ANÁLISE DA QUALIDADE DA ÁGUA PARA CONSUMO HUMANO DE SOLUÇÕES ALTERNATIVAS COLETIVAS E A OCORRÊNCIA DE DOENÇAS DE VEICULAÇÃO HÍDRICA NO ESTADO DO TOCANTINS

ANALYSIS OF WATER QUALITY FOR HUMAN CONSUMPTION OF COLLECTIVE ALTERNATIVE SOLUTIONS AND THE OCCURRENCE OF WATERPROOF DISEASES IN THE STATE OF TOCANTINS

Abstract

Access to quality water is a basic human right, therefore, public water supply must be sanitarily safe to prevent the spread of diseases. Collective alternative solutions (SAC's) facilitate water contamination because most of them are not treated. This work aims to analyze the relationship between the quality of water for human consumption, offered by the SAC's, with waterborne diseases in the state of Tocantins, between 2016 and 2021. The methodology of the work is descriptive and exploratory and used data from the Systems Information Surveillance of Water Quality for Human Consumption (SISAGUA), Notifiable Diseases (SINAN) and Epidemiological Surveillance - Acute Diarrheal Diseases (SIVEP-DDA). Based on the results, it was found that the population coverage by SAC's increased from 1.16% in 2016 to 1.51% in 2021, corresponding to 24,044 inhabitants who consume only SAC. Of these, 94% of people use water from underground springs, however, 87% use untreated water. In the period from 2016 to 2021, approximately 50% of the samples collected contained the presence of total coliforms and the highest frequency of ADD cases occurred in the period 2016 and 2017, with values of 55,429 and 51,984 cases, respectively, and the highest number of notifications of ADD. Hepatitis A was in 2016 with 14 cases. Qualitative data demonstrate a direct influence on water quality and on the spread of diseases, however, the results of notifications of ADD and Hepatitis A are not only associated with poor quality, but also with other factors contributing to the spread of this morbidity.
