【 摘 要 】

It was evaluated Quality Parameters of Superficial Water in Springs in Jales �? SP, its importance, not only as a vital natural resource but also as a quantity, quality and by its availability to be used by the community and its interaction with environmental factors associated to the hydrographic basin. The area was chosen based on the fact that it´s constitutes at one of the sub-basins of São José dos Dourados River and doesn’t have any kind of studies or environmental analysis for academic aims. It was evaluated the following parameters: oxygen chemical demand, oxygen biochemical demand, turbid, total coliforms and E. Coli. For 12 months, samples were collected monthly from seven stations of Marimbondinho and Tamboril Streams and also of Marimbondo River and trimestrally from two stations at the effluent of the Frigorífico (cold store) in the water of the receiver bodies and check the treatment efficiency of industrial effluents (of this cold store) and also its influence on the pollution levels in the streams and rivers which werestudied; measuring the pollution indicators (parameters) previously mentioned and also supply the integrated regional planning and the sub-basin preservation with subsidies andconsequently the hydrographic basin of São José dos Dourados River. We concluded that throuing domestic sewer and industrial liquid residues of the cold store increasessensitively the pollution levels of the water of receiver bodies as for the parameters studied; after all, the treatment made on the effluent of the cold store isn't enough toreduce the pollutant charge to recommended levels to be thrown into the streams.
