An Overview of Hydrogeological Survey Report
A Hydrogeological survey report ensures the investigation of a specific area's subsurface hydrologic and geologic parameters. The report entails a survey of the water-bearing levels as well as the filtration capacity of rocks. Furthermore, it plays a crucial role in determining the standardization concerning groundwater operational management structural patterns.
Hydrogeological survey reports have been conducted in the study area to understand better the local geology, geomorphology, drains network, aquifer qualities, and well yield. Moreover, the report gathering data during such a study can be used to create hydrogeological maps. It is explicit that the hydrogeological survey report encourages optimistic approach in the direction of upgrading groundwater levels to a larger extent.

What is a Hydrogeological Survey Report?
A hydrogeological survey report is a report that provides for investigating a specific area's subsurface hydrologic and geologic parameters. It is prepared to study the area & better understand the local geology, geomorphology, drains network, and aquifer qualities of the area. Furthermore, it plays a crucial role in determining the standardization concerning groundwater operational management structural patterns.
Projects that Require Hydrogeological Survey Report Application
The hydrogeological survey is conducted for small, medium or large-scale industries depending upon the project and its purpose. However, the project gives an ultimate pit limit as the approved plan for the mining business, with an impact on the groundwater. Some of the major mining projects that require to submit the hydrogeological survey report application are as listed below:
Importance of Hydrogeological Survey Report in India
The importance of developing a detailed hydrogeological survey report is as discussed below:
- Provides Valuable Information: The hydrogeological survey report provides valuable information with respect to the geological and hydrogeological conditions of an area, including the availability, quality, and movement of groundwater.
- Helps in Decision-Making: The hydrogeological survey report assists in making informed decisions with respect to the groundwater management, such as identifying suitable locations for well construction, assessing the potential impacts of land use activities on groundwater resources, and developing effective groundwater protection strategies.
- Identifies Potential Risks: The comprehensive hydrogeological survey report ensures identifying the potential risks or threats over the groundwater resources, such as contamination, over extraction, and depletion.
- Helps in Resource Management: The comprehensive hydrogeological survey report assists businesses with management and improvement of groundwater resources in a particular area, such as aquifer characteristics, recharge rates, and water quality.
- Facilities Compliance: The comprehensive hydrogeological survey report ensures facilitating the compliance with regulatory requirements related to groundwater management as outlined by Central Groundwater Branch.
- Reduced Risk of Contamination: The hydrogeological survey report ensures reducing the risk of contamination of borehole water by identifying potential sources of contamination and by recommending appropriate mitigation measures.
- Increased Chances of Success: The hydrogeological survey reporting is a process for assessment which ensures increasing the chance of success of a borehole by identifying the best location for the borehole and by recommending the appropriate borehole design and construction specification.
Types of Hydrogeological Survey Report
The different types of hydrogeological survey reports conducted based on the purpose of the procedure are as discussed below:
- Small-Scale Hydrogeological Survey: A small-scale hydrogeological survey (1:1,000,000-1:500,000) is conducted in regions that have never been investigated before. The survey is conducted in order to gather the preliminary information concerning the ability of the rocks in the area retaining water and overall quality of the underground water.
- Medium-Scale Hydrogeological Survey: A medium-scale hydrogeological survey (1:200,000-1:100,000) is a more detailed survey conducted to collect data for hydrogeological mapping. The survey ensures the mapping of water-bearing structures and further conducts a detailed study concerning the retentive capacity of the rocks in the region.
- Large-Scale Hydrogeological Survey: A large-scale hydrogeological survey (1:50,000 and larger) is typically initiated to address specific issues during the engineering and operational planning stages. The survey ensures identifying the areas for water collection and examining the underground water reserves. Moreover, drilling processes, assessment of the composition & quantity of underground water, and proper flow measurement are also required for large and medium-scale assessments.
