ABSTRACT
The Brazilian environmental law determines the monitoring and classification of streams that pass through urban centers, with subsequent publication of results, however, in most cases this does not occur effectively. The objective was to monitor the Pampa stream and Bells river upstream of the mouth of the brook, in the city of Novo Hamburgo - RS. The determination of the physical-chemical and microbiological tests included: pH, temperature, dissolved oxygen (DO), biochemical oxygen demand (BOD), total phosphorus (P) and total nitrogen (N). These tests were performed by the Analytical Center at the University Feevale. The waters of the Pampa stream had, for some parameters, similar to domestic sewage. The impact caused the waters of the Rio dos Sinos by the stream is related to domestic sewage. The solution to the current bad conditions chemical and microbiological water from the stream Pampa inevitably the construction and operation of systems for treatment of domestic sewage.Key-words: water quality; monitoring; Pampa Stream.
