Caracterização dos parâmetros físicos-químicos de amostras de água das cidades de Bayeux, Santa Rita e João Pessoa, pertencentes ao Estado da Paraíba.

Abstract

Water plays a crucial role in sustaining life and is used in various ways in human daily life. However, the water consumed by the population must meet the standards set by the Ministry of Health. In this context, this study aimed to analyze the quality of water from the Paroeira River and tap water from some homes located in the cities of Bayeux, Santa Rita and João Pessoa, in the state of Paraíba, based on the physical-chemical parameters of potability defined by Ordinance No. 5/2017 and Ordinance No. 888/2021 of the Ministry of Health. Samples were collected in March 2023 and pH, conductivity, alkalinity, hardness, turbidity and chloride content were measured. The results indicated that the tap water samples from the cities of Bayeux and João Pessoa complied with the standards set by the Ministry of Health. However, the sample from Santa Rita had a pH outside the limits set by the Ministry of Health and the sample from the Paroeira River exceeded the Maximum Permitted Values for the Hardness and Chloride parameters. In addition, the Electrical Conductivity of the Paroeira River sample reached a value of (3132 ± 31) μS.cm-1, indicating the possibility of contamination or pollution from effluent discharge. Thus, the results observed highlight the importance of additional studies for a comprehensive assessment of the water quality of the study sites.
