QUALIDADE DA ÁGUA PARA CONSUMO HUMANO E DOENÇAS DIARREICAS AGUDAS NO ESTADO DO TOCANTINS

Abstract

The water is a necessary natural resource for life, however, it constitutes a risk factor for health due to its ability to spread physical-chemical and/or biological contaminants, mostly on water intended for human consumption. In this context, the present study aimed to analyze the ratio between the quality of water for human consumption offered by systems (SAA) and collective alternative solutions (SAC) for water supply and Acute Diarrheal Diseases (DDA) in the state of Tocantins, from 2015 to 2020. The methodology of the study was descriptive and exploratory and had as main data source, the Information Systems for Monitoring Water Quality for Human Consumption (SISAGUA) and Epidemiological Surveillance - Acute Diarrheal Diseases (SIVEP -DDA), using selected variables. The results showed that the population coverage by SAA went from 78.04% in 2015 to 83% in 2020 and 2.07% of the population is supplied by SAC in 2020. From 2015 to 2020, about 50% of the samples collected in SAA have Total Coliforms, and the highest frequency of DDA notifications occurred in 2016 and 2017. Furthermore, there are 6 cities without treatment SAA that distribute water to the population. The parameters outside the standard of potability demonstrated a direct influence on the quality of the water, which may cause the transmission of diseases through poor quality water, such as the DDA. However, DDA notifications are not only associated with poor water quality, as other factors may influence on this type of morbidity.
