A soil sample analysis indicates that the sorbed concentration of a contaminant in the aquifer is 2200 mg/kg. The linear groundwater velocity in the aquifer is about 7 cm/day. You undertook column experiments and established a kd of 0.176 L/kg under aquifer and groundwater chemistry conditions comparable to the field situation. You determined a porosity of the aquifer to be 0.3, while the soil density is 1800 kg/m³. Remember any relevant unit conversions which may be required. How far would you expect a dissolved plume of the contaminant to migrate in this aquifer, assuming that the spill occurred into the aquifer 180 days ago? Present your answer in cm to 2 decimal places. You do not need to include the unit with your answer. Answer:

A soil sample analysis indicates that the sorbed concentration of a contaminant in the aquifer is 2200 mg/kg. The linear groundwater velocity in
the aquifer is about 7 cm/day. You undertook column experiments and established a kd of 0.176 L/kg under aquifer and groundwater chemistry
conditions comparable to the field situation. You determined a porosity of the aquifer to be 0.3, while the soil density is 1800 kg/m³. Remember
any relevant unit conversions which may be required.
