Microplastic Contamination in Raw Water Sources from the Phong River Used for Tap Water Production by Local Administrative Organizations

Microplastics, Tap Water, Phong River, ContaminationAbstract
This cross-sectional descriptive study aimed to investigate microplastic contamination in raw water from the Phong River used for tap water production. Raw Water samples were collected from 13 water treatment plants during the dry season (March 2024) and the rainy season (June 2024). The results revealed microplastic contamination in both seasons, with an average of 35.08±18.16 particles per station in the dry season and 42.15±18.09 particles per station in the rainy season, which was 20.15% higher than the dry season. T-test analysis showed a significant difference between the two seasons (p < 0.05). Most microplastics ranged from 150-350 micrometers in size, with fiber being the most common shape in both dry (80.04%) and rainy (72.45%) seasons. The majority were blue in color. The most prevalent polymer types were Polypropylene (PP), followed by Polyethylene (PE). Currently, there are no international or national standards for microplastic contamination in raw water sources or tap water. However, compared to other studies, the level of microplastic contamination in raw water from the Phong River is relatively high. Therefore, it is recommended to study the efficiency of microplastic removal in water treatment systems and assess health risks for consumers. Additionally, promoting public awareness about microplastics is crucial to reduce contamination and long-term health impacts.
