Poorly planned drilling can result in losses and frustration. Therefore, before opening an artesian well, it is essential to find out if there is a water vein in the area.
Digging an artesian well is not just digging a hole. The decision requires care, planning and information. Not all land has water, and a mistake can be costly. Therefore, before starting drilling, it is essential to check if there is any “water vein” or accessible water table.
The good news is that there are ways to do this. Some are based on science, others on practical observation. There are also traditional methods still used in various regions of Brazil. Combining all of these can greatly increase your chances of success.
Companies that analyze soil
There are specialized companies that offer soil analysis services for those who want to drill an artesian well.
- American startup carries out the first industrial operation of an electric reactor and produces tons of steel with technology that promises to reduce emissions in the steel industry
- NASA captures Curiosity rover exploring the surface of a huge crater
- Researchers at the University of East London have built a school using sugarcane bagasse blocks as raw material
- UK plans $62 million geoengineering project to block sunlight and combat global warming
These professionals use equipment such as geophysical probes, which allow the identification of water veins and the estimation of the depth of groundwater.
The analysis also considers other factors, such as soil permeability and the geological characteristics of the area. All of this helps to assess the region's water potential.
The cost of these services varies greatly. It depends on the technology used, the area assessed and the complexity of the land.
Therefore, it is recommended to ask for personalized quotes and, above all, check whether the company is registered with the responsible bodies.
Signs of nature — what the terrain can show
Observing the surrounding landscape can reveal a lot. In many cases, nature itself provides clues about the presence of groundwater.
Areas with greener vegetation, places where grass grows faster, or land that takes longer to dry after rain can indicate the presence of moisture underground. These are simple but valuable clues.
Other important signs include the existence of natural springs, old abandoned wells or even depressions where small temporary lakes form.
In plantations, for example, it can be noted that certain crops, such as corn and wheat, grow better in areas with more access to water. These locations are usually closer to underground veins.
Modern equipment — detectors and measurements
Current technology also offers interesting features for those who want to increase their chances of finding water. One of the most common methods is the use of electromagnetic detectors.
These devices measure the electrical conductivity of soil. Since water conducts electricity better than dry soil, the equipment can identify regions with greater humidity.
Although it does not indicate the exact depth of the water, it helps direct the excavations to the most promising points.
Another, simpler resource is the trench test. It consists of digging a shallow hole and observing whether the soil is moist.
It is a cheap and easy-to-use technique, but it requires attention. Before digging, it is necessary to consult the local city hall.
This prevents accidents with pipes, underground wiring or other buried infrastructure. Municipal bodies usually provide maps of the network. underground of the city.
Radiesthesia — a popular practice, but without scientific proof
Radiesthesia is an ancient practice that still generates debate, especially among scientists. It involves the use of rods in Y shape ou pendulums, used by people who claim to have the ability to find groundwater.
These “sensitives” are still hired in several regions of the interior, including by city halls. In rural communities in states such as Pernambuco, Ceará and Bahia, it is common for families to seek out these practitioners before digging wells.
Many say the results are positive. Some even charge for the service. Even without scientific basis, many residents believe in radiesthesia.
Some say it works through “sensitivity” or “gift.” Others claim that, even without proof, the technique helps to choose spots with a greater chance of finding water — especially in places where knowledge of the soil is passed down from generation to generation.
Although there is no scientific evidence, radiesthesia continues to be used by those who trust traditional methods or have already had good experiences with the practice. However, for those seeking more security and precision, the best option is still to trust in science.
Hydrologists — the experts on the subject
Anyone who really wants to bet on precision can hire a hydrologist. This professional specializes in the study of groundwater and can perform a detailed technical analysis of the site.
The hydrologist considers aspects such as topography, type of rock, vegetation and can use imaging techniques to detect water tables.
Therefore, the risk of investing in drilling that will not yield results is much lower.
Conversations with locals — wisdom from those in the know
Often, talking to those who have lived in the area for a long time can be more helpful than it seems. Longtime residents, experienced farmers, and government officials are often very familiar with the geography of the area.
They know where artesian wells once existed, where there was water in the past, or where the soil is drier. This type of information, when combined with technical data and visual observation, helps to create a more complete picture of the area.
In other words: before investing in excavations, it is worth investing some time in listening to stories and reports from those who already live there.
Planning is the best way
Finding water underground is possible, but it requires patience, attention and preparation. There is no single, foolproof method.
The ideal is cross information: use scientific data, observe nature, talk to neighbors and, if you want, even resort to traditional methods.
Each terrain is unique. Therefore, the secret lies in combining techniques. With good planning, the chances of finding water increase — and the risks decrease.
Digging an artesian well can bring many benefits, such as greater autonomy in supply, cost reduction and water security.
But this only makes sense if the water is actually there. And to be sure, it's worth taking the right steps.
Many technical improprieties
This is quackery. A subject without scientific meaning.
Are you serious???? You are promoting radiesthesia as a science???? You have crossed the line.
