For some reason, a lined hazardous-waste landfill was located on top of a confined aquifer. Situated approximately 500 m away is a community water supply well which is pumped at a rate of 104 m³/d. If an earthquake occurs which splits open the liner and pollutes the aquifer, how much time is available to shut down the well and avoid withdrawing contaminated water? Assume the follow- ing aquifer characteristics are applicable: hydraulic conductivity = 50 m/d, porosity = 0.2, aquifer thickness = 5 m, and aquifer width = 50 m. (Courtesy of Jim Hunt.)

10.3. For some reason, a lined hazardous-waste landfill was located on top
of a confined aquifer. Situated approximately 500 m away is a
community water supply well which is pumped at a rate of 104
m³/d. If an earthquake occurs which splits open the liner and
pollutes the aquifer, how much time is available to shut down the
well and avoid withdrawing contaminated water? Assume the follow-
ing aquifer characteristics are applicable: hydraulic conductivity = 50
m/d, porosity = 0.2, aquifer thickness = 5 m, and aquifer width = 50
m. (Courtesy of Jim Hunt.)
