Resumo:
The study addresses the importance of water as an indispensable resource for life. However,
water quality has declined significantly due to contamination in the main freshwater streams.
Highlighting that quality water must comply with standards established by the Ministry of
Health. Thus, the characterization of physicochemical parameters allows the assessment of
water status, identifying possible contamination or alterations in its properties is of fundamental
importance for understanding the quality and suitability for various human activities. The aim
of this study was to characterize the physicochemical parameters: pH, Electrical Conductivity,
Alkalinity, Hardness, Turbidity and Chlorides, analyse the results obtained and compare them
with the water potability standards established by Ministry of Health ordinances 5/2017 and
888/2021. In this study, replicate analyses were carried out on water samples collected from
five dams in the rural area of Conceição-PB, notably the following dams: Arraial, Novo, Brunos,
Euzébio and Porções, which are essential for local water supply. The results indicated that the
physicochemical parameters of all the samples analyzed met the drinking water standards.
Therefore, they can be used to provide a safe and adequate supply of water for human activities,
but periodic monitoring of the quality is necessary, considering different rainy and dry seasons,
and in different sections of the reservoirs, which will allow a more comprehensive and accurate
assessment to be made.
