Analysis of water pollution problem Belawan waters

Abstract

Abstract Indoor This study was conducted to determine water pollution conditions and pollutants entering Belawan waters. Exploration research methods are carried out about water pollution in Belawan of Indonesia. Data on pollution in Belawan is categorized as polluted where the average level of lead-heavy metal in the body of blood clams in Belawan coastal waters reaches 0.042 ppm, the analysis results of Pb metal in Belawan waters in the Electric Steam Power Plant (PLTU) area (24, 12 ppm), mangroves (26.91), and the area around fishermen (11.18 ppm), all of which have passed the quality standard threshold. Water Quality Management and Water Pollution Control related to Pb Quality Standard based on the attachment of PP no 82 of 2001 is Pb < 0.1 mg/L. The content of COD and BOD in water was studied to describe the amount of organic matter dissolved in the water, in the study stated that COD and BOD are indicators to determine water quality. The physical and chemical conditions of Belawan waters are still in the feasible category, measured from Ph, BOD, and DO which are still within the proper limit, this is because the ecosystem and natural habitat are still in balance, then seen from the high diversity of macrozoobenthos, it can be said that polluted with medium-high categorized in Belawan waters.
