When you are planning to drill a water well at your property, the first and most important thing to consider is the drilling site. You have to make sure that the site you select has a huge water potential. A well driller can help you do this. State licensed drillers have the ground knowledge and experience. They can give a more accurate estimate as compared to water witches. In this article, we will study how well drillers find water for drilling a well?
How do Hydrogeologists (Well Drillers) locate Water?
When a state gives licenses to a well driller, it makes sure that the individual/company has the ground knowledge, required machinery, and the personnel to drill water wells. Well drillers start the process by checking out the geological maps. They also have the experience of drilling hundreds of wells in their area and are aware of the underground dynamics. The geological maps tell us about the type, quality, and quantity of rocks underneath the property, and from this, the drillers can guess which place is best for drilling the well.
The specific shape, formation, and physical appearance of the rocks tell the drillers that how much water it contains. It also tells an estimate on how much time/effort and money will be needed to drill a hole at that particular place.
The topography and formation of the rocks are also used to identify water flow, refilling capacity, recovery rate, and discharge points. The formation does not tell anything about the water quality. Using this information, a well driller can conclude which place is suitable for drilling a well and which must be avoided.
Neighborhood well drillers have knowledge of the area and results of the recent drilling activities. Some well drillers also keep a record of all the wells drilled in the vicinity, how much water was found, and the water quality. This information helps in calculating the probability of drilling success.
With the help of the knowledge and experience, a well driller will be able to find the characteristics of your land and the rocks underneath it, previous drilling results, and the flow of underground water movement.
How do Water Witches find Water?
Water witching, dowsing, and divining are the different names given to the ancient practice of finding water for drilling a well. Some people practice this technique and try to find out the water underneath. These people use a forked stick, pendulum, or a pair of L-shaped rods that move in a certain direction to indicate water. The reason behind this concept is that the area containing underground water has some forces, and the tools respond to these forces.
