To meet the proposed objectives, we carried out a series of methodological procedures such as the analysis and spatialization of data referring to the parameters Nitrate (NO³), Thermotolerant Coliforms (CT) and the identification of the presence of the bacterium Escherichia coli (E. coli) obtained through continuous monitoring of water quality carried out by the São Gonçalo do Amarante (SAAE) Autonomous Water and Sewage Service (SAAE) between 2019 and 2019, the complementary monitoring of the Nitrate and CT parameters between 2019 and 2020, in addition to the analysis of the Monitoring Database of Acute Diarrheal Diseases (MDDA) for each Basic Health Unit (UBS) inserted in the study area. Such actions sought to identify the relationship between the quality of the water distributed to the population and the cases of diseases associated with water transmission. The preliminary results indicate that the water supply to the population of the municipality is carried out exclusively by capturing and distributing water obtained through abstraction in underground wells that have the treatment of simply adding chlorine.

The examination of the Nitrate parameter indicates the presence of contamination of organic origin, at different levels, in all the points analyzed in the study area, pointing out the need for intervention by the government and the concessionaire due to the collected water being destined for human consumption and its contamination can bring serious health risks to the population. The results obtained with the development of the research will subsidize the development of proposals for the management of water resources in São Gonçalo do Amarante aiming to improve the quality of the water distributed to the population and specific actions related to health for the current and future generations referring to the disease of waterborne diarrhea.
