Water is one of the essential natural resources for the survival of living beings, in addition to contributing to the maintenance of natural cycles, especially hydrological. However, such a resource is liable to be degraded by human activities carried out in inappropriate ways, thus compromising the availability and quantity of this resource. This work aimed to elaborate a diagnosis of the environmental impacts in the waters of the Piancó-Piranhas-Açu River in the stretch located between the cities of Pombal - PB and Paulista - PB. The methodology used was based on bibliographic searches in scientific and technical sources, field visits, photocumentation and consultations with public agencies. Therefore, the area was georeferenced using geoprocessing tools. Then, the cataloging of anthropic activities with an impacting potential and the identification of environmental impacts in the river's waters were carried out, using the EIA methods: Ad Hoc, Check Lists and Interaction Matrix. In addition, control measures were indicated. According to the results, 52 impacts on the river's waters were identified, with 43% “very significant”, 36% “significant” and 21% “not significant”. Finally, it is expected that the results obtained in this study will serve as a basis for future environmental studies in the waters of the Piancó-Piranhas-Açu river.
