Monitoring and assessment of the canal surface quality in Binh Duong province

Abstract

   The purpose of thisstudy aims to assess the surface water quality of canals in Thuan An town, BinhDuong province in the period of 2015 - 2017. Monitoring of surface water is carried out in the dry andrainy season at 9 locations of canals belong to the studying area. The research assessed the quality ofsurface water sources at monitoring places showed Cat stream (M1), Bung canal (M3), channel D (M7)and Binh Hoa canal (M8) were clearly affected sites from domestic and industrial wastewater.Economic growth and urbanization were themain reasonslead to the pollution risk and canals' surfacewater quality degradation. The studying results showed that the pollutant concentrations did not meetthe National Technical Regulation on surface water QCVN 08-MT:2015/BTNMT. The study revealedthe surface water quality situation were high contamination in almost of the monitoring areas.Findingsof statistical analysis for TSS, COD and BOD5 parameters also showed the great fluctuations andstatistically significant difference during the monitoring period (P<0.05).Therefore, the managementagencies should be prevented effluents discharged into the canals from human activities in the future.
