Heavy Metal Pollution and Water Quality assessment in Belik River Yogyakarta

Nowadays, surface water pollution, particularly in the river, is a serious problem which happens in the worldwide, i.e. wastewater. The wastewater may contain of heavy metals which can be harmful to the human body. Belik River is a river that passes through Yogyakarta city. The river is potentially experience pollution from domestic waste, industrial waste, and hospital waste. The purpose of this research is to find the initial condition of metal exposure in Belik River and its effect on some water quality parameters, such as Dissolved oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), TSS, TDS, pH, Electric Conductivity, Salinity, Iron (Fe), Copper (Cu), and Lead (Pb) were tested in this research. The result shows that physical dan chemical parameter of water quality in Belik river such as TSS and BOD exceed the water quality standard (WQS) (Class II), but for the other parameters were under WQS. The heavy metal was found under the ASS detection for Pb and Cu, meanwhile the Fe concentration was below the WQS. © Published under licence by IOP Publishing Ltd.
