摘  要:The Rocha River is a receptor to receive wastewater from household,hospital and industry,from where contaminants are transported in the river,affecting biodiversity and the ecosystem of the area.In this paper we estimated the maximum transport of total chromium and chloride anion by applying the analytical model of Ogata&Banks(1961),and the results obtained are grouped into three zones:Contaminated,transition,and uncontaminated.The analytical model was applied with 13 samples collected from the river piezometers installed near Rocha,where they are arranged in two lines,i.e.RH-1 to RH-6 as the first line and RH-9 to RH-12 as the second line.The total chromium concentrations range from 0.16 mg/L(RH-1)and 0.11 mg/L(RH-9)at the closest points to Rocha River,to 0.13 mg/L(RH-7)and 0.03 mg/L(RH-12)at the most remote points to the river.The advance of the pollutants does not exceed 50 meters with respect to the axis of the Rocha River.
