Resumo
The human action can change aspects of water quality restricting the possible uses of water
resources. It integrates the impacts of human activities, but in that regards it as a social concept.
The research shows the results of water quality with a view to understanding the geochemical
features and anthropic that alters the dynamics of the environment. Thus, the aim of this work
was to characterize the water quality of the Córrego Fundo, located in the region of Catalão and
Ouvidor, in the southeastern region of the State of Goiás. Was performed following the
determination of inorganic elements (Al, As, Ba, Cd, Pb, Co, Cu, Cr, Fe, Li, Mn, Ni, Ag e Zn)
in water and soil samples. These samples were collected during twelve months, from November
2008 until November - 2009, the physico-chemical tests were performed in Goiânia (GO) in
the Chemistry Laboratory of Superintendência de Geologia e Mineração - Agência de Fomento
do Estado de Goiás. The results of water samples were compared with those recommended by
CONAMA Resolution 357/2005 to check the water quality. The soil samples were used to
identify the occurrence of the elements in the water. Some water samples were inconsistent with
the Resolution for inorganic compounds, amoung them the aluminum (Al), iron (Fe),
phosphorus (P), manganese (Mn) and nitrogen (N) (Córrego Mata Preta); Al, lead (Pb), Fe, P,
Mn and N (Córrego Vargem Grande and Macaúba); Al, Pb, Fe, P, Mn e N (Córrego Garimpo
montante); Al, Pb, Fe, barium (Ba), P, Mn and N (Córrego Garimpo jusante) and Al, Pb, P and
N (Córrego Fundo). The results of analysis of water and soil from microbacia do Córrego Fundo
reflect the natural condition of water quality for the elements analyzed. Since the variability of
their concentration reflects the influence of seasonality (rainy and dry period) and of human
action. Therefore, we conclude that the water of microbacia do Córrego Fundo shouldn´t be fit
in class 2 of CONAMA Resolution 357/2005.
