A well pumps at a constant rate of 15 L/s in an unconfined coastal aquifer. The aquifer is 40 m thick and has a hydraulic conductivity of 68 m/day. An initial horizontal saltwater interface lies 14 m below the top of the well screen. If the local rise of the interface below the well is monitored continuously, when should the pumping be stopped before the quality of water is affected?

A well pumps at a constant rate of 15 L/s in
an unconfined coastal aquifer. The aquifer
is 40 m thick and has a hydraulic
conductivity of 68 m/day. An initial
horizontal saltwater interface lies 14 m
below the top of the well screen. If the
local rise of the interface below the well is
monitored continuously, when should the
pumping be stopped before the quality of
water is affected?
