ABSTRACT
The objective of the present work was to investigate the quality of the water and the related ambient impacts in the basin of the High San Francisco. The following parameters of quality of the water had been evaluated: temperature of the water, pH (potential hidrogenionic), electric condutividade, dissolved oxygen (OD), chloride, lead, cadmium, zinc, iron and manganese, which had been gotten through to National Agency of Waters. In the region of the Hydroelectric of Three Marias and neighborhoods, the natural resources are compromised seriously and the quality of water is the worse one of the region. In this area the lead concentration reached maximums values of 30.1 mg L-1 and 56 mg L-1. Practical conservatives in the use and handling of the ground, urban planning, monitoring of the hydric quality, protection of the areas edges and implantation of projects of ambient education had been suggested, among others.Key-words: use and handling of the ground, hydroelectric of Three Marias, dissolved oxygen, hidrics pollution and ambient degradation.
