A zone of earth material capable of supplying groundwater at a useful rater from a well 4. What is an aquitard? a. A zone of earth material that will hold water but not transmit it fast enough to be pumped from a well 5. What do aquitards forms? a. Confining layer through which little water moves 6. What is an unconfined aquifer? no confining layer restricting the upper surface of the saturated zone 7. What is a confined aquifer? a. A confined layer is present 8. What is groundwater recharge? a. Any process that adds water to an aquifer (can be natural or human induced) 9. What is groundwater discharge? a. Any process that removes water from an aquifer (can be natural (springs) or human induced ( pumping water from a well)) 10. What is a cone of depression? a. Forms in the water table when water is pumped from a well 11. What is the water table? a. The upper limit of the zone of saturation (important in: predicting the productivity of wells, explaining the changes in flow of springs and streams; accounting for fluctuations in the levels of lakes 12.
