No, impermeable rock is the layer of rock that water CAN'T pass.
impermeable
Water bearing layer of earth is water table.
In some ground formations there is an impermeable layer which holds the water beneath it under pressure. In such a case where a well penetrates the impermeable layer, the water rises through the upper layers of the ground and even above ground-surface level
a. at the top of the zone of saturation
Water that does not percolate (move down through the soil) either is retained above the impermeable layer or becomes surface runoff.
No! It's called artesian if it IS under an impermeable layer, but just surface or ground water without it.
It is a layer that cannot be penetrated. Typically it refers to penetration by water, though it may sometimes refer to air. If water cannot permeate through a layer, that layer is impermeable.
Its located above layers of impermeable underground rocks. At or below the water table.

Impermeable means that stuff can't go through it. Wax is impermeable to water. Paper towels are not. Glass is impermeable to air. Mesh cloth is not. Some things are impermeable to one thing but not another. Clear plastic is impermeable to water and air, but not light. Lead metal is impermeable to x-rays, but not heat. Which layer is impermeable depends on what it is impermeable to.
The water stays there and forms a water table, like when you dig down in sand and reach water.
