A) Any salty water in the aquifer will rise if the water table is lowered by pumping.
B) The water table must be 40 feet above sea level to keep the salty water in the aquifer below sea level.
C) Wells drilled below sea level will produce only saline water.
D) Pumping freshwater from one, large capacity well is much less likely to cause salty water to rise in the aquifer than pumping from several, widely spaced, smaller capacity wells.
Ans: A) Any salty water in the aquifer will rise if the water table is lowered by pumping.
