ClearMicroplastics 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.
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.

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 treatment – Current knowledge and research needs
This review examines the current state of knowledge about microplastics in drinking water treatment, including how treatment plants remove these particles.

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.
What have we known so far about microplastics in drinking water treatment? A timely review
This review summarizes research on microplastic occurrence and removal in drinking water treatment, covering both laboratory and full-scale studies through August 2021. Researchers found that conventional treatment processes like coagulation-flocculation, membrane filtration, and sand filtration are generally effective at reducing microplastics in water, though results vary widely depending on conditions. The study identifies key factors influencing removal efficiency and highlights the need for further research on nanoplastics in drinking water.
A critical review on recent research progress on microplastic pollutants in drinking water
This critical review synthesizes research on microplastic contamination in drinking water sources and treatment systems. The study highlights that microplastics have been found in rivers, lakes, and treatment facilities worldwide, and that bioaccumulation of these persistent particles through drinking water represents a potential concern that requires further investigation into health effects and improved removal technologies.
Microplastics in Water: Occurrence, Human Health Impact and Methods of Analysis
This review covers the occurrence of microplastics in water sources globally, summarizing human health impacts from ingestion and inhalation, and evaluating available treatment technologies for removing microplastics from drinking water. The authors conclude that conventional water treatment is insufficient for complete microplastic removal.

This review examines the occurrence, fate, and treatment of micro- and nanoplastics in drinking water sources, covering how these particles enter water supplies and what treatment technologies exist to remove them. The authors note significant gaps in both detection methods and removal efficiency.
Microplastics: review of removal methods for drinking water production
This review examined methods for removing microplastics from drinking water, responding to the growing detection of microplastic contaminants in rivers, lakes, reservoirs, and both tap and bottled water. The review surveys emerging treatment technologies capable of addressing microplastics as pollutants in drinking water production, synthesizing evidence on removal efficiency, limitations, and practical applicability for water utilities.
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.

Researchers reviewed the key sources of microplastic contamination in drinking water — including plastic waste, synthetic clothing, and microbeads in personal care products — and assessed strategies for reducing exposure through improved treatment technologies and stricter regulations on plastic production. The review emphasizes that effective policy, combined with public awareness about single-use plastics, is essential for protecting drinking water quality.
Occurrence and fate of microplastics from a water source to two different drinking water treatment plants in a megacity in eastern China
Researchers tracked microplastics through two drinking water treatment plants in a major Chinese city and found that treatment removed 73-83% of microplastics from the water. However, some microplastics were still present in the treated drinking water, and chlorine disinfection actually increased polystyrene levels. The smallest particles (2-5 micrometers) were the hardest to remove, which is a concern because smaller particles may be more easily absorbed by the human body.
Microplastics toxicity, detection, and removal from water/wastewater

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.
