O presente estudo teve como objetivo analisar e diagnosticar a qualidade das águas do córrego Sucuri, localizado no município de Caçu-Goiás. Para tanto, delimitou-se como área de estudo a bacia do córrego Sucuri, que está inserida na bacia do reservatório da Usina Hidrelétrica Barra dos Coqueiro. Foram definidos cinco pontos de amostragem no curso d'água e as coletas foram realizadas em quatros períodos distintos. Parâmetros analisados: potencial Hidrogeniônico (pH), oxigênio dissolvido (OD), demanda bioquímica de oxigênio (DBO), temperatura da água (T), condutividade elétrica (CE), total de sólidos dissolvidos (TSD), salinidade (NaCl), coliformes termotolerantes (CT) e fósforo total (P). A metodologia de análise da água seguiu a proposta do Standard Methods for the Examination of Water and Wastewater e Resolução CONAMA (2005). De acordo com os dados avaliados, a não conformidade da água do córrego Sucuri para classe 1 é afetada pela CE, P e CT, sendo esse curso d'água classificado como de classes 2 e 3. Há correlações muito fortes entre os parâmetros TDS, CE e NaCl e estão relacionadas as características física e geológicas da bacia e tipos de solo.Downloads
