An unconfined aquifer (porosity, n = 0.29) with a specific retention of 0.11 has an area of 130 miles². The water table dropped 5.88 ft during a recent drought. Compute the volume of water lost from the aquifer storage during the drought. Assume there was no appreciable recharge during the drought, and all other fluxes can be neglected.
