    (Universidade Federal do Pará, 2014) NORMANDO, Margareth Neves; NASCIMENTO, Fernanda Souza do
    The city of Manaus is growing fast and chaotic way since the event of the Zona Franca de Manaus (ZFM) and Polo Industrial de Manaus (PIM) in the 70 and 80, causing environmental devastation of the surrounding forest and pollution of its unprecedented urban streams, condemning the quality of its waters and annihilating or expelling and a significant portion of the local fauna and flora. The Programa Social e Ambiental dos Igarapés de Manaus (PROSAMIM) became the most important reaction for the environmental restoration of streams of the Amazon capital. The waters of its streams found themselves not only putrid and formed an immense carpet of garbage containers "pet", continuously collected for public cleaning of municipal power. This work has as main objective to know the water quality of Igarapé Mestre Chico, Programa Social e Ambiental dos Igarapés de Manaus - PROSAMIM, Manaus / AM, and specific objectives to raise the results of analyzes of water from the Igarapé do Mestre Chico in the period January 2011 to January 2012 and show the quality of the waters of the Igarapé do Mestre Chico, contextualizing their indicators and the evolution of their health and urban context. The methodology adopted was based on the literature, both for the study of the subject as now proposed for the compilation of existing data on the water quality of the Igarapé do Mestre Chico. It was found that the samples collected from the point No. 01 (Igarapé Mestre Chico: Viaduct José Claudio de Souza); point No. 02 (Igarapé Mestre Chico: Av. Tarumã - Quarter Square 14); point No. 03 (Igarapé Mestre Chico: Lookout), low dissolved oxygen ranging from 1 to 4.82 mg O2 / L and higher concentrations thermotolerant coliforms (460 - 93x104 NMP / 100mL), biochemical oxygen demand (8,6 - 56.5 mg O2 / L), total phosphorous (0.201 to 3.7 mg P / L) and ammonia (<0.01 to 22.03 mg N / L). The values nitrate (0.1 to 6.81 mg N / L), turbidity (3.48 to 86.0 mg / L) total dissolved solids (6.03 to 240.0 mg / L) lie in the acceptable range of CONAMA Resolution 357/05. These results show that the waters of the Igarapé do Mestre Chico still polluted despite improvements made by PROSAMIM.
