is a key determinant of microplastic concentrations reaching consumers.

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. Untreated source waters contained between approximately 1,200 and 7,200 microplastic particles per liter, with polypropylene, polyethylene, and polyamide being the most common types. The findings provide valuable data on microplastic exposure through drinking water and the effectiveness of existing treatment processes.

Removal of microplastics via drinking water treatment: Current knowledge and future directions
This review examines what is currently known about microplastics in drinking water systems and how well existing water treatment processes remove them.
