The analysis of water quality represents an important chapter in the diagnosis to support decision makers when planning and managing a hydrographic basin. O The present work refers to the analysis of some physical-chemical parameters in an urban stretch of the Pedra Comprida River (tributary of the Sucuru River, sub-basin of the Alto Paraíba region), in the city of Sumé / PB. Samples were collected at different points and evaluated: pH; Electric conductivity; Total Dissolved Solids; Alkalinity; Total hardness; Calcium hardness; Hardness of Magnesium and Chloride. The results were compared with established limits as to the classification of water bodies in class of relevant uses (Resolution 357 of the National Environment Council CONAMA) and drinking water standards (Ordinance 2914/11 of the Ministry of Health). The following were highlighted: the need to adapt this water body to the established limits to which it is classified, class 2; and disagreements over potability. The results aim to assist as a reference between the standard limits of the current legislation and approaches with regard to the management of water resources involving the study area.
