How to know where to dig a borehole

Before drilling a well, the final drilling location is usually determined based on multiple factors. The most effective method is usually based on the direction of the  river or the location of the existing water source. In fact, some groundwater detection equipment can also effectively detect the location of groundwater.

Follow these 4 steps can help you to locate where to drill a borehole:

1. Hydrogeological Assessment: A hydrogeological assessment is conducted to understand the local geology, aquifer characteristics, and groundwater availability. This assessment involves studying geological maps, analyzing existing borehole data and water well records, and evaluating hydrological parameters such as rainfall patterns, surface water features, and groundwater levels.

2. Geophysical Surveys: Geophysical methods, such as resistivity surveys, seismic surveys, or ground-penetrating radar, are often employed to provide subsurface information. These surveys help identify potential water-bearing formations, delineate aquifer boundaries, and detect geological structures that may influence groundwater flow.

3. Site Selection Criteria: Based on the hydrogeological assessment and geophysical surveys, specific criteria are established to guide the selection of potential borehole sites. These criteria may include proximity to known water-bearing formations, depth to groundwater, water quality, accessibility, and considerations for future development or expansion.

4. Field Investigations: Field investigations are conducted to verify the findings from the desk studies and geophysical surveys. This may involve drilling exploratory boreholes or installing test wells to collect groundwater samples, measure water levels, and assess aquifer properties.
