Water quality of river Santa Maria do Doce

Abstract

Aimed to evaluate the water quality of the river Santa Maria, as backing for a proposal to manage its waters, from the collection of water samples at various points of the river. Was considered as the point of collection, the districts bordering the Santa Maria riverbed and points against its tributaries, with collections before the entrance of the river in the district and after his departure from the district, from its source in the hills of ice in Santa Teresa, to the town of Colac. The collection was made on 23 points, before and after the districts, collecting five samples per local. The collection points for water samples were defined considering the suspected pollution of the local communities where they are located, caused by deforestation, lack sewage, garbage and pesticides. The evaluation was made based on parameters, physical, chemical and biological where this information, we observe that this bowl is in the median state of degradation. By analyzing all the data regarding the quality of water resources it appears that these point to low quality of these resources, which endangers the health of the resident population in the basin, as these are used not only for irrigation, but primarily on human supply. The River Santa Maria do Doce has contaminated much of his bed, being considered unfeasible for human consumption.
