Abstract

This paper aims to make comparative analysis between the environmental aspects of degradation found in the Rio das Bombas river in the city of João Pessoa / PB with the situation in other urban rivers throughout Brazil. The purpose is to show that Brazilian urban rivers are infected usually by the same pollutants that are residues proceeding from a defective system of basic sanitation, moreover, in some regions this system are inexistent, are residues proceeding from residences, industries, not only effluent, but in some solid material cases as sofas, refrigerators, among others, besides the waste that could be recycled, for example, bottle pet. This urban river pollution problems brings public health and environment consequences and in an overview a reduction of water availability in the regions. Methodology: Visits were made in loco in Rio das Bombas river, where the following aspects were perceived; water quality from the ones that were collect and microbiological analysis (total and thermo tolerant coliforms) in seven points by multiple tube methodology as Standard Methods for the Examination of Water and wastewater - 22th edition, where pollution of the river was found also were verified the  motives why the area is degraded,  It was noted the dump of sewage, construction waste, and household waste that were disposed in the surrounding river area, as well as animal husbandry around the riverside, the main points that influence to the pollution of that hydrous body. From these results, comparative studies were made in other rivers in Brazil to state that in general the pollutants found in urban rivers in the city of João Pessoa are the same found in other cities like Sao Paulo that are separated by more than 2500 km from each other. Results: The results of water quality found that the Rio das Bombas river has its source started in a water discharge of the rainwater drainage system, which has already found a pollution level permitted by Brazilian law for both potable and for bathing, and even solid waste such as plastics, tires, and others were found. As it is in an area of a park, the river begins to try for natural process, its own cleaning, where the central part of the pollution level drops a bit, but after receiving an effluent polluted and follows like this for all the analysed stretch. In the seven points collected sample was found the presence of the water quality indicator Coliform. Conclusion: The Rio das Bombas river is in an advanced stage of pollution as well as other Brazilian urban rivers. To recover it a joint action of public power in the revitalization issues will be necessary, control of wastewater and rainfall network, along with the population living in the region so that they don’t pollute the region again.
