URBAN SANITARY CONDITIONS AND BATHING WATER QUALITY OF THE ENSEADA AND SÃO LOURENÇO BEACHES, MUNICIPALITY OF BERTIOGA, SÃO PAULO (SE, BRAZIL) / CONSEQUÊNCIAS DAS CONDIÇÕES SANITÁRIAS URBANAS DAS PRAIAS DA ENSEADA E SÃO LOURENÇO, MUNICÍPIO DE BERTIOGA-SP, NA QUALIDADE DAS ÁGUAS DESTINADAS À BALNEABILIDADE

Abstract

Brazilian coastal zone comprises more than 8,000 km of extension, which together with the tropical climate, increase the interest of the coastal tourism in the coastal zone. Consequently, the demand for services in coastal cities, such as basic sanitation, is also increasing. In this way, the evaluation of the beach waters quality is of great relevance, since the contact with contaminated water can raise the exposure to pathogenic microorganisms and with this the transmission of waterborne diseases. The objective of this study was to evaluate the balneability of two beaches (Enseada and São Lourenço, municipality of Bertioga, São Paulo State, SP, Brazil) using sanitary conditions as indicators. The soil coverture and sanitary sewage system were related to the quality of the beach waters. For the analyzed period (2010 to 2016) a direct correlation (R = 0.58 and R = 0.46) was observed between the monitoring stations balneability using the criteria of the “Conselho Nacional do Meio Ambiente” (National Council of the Environment) CONAMA 274/2000 and the World Health Organization, respectively, and the index of the sanitary sewage system for the region, similarly, the coefficient of determination (R²) presented values of 0.34 and 0.21. The results of the applied methodology allowed a satisfactory evaluation of the water quality of selected beaches and suggested that the São Lourenço beach has a better sanitary sewage system and, consequently, a better bathing water quality and lower risks to the bathers health, while the Enseada Beach presented regular indices due to the lack of a sewage collection system in most of this settlement area. ResumoA zona costeira brasileira compreende mais de 8.000 km de extensão, que aliada ao clima tropical, aumentam o interesse pelo turismo no litoral. Consequentemente, também aumenta a sobrecarga nos serviços das cidades litorâneas, como o de saneamento básico. Dessa forma, a avaliação da qualidade das águas praiais é de grande relevância, pois o contato dos banhistas com águas contaminadas pode elevar a exposição a microrganismos patogênicos, e com isso a transmissão de doenças de veiculação hídrica. O objetivo deste estudo foi avaliar a balneabilidade de duas praias (Enseada e São Lourenço, município de Bertioga-SP, SE Brasil) utilizando-se as condições sanitárias como indicadores. Para isto, buscou-se relacionar a cobertura do solo e esgotamento sanitário com a qualidade das águas das praias. Para o período analisado (2010 a 2016), observou-se uma correlação direta (R = 0,58 e R = 0,46) entre a balneabilidade dos pontos de monitoramento (critérios da Resolução CONAMA 274/2000 e da Organização Mundial da Saúde, respectivamente) e o índice de esgotamento sanitário da região; de maneira semelhante, o coeficiente de determinação (R²) apresentou valores 0,34 e 0,21. Por fim, os resultados mostraram que a metodologia utilizada permitiu avaliar a balneabilidade das praias selecionadas de forma satisfatória. Assim, a praia de São Lourenço demonstrou melhores condições de esgotamento sanitário e, como consequência, melhor balneabilidade e menores riscos à saúde dos banhistas, enquanto que a Praia da Enseada apresentou índices regulares em decorrência da inexistência de rede coletora de esgoto na maior parte de sua área.
