nÃo hà / A preocupaÃÃo com processos que causam degradaÃÃo da qualidade dos recursos hÃdricos e dos ecossistemas aquÃticos tem se acentuado, principalmente, devido a enorme quantidade de poluentes e novas substÃncias que adentram nesse meio. Objetivou-se, com este trabalho, ampliar o conhecimento sobre a comunidade de macroinvertebrados aquÃticos do reservatÃrio GaviÃo em Itaitinga (CE), onde ocorre a captaÃÃo das Ãguas para o sistema de abastecimento de Ãgua da regiÃo metropolitana de Fortaleza e avaliar como os organismos respondem à disposiÃÃo dos resÃduos da ETA GaviÃo, utilizando o Ãndice BMWPâ. As coletas foram realizadas mensalmente, empregando um coletor do tipo Surber (500 Âm de abertura de malha) no perÃodo de outubro 2012 a maio de 2013. Foi coletado um total de 1.621 espÃcimes, distribuÃdos em 23 taxa. Mollusca foi o grupo dominante e frequente e Insecta apresentou maior riqueza. Segundo o Ãndice BMWPâ, verificou-se que o reservatÃrio GaviÃo encontra-se com suas Ãguas em qualidade duvidosa. / Concerns with the processes that cause water resources and ecosystem degradation are on the rise, especially because of large amounts of pollutants and substances that enter this medium. This study aimed to evaluate water macroinvertebrate communities in tanks used for water collection for urban use and to assess how organisms respond to waste generated in the water treatment plant. We collected a total of 1,621 specimens, distributed into 23 taxa. Mollusca was the dominant and frequent group and insecta was the most abundant. Based on feeding mode, there are more predatory organisms in relation to scrapers. We found no eudominant families. By using the BMWPâ score we verified that water quality in the âGaviÃoâ reservoir is questionable.
