Problem 2. At a site you are evaluating, chloroform (CHCI3) contamination is detected in a 300 ft?circular area, at a depth between 10 and 14 ft (see diagram below). If the soil in the contaminated area is saturated with a solution containing 435 µg chloroform per liter, and the soil has a porosity, Ø, of 0.38 (Ø = Vpoids/Vtotal), determine the following: i)What is the total volume of chloroform-contaminated soil? ii)What is the volume of the contaminant (i.e., the volume of the chloroform-containing solution)? iii)Assume the soil has a dry density of 1.30 g/cm^3. If 0.53 g of potassium permanganate (KMNO4) is required to treat each gram of chloroform, and the soil has a soil oxidant demand (SOD) of 0.16 g of KMNO4 per gram of soil, what is the minimum amount of KMNO4 (in kg) required for treatment? (Don't apply a safety factor here).
