Aquifers

An aquifer is a body of porous rock or sediment saturated with groundwater. Groundwater enters an aquifer as precipitation seeps through the soil. It can move through the aquifer and resurface through springs and wells.

An aquifer is a body of rock and/or sediment that holds groundwater. Groundwater is the word used to describe precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground.

There are two general types of aquifers: confined and unconfined. Confined aquifers have a layer of impenetrable rock or clay above them, while unconfined aquifers lie below a permeable layer of soil.

Many different types of sediments and rocks can form aquifers, including gravel, sandstone, conglomerates, and fractured limestone. Aquifers are sometimes categorized according to the type of rock or sediments of which they are composed.

A common misconception about aquifers is that they are underground rivers or lakes. While groundwater can seep into or out of aquifers due to their porous nature, it cannot move fast enough to flow like a river. The rate at which groundwater moves through an aquifer varies depending on the rock’s permeability.

Much of the water we use for domestic, industrial, or agricultural purposes is groundwater. Most groundwater, including a significant amount of our drinking water, comes from aquifers. In order to access this water, a well must be created by drilling a hole that reaches the aquifer. While wells are manmade points of discharge for aquifers, they also discharge naturally at springs and in wetlands.

Groundwater can become depleted if we use it at a faster rate than it can replenish itself. The replenishment of aquifers by precipitation is called recharging. Depletion of aquifers has increased primarily due to expanding agricultural irrigation. Groundwater can become contaminated when an excessive amount of pesticides and herbicides are sprayed on agricultural fields. septic tanks leak, or landfills are improperly lined or managed and toxic materials seep through the soil into the aquifer.

Aquifers naturally filter groundwater by forcing it to pass through small pores and between sediments, which helps to remove substances from the water. This natural filtration process, however, may not be enough to remove all of the contaminants.

Groundwater and aquifers

A hole dug at the beach illustrates the concept of how the ground, if it is permeable enough, can hold water. ​​​​​​​The upper surface of this zone of saturation is called the water table.

Groundwater is one of our most valuable resources—even though you probably never see it or even realize it is there.

Have you ever dug a hole at the beach and watched as it partially filled with water from the underlying sand? This is a great way to illustrate the concept of how the ground, if it is permeable enough, can hold water but still stay solid. The upper surface of this water-filled area, or “zone of saturation”, is called the water table.

The saturated area beneath the water table is called an aquifer, and aquifers are huge storehouses of water. In our sand hole example, you have essentially dug a “well” that exposes the water table, with an aquifer beneath it. At the beach, the level of the water table is always at the same level as the ocean, which is just below the surface of the beach.

As you may read, most of the void spaces in the rocks below the water table are filled with water. These rocks have different porosity and permeability characteristics, which means that water does not move around the same way in all rocks below ground.

When a water-bearing rock readily transmits water to wells and springs, it is called an aquifer. Wells can be drilled into the aquifers and water can be pumped out. Precipitation eventually adds water into the porous rock of the aquifer. The rate of recharge is not the same for all aquifers, though, and that must be considered when pumping water from a well. Pumping too much water too fast draws down the water in the aquifer and eventually causes a well to yield less and less water and even run dry. In fact, pumping your well too much can even cause your neighbor’s well to run dry if you both are pumping from the same aquifer.

How Ground Water Occurs

It is difficult to visualize water underground. Some people believe that ground water collects in underground lakes or flows in underground rivers. In fact, ground water is simply the subsurface water that fully saturates pores or cracks in soils and rocks.

Ground water is replenished by precipitation and, depending on the local climate and geology, is unevenly distributed in both quantity and quality. When rain falls or snow melts, some of the water evaporates, some is transpired by plants, some flows overland and collects in streams, and some infiltrates into the pores or cracks of the soil and rocks.

The first water that enters the soil replaces water that has been evaporated or used by plants during a preceding dry period. Between the land surface and the aquifer water is a zone that hydrologists call the unsaturated zone. In this unsaturated zone, there usually is at least a little water, mostly in smaller openings of the soil and rock; the larger openings usually contain air instead of water.

After a significant rain, the zone may be almost saturated; after a long dry spell, it may be almost dry. Some water is held in the unsaturated zone by molecular attraction, and it will not flow toward or enter a well. Similar forces hold enough water in a wet towel to make it feel damp after it has stopped dripping.

Some Questions what process leads to water entering an aquifer:

What happens when contaminants find their way into an aquifer?

When contaminants find their way into an aquifer, there will be a need to purify the water again. There are filters built into this type of system to prevent contaminants from entering the drinking water.

Which is better for drinking water from an aquifer or an artesian aquifer?

from an aquifer

Water that enters an aquifer?

Underground water enters an aquifer.

What is the process by which water enters earth to become groundwater?

aquifer

Can an aquifer hold water?

Of course it can, silly! An aquifer is for aqua, water.

How do you write a sentence with the word aquifer?

(An aquifer is an underground strata containing water.) The increase in agriculture in the valley depleted much of the water in the aquifer. An aquifer can provide water for land that is not near a body of water.

How does an aquifer refill?

For an aquifer to be refilled it either needs to have permeable beds above it so water can percolate down to it or it needs to have recharge zones in which the same percolation process can occur

How can people obtain water from an aquifer?

People can obtain water from an aquifer by drilling a well below the water table.

Is aquifer the water bearing layer of the earth?

Yes, an aquifer is one of the water bearing layers.

What is the process of liquid water changing into the water vapor and entering the atmosphere called?

evaporation

Why is aquifer important?

An aquifer is important because it is a major source of water for irrigation and wells. Depleting an aquifer can cause serious water shortages for many years.

What is an aquifer why is it so important?

An aquifer is an underground fresh water source.

What is the name of Memphis’s aquifer?

Memphis Sand aquifer and some water comes from the Fort Pillow Sand aquifer.

What is an abstraction?

An abstraction is a process of making something abstract – withdrawal from senses, or of removing water from a river, lake, or aquifer.

How is an aquifer different from an aquitard?

An aquifer is different from an aquitard because an aquifer allows water to pass through whereas an aquitard does not.

Which is not a kind of surface water pond stream aquifer or runoff?

An aquifer is underground.

What the diffrent between aquifer and water table?

An aquifer has natural pressure pushing the water upwards towards the surface.

What is the difference between an aquifer and an aquitard?

An aquifer is as a body of rocks, that water can easily move through. An aquitard is a body of land that restricts water flow from one aquifer to another.

Rainfall percolating down to the aquifer from its catchment area.

What is typical source of well water?

aquifer is the correct answer

What determines how much water an aquifer can hold?

An aquifer refers to a body of permeable rock that can contain or transmit groundwater. The factor that determines how much water an aquifer can hold is the composition of its surrounding bedrock.

How do you find out how healthy your aquifer is?

You can find out how healthy your aquifer is by testing the water for microbes. If the water contains microbes, boil it before drinking it.
