| Abstract | The Saigon River is the major water supply resource for over one million residents in Binh Duong province and for thousands of people living along the river bank. Water of this river is also used for agriculture, industry and aquaculture, etc. In recent years, rapid industrialization and urbanization have resulted seriously polluted. Deterioration of water makes it unfit for drinking purposes. Further deterioration will seriously hamper on aquaculture, agricultural and industrial developments, public health and environmental aesthetics. Therefore, an assessment of water quality in the Saigon River to find out solution for protection surface water becomes more important. In this study, an existing model (QUAL2K) was used as a tool to analyze parameters of water quality such as DO BOD, TSS, TN, TP and Total Coliform. Most of data was collected as the secondary data from related institutions and departments in HCMC. Literature values were used as model parameters. Calibrations and validations were carried out in low-flow and high-flow conditions from Dau Tieng reservoir to HCMC with the length of 114krn. After model parameters were found, the calibrated models were used to assess water quality along the downstream of the Saigon River and the water quality management plans arc recommended for future management activities. It is expected to minimize degradation of water resources, to improve water quality in the river as well as to support the government authorities in controlling and ensuring sustainability of water resources. From the model results, the river water quality is assessed as follow: river water is within standard for drinking, bathing purposes and as well as fish and aquatic life during critical low flow from Dau Tieng reservoir (km 0) to Thu Dau Mot Station (km 60). Especially, non-point sources of pollution from domestic and runoff water which is discharged from canals around HCMC is identified to be main sources declining water quality. Application model is also used to predict fluctuation of water quality along the Saigon River in 2010. The results demonstrate that water quality at Ben Than (new intake water treatment plant) is still satisfied with Vietnamese standard for supply water (TCVN 5942 - - 1995) with conventional treatment, even in a critical low flow (20.5m3/S) . The concentration of pollutants along the Saigon River is lightly decreased by reduction of pollutants discharge from industrial zones. Surface water in the downstream can be used for HCMC domestic water supply without pumping from Dongnai River, if domestic wastewater from canals is efficiently treated. |
