Assessment of surface water quality along Pazundaung Creek, Yangon City

Abstract

This study focuses on the assessment of water quality at seven sampling points along the Pazundaung Creek in Yangon. Moreover, the determination of BOD, COD, DO, TH, EC, Cu, Cl, TDS, pH, turbidity and temperature were carried out. Water samples had been collected in February, March, April and May. According to the findings of this study, the water quality of Pazundaung Creek was deteriorated due to the rapid urbanization and industrialization along this creek. Therefore, the sources of these types of wastewater should be carefully controlled by applying the effective waste management systems and appropriate wastewater treatment technologies to prevent the water pollution of this creek. All of the results from sampling analyse were compared with Malaysia Water Quality Standard of class IIA and class IIB. According to the standard limitations of Malaysia Water Quality Standard, this type of surface water needed a conventional treatment process to use as water supply. In the case of fishery, the sensitive aquatic species can survival in these limitations and can also be used for recreational use with body contact.
