Abstract

Water quality is decreasing due to human activities, mainly agriculture and urbanization, in this context the need to evaluate the quality of water through efficient and economical tools, in this way, the objective of this work was to estimate the Quality Index and to compare it with the Rapid Assessment Protocol of Habitat Diversity in two urban streams. Eight points were sampled in the microbasins of the Cumandaí and Tarumã streams, Amambai River. The water quality index was determined by the variables dissolved oxygen, pH, temperature, turbidity, BOD, E. coli, total dissolved solids, nitrogen and total phosphorus. The Rapid Assessment Protocol for Habitat Diversity was used. It was possible to verify that the Water Quality Index (IQA) varied between 46 and 57, and the Rapid Assessment Protocol ranged from 37 to 72. The results obtained for the water quality index and for the rapid assessment parameter are statistically equivalents. However, it is worth mentioning that the methods are complementary, that is, they must be applied together.
