Research on assessment of suface water environment and sediment in seawater shallow area in Bac Lieu Province and proposing solutions for protection

Environmental pollution along the coast of Binh Thuan province, caused by the discharge of wastewater into the main river basins from the mainland

“…Figure 2 shows the wastewater flow generated in each river basin, notably the Cai Phan Thiet river and its surroundings, the Phan river and its surroundings, the Ca Ty river, and the Luy river, with the total received wastewater discharge are 20607.6 m 3 /day, 12977.7 m 3 /day, 11061.8 m 3 /day and 12034.4 m 3 /day, respectively. These river basins account for most of the area of Binh Thuan province, flowing through areas with diverse concentrations of production and waste discharge activities [8,9].…”

“…The total flow of wastewater generated on the river basins (m 3 /day).Depending on the characteristics of each commune, district, town, and city, each river basin will receive different flows and sources of wastewater.Figure2shows the wastewater flow generated in each river basin, notably the Cai Phan Thiet river and its surroundings, the Phan river and its surroundings, the Ca Ty river, and the Luy river, with the total received wastewater discharge are 20607.6 m 3 /day, 12977.7 m 3 /day, 11061.8 m 3 /day and 12034.4 m 3 /day, respectively. These river basins account for most of the area of Binh Thuan province, flowing through areas with diverse concentrations of production and waste discharge activities[8,9].According to Circular No. 21/2009/BTNMTregulations on economic and technical norms for investigation and assessment of wastewater discharge status and wastewater receiving capacity of water sources[10], the research has also investigated, surveyed and statisticed on the number of waste sources according to each flow group.…”
