The increasingly population and the growth of the cities, allied to the natural desire of man to raise the level and quality of life, has resulted in problems such as water pollution and degradation of mangroves. In the state of Paraíba, the Sanhauá river, which composes the Paraíba do Norte river estuary, is located very close to downtown in the city João Pessoa, the capital of the state, in a fully urbanized area and therefore presents problems of degradation that directly affect the life quality of the residents in their sides. The former Roger´s open dump is also seated in this area and was decommissioned in 2003 after nearly 40 years of operation. This fact aggravates even more the environmental problems and public health of the population that lives nearby. Thus, the main objective of this study is the evaluation of the water quality and the existing conflicts of its use in the Sanhauá river estuary, in the area of influence of the former Roger open dump. To achieve this objective, it was done, over a period of two years, the collection of information and data of the study area. It was used as research resources, visual investigation and photographic record of polluting sources, the use of questionnaires with the residents directly affected by the former Roger´s open dump and monitoring the quality of superficial water at four collection points (two upstream and two downstream from the former open dump). The analysis of water were performed at the sanitation laboratory of the Federal University of Paraíba. The former Roger´s open dump is still producing leachate that flows to the Sanhauá River mangrove, nevertheless there were several points of pollution with discharge of domestic wastewater and solid waste directly into the river. Comparing the quality of the superficial water with the fresh water class III quality standards, in which is classified the Sanhauá river, and the class I standard of brackish water, it was found that the parameters of this water exceeds the limits recommended by the CONAMA resolution 357/05. It can be concluded that the former open dump is still a major pollution source of the Sanhauá river, but it is not the only one, since the communities included in its influence area are being deprived of sanitation, so the waste is released directly into the river. Furthermore, as the deposit of household waste in the river at the same time there were other activities such as fishing, navigation, recreation (river bath), which in itself shows conflicting uses of water.
