ClearEvaluation of Potentially Toxic Elements and Microplastics in the Water Treatment Facility
Researchers evaluated potentially toxic elements and microplastics throughout a water treatment facility, finding both contaminant classes present at various treatment stages and raising concerns about the adequacy of current drinking water purification.
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.

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.
Occurrence and identification of microplastics in tap water from China
Researchers analyzed 38 tap water samples from cities across China and found microplastics in all of them, with concentrations averaging around 440 particles per liter. Most particles were smaller than 50 micrometers, and the dominant types were polyethylene and polypropylene fragments. The findings highlight that drinking water treatment plants face a significant challenge in addressing microplastic contamination in the water supply.
Microplastic contamination in Czech drinking water: insights from comprehensive monitoring
Researchers analyzed drinking water from public supply systems across the Czech Republic and found microplastics in nearly all samples, with concentrations ranging from 20 to 180 particles per liter. The most common types were polyethylene-coated paper, PET, and polyester, appearing as both fibers and fragments. The estimated daily intake of microplastics through drinking water was approximately 2 particles per kilogram of body weight per day, though all results fell under European food safety thresholds.
Developing a Methodology for the Testing of Microplastics in Drinking Water Treatment Plants
Researchers developed a standardized methodology for testing microplastic removal efficiency at drinking water treatment plants, including sampling, analysis, and reporting protocols. Having consistent methods is critical for comparing microplastic contamination across different water treatment facilities and establishing regulatory benchmarks.
Size- and Polymer-Specific Assessment of Micro- and Nanoplastics in a European Wastewater Treatment System
Scientists studied tiny plastic particles in European wastewater treatment plants and found that these facilities can remove most microplastics from sewage, but many still escape into the environment. Even though the treatment plants filter out a lot of plastic pollution, the enormous amount of wastewater they process means millions of plastic particles still end up in rivers and oceans every day. This matters because these plastic particles can eventually make their way into our drinking water and food chain, potentially affecting human health.

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.
Removal of microplastics and nanoplastics in water treatment processes: A systematic literature review
Researchers systematically reviewed 103 studies across 26 water treatment plants in 12 countries to assess how well various technologies remove microplastics and nanoplastics from drinking water, finding that while coagulation, filtration, and advanced treatments help, significant gaps remain. The review identifies that no single process achieves complete removal, leaving microplastics as a persistent contaminant in treated water supplies.
Occurrence and analysis of microplastics in municipal wastewater, Poland
Researchers analyzed microplastic contamination in the influent of a large urban wastewater treatment plant in Poland and found an average of about 4 particles per liter. Textile fibers, primarily from clothing, were the most common form of microplastic detected, with polyethylene terephthalate and rubber among the dominant polymer types. The study underscores that laundry and everyday product use are significant sources of microplastic entering the water system.

This review examines how microplastics enter drinking water supply systems, evaluates methods for their detection and removal, and summarizes what is known about their occurrence in treated water. Researchers found that while conventional water treatment removes a significant portion of microplastics, no current method eliminates them completely. The study highlights the need for improved monitoring standards and further research into the long-term health effects of ingesting microplastics through drinking water.
Microplastics in water, from treatment process to drinking water: analytical methods and potential health effects
This systematic review examines how microplastics travel through the water treatment process from raw water sources to your tap and bottled water. The researchers present methods for detecting these particles and assess potential health impacts of drinking microplastic-contaminated water. The findings suggest that current water treatment may not fully remove microplastics, meaning ongoing low-level exposure through drinking water is likely.

The study calls for more research into optimizing treatment processes and developing monitoring strategies specifically targeting microplastic contamination in drinking water.
Microplastics and nanoplastics contamination in raw and treated water
Researchers analyzed 189 samples of raw, tap, and bottled drinking water for micro- and nanoplastic contamination. They found plastic particles in every sample tested, with raw water sources containing the highest concentrations and treated tap water containing the lowest, though contamination was never fully eliminated. The study suggests that current water treatment processes reduce but do not completely remove plastic particles from drinking water.
