Global prevalence of microplastics in tap water systems: Abundance, characteristics, drivers and knowledge gaps
A global analysis of tap water from 34 countries found that microplastics were present in 87% of over 1,100 samples tested, with particles smaller than 50 micrometers being the most common. When researchers looked for particles as small as 1 micrometer, concentrations were more than 20 times higher than studies that only counted larger particles. This means that most people worldwide are regularly drinking microplastics in their tap water, and the true extent of exposure has likely been underestimated.
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 Drinking Water: A Review

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.
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.
Microplastics in Drinking Water:Current Knowledge, Quality Assuranceand Future Directions
This review synthesizes current knowledge on microplastics in drinking water, covering their occurrence in source waters, behavior during treatment processes, and potential health implications. Researchers found that while drinking water treatment plants remove a portion of microplastics, standardized quality assurance methods are still lacking. The study calls for improved monitoring protocols and treatment technologies to better address microplastic contamination in tap 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.
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.
Recent occurrence of microplastics in freshwater and efficiency of available treatment technologies
Researchers reviewed six years of global data on microplastics in freshwater systems, finding them in rivers, lakes, and groundwater across five continents, with conventional water treatment removing 85–95% of larger particles but struggling with smaller fragments. The review also found that nanoplastics may be 10–100 times more common than microplastics yet remain nearly impossible to detect with current technology.
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.
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. Researchers found that while conventional treatment steps like coagulation and filtration do reduce microplastic levels, significant amounts can still persist through to tap water. The study calls for more research into optimizing treatment processes and developing monitoring strategies specifically targeting microplastic contamination in drinking water.

Researchers developed and tested a technology for controlling microplastic contamination in drinking water, targeting particles at concentrations relevant to typical tap and bottled water exposure. The solution demonstrated effective removal of microplastics from drinking water under realistic treatment conditions.
Polymers of micro- and nanoplastics in household tap water of Barcelona
Researchers quantified micro- and nanoplastic polymers in the 0.7-20 micrometer size range in household tap water from the public drinking water network of Barcelona, Spain, using a novel workflow designed to capture smaller particle sizes than most previous studies. The cross-sectional study found microplastics present in drinking water at concentrations relevant to human daily exposure assessment.
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.

Profile and Different Approaches for Size Characterization of Microplastics in Drinking Water from the Lisbon Water Supply System
Researchers characterized microplastic particles in drinking water from the Lisbon water supply system and compared two methods for measuring particle size. They found an average of 196 microplastic particles per liter, with polyethylene accounting for over 77% of the identified polymers. The study demonstrates that different size measurement approaches can yield significantly different results, highlighting the need for standardized methods in drinking water microplastic analysis.
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.

Problems, Challenges, and Removing Methods of Micro Plastics from Water
This review examines the presence of microplastics in drinking water — both tap and bottled — and the technologies available to remove them. Microplastics have been detected in drinking water worldwide, and while conventional treatment removes some particles, smaller nanoplastics largely pass through. The authors assess filtration, coagulation, and advanced treatment options for improving microplastic removal in drinking water systems.
Microplastics in Drinking Water: Assessing Occurrence and Potential Risks
This review paper examines how widespread microplastics are in drinking water — from rivers and lakes to groundwater — and what health risks this contamination may pose. The authors call for urgent research into how microplastics move through water treatment systems and ultimately reach taps, emphasizing that current sampling and analytical methods are inconsistent, making it hard to compare studies or set safety thresholds. For people drinking tap or bottled water daily, understanding and regulating this exposure pathway is a pressing public health priority.
