Resumo: The objective of the work was to assess the water quality of the stream Cacau sub-basin over the years in the urban area of the city of Imperatriz-MA (Amazon portal), aiming to subsidize instruments for the management of urban water resources. In this study, aspects of human interference in the aquatic ecosystem were considered. The interferences in the water quality were evaluated by the following variables: pH, Redox potential, Chlorides, Alkalinity, Acidity, Dissolved oxygen, Total nitrogen, Total phosphorus, Temperature, Electrical conductivity, Turbidity, total solids, Particulate matter in suspension, Total and coliforms Thermotolerant coliforms, with the parameters created a database on the real situation of the water body. After assessing the physical and chemical characteristics of the stream waters, the Water Quality Index was calculated using the Basic method (IQAb) and the Person correlation coefficient. Riacho Cacau obtained water quality indexes ranging from good to excellent in the years 2015-2016 when compared to the values ​​2018-2019, in which 50% of the samples obtained Good IQA, 25% Excellent IQA and 25% Pleasant.

En este estudio se consideraron aspectos de la interferencia humana en el ecosistema acuático. Las interferencias en la calidad del agua se evaluaron mediante las siguientes variables: pH, Potencial redox, Cloruros, Alcalinidad, Acidez, Oxígeno disuelto, Nitrógeno total, Fósforo total, Temperatura, Conductividad eléctrica, Turbidez, Sólidos totales, Partículas en suspensión, Totales y coliformes Coliformes termotolerantes, con los parámetros se creó una base de datos sobre la situación real del cuerpo de agua. Luego de evaluar las características físicas y químicas de las aguas de los arroyos, se calculó el Índice de Calidad del Agua utilizando el método Básico (IQAb) y el coeficiente de correlación de Person. Riacho Cacau obtuvo índices de calidad del agua que van de buena a excelente en los años 2015-2016 al compararlos con los valores 2018-2019, en los que el 50% de las muestras obtuvieron Buen IQA, 25% Excelente IQA y 25% Agradable.O trabalho teve como objetivo a avaliação da qualidade da água da sub-bacia do Riacho Cacau ao logo dos anos na área urbana da cidade de Imperatriz-MA (portal da Amazônia), visando subsidiar instrumentos de gestão dos recursos hídricos urbanos. Considerou-se neste estudo os aspectos de interferência humana no ecossistema aquático. As interferências na qualidade da água foram avaliadas pelas seguintes variáveis: pH, Potencial redox, Cloretos, Alcalinidade, Acidez, Oxigênio dissolvido, Nitrogênio total, Fósforo total, Temperatura, Condutividade elétrica, Turbidez, sólidos totais, Material particulado em suspensão, Coliformes totais e Coliformes termotolerantes, com os parâmetros criou um banco de dados sobre a real situação do corpo hídrico. Após a avalição das características físico-químicas das águas do riacho foi aplicado o calculado do Índice de Qualidade da Água utilizando o método de Báscaran (IQAb) e  o coefiente de correlação Person. O Riacho Cacau obteve índices de qualidade de água variado de bom para excelente nos anos 2015-2016 quando comparados com os valores 2018-2019, em que 50% das amostras obtiveram IQA Bom, 25% IQA Excelente e 25% Agradável.Research, Society and Development2021-02-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1263110.33448/rsd-v10i2.12631Research, Society and Development; Vol. 10 No. 2; e45510212631Research, Society and Development; Vol. 10 Núm. 2; e45510212631Research, Society and Development; v. 10 n. 2; e455102126312525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/12631/11479Copyright (c) 2021 Marcos Jean Araújo de Sousa; Mariane Furtado Gonçalves; Jorge Diniz de Oliveira; Claudia Karen Silva Lopeshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSousa, Marcos Jean Araújo de Gonçalves, Mariane Furtado Oliveira, Jorge Diniz de Lopes, Claudia Karen Silva 2021-03-02T09:32:39Zoai:ojs.pkp.sfu.ca:article/12631Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:34:09.194100Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
