Introduction: The evaluation of water quality parameters is fundamental for public health and disease prevention in the population. Objective: To perform an analysis of surveillance data of chemical, physical, and microbiological parameters to evaluate the quality of water for human consumption in the  State of Amazonas, based on the Information System of Water Quality Surveillance for Human Consumption (Sisagua). Method: An exploratory-descriptive study based on quantitative research was carried out to analyze quality of human consumption water and chemical, physical, and microbiological parameters, measured in water samples in the State of Amazonas, from 2016 to 2020. Nonparametric statistical tests were performed to compare differences in the proportion of each category and adequacy according to the geographic microregion. Results: Inland micro-regions have a lower proportion of municipalities with data recording of water quality parameters. The water samples from the microregion of the capital presented lower free residual chlorine content, higher fluoride concentration, and higher values for apparent color and turbidity. Trend analyses showed improvements in parameters for apparent color in samples obtained in the capital microregion and, for free residual chlorine, total coliforms and Escherichia coli in water samples collected in the interior of Amazonas. Conclusions: There were differences in the profle of chemical, physical, and microbiological parameters of the samples evaluated according to the locality. The need for improvements in the management of water quality surveillance is emphasized, especially related to looking carefully at the actions of analysis and supervision in the State of Amazonas.
