Abstract: Water is a vital natural resource for human survival and development. Its inefficient management generates conflicts and inequalities, especially in areas with disorganized urban expansion where water pollution is a growing environmental problem, such as in the municipalities located within the Guandu Hydrographic Region (RH-II). The discharge of sanitary and industrial effluents without adequate treatment into the Guandu River's contribution area, which is part of RH-II, negatively impacts the environment and public health, considering that the water intake for supplying approximately 9 million inhabitants of the state of Rio de Janeiro comes from this water body. Given this scenario, public authorities must define strategic actions to ensure a balance between anthropic activities and water resources. In this regard, the present study, using data extracted from the Procon Água platform, aimed to perform a diagnosis of industrial effluent discharge in the strategic municipalities of the RH-II, as well as to characterize the effluent discharge from four activities located in the municipalities of Queimados, Paracambi, Japeri, and Seropédica. After evaluating the main parameters reported in Procon Água, including BOD (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand), it was verified that the effluent organic load from each of the activities during the analyzed period (January to December 2022) is minimally representative when compared to the quantity of organic load derived from untreated sanitary sewage discharged directly into the receiving bodies tributary to the Guandu River during the same time interval."
