Groundwater Prospecting According To the Type of Rocks The Ground Water Survey Services is a conglomerate of research that allows us to locate underground aquifers where there is a certain amount of quality water. Groundwater prospecting methods The study of groundwater and groundwater prospecting may be issues of ignorance for a large number of people. But they are equally important in the development of daily life since, after all, water is the element that allows us to live. A person dies earlier due to lack of water than due to lack of food, hence the need to always have this energy source well guarded. Groundwater prospecting and groundwater study And it is that water constitutes more than 70 percent of the planet's surface. Therefore, it is good that we must take care of and exploit for our well-being, something that we will explain in this post. From the concept of physical prospecting to the methods to exploit and find the areas where water can be extracted. The survey for Geographic Information System (GIS) is defined as those physical and mathematical mechanisms used to explore the underground to search and study sites for users, such as oil, own groundwater, minerals, or coal substances, to which is reached after have made different observations from the surface of the Earth.
The following is to distinguish groundwater prospecting methods. The first of these is the geological method. We must look at the geological mapping of the place, as well as its structural and
stratigraphic characteristics to make profiles and geological cuts. It will give us an idea of the aquifers, their thickness, and other characteristics. The second method is the geophysicist, whose geophysical prospecting helps us to know how the materials are distributed in the subsoil and their nature. In this way, the exploration of groundwater and the study of groundwater is very important for the survival of our planet. Groundwater Prospecting In the study of groundwater, geological, and geophysical methods (such as Electrical Resistivity, gravimetric, and electromagnetic) are used to know the types of rocks. Study of groundwater according to the type of rocks Granitic rocks
They are little permeable and little porous. The density and weathering of the fracture decrease with depth. The uptake in troughs is by backhoes and in fractures by drilling.
Metamorphic rocks
They have fractures and are semipermeable (blackboards, quartzites, etc.).The boards can be clayey or sandstone. Pneumatic rotary perforations will make the captures.
Limestone rocks
They are limestones and dolomites. The pickups are by percussion, and it is done with a hammer in the background in the most charitable places. Rotopercussion will be performed in the densest areas.
Filoniana rocks
They are the diabasas. If this has many fractures, they act as drainage, and if they are poorly fractured, they are waterproofing, retaining the groundwater. A pneumatic rotary drilling machine makes the captures with a direct circulation on the dike and its sides.
Consolidated sedimentary rocks
They are detritic, with horizontal aquifers composed of permeable layers. They are performed with perforations with rotation and with reverse circulation.
Unconsolidated sedimentary rocks
They are sand and gravel. They are very permeable. The exploration of groundwater and its study are delicate works so that any erroneous data will influence its results. Therefore, we always advise a specialist company for its realization.
