An industrial manufacturer owns a 12-in-diameter well that completely penetrates a 130-ft thick. unconfined aquifer with a coefficient of permeability of 0.00055 ft/sec. The well-pumping rate I 3.5 cfs, and the radius of influence is 500 feet Another industry plans to move into an adjacem property and install a well with the same characteristics. If the new well is 250 feet away, what i' the impact in additional drawdown at the existing well? (Hint: For unconfined aquifers, the drawdown equations are not linear. However, an estimate of the impact of the two identical pumped wells can be made by using the radius of influence as an observation well with zero drawdown. when both wells are in operation.)
