The Cimanuk River downstream is part of local community activities in the watershed. Uncontrolled waste disposal from these activities will have any negative impact on the water quality of the river and resulting polluted river. This study aims to analyze and assess water pollution in the Cimanuk River downstream. Analyze water quality of the Cimanuk River downstream based on the standard of Government Regulation of the Republic of Indonesia (INA), Regulation of the Governor of West Java (WJP), United States Environmental Protection Agency (US EPA), and Department of Environment (DEO). The pollution index method used to assess the water in the Cimanuk River downstream from years 2015 to 2017. Water sampling site of Cimanuk River downstream was at Kenanga, Bojongsari, Sindang, and Paoman in Indramayu District, West Java Province. This study found that five parameters (Temperature, TSS, BOD, COD, and DO) do not meet the water quality standards with the value of Temperature (30.91±0.68 °C), TSS (62±47.75 mg/L), BOD (21.82±27.42 mg/L), COD (42.29±47.05 mg/L), and DO (4.06±2.45 mg/L). The impact of water pollution causes a decrease in water quality annually. Pollution index value of the Cimanuk River downstream ranging from 1.40 to 17.06. The water quality status of Cimanuk River downstream has been changing from slightly polluted to highly polluted. River water pollution indication due to uncontrollable waste disposal from domestic waste, batik industry, crackers industry, regional public hospital, car wash, traditional and modern market waste along the Cimanuk River downstream. Therefore, a strict environmental law enforcement from the local government to polluters needed to control water pollution in the Cimanuk River downstream in the future.
