Groundwater is water that is located at a depth of up to 25 meters from the surface of the earth. It is formed due to various water bodies and precipitation in the form of rain and snow. They seep into the ground and accumulate there. Groundwater differs from groundwater in that it has no pressure. In addition, their difference is that soils are sensitive to changes in the atmosphere. The depth at which groundwater can be located does not exceed 25 meters.
Ground water level
Groundwater is in close proximity to the surface of the earth, however, its level may vary depending on the terrain and season. It will rise in high humidity, especially when it rains heavily and snow melts. And also the level is affected by nearby rivers, lakes, and other bodies of water. During the drought period, the groundwater level drops. At this time, he is considered the lowest.
The groundwater level is divided into two types:
If you make incorrect calculations of the depth of groundwater, then this threatens: flooding the building, destruction of the foundation and other problems.
Groundwater occurrence
To find out where exactly the groundwater lies, you can first conduct simple observations. When the depth of the occurrence is small, the following signs will be visible:
And you can also apply another folk way. Into a clay pot, pour any moisture-absorbing material (for example, salt or sugar). Then weigh it carefully. Pour into a piece of fabric and bury in the ground to a depth of 50 centimeters. After a day to open and weigh again. Depending on the difference in weight, it will be possible to find out how close water is to the surface of the earth.
You can also learn about the presence of groundwater from the hydrogeological map of the area. But the most effective way is exploration drilling. The column method is most often used.
Characteristics
When soil water appears naturally natural, then it is suitable for drinking. The contamination of the liquid is affected by the proximity of villages and cities, as well as the proximity of water to the surface of the earth.
Groundwater is divided into types that differ in their mineralization, so they are as follows:
The hardness of ground water is also distinguished:
In addition, there is groundwater, which contains a lot of harmful substances. Such water is usually located near landfills, with burials of chemical or radioactive waste.
Disadvantages of groundwater
Groundwater also has its drawbacks, for example:
In order for the water to become much better, it is necessary to carefully process it. This will help rid it of various contaminants.
