Maintaining quality of fresh water, sanitary and environmental aspects, is essential. Once the environmental degradation caused by human activities is more intense. In this direction, the main objective of this study was to evaluate the water quality and environmental conditions of stretches of watershed located in watersheds that are used for public water supply of the cities of Trindade (Bacia Hidrográfica do Ribeirão Arrozal), Goianápolis (Bacia Hidrográfica do Ribeirão Sozinha), Terezópolis (Bacia Hidrográfica do Córrego dos Macacos) and Nerópolis (Bacia Hidrográfica do Córrego Água Branca), cities that compose the Metropolitan Region of Goiânia. To this end this research was organized in articles divided into three chapters. The first chapter corresponds to characterize the environmental conditions of the Bacia Hidrográfica do Ribeirão Sozinha. This chapter have been identified and related the main impacts in the watershed and in rivers, furthermore, were verifying the use and occupation of the soil that could cause potential impacts on water resources with the objective to evaluate the combined use of three methodologies the survey of the environmental status of this basin. The second chapter corresponds to functional trophic categorization community of aquatic macroinvertebrates and characterization of ecological conditions of river reaches that compose the four watersheds listed above. The third chapter discusses the evaluation of water quality and assessment of environmental conditions, of the same river reaches studied in the previous article, by evaluating the structure of the macroinvertebrate community, the implementation of a protocol for rapid assessment of habitat conditions evaluation and physico-chemical parameters of water. Moreover, the latter paper aims to inform about the organization of macroinvertebrates front environmental conditions during periods the dry and rain season. The results of the evaluation of ecological conditions indicated that all watersheds studied in this study are suffering or have suffered from human impacts from agricultural activities. This fact may be affecting the water quality of water sources that supply the Trindade, Goianápolis and Nerópolis, because some physico-chemical parameters such as the total nitrogen and the total phosphorus were not in conformity with limits for Class 2, and were within the limit that is recommended for class 4, according to CONAMA resolution 357/2005. The assessment of water quality through of aquatic macroinvertebrates indicated good quality in all segments surveyed. Assessment of trophic groups allowed a better understanding of how macroinvertebrates were organized against the environmental conditions of each region. The seasonal evaluation of macroinvertebrate community indicated that the richness and abundance did not vary significantly between seasons.
