Monitoramento e avaliação da qualidade da água proveniente de solução alternativa coletiva de abastecimento de condomínios residenciais em Russas-CE

Abstract

The Jaguaribe Valley, a hydrologically exceptional region in Ceará, has a higher volume of groundwater due to its sedimentary domain and the access to the largest watercourses in the State. However, potability issues persist in some water supply systems in the region, contrary to the obligations established by Ordinance GM/MS no 888/2021. In this research conducted in the municipality of Russas - CE, an alternative collective water supply solution was monitored. Nine parameters were analyzed in accordance with current legislation. The results showed that five parameters did not comply with drinking water standards, including total dissolved solids, chlorides, total hardness, total coliforms, and E. coli. These problems were also identified in bibliographic research in neighboring cities such as Morada Nova and Itaiçaba. This highlights the lack of water quality surveillance and the presence of contamination in the water distributed by the alternative solution during the analyzed period.
