Type: article
Abstract: Objective: To evaluate the water quality of the Campos-Macaé canal, located in Campos dos Goytacazes/RJ, in order to identify possible environmental impacts resulting from anthropogenic activities and support actions aimed at the management and preservation of water resources. Theoretical Framework: The research is based on concepts of water quality and environmental monitoring, according to Resolution CONAMA No. 357/2005, and on studies addressing the degradation of water bodies influenced by agricultural and industrial uses. Method: Water samples were collected at two distinct points along the canal, analyzing physicochemical parameters (pH, dissolved oxygen, conductivity, turbidity, nitrate, and nitrite) and microbiological indicators (thermotolerant coliforms). The results were compared to legal limits and interpreted according to scientific literature. Results and Discussion: Variations were observed between the sampling points, indicating different patterns of degradation. The pH, dissolved oxygen, nitrate, and nitrite remained within acceptable limits, while turbidity, conductivity, and thermotolerant coliforms indicated anthropogenic influence, especially in the rural section, where agricultural and industrial activities are predominant. Research Implications: The results highlight the need for mitigation measures, continuous monitoring, and environmental education to promote the canal’s sustainability. Originality/Value: This study provides an updated diagnosis of the water quality of the Campos-Macaé canal, emphasizing gaps in legislation and strengthening the debate on integrated water resources management in the region. Furthermore, this canal holds historical, environmental, and socioeconomic importance for the North Fluminense region of the state of Rio de Janeiro (Brazil).
