EVALUATING THE QUALITY OF DOMESTIC WATER AND DRINKING WATER FOR STUDENTS IN THANH HOA, VIETNAM

Abstract: This study was conducted to evaluate the quality of domestic (non-drinking) and drinking water used by students in Thanh Hoa, based on 51 domestic water and 51 drinking water samples collected from student boarding houses and dormitories. The samples were analyzed against several parameters specified in the Ministry of Health’s National Technical Regulation QCVN (Vietnamese Standard) 02/2009/BYT (Ministry of Health) and the recommendations of the EPA (2025). The results indicate that the majority of the water samples met the safety standards, satisfying the basic quality requirements for both domestic use and direct consumption. The water sources generally exhibited good clarity, were odorless and tasteless, maintained a stable pH level, and showed no significant contamination. However, some samples demonstrated variation in quality, particularly concerning the Total Dissolved Solids (TDS) index, which may be linked to differing storage conditions, piping systems, or water supply sources. The study affirms the crucial role of clean water quality in general, and clean water for students in particular. Furthermore, the research recommends the need for close monitoring of clean water quality, periodic inspection, and strengthened measures for maintaining water supply infrastructure. The research findings contribute a scientific basis for urban environmental management and the protection of student public health.
