The Hydraulic Conductivity (K) of an unconfined aquifer is 2.5 x 10^-2 cm/s (0.025cm/s) there are two observation wells 5000 feet apart. Both wells penetrate the aquifer to the bottom at in impermeable aquitard. In one observation well (#1) the water table is at 30 feet, and the other well (#2) is at 20 feet above the bottom. What is the water table elevation at a point 1000 feet from observation well #1?.
