The control of the quality of the water to be consumed by the population is an extremely important activity, the water treatment process presents as a necessary condition for the adequacy of the quality established by the norm, therefore, the control of diseases. The objective of the study is to evaluate and compare the water quality of the distribution network of the Water Supply Systems (SAAs), of the Surveillance Program of the Quality of Water for Human Consumption (VIGIÁGUA) with the data of the Espírito Santo Basic Sanitation Company (CESAN) in the municipalities of Afonso Cláudio, Brejetuba and Ibatiba. The study is a descriptive research, with a quantitative approach that involves an analysis of secondary data on drinking water quality, obtained from the https://www.gov.br and https://www.cesan.com.br sites in the period from 2017 to 2022. For the parameters free residual chlorine, turbidity, total coliforms and Escherichia coli, it is observed that the numbers of samples outside the VIGIÁGUA standard are higher than those of the provider (CESAN) for the free residual chlorine parameter, as for turbidity in a context of comparison, it is found that annually the VIGIÁGUA sampling presented non-standard results in 2022 and that of the provider CESAN are within the standards established in all the years studied. When analyzing the data for the parameter Total coliforms, practically every year there was the presence of total coliforms in the samples taken, but for the E. coli parameter it is possible to see that only in 2022 in the data provided by the provider CESAN was there a presence in the municipalities of Brejetuba and Ibatiba. From the analysis of the data, it is found that there are some non-conformities in the parameters of quality and potability of the water distributed in the municipalities with the legislation. The analysis also favored knowledge about the importance of control and surveillance of water intended for human consumption, however, the lack of investigations that address these actions drew attention.
