What Are the Sources of Water?

A crucial component of our life is water. How often do we consider the water source for drinking, cooking, bathing, and other household chores? 

Where is the source of our water?

There is a lot of water everywhere around us, but it is not fresh water and is not fit for human consumption, according to the geography of the Earth. Surface water and groundwater are the two main sources of water.

While groundwater is found beneath the land’s surface and moves through and fills fissures in the rocks, surface water is found in lakes, rivers, and reservoirs. An aquifer must be pumped to the planet’s surface to use groundwater. 

Here are the two primary water sources: groundwater and surface water. 


Any water source located below the soil layer is referred to as groundwater. These are the water sources that you essentially can’t see or easily access. The soil itself, as well as the spaces between rocks and other objects, may contain groundwater.

Only 30% of this meager amount is found as groundwater, with most settlements getting their water from subterranean aquifers or rock formations that may store enormous amounts of freshwater. Overuse, pollution, and tainted seawater pose threats to this priceless resource. 

Since well water is groundwater, it may undergo some sort of treatment before it gets to your tap.

The hydrologic cycle

The hydrologic cycle is a natural process in which water constantly moves, propelled by gravity and the energy from sunshine. Ocean water evaporates, holding temporarily as vapor in the atmosphere before falling back to Earth’s surface as precipitation.

Aquifers are vast porous soil and rock layers that store groundwater, slowly seeping down from the Earth’s surface. Groundwater moves slowly and steadily through the aquifer under the force of gravity.

It appears in springs and streams in low locations. Both groundwater and surface water eventually returns to the ocean, where evaporation renews the atmospheric water vapor supply. The moist air is carried over land by winds, precipitation happens, and the hydrologic cycle is completed.

Surface water

Any above-ground body of water, such as rivers, lakes, ponds, and seas, can serve as a surface water source. Surface water availability is mostly influenced by rainfall. Surface water supplies will fluctuate greatly between years and between wet and dry seasons when rainfall is scarce.

Hydroelectricity is produced by surface-water structures like dams and reservoirs, providing water for domestic, commercial, and industrial needs.

Although on a much smaller scale, rainwater is a crucial water source.

It has arguably the greatest natural water source. The majority of the planet’s surface water is salt water. Hence it is not suitable for drinking. Precipitation, springs, and ice melting from glaciers and higher elevations provide surface water.

Why is water essential to the human body?

More benefits to drinking water than simply quenching thirst. It is necessary to keep your body operating properly.

The majority of the major systems in your body rely on water to function and survive. About 60% of your body weight is made up of water.

Water is a critical nutrient for our body and is crucial for the following processes:

  • Lubricates joints
  • Controlling body temperature
  • Moisturizes the tissues in the eyes, nose, and mouth
  • Removes toxins and other waste from the body
  • Oxygen and nutrients are transported to various cells, tissues, and organs
  • Clearing away waste products lessens the strain on the kidneys and liver
  • Makes minerals and nutrients available to your body by dissolving them

Why is water resource vital?

The simplest definition of life is water. Water is necessary for every life on Earth to live.

Water and water resources are crucial for all living things to remain in a state of sufficient food production and a productive environment. A growing population, rising demands from industry and agriculture, and the deteriorating effects of climate change all pose serious threats to water availability today.
