Microplastics (MPs) have been found in both surface water and groundwater, which are sources of drinking water. Since one of the most important routes for MPs to enter the human body is through drinking water, the enormous buildup of MPs in waterbodies and the resulting effects on human health have caused social concern. However, our knowledge of drinking water treatment plant (DWTP) treatment techniques affects the removal of MPs, and there aren’t any standardized or efficient quality assurance and quality control (QA/QC) measures for sampling and analysis. The current state of MPs in drinking water sources is described in this review, which also provides the most recent data on MPs removal by various DWTP units. Lastly, we propose practical QA/QC techniques to ensure the accuracy of MP analysis. This review intends to present the most recent data on MPs in drinking water and the effectiveness of MPs removal by DWTP units. It also advises that further research into the mechanisms of MPs removal be done in the future.
