Human action impact on water quality of Juturnaiba Dam - Silva Jardim, RJ

Abstract

The Juturnaiba Dam, located between the municipalities of Silva Jardim and Araruama, is the only fresh water source supplying the entire Lake District, State of Rio de Janeiro. The objective of this research was to evaluate the water quality of the Juturnaiba reservoir through physical, chemical and microbiological analyses conducted upstream and downstream in the rivers, comparing them in to identify its hydrodynamics. Six collections were made in six strategic points. The Capivari river was the tributary with greater restrictions on water quality. The river with better water quality was the São João River.
