The present work was to evaluate the levels of water quality and its corrosive trend in "morichales" "Guaricongo" and "Caribbean" Heres municipality, Ciudad Bolivar, Bolivar State. Water samples were taken in each subwatershed study and at the confluence of the same. Physicochemical parameters were determined (temperature, pH, dissolved oxygen, total and dissolved solids, biochemical oxygen demand, chemical oxygen demand, total hardness, alkalinity, calcium, magnesium, nitrates, sulfates and chlorides). From this data rates of corrosion and scaling of Langelier (IL), Precipitation Potential (PPCC), m Ryznar (IR), Aggression (IA), Larson (RL), Singley, Buffer Capacity, Snoeyink were calculated. The results indicate that the waters of these "morichales" were slightly acidic and slightly hard water, indicative of an aggressive corrosive tendency, which was corroborated by the corrosion rates calculated by classifying these waters as unsaturated, preferably to dissolve the CaCO3 indicative of a corrosive nature.
