Groundwater is the water present beneath Earth's surface in soil pore spaces and in the fractures of rock formations. A unit of rock or an unconsolidated deposit is called an aquiferwhen it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from and eventually flows to the surface naturally; natural discharge often occurs at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology.

Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, permafrost (frozen soil), immobile water in very low permeability bedrock, and deep geothermal or oil formation water. Groundwater is hypothesized to provide lubrication that can possibly influence the movement of faults. It is likely that much of Earth's subsurface contains some water, which may be mixed with other fluids in some instances. Groundwater may not be confined only to Earth. The formation of some of the landforms observed on Mars may have been influenced by groundwater. There is also evidence that liquid water may also exist in the subsurface of Jupiter's moon Europa.[1]

Groundwater is often cheaper, more convenient and less vulnerable to pollutionthan surface water. Therefore, it is commonly used for public water supplies. For example, groundwater provides the largest source of usable water storage in the United States, and California annually withdraws the largest amount of groundwater of all the states.[2]Underground reservoirs contain far more water than the capacity of all surface reservoirs and lakes in the US, including the Great Lakes. Many municipal water supplies are derived solely from groundwater.[3]

Polluted groundwater is less visible, but more difficult to clean up, than pollution in rivers and lakes. Groundwater pollution most often results from improper disposal of wastes on land. Major sources include industrial and household chemicals and garbage landfills, excessive fertilizers and pesticides used in agriculture, industrial waste lagoons, tailings and process wastewater from mines, industrial fracking, oil field brine pits, leaking underground oil storage tanks and pipelines, sewage sludge and septic systems.

Explanation:

I want to direct your attention toward the most difficult problems of our time: the wastage of water in my locality and other parts of the world.

Wasting water has become a problem in our neighborhood, as is the case in many parts of the world.

The people who own these wells let their sprinklers run for hours. The water waste is enormous as it runs down the street for several blocks.

Most people in my neighborhood obey all city ordinances on water usage, which is well appreciated by the community.

But just because a resident has a well, it does not give them the right to waste Earth’s precious gift.

People in villages also wash their car outside their house instead of going to the car wash, which leads to a lot of wasted water.

The other major cause of water wastage is farming. Farmers tend to open the water for the entire farm, which leads to water wastage.

Instead, they should use more effective methods like dip irrigation, which causes less water to waste.

Maybe we as a community should take heed of what’s being done about the problems in California and Colorado. To those states, water is valued like gold.

Water is a precious natural resource and it is irresponsible of residents and municipalities to waste it.

It’s a problem in many places, especially when it comes to wasting fresh, clean drinking water.

There are very serious effects from drinking contaminated water and unfortunately, many people around the world are faced with this problem every day.

It is high time to think and take timely action.

If we don’t take action now, maybe the next World War is going to be for the water.

I hope you will publish my letter so more people can be aware of the circumstances of water wastage.

Hope this will help you
