		abstract={Water quality is a characteristic of water that characterizes the condition of water that can still be used with the provisions of water quality standards. The waters of Sungai Lumpur are a coastal area that has a strategic position as a center for community activities that are utilized by local residents as a residential area which also has quite a lot of resident activities, including agriculture, aquaculture and household activities. This study aims to determine the water quality of the Lumpur River based on the concentration and distribution of detergent, free chlorine, BOD and COD and to determine the relationship between environmental parameters and water quality parameters. The results of this study found that the concentrations of Detergent, free chlorine, BOD, and COD in Sungai Lumpur waters were in the range of 0.07?0.22 mg/l; 0.02-0.44 mg/l; 2.91-6.74 mg/l; and 33-85 mg/l. Water parameters that have a high contribution to the BOD parameter are DO and salinity on the F1 axis (45.61%). Detergent content, free chlorine, and COD do not have a close relationship with environmental parameters.}
