Avaliação da qualidade sanitária da água distribuída pelo sistema de abastecimento em Poço Verde - SE no período de janeiro a outubro de 2019

Abstract

The Rio Real hydrographic basin bathes the county of Poço Verde / SE, and it is responsible for the city’s water supply. Working to reduce the risks of waterborne diseases, the Ministry of Health established drinking standards to be followed by the companies responsible for distributing the product for human consumption. Given the above, this research aimed to evaluate the microbiological and physical-chemical quality of water in two educational establishments, from January 2019 to October 2019. The latest available data, through the analysis of the physical-chemical’s results and microbiological parameters of the samples collected monthly by the municipal surveillance and by the state’s sanitation company, comparing them to the current standard, using a methodology based on bibliographic, documentary research and technical visits by municipal health surveillanceinspectors –VISAM, with sampling of data, all procedures followed the methodologies recommended by the Ministry of Health. The results were divided into two groups: 1. Physical-Chemical Quality and 2. Microbiological, being exposed in the form of tables and graphs, making easier the assessment and interpretation based on the current standard. It is worth noticing the divergence between the values acquired by the two bodies and the changes in Free Residual Chlorine, Color and Turbidity in rainy months, reflecting the presence of Total Coliforms. It is concluded that the found results were a result of the pluviometric factor’s combination index, the tightness in the network and failures in the integrity of the SAA, in addition to the absence of the Municipal Basic Sanitation Plan, thus confirming the research hypothesis.
