Tributaries serve as essential features of the Saigon River. The work consists of a case study on the selection of sites for tributaries of the Vam Thuat River flowing through Go Vap District and District 12, Ho Chi Minh City, Vietnam. An objective is to assess its pollution status and risks of those pollutants by using Nemerow’s Pollution Index (NPI) for water quality assessment and Pearson’s correlation (r) values, indicating a significant and positive correlation between variables of the same group. There are ten research sites to study the surface waters of the tributaries from upstream to downstream. Grab samples of surface water sources were collected on October 19, October 26, November 2, and November 9, 2017, based on the national technical regulation on water quality standards of Vietnam. The monitoring parameters include temperature, pH, total suspended solids (TSS), chemical oxygen demand (COD), ammonium-nitrogen (NH4+-N), nitrate-nitrogen (NO3–-N), phosphate (PO43–), sulfate (SO42–) and total iron (Fe). According to the measurement results and statistics, the mean values of the samples from ten research sites were compared with the Vietnam national standard system and WHO guidelines. Contaminants of TSS, COD, NH4+-N, SO42–, and Fe should be specifically discussed and compared with previous studies to update available data for management and suggestion of industrial monitoring of these tributaries using water quality sensors.
