Water quality assessment at Bedadung River in Jember Regency

Abstract

River water quality assessment plays an important role in determining the allocation of surface water resourses. The purpose of this study is to identify the pollution load capacity and the status of water quality assessment using the Canadian Council of Ministers of the Environment (CCME WQI) method. Monitoring of water quality and discharge parameters is carried out at 5 locations of water sampling. The BOD, COD, TSS, and discharge parameters in the observation period of 2019 were used to measure the value of the pollution load capacity. Water quality input data in the form of physical, chemical, and microbiological parameters in the 2016-2019 observation period were used to determine the water quality index value using the CCME WQI method. The results showed that the value of the pollution load capacity of the Bedadung River pollution in the urban area segment of Jember Regency refers to TSS, BOD, and COD parameters respectively are 17 429.99 kg/day, 410.75 kg/day and 2 357.33 kg/day. The range of Bedadung River CCME WQI values for the Urban segment of Jember Regency from 2016-2019 is 53.21-79.31 category fair to marginal categories. The parameters that cause low CCME WQI values are BOD, COD, H2S, Cl-, PO4, and total coliform.
