What is hydrogeological documentation?
Hydrogeological documentation is a compilation that contains the results of geological studies. It is obtained through well drilling, determination of groundwater resources, or analysis of building drainage systems.
The purpose of creating such documentation is to archive hydrogeological studies and determine groundwater resources, including exploitable and disposable resources. Therefore, each hydrogeological documentation helps to better understand the geology and groundwater resources in Poland.
What should hydrogeological documentation contain?
As mentioned earlier, hydrogeological documentation should include the results of conducted geological studies. To be accurate and comprehensive, it should encompass:
- Description of the geological structure of the area
- Characteristics of groundwater
- Hydrogeological parameters
- Determination of disposable and exploitable resources
- Assessment of the groundwater quality
- Conclusions
What are the stages of creating hydrogeological documentation?
The creation of hydrogeological documentation begins with the analysis of available archival data in the State Geological Institute’s database. The next step involves fieldwork, including drilling, measurements, and sampling of water, soil, etc.
The collected samples are analyzed in the laboratory, and the obtained data must be properly interpreted. Based on this, relevant calculations are performed, along with drawings depicting hydrogeological cross-sections, maps, and schematics. All these steps contribute to the development of comprehensive hydrogeological documentation.
When is hydrogeological documentation needed, and who prepares it?
Hydrogeological documentation is required for various activities related to the exploitation of groundwater. It is necessary, among other things, when:
- Establishing a water facility (groundwater intakes) or legalizing it
- Withdrawing groundwater
- Determining the water resources of major groundwater reservoirs
- Permanently lowering groundwater levels, e.g., in mining operations
- Executing building drainage systems
- Utilizing medicinal waters
Geological and mining law mandates that in the mentioned cases, hydrogeological documentation must be prepared by a qualified hydrogeologist. With professional knowledge, they can conduct thorough investigations and appropriately analyze the results.
Every investment is different
Due to varied hydrogeological conditions, each investment is unique. For instance, if a well is planned to be deeper than 100 meters, an additional environmental decision and a mining movement plan should be obtained.
Moreover, if there are other groundwater intakes within a distance of less than 500 meters or the planned intake has a withdrawal rate exceeding 10 m3/h, it is considered an undertaking that could significantly impact the environment, and an environmental decision must also be obtained.
It is essential to remember that every hydrogeological documentation should be preceded by the preparation of a geological work project and its approval by the relevant public administration authority. The geological work project provides a detailed instruction for the geological activities needed to establish a water facility, such as a well.
