Water quality from artesian wells in the northeastern semi-arid region: A literature review

Resumo

Water from artesian wells usually has high levels of salinity, a factor in which potability standards must be analyzed in order to ascertain whether it is suitable for human consumption and other activities. The objective of this work was to present studies carried out on the analysis of the quality of water acquired through artesian wells in the northeastern semi-arid region, noting the possibility of using them in adequate conditions for human consumption. Data were collected through a literature review of research already carried out in this area that found results on the physical-chemical and microbiological aspects of water samples in different artesian wells located in different points of the northeastern semi-arid region. Based on the studies carried out, it is clear that in most of the water resources coming from artesian wells in the semi-arid northeast, it is necessary that the appropriate treatment be made for its use, thus making water within the required potability standards. It is concluded that, in view of the results obtained, the water obtained through artesian wells needs treatment before being destined for human consumption.
