ClearMicroplastic and nanoplastic concentration in tap water in the US
Researchers analyzed microplastic and nanoplastic concentrations in tap water samples across the United States, detecting particles in the majority of samples and characterizing their size distribution, polymer type, and geographic variation.
Occurrence, sampling, identification and characterization of microplastics in tap water: A systematic review and meta-analysis
This meta-analysis of 43 studies found that tap water contains an average of 57 microplastic particles per liter globally, with polyethylene, PET, and polypropylene as the most common polymers in fiber and fragment form. The lack of standardized sampling and analysis protocols has led to widely inconsistent results across studies, making reliable comparisons difficult.
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.
Prevalence and implications of microplastics in potable water system: An update
This review summarizes current knowledge on microplastic contamination in drinking water systems worldwide, covering sources, detection methods, and potential health implications. Researchers found that microplastics are present in both tap and bottled water, with fibers and fragments being the most common types detected. The study highlights the need for standardized testing methods and regulatory limits to protect public health from microplastic exposure through drinking water.
Microplastic and nanoplastic concentration in tap water in the US
This study quantified microplastic and nanoplastic concentrations in US tap water, finding widespread contamination across sampled locations and providing estimates of daily human ingestion through drinking water consumption.
Insights into human exposure to microplastics through drinking water: Current state of the science
This review analyzed 66 studies on microplastics in drinking water from 2018 to 2023 and found that tap water actually contained more microplastics on average (about 62 particles per liter) than bottled water (about 38 particles per liter). Most particles were small fragments and fibers made of common plastics like PET, polyethylene, and polypropylene. The researchers estimate that people ingest roughly 175 microplastic particles per day just from drinking water alone.
Ubiquity of Microplastics in Drinking Water: An Update on Its Assessment and Impact
This review documents the widespread presence of microplastics in drinking water worldwide — including both tap and bottled water — and examines the potential health impacts of ingesting these particles. Current evidence shows microplastics are present in essentially all drinking water supplies at levels that cause concern, though the long-term health effects remain under investigation. The review calls for improved water treatment and reduced plastic use as parallel strategies to address the problem.
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.
A state of the art-mini review on the sources, contamination, analysis, and consequences of microplastics in water
Researchers reviewed global studies on microplastics in water, finding that adults may ingest up to 1.2 million microplastic particles annually through drinking water alone, with secondary microplastics — fragments shed by larger plastic items — being the primary source of contamination.
Synthetic Microplastics in UK tap and bottled water; Implications for human exposure
Researchers tested 177 tap water samples from 13 UK cities and 85 bottled water samples from 17 brands, finding microplastics in every single sample with no meaningful difference in average concentration between tap and bottled water. Infants and toddlers were estimated to ingest four times more microplastics per kilogram of body weight than adults, raising concerns given their still-developing immune and nervous systems.
Presence of microplastics in drinking water from different freshwater sources in Flanders (Belgium), an urbanized region in Europe
Researchers analyzed drinking water from nine treatment plants and nine household taps across Flanders, Belgium, and found low but measurable levels of microplastics (averaging 0.01–0.02 particles per liter), with polypropylene and PET as the most common types. When extrapolating to include smaller particles not detectable by standard methods, estimated exposure rises to roughly 5–6 particles per liter, highlighting gaps in current detection approaches.
Microplastics in drinking water: A review on methods, occurrence, sources, and potential risks assessment
This systematic review found that microplastics are widespread in drinking water worldwide, with most particles smaller than 10 micrometers and composed of polyester, polyethylene, polypropylene, and polystyrene. Standardized sampling and analysis methods are urgently needed, as large variations in reported concentrations make it difficult to accurately assess health risks from drinking water exposure.
Microplastic accumulation, morpho-polymer characterization, and dietary exposure in urban tap water of a developing nation
Researchers analyzed tap water from four major cities in Bangladesh and found microplastics in every sample, with an average of about 35 particles per liter, higher than most other countries studied. The vast majority were tiny fibers less than 0.5 mm, primarily made of polyethylene. The estimated daily intake of about 2.65 microplastic particles per person through tap water alone highlights how people in developing nations may face disproportionate microplastic exposure through their drinking water.
Occurrence and size distribution study of microplastics in household water from different cities in continental Spain and the Canary Islands
Researchers sampled tap water from 24 locations across mainland Spain and the Canary Islands to measure microplastic contamination in household drinking water. They found an average of about 12.5 microplastic particles per cubic meter of tap water, with synthetic fibers being the most common type detected. The study provides one of the first standardized comparisons of drinking water microplastic levels across multiple cities within a single country.
Microplastic pollution in drinking water
This review examines what is known about microplastic contamination in both tap and bottled drinking water around the world. Researchers found that while microplastics have been detected in drinking water at many locations, the reported concentrations vary enormously, making it difficult to draw firm conclusions about relative risk. The study highlights the urgent need for standardized sampling and analysis methods to produce reliable and comparable data on microplastics in the water we drink.
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.
Microplastics throughout a tap water supply network
Researchers evaluated microplastic presence throughout a large tap water distribution network, detecting microplastics at multiple points from treatment plant to consumer taps and finding that concentrations increased along the distribution system, suggesting the pipe network itself as a contamination source.
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: 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.
Microplastic Contamination in Drinking Water: A Review
This review summarized current research on microplastic contamination in drinking water, covering detection methods, occurrence data, and health implications. The authors found microplastics widely present in tap and bottled water worldwide and noted that conventional treatment processes remove them incompletely, raising ongoing concerns about chronic low-level human ingestion.
