Avaliação da água do rio Japoré para fins de abastecimento humano

Abstract

The occupation and the use of the land through agricultural activities significantly change the biological, physical and chemical properties of natural systems. These changes, occurred in a watershed can be assessed by monitoring water quality. Through the hydrological cycle, the rainfalls precipitous on the slopes will form the runoff (drainage) surface, which will career sediment and pollutants into the drainage network. Thus, the river is an integrator of the phenomena that occur in the areas of the basin can be evaluated by the parameters of water quality. This research seeks to explore the concept of water quality, influenced by the use and land cover of watersheds. The survey assesses the potential degrading of agriculture practiced in the use of ecologically fragile areas, of the intensive agriculture and the production of waste of animal confinement. Therefore, this research shows the alarming state of the Japoré River, once the contamination was detected by the analytical results obtained from physical-chemical and biological analysis of samples taken along the river and to propose a monitoring control of water quality and mitigation measures.
