RESUMO:

The man-nature relationship and the concern with the availability of natural resources, especially water, is present in the most important world conferences on the environment, being included in the 2030 Agenda as part of the 17 Sustainable Development Goals that aim at actions that guarantee water quality, protection and restoration of aquatic systems, as well as the areas that house these resources, for the sustainability of water on the planet and protection of biodiversity. In this sense, the sources of the humid forest of Chapada do Araripe-CE have great relevance for the guarantee of the local environmental, social and economic development, therefore, being equally important for the protection of the biodiversity of the aquatic fauna. From this perspective, this research has as main objective to carry out a faunal survey of aquatic macroinvertebrates and to evaluate the environmental quality of the area and waters of the sources, with the hexapods and aquatic mites of the humid forest, thus contributing to the Agenda 2030. The sampling was carried out in nine sources, between the months of January and April 2020. The vegetation, gravels, sediments and debris collected from the sources were passed through a granulometric sieve of 30 cm in diameter and mesh with pores of 0.25 mm, being the sampling effort 10 min at 10 m away from the source and 10 min at the point where the water is born. The material was placed in an 80 mL container with 70% alcohol. Invertebrates were extracted from the sample using the Kero-float extraction method (kerosene flotation). Screening was performed under a stereoscopic microscope. The faunal analysis of the families of aquatic macroinvertebrates collected was carried out using indices of abundance, relative abundance, frequency and richness. The environmental quality of the surroundings of the area was evaluated by the Environmental Impact of Springs Index (IIAN) and the quality of the waters of the sources was evaluated from the Biological Monitoring Working Party (BMWP) index. Statistical analyzes were performed with the R software. With the study we demonstrated that there is a certain diversity of hexapod families in the evaluated springs that favors their use in studies on water quality. The IIAN indicated sources with a degree of protection: "Excellent" (3); "Good" (2); and "Reasonable" (4). The BMWP index indicated "Good" water quality for the Valentim I and Valentim de Cima sources; "Acceptable" for Tremedor; "Doubtful" for Batateiras de Baixo, Coqueiro I, Pending, Saco e Saquinho I; and "Criticism for Batateiras de Cima". The occurrence of Hydracarinas of the morphospecies Hydryphantidae sp.1, Hydryphantidae sp.2, Limnesiidae sp. and Mideopsis sp., which represents the first records of mites for the sources of the phytoecological unit of the humid forest, in Chapada do Araripe, Ceará, Northeast of Brazil and of the species Rhynchohydracarus dividuus, which is the first record of occurrence of this species for the Brazil. Considering that this resource is a topic of interest in all dimensions of Sustainable Development (social, cultural, environmental, territorial, economic and political) and essential for the survival of present and future generations, it is essential to implement mitigating, recovery and , protection and preservation of these resources and their area, thus ensuring the maintenance of biodiversity and local development.
