Here is How does groundwater form

Water

Water is a chemical substance composed of hydrogen and oxygen elements and is present on the planet in its solid, liquid, and gaseous states, and it is also one of the most abundant and basic substances in nature, and water is a liquid that has no taste, color or smell and is distinguished by its important ability to dissolve many other substances, and in, In fact, the versatility of water as a solvent is necessary for living organisms, and it is believed that the beginnings of life originated in the aqueous solutions of the world’s oceans, and water is found on the surface of the earth in a liquid form under natural conditions, but it easily turns into steam and this allows it to be transported through the atmosphere from the oceans to the interior regions where it condenses It feeds plant and animal life as rain, and this article answers the question “How does groundwater form?”

water cycle in nature

Before answering the question “How does groundwater form”, one must know the water cycle in nature, which is scientifically known as the hydrological cycle, which refers to the continuous exchange of water within the hydrosphere between the atmosphere and water in the soil, surface water, groundwater, and plants. Permanent through all these areas in the water cycle which includes the following crossovers:

  • Evaporation from oceans and other bodies of water into the air, and transpiration from land plants and animals into the air.
  • Precipitation from water vapor condensed in the air and falling onto land, oceans, and seas, forming surface water.
  • Surface runoff of water on the surface of the earth and usually reaches the seas, or it may seep into the ground to form groundwater.

How does groundwater form

Water is able to move underground through rocks and soil due to the pores in it, and these pores can be small in size, which is found inside particles of rocks or soil, or be a phrase About digging and fractures in rocks or cavities dissolved in limestone such as caves, and a common misconception about groundwater is that it exists as a large reservoir or an underground lake, but the truth is that groundwater fills the small spaces inside the rocks and soil just as water fills spaces in a sponge, During the recharging process, water is drawn to the ground by gravity through two areas, the upper zone called the aeration zone, which is the place where a mixture of water and air fills the pores, while below the aeration zone there is a zone of saturation where the pores are completely filled with water and the upper limit of the saturation zone is known. With groundwater and the saturated area is called the aquifer.

The importance of groundwater

After answering the question “How does groundwater form”, it is necessary to address its importance, as freshwater is one of the most important necessities for human life at the present time, and groundwater constitutes about 30 percent of the fresh water on the surface of the earth, and due to the difficulty of seeing groundwater easily It is often not appreciated or preserved adequately, and groundwater is a vital and important source of freshwater around the world. In fact, groundwater accounts for about 20% of all water used in the United States. Nevertheless, groundwater is highly vulnerable to pollution that comes. From multiple sources, the most important sources of this pollution will be discussed in the next paragraph.

Groundwater pollution

The layers of soil and stones in the ground may seem like solid protective barriers that prevent pollutants from entering the groundwater, but there are at least five ways in which the groundwater supplies in the ground can be contaminated:

  • Sources of human waste: As the geological survey notes, groundwater pollution through groundwater sources is usually a result of negligence or ignorance, as wastewater leaking from septic tanks into neighboring areas can contaminate the groundwater with viruses, bacteria, and nitrates, and nitrates are among the most pollutants of water sources. Aquifers are common in the United States.
  • Agricultural pesticides and pollutants: Agricultural activities may provide people with the food they need for their lives, but it can also contaminate the groundwater supplies if containers that store livestock waste leak into groundwater stores, as well as the farmers’ use of a lot of chemical fertilizers or pesticides on the ground, pollutes groundwater sources Significantly.
  • Landfills: Thousands of landfills around the world help societies to manage their waste, and modern laws require the use of modern landfills that use many means of protection to prevent leakage, however, old landfills that do not have this protection can contribute to polluting groundwater sources significantly.
  • Landfills: Thousands of landfills around the world help societies to manage their waste, and modern laws require the use of modern landfills that use many means of protection to prevent leakage, however, old landfills that do not have this protection can contribute to polluting groundwater sources significantly.
  • Storage container leakage: Substances already underground can contribute to groundwater problems. If underground storage tanks containing chemicals, diesel, gasoline, or other hazardous liquids are corroded, the liquids inside them leak into the ground and can reach water sources. Subterranean.
