Water is a fundamental factor for the life of all living beings, as long as its quality conforms to the basic requirements of potability. Issues that deserve support from the public power and civil society, which unfortunately go unnoticed and require effective interventions. Natural resources are being explored more frequently every day because of the rapid population growth in general, making demand more than expected.

The objective of this study was to analyze if the quality of the water distributed in the village of Cacimbas, rural area of Barreiras of Piauí, is in accordance with the potability standards. The methodology consisted of the physico-chemical parameters that were analyzed in this study, followed the criteria established by Decree No. 2,914, of December 2011 of the Ministry of Health, and Resolution CONAMA 357, both to perform the diagnosis of the samples that were collected with their features.

Due to the water, which is consumed by the population not having proper treatment, may have caused these serious problems with the water that is distributed in the locality.
