Question

Define an aquifer.

Answer 1

Hint: Municipal, irrigation, and water supplies for industries are provided through large wells. Multiple wells for one facility source are called wellfields. Using ${{H}_{2}}O$ from deep, confined aquifers provides more protection from surface water contamination.

Complete Solution :
- An aquifer could be a body of rock and/or sediment that holds groundwater. Confined aquifers have a layer of impenetrable rock or clay above them, while unconfined aquifers are present below a permeable layer of soil.
- The definition of an aquifer could be a natural well created by an underground rock or other formation. An example of an aquifer is the Great Artesian Basin. It is an underground layer composed of permeable rock, sediment, or soil that yields water.
- An aquifer could be a body of porous rock or sediment saturated with groundwater. Groundwater enters through an aquifer as precipitation seeps through the soil. It can pass through the aquifer and resurface through springs and wells.
- When a water-bearing rock readily transmits water to wells and is derived, it's called an aquifer. Wells will be drilled into the aquifers and water is often pumped out. Precipitation eventually adds water (into the porous rocks of the aquifer.
There are mainly four forms of aquifers. They are classified as (1) Unconfined Aquifer (2) Perched Aquifer (3) Confined Aquifer (4) Leaky Aquifer or Semi-Confined Aquifer.

Note: Unlike surface water, which is usually found in the northern and eastern parts of the state, aquifers are cosmopolitan throughout California. Additionally, they're also often found in places where freshwater is most needed, for example, found within the Central Valley and in parts of Los Angeles.
