ClearOccurrence 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 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.
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.
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.
Identification and Quantification of Microplastics in Potable Water and Their Sources within Water Treatment Works in England and Wales
Researchers tested eight water treatment works in England and Wales and found that conventional treatment processes removed 99.99% of microplastics, reducing raw water concentrations of about 5 particles per liter to near-zero in drinking water. Polyethylene, PET, and polypropylene were the most common polymers found in the raw water supply.
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.
Analytical Review of Microplastics Occurrence in Bottled Water, Tap Water, and Wastewater Treatment Plants
This review analyzes microplastic contamination across bottled water, tap water, and wastewater treatment plants using data from studies worldwide. Researchers found that microplastic levels in drinking water are closely tied to the water source and that packaging type significantly influences contamination, with glass bottles recommended over plastic. The study emphasizes the need for improved water treatment technologies and greater public awareness about microplastic exposure through drinking water.
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.
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 removal of microplastics in three drinking water treatment plants and commercial bottled water brands in Jordan
Researchers found tiny plastic particles called microplastics in all drinking water sources they tested in Jordan, including tap water from treatment plants and bottled water from stores. While water treatment plants removed 65-81% of these plastic particles, they couldn't eliminate them completely, and bottled water actually contained slightly more microplastics than treated tap water. This matters because people are drinking these plastic particles every day, though scientists are still studying what long-term health effects this might have.
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.
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.
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.

Microplastics in Drinking Water: A Review of Sources, Removal, Detection, Occurrence, and Potential Risks
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.
Mass Concentration and Removal Characteristics of Microplastics and Nanoplastics in a Drinking Water Treatment Plant
Researchers measured both microplastics and nanoplastics by mass throughout an entire drinking water treatment plant, finding that raw water contained about 9.6 micrograms per liter of plastic polymers. Treatment reduced this by roughly 92%, but nanoplastics and very small microplastics were harder to remove than larger particles. The study highlights the importance of measuring plastic contamination by mass, not just by particle count, for a more accurate picture of exposure through drinking water.
Occurrence of Microplastics in Tap and Bottled Water: Current Knowledge
This review summarizes current research on microplastic contamination in both tap and bottled drinking water. Researchers found that microplastics are present in both water sources, with bottled water generally containing higher concentrations than tap water, and smaller particles being more abundant. The study raises public health concerns and emphasizes the need for improved detection methods and drinking water treatment standards.
