Sustainable Watersheds: Assessing the Source and Load of Cisadane River Pollution

Abstract

Abstract-Cisadane watersheds is a very valuable strategic area for the people in Tangerang District, Banten, Indonesia. But that strategic value has brings an impact in the form of water pollution, that comes from its popullation and economic activities. This water pollution load is necessary to know its source, and also how much, so that public, private and local governments can jointly take action to restore the water quality of the Cidasane River. The purpose of this study is to determine the pollution load in the Cidasane watersheds. The study will taking sample of Cisadane River water as an inputs in the isoyet map pollution dispersion modeling. And calculating the load in the river using QUAL2Kw modelling. The results of the modeling are then analyzed to obtain the amount of Cisadane River pollutant load. The pollution load in this study will be focused on BOD, NO3, and Total P, and Salinity. This research has shown the inter-regional pollution spread on the Cisadane river, which used This study will provide a measurable data of the type and scale of the pollution load in Cisadane, as an input for Cisadane River water quality restoration policy making by the Government of Tangerang.Index Terms-Cisadane river, Isoyet map, pollution load, QUAL2Kw model, sustainable watersheds.

“…Cisadane river consist of uncontrollable growth of algae [7]. Cisadane River is used because it has an abundance of 19 types of phytoplankton and 10 types of zooplankton [8]. Domestic wastewater used in the experiment obtained from mixed influent domestic wastewater treatment plant.…”

“…This is due to waste from industrial activities but has little impact on the exposure of COD values to the Bedadung River. The degradation of organic matter and dilution of COD concentrations were also influenced by additional water discharges from various sources such as springs and creeks, as well as variations in the flow velocity due to topographic variations [GUMELAR et al 2017;PRADANA et al 2019a;RAHAYU et al 2018]. In other cases, the BOD values for all points were below the class I quality standards.…”

“…The higher concentration of NO3-N and PO4-P in the water column will affect the uncontrolled growth and abundance of phytoplankton, which will automatically affect the oxygen deficiency in the water [14]. The PO4-P can be originated from agricultural activities, mining, fertilizers and animal waste [15] and the excessive value may cause HABs. Most nitrogen input to the coastal ecosystem originated from anthropogenic factors compared to the industrial sectors [16].…”
