Water quality depends on natural conditions and use and occupation of the watershed and its knowledge is essential in the management process of recursoso water. The river is a tributary of Siriri river basin Japaratuba is an important source of water for human consumption and irrigation, and its main tributaries and rivers Siriri Vivo and Morto. Thus, this study aims to analyze through physico-chemical parameters of water quality in river basin Siriri and its seasonal variation. The monitoring was performed in 7 samples campaigns between February 2010 to November 2011, with the following parameters: temperature, pH, electrical conductivity, color, total dissolved solids, hardness, dissolved oxygen, ammonia, nitrate, nitrite, total nitrogen, phosphate, total phosphorus and chlorophyll-a. The river Siriri Vivo shows good water quality unlike Siriri Morto River, which has been indicative of eutrophication. |
