Abstract

The agricultural activity is the main consumer and polluter of water resources, where deforestation, irrigation and waste from such activity are carried to the drainage network This study aimed to analyze spatially and temporally the physical, chemical and microbiological characteristics of surface waters of the Paraíso River, and classify the water body according to CONAMA Resolution 357/05. Water samples were taken in different periods, in August (dry season) and in November (rainy season). The parameters evaluated were: water temperature, pH, electrical conductivity, salinity, turbidity, dissolved oxygen, fecal coliforms, phosphorus and nitrogen. The results of for fecal coliform and phosphorus showed that the stretches of samples water from located in the areas of agricultural had higher unsuitability according to CONAMA Resolution 357/05, classifying the river as Class III.
