The need to use water resources forced the urban agglomerates to grow along the rivers, but the increasing urban occupation increased the problems of water management in the cities, especially in relation to the release of domestic effluents and the drainage of rainwater. The present work aimed to evaluate physical-chemical and microbiological variables in water samples collected in urban rivers located in Salvador-Bahia. Collected at two distinct points of the Lucaia and Jaguaribe rivers, in the rainy and in the dry period, they showed that both physico-chemical and microbiological parameters, in most cases, presented values above those indicated in current legislation, especially the second point of the Lucaia river that presented levels of EC, TDS, chloride and hardness superior to the other points investigated. The comparison of these results with INEMA Monitora program data indicate that these rivers are impacted by inadequate discharges of domestic effluents during the period investigated.
