Achados recentes sobre a qualidade da água do rio cocó em um trecho urbano da cidade de Fortaleza – Ceará

Abstract

The Cocó River is currently the largest water body in the municipality of Fortaleza. Its spring is located in the Aratanha Mountain, running through several cities and neighborhoods within Fortaleza’s municipality, until it meets the sea at Sabiaguaba Beach. Given that it is an urban river, it suffers several environmental impacts along its course, since it receives industrial and domestic effluents. This research aimed to analyze the water quality of the Cocó River during the research period, which was from July to October of 2018. The CONAMA Resolution No. 357/2005 and CONAMA Resolution No. 274/2000 were used to perform a later comparison with the results obtained from the study. Points 1 and 2 are within the Cocó Ecological Park, and points 3, 4, 5, and 6 are located in the Sabiaguaba neighborhood. The last point is found at its mouth. The majority of the research results showed low rates regarding the pollution of this water body. Some parameters showed highly altered numbers in points 1, 2, and 6, and the microbiological analysis exceeded the legislation’s limits. As concluded, the studied section presents precarious sanitary quality as an urban water resource.
