Resumo:
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.
