Avaliação da qualidade da água de abastecimento do município de Jaçana - RN.

Abstract

Water is an abundant natural resource essential to life on Earth. Brazil is a country rich in water resources, responsible for about 12% of the world total. However, despite the great availability of water resources, the country suffers from the lack of potable water, which is the water that can be consumed taking into account the physical, chemical and biological requirements that determine its quality and guarantee the well-being of the consumer. People living in the semi-arid regions have the lack of water as the main problem to be faced. In order to improve the quality of life for this region's population since the beginning of the century, artesian well drilling has been used as an alternative to the water supply of small communities and herds. The present work has the objective of evaluating the physicochemical properties of samples of artesian wells and a sample of water, coming from the Monsenhor Expedito Adress system, where the Municipality benefits from the resource. The methodology involved four points, totaling 12 samples (three points of artesian wells and one water point of the adductor). The studied parameters were pH, turbidity, chloride content, total hardness, electrical conductivity, total dissolved solids content and sodium and potassium content, through flame photometer. The classification of potability was based on the physico-chemical parameters of the Ministry of Health, Ordinance NO. 5/2017. Most of the physico-chemical parameters evaluated for the well water are not in agreement with the value established by the Ministry of Health. After the study, it can be concluded with regard to the potability of the analyzed water samples that only one of the four points are within acceptable standards for human consumption.
