    Water is a natural resource of great importance for the maintenance of human life and a public good, as described in art. 1 of Law 9433/97 which provides for the National Water Resources Policy. The importance of water is not only related to its functions in nature, but the role it has in health, economy and quality of human life. Water quality is an indispensable aspect when it comes to its main uses, especially for purposes such as human supply and the supply system must favor this aspect. With this, the objective of this study was to carry out an analysis of the water quality of the Conjunto Olival Tenório Costa in Campo Alegre, Alagoas, and to evaluate the functioning of the local supply system through the perception of the local residents. During a period of four weeks, 500ml of water were collected in the eight blocks of the complex, totaling 32 samples in the end, where the physical-chemical analyzes were carried out. In possession of the results obtained through the analyses, the potality standard established by the legislation was detected. In all analyses, it was possible to observe that only in the analysis of the fourth week a pH of 6 was obtained, whereas in the others, below, the values were lower, also having oscillations between the results. Regarding the presence of color, it was found that there was no presence of free residual chlorine in any of the possible analyses. After carrying out the physicalchemical analyzes of the water and noticing some irregularities in the face of the legislation, the objective was also to evaluate the perception of the local residents about the quality of the water and the supply system through a virtual interview via electronic means, where 120 residents participated, and of this number, 75.5% were female. Regarding the quality of the taste of the water that arrives at the residences, 45.8% classified the taste of the water as bad, when asked if the handlers had already witnessed any alteration in the water, 76.7% of them said yes. And finally, 54.2% of those approved classified the supply system as bad. Finally, it is concluded that the water distributed to the population of Conjunto Olival Tenório Costa has already interfered in the issue of health of the inhabitants, and the responsible authority must remain vigilant to possible future health projects.
