Qualidade da água de poços artesianos em diferentes pontos do Sertão Paraibano.

Abstract

Water from the extraction of aquifers for human consumption must comply with specific legislation in Brazil, which establishes potability standards. In the northeastern region due to water shortages, the use of groundwater has been increasing, mostly from wells. It is important to verify their quality, since these are the ones that most face problems related to possible contamination of the soil. In view of the above, this work had as objective to evaluate the water quality of artesian wells located in the Paraíba hinterland. The following parameters were evaluated: coliforms at 35 ° C, coliforms at 45 ° C, pH, conductivity, apparent color, dissolved oxygen, chlorides, alkalinity and total hardness. From the results obtained, it was observed that the physico-chemical and microbiological parameters evaluated in the water samples, are outside the limits allowed by the Ordinance of the Ministry of Health nº 2914/2011 specifies for artesian wells.
