Water quality assessment of Cisadane River using pollution indicator parameters

Abstract

The Cisadane River catchment area is approximately 1,375.43 km2, and it is one of the main rivers in Banten and West Java Province, Indonesia. The Cisadane River has an important function in supporting the lives of many people with all their activities. Most of the studies related to the assessment of the water resources quality have used through several water quality indices, Those are are water quality index (WQI), water pollution index (WPI), and river habitat survey (RHS). However, the study of determining pollutant sources in the river has less done, including Cisadane River in this case. This study aimed to identify the important environmental parameters that can be used as indicators of pollution in the Cisadane River. This research was conducted in 2007-2014 by collecting water samples, 2-4 times every year. Employing the box and whisker statistical method, it can be concluded that free chlorine (Cl2), biological oxygen demand (BOD), chemical oxygen demand (COD), phenol, total coliform and E.coli were reliable indicators of contamination in The Cisadane River. As an indicator of pollution in the Cisadane River 6 these parameters can be used as a basis for assessing the quality of Cisadane water.
