Surface water resources and community health are issues of concern in developing countries, including Vietnam. Water pollution has taken place in many places, especially in Ho Chi Minh City. Wastewater is a cause of canal pollution including large amounts of soluble inorganic compounds and even large amounts of heavy metals in water. Therefore, it is necessary to have research to survey and evaluate water quality. The research team carried out many projects on water resource management, for example, the study and assessment of surface water quality of a tributary of Vam Thuat river, Ho Chi Minh City, from October 19, 2017 to November 9, 2017, evaluated based on QCVN 38:2011/BTNMT (National Technical Regulation on Surface Water Quality to Protect Aquatic Life). The stability of the experiment was evaluated through 4 different sampling times. Samples were collected, preserved, and analyzed in the laboratory using standard methods. Water parameters include temperature, pH, total suspended solids (TSS), chemical oxygen demand (COD), NH4+-N, NO3–-N, PO43--P, sulfate (SO42-) and Fe. After completing this research topic, a part of the content was presented at an international conference, details as follows: “Risk Assessment of The Vam Thuat River Water Quality for Safety Water Supply to District 12, Ho Chi Minh City. Accepted Paper in Proceeding at REACT International Conference of Climate Change Challenges for The Lower Mekong Basin Region: Findings, Crucial Problems And Lessons Learned From Action Plans To Date with Grand number (#573964- EPP-2016-1-ES-EPPKA2- CBHE-JP)” in Ho Chi Minh University of social science and humanities, organized from 19-20th September 2019, p. 94.
