Methods for Finding Underground Water and Water Tables

The importance of groundwater as an important national resource is nearly impossible to refute by anyone. Ever since the world has made, people all over the world have been making great use of it for various purposes. At present, groundwater is being used by more than half of the total U.S. population and 99% of the population living in rural areas. This significant component of the water cycle helps grow our food and plays a pivotal role in many industrial processes.

Considering the growing and vital importance of water, as well as their shortage in mind, we have to endeavor to improve the preservation of these essential resources. We need to understand the science behind groundwater to dig out groundwater and use it for drinking and irrigation purposes.

The practice of locating groundwater is not new; it is an old-age practice. It is said to be started with Moses or even earlier. In the Sinai desert, Moses used to find groundwater using his divining rod. People, at that time, used to dig small depths, in the river alluvium, and gather the water coming through seepage, and used that water to drink or carry down everyday chores. The practice is popular, even today.

At present, we have a number of modern methods for water detection that made it possible to locate aquifers with more precision. Some of the methods are mentioned below:

1.    Geophysical Method

A geophysical method is a technical method to find water within the ground. Compared to various other methods, this method doesn’t require drilling a hole while exploring for and locating water in hard crystalline rock areas. The geophysical method aims to evaluate a specific physical property of the rock or residue such as the electrical resistance or conductance, compactness, and magnetic properties of the land. However, the method is limited when it comes to locating an aquifer.

2.    The Isotope Method

The isotope method is one effective method to find well water. It helps trace the water flow, estimate the age of the groundwater, and detect or assess intrusions. The method is proven to be the most promising method when used with the physical models describing the water flow. It is efficient in evaluating the size, volume, quality, and sustainability of groundwater, as well.

3.    Proton Magnetic Resonance (PMR)

PMR, also known as Proton Magnetic Resonance, is a direct water detection method, which transmits electric currents into the earth, and evaluates the motions released by the nuclei of hydrogen atoms in the molecules of water. Proton magnetometers is an important instrument used in PMR, which allows to assess electromagnetic fields. This method is as effective as the isotope method when it comes to interpreting the recordings, and the amount of water present in the soil. 

The Last Word!

There’s a whole science that works behind locating the water present within the earth. When it comes to water detection, we need to locate it precisely and assess its quality since groundwater is good-quality water that is buried at significant depths. It should be done with the utmost care and precision, by means of appropriate methods, to dig wells in the best possible places. A comprehensive understanding and strong grip on the techniques mentioned above will help avoid failures.
