What Is the Definition of Groundwater Pollution?
Have you ever wondered where the majority of our drinking water comes from? If so, the answer is simple: approximately 50% of our population receives drinking water directly from groundwater. This is especially true for residents who live in rural areas. Although it is one of our primary water sources, many are unsure what groundwater is.
What is groundwater?
Groundwater is defined as the water that fills the spaces among soil bits and ruptured rocks underneath the earth’s surface. Groundwater can move through aquifers smoothly. An aquifer is a body of saturated rock through which water can easily move.
However, it must be penetrable and porous for groundwater to move quickly through aquifers. Some rocks that are porous enough for water to flow through them are sandstone, conglomerate, cracked limestone, and gravel. Water can move through aquifers at different speeds. The speeds at which water moves through these depend on the space between the soil and the aquifer. The larger the space, the faster the water can travel through. If the space between the soil and the aquifer is small, the water may have difficulty reaching its final destination.
Groundwater can be discovered almost everywhere. The water table plays a significant role in groundwater migration because it can become too deep or shallow, causing the groundwater to rise or fall throughout the migration process.
During migration, rain or snow melts and percolates deep into the ground’s fractures, reloading the groundwater. The more rain and snow a specific area receives, the easier it is for the groundwater to refill and the entire process to begin again.
Therefore, some areas worldwide have a water shortage because groundwater is used faster than naturally refilled. Another factor is groundwater pollution, which occurs when pollutants enter the groundwater supply and contaminate the water.
How is groundwater formed?
If the process begins underground, you may wonder precisely how groundwater is formed and how we use it for drinking or daily activities. The answer is quite simple: aquifers’ water comes to the surface through natural springs, lakes, and streams. However, drilling a well directly into an aquifer can naturally extract it from the ground.
If the well is positioned anywhere other than directly over an aquifer, it can go dry and not receive the proper amount of water. Some wells, known as artesian wells, do not need a pump to bring water to the surface. Instead, the natural pressure caused by the well will naturally bring the water to ground levels.
Groundwater is found in lakes, rivers, and streams, whereas surface water remains in the surface cavity. Meanwhile, groundwater needs to be sought after. Nevertheless, both water sources can be polluted by multiple factors.
