Water Quality Parameters in Brazil

ABSTRACT

In recent years the quality of water and sewage treatment in Brazil is in evidence and widely discussed, due to the various cases of contamination by cyanobacteria and pathogens, giving prominence in this study Geosmina, ZikaVirus and COVID-19, that impact water bodies. The purpose of this is to debate the current legislation and regulatory agencies that classify water quality, interpreting criteria for the preservation of aquatic life, the conservation of the areas that surround the rivers and their possible consequences for human health. The methodology was based on the literary review on national and international sites, in public bodies and institutions, the IVA – Aquatic Life Preservation Index (CETESB, 2017a/b) was defined as strategic for the preservation of the aquatic ecosystem and providing drinking water for human consumption. It was found as results: The diversity of 60 controlling agencies across the country discourage a centrality of data and control. ANA (2021) is only responsible for analyzing pH, dissolved oxygen, conductivity and temperature, without control devices to avoid contamination, and highlighted CEDAE in repeated episodes of geosmina contamination in the Guandu River, which prove eutrophication of this body of water and the poor quality of the water supplied to the consumer, unpleasant odor and taste. © 2021, Universidade Federal de Pernambuco.
