%X O presente trabalho objetivou a avaliação da qualidade ambiental das nascentes do rio Bacanga utilizando uma metodologia pouco empregada nesse tipo de estudo, a Teoria Fuzzy. No cálculo do Índice de Qualidade Ambiental das Nascentes, para a ponderação dos parâmetros foi utilizado o AHP (Analytic Hierarchy Process - Processo Analítico Hierárquico). Como resultado, das 11 nascentes analisadas,5 nascentes foram enquadradas na classe A com Qualidade Ambiental Ótima, 3 nascentes foram enquadradas na classe B com Qualidade Ambiental Boa, 2 nascentes foram enquadradas na classe C com Qualidade Ambiental Razoável e 1 nascente foi enquadrada na classe D com Qualidade Ambiental Ruim, nenhuma nascente foi enquadrada na classe E com Qualidade Ambiental Péssima. O uso da Lógica Fuzzy com o AHP mostrou-se eficiente na classificação das nascentes. As nascentes enquadradas nas classes C e D necessitam de medidas mitigadoras para a recuperação ambiental das mesmas. A urbanização foi identificada como o principal agente de degradação das nascentes estudadas. ABSTRACT: This study aimed to evaluate the environmental quality of the river Bacanga sources using a methodology rarely used in these types of studies, the Fuzzy Theory. In calculating the Environmental Quality Index of Sources, for the weighting of parameters was used the AHP (Analytical Hierarchical Process). As a result, the 11 sources analyzed 5 sources were framed in class A with Environmental Quality Best, 3 sources were framed in class B with Environmental Quality Good, 2 sources were framed in class C with Environmental Quality Reasonable and 1 source framed in class D with Environmental Quality Poor, no source was framed in class E with Environmental Quality Rubbish. The use of Fuzzy Logic with AHP demonstrated to be efficient in the classification of sources. The sources classified in the C and D classes require mitigation measures for the environmental recovery of the same. Urbanization was identified as the main agent of degradation of the studied sources.
