| Abstract | The water quality is one of the elements that can potentially indicate human activities in watersheds. This study was based in water analysis conducted at Sao Miguel river basin, located in karstic terrain in Upper Sao Francisco basin. Monthly, during a year, samples were collected at 5 gauge stations in Sao Miguel river to monitoring 13 water quality variables. Those, which had demonstrated human influences, were studied spatially and temporally. Sewage discharge from urban area, although its relatively small size, was the main factor of water pollution in the river, being responsible for microbiological contamination, resulting in waterborne disease cases - schistosomosis was reported at the middle sector of the river. The effects of rural activities in water quality decay were evidenced at rainy season due soil erosion at, both in the up and low river course. The variables analyzed did not indicate clearly effects of limestone mining in the water quality, nonetheless it represents the major economic activity at the region. |
