Análise da conformidade e variação dos parâmetros de qualidade da água distribuída pela ETA Gavião 2023-2024

Abstract

The provision of drinking water in Brazil faces significant challenges, such as the deterioration of water sources and climatic variations, which can compromise the efficiency of treatment systems. The increasing demand for quality water, coupled with the need to meet increasingly stringent potability standards, requires efficient and proactive management of water supply systems. This study aims to evaluate the compliance and temporal variation of water quality parameters in the water distributed by the Gavião Water Treatment Plant (WTP), located in the municipality of Pacatuba, Ceará, based on monthly reports from 2023 and 2024. The methodology included the analysis of data provided by the Companhia de Água e Esgoto do Ceará (CAGECE), focusing on parameters such as turbidity, color, pH, residual chlorine, total coliforms, and Escherichia coli. The results indicated that most samples met the potability standards established by the Ministry of Health's Ordinance GM/MS No. 888/2021. However, seasonal variations in turbidity and color parameters were observed, influenced by climatic factors such as heavy rainfall and strong winds. These variations highlight the need for operational adjustments during periods of greater climatic instability. It was concluded that, although the Gavião WTP maintains an efficient treatment system, the implementation of proactive measures, such as integrated monitoring of meteorological data and preventive maintenance of the distribution network, is essential to ensure the continuous quality of the water distributed to the population.
