both the water table and the groundwater is at the top of the aquifer
The top of an aquifer is called the water table, which is the boundary between the unsaturated zone above and the saturated zone below. It represents the level at which the pore spaces in the rock or sediment are filled with water. The water table can fluctuate due to factors such as rainfall, pumping of groundwater, and geologic conditions.
Water under pressure in a confined aquifer is groundwater that is located between impermeable layers of rock or sediment and is under enough pressure that when a well is drilled into it, the water will rise above the top of the aquifer without the need for pumping. This type of aquifer is also known as an artesian aquifer.
Some of the largest aquifers in the US include the Ogallala Aquifer, the Edwards-Trinity Aquifer System, the Floridan Aquifer System, and the Great Basin Aquifer System. These aquifers are crucial sources of groundwater for drinking water and irrigation in their respective regions.
The top of the saturated zone of groundwater is called the water table. It represents the boundary between the saturated and unsaturated zones in the ground.
