【 摘 要 】

The purpose of the present work was to evaluate anthropogenic influences on the water quality and to offer a subsidy to the establishment of water quality goals in the Jaboatão River Basin (Pernambuco State, Brazil). Eight sampling points were established and were sampled monthly during one hydrological cycle (March/98-February/99). The following variables were analyzed: temperature, pH, conductivity, chlorine, alkalinity, dissolved oxygen, biochemical oxygen demand, fecal coliforms, nitrate, total phosphorus and total solids. The most critical variables related to water quality objectives were dissolved oxygen, fecal coliforms and total phosphorus. Maps of land use, legally protected areas, area industries, and water withdrawals were utilized in order to propose division of the watershed into regions and to provide water quality management information.
