In it flow into Pirangi Watershed (PW), whose water receives large amounts of pollutants, mainly domestic and industrial sewage from districts where pass the rivers that consist it, compromising, thus, the bathing water quality of the Pirangi beach. Bearing in mind the importance of water sanitary quality to ensure an environment that no present risk to the bathers s health, this work had as main objective to assess the influence of the PW s waters in the bathing water quality of the Pirangi beaches. To that end, were made collections of water in the beaches and in the rivers with the intention of quantify the fecal contamination indicators thermotolerant coliforms and enterococci, to then classify the conditions of bathing water quality according with the CONAMA Resolution number 274 of 2000. For the purposes greater knowledge about the health conditions of the Beaches Pirangi and about the influence the PW s waters exert on it, was done parallely to the study of the water quality, an investigation of the sand sanitary quality. Furthermore, it was made an evaluation of the PW s Water Quality through Water Quality Index (WQI). Starting from the results obtained in the research present was possible to verify, among other aspects, that the entry of the PW s waters in the Pirangi beaches exerts direct influence in the bathing water quality of the same ones, being the North Pirangi beach (point tracking PA-02) the most influenced. There was noticed also a significant reduction in the conditions of bathing water quality of the beaches in the rainy season. However, the precariousness do sewerage system of the Natal metropolitan region and the absence of a right system of treatment an final disposal of domestic sewage and industrial are the main factors responsi le for deterioration of the PW s Water Quality, and as a consequence, compromising the bathing water quality of the Pirangi beaches / A praia de Pirangi est? localizada no litoral oriental do Estado do Rio Grande do Norte, nos munic?pios de Parnamirim e N?sia Floresta. Nela des?gua a Bacia Hidrogr?fica Pirangi (BHP), cuja ?gua recebe grande quantidade de poluentes, principalmente esgotos dom?sticos e industriais dos munic?pios por onde passam os rios que a comp?em, comprometendo, dessa forma, a balneabilidade desta praia. Tendo em vista a import?ncia da qualidade sanit?ria da ?gua para se garantir um ambiente que n?o apresente riscos ? sa?de dos banhistas, o presente trabalho teve como objetivo principal avaliar a influ?ncia das ?guas da BHP na balneabilidade das praias de Pirangi. Para tanto, foram realizadas coletas de ?gua nas praias e nos rios com o intuito de quantificar os indicadores de contamina??o fecal Enterococos e Coliformes termotolerantes, para ent?o classificar as condi??es de balneabilidade de acordo com a resolu??o CONAMA n? 274 de 2000. Para efeito de maior embasamento sobre as condi??es sanit?rias das Praias de Pirangi e sobre a influ?ncia que as ?guas da BPH exercem sobre elas, foi realizada, paralelamente ao estudo da qualidade das ?guas, uma investiga??o da qualidade sanit?ria das areias. Al?m disso, foi feita uma avalia??o da qualidade da ?gua da BHP atrav?s do ?ndice de Qualidade da ?gua (IQA). A partir dos resultados obtidos na presente pesquisa foi poss?vel constatar, dentre outros aspectos, que a entrada das ?guas da BHP nas praias de Pirangi exerce influ?ncia direta na balneabilidade das mesmas, sendo a praia de Pirangi do Norte (ponto de monitoramento PA-02) a mais influenciada. Observou-se, tamb?m, redu??o significativa nas condi??es de balneabilidade das praias na esta??o chuvosa. Contudo, a precariedade do esgotamento sanit?rio da regi?o metropolitana de Natal e a aus?ncia de um sistema adequado de tratamento e disposi??o final dos esgotos dom sticos e industriais s?o os principais fatores respons?veis pela degrada??o da qualidade da ?gua da BHP, e como conseq??ncia, pelo comprometimento da balneabilidade das praias de Pirangi
