which statements about wells are true? check all that apply. wells bring groundwater from the unsaturated zone to the surface of the water. wells need to be drilled below the water table. if water is pumped from a well too quickly, the well may run dry. water from wells is generally not safe to drink. water gushes from artesian wells due to pressure.

Answer

Brief Explanations:

  • Wells access groundwater from the saturated zone, not the unsaturated zone, so the first statement is false.
  • Wells must be drilled below the water - table to access water, so the second statement is true.
  • Over - pumping can cause a well to run dry as the water recharge rate is slower than the pumping rate, so the third statement is true.
  • Water from wells can be safe to drink if properly treated and the source is uncontaminated, so the fourth statement is false.
  • Artesian wells have water that gushes out due to pressure in a confined aquifer, so the fifth statement is true.

Answer:

Wells need to be drilled below the water table. If water is pumped from a well too quickly, the well may run dry. Water gushes from artesian wells due to pressure.
