A slow leak from an underground storage tank has contaminated both the soil and the groundwater as shown below. Soils contaminated below the tank is in the shape of a rectangular prism as shown in the figure. The contaminated groundwater is in the soils, in the shape of a rectangular pyramid as shown in the figure. Soil density: 1800 Kg/m3 Porosity: 0.25 Contaminant concentration in soils: 950 mg/Kg Contaminant concentration in groundwater: 45 mg/L Amount contaminant present in the soils below the groundwater is most nearly (kg): W =5m D-2 m D 10m W=8m D-10m Groundwater direction
