Abstract
Pollution of canals and creeks has been an urgent issue in Ho Chi Minh City (HCMC). Canal pollution not only worsens the urban beauty but also greatly affects surroundings and public health. Built on the land with a 600m long of Lang creek running through, the third campus serving most teaching and learning activities of Van lang university will also be affected by pollution of Lang creek. Mutually, these activities would increase the pollution level of Lang canal if wastewater generated from Van Lang university will be untreated before discharged into Lang creek. The study results showed that current water quality of Lang creek was polluted by organic substances, N-NH4+ and microbiological indicator in both dry and rainy seasons when compared with QCVN 08: 2015/BTNMT. However, if compared with QCVN 14: 2008/BTNMT, the water of the canal was polluted just by the N-NH4+ and microbiological parameters in both seasons. Besides, the pollutant load of the discharging sources and the reception capacity of Lang creek that flowing through the third campus of Van Lang University were also estimated in detail in this study. In addition to improving the water quality and environment of the creek, renovating solutions are also proposed in this paper. Besides, this study showed that Van Lang university’s activities would not exacerbate Lang creek’s pollution.
