    Water quality (WQ) pollution is a matter of concern to everyone, and it is necessary to take remedial measures to protect human life. This paper presents the assessment of surface WQ through the ... Water Quality Index (WQI) followed by the Vietnam Standard QCVN 08-MT:2015/ BTNMT combined with satellite data for the Dau Tieng reservoir. The implementation method is based on the correlation of each WQ indicator with the spectral features of satellite images to build a regression function, simulating the spatial distribution of the entire reservoir. The Sentinel2A satellite images were used with reflective bands in the visible and near-infrared (NIR) spectrum region. The regression functions showed that the correlation of the WQ indicators was related to single bands, and the band ratios include blue and NIR, red/blue, green/blue, and NIR/blue bands. Simulation results of the WQI spatial distribution expressed that the WQ of the Dau Tieng reservoir was in a polluted state at the level of WQI fluctuation in the range of 0–50 for the most part. Dau Tieng irrigation system plays a vital role in the water distribution system for Tay Ninh province and the southern key economic region. Therefore, appropriate treatment measures should be taken if it needs to be used for domestic water supply purposes.
