%X The impacts of precipitation on the water quality along the Purus river, located in the Brazilian State of Amazonas, was investigated using TRMM 3B42 data and information about water acquired in four different areas along the river. The Purus river is located in one of the most natural environment of the Amazon Basin. Although this area is well protected, all villages of the area are found in some places along of the river course. In order to know the relationship between the Purus water quality and other factors like precipitation and deforestation, samples of the water quality obtained if four different places of the river stream were analyzed together with remote sensing images. The parameters evaluated (temperature, conductivity, turbidity, pH and solids in suspension) revealed significant correlation when compared to the precipitation regime. Weak values were found for water quality versus deforestation. The human impacts are noted in the area where the land use is more intense. In those places the parameters turbidity and solids in suspension are more affected. All pH values showed strong acidity of the water and the it can be caused by the high acidity of the soil, although other factors can be associated to this phenomena.
