Water is an essence food and basic component of life. The need for water is strongly ascending and has a diversified function, which is not only important for drinking purposes but is also vital for any developmental activities. Nowadays, the use and sustainability of water is getting more complex due to population growth, urbanization and industrialization. Any development is related either directly or indirectly with water utilization.
For any developmental activity, both surface and groundwater sources are the main components depending on their quality and availability. In an area where surface water is not feasible for the desired activity, groundwater is the second alternative, if it has the anticipated amount and quality. Therefore, site investigation/ exploration, sometimes called a pre-construction evaluation, has to be performed primarily for an effective and sustainable utilization of groundwater resources.
Groundwater has become immensely important for the different water supply purposes in urban and rural areas of both the developed and developing countries. However, groundwater exploration in hard rock terrain is a very challenging and difficult task, if the promising groundwater zones are associated with fractured and fissured media . In such an environment, the groundwater potentiality depends mainly on the thickness of the weathered/ fractured layer overlying the basement.
Groundwater can be explored using different methods. The four major groundwater exploration methods are the areal method, surface method, subsurface method and esoteric methods. Among these methods, esoteric method is not based on science, mostly based on traditional indicators.
New method --- Natural electric field frequency selection
PQWT automatic mapping water detector is based on the Earth's electromagnetic field as the field source, based on the difference in the conductivity of different underground geological structures, and by studying the variation law of the electric field components at different frequencies to study the geological structure and changes, to find groundwater resources by scientific method. Changes in geological structure are displayed in real-time through multiple curves. Automatic form mapping geological profile by one key operate easily, get rid of complicated computer graphics. The site can quickly understand the geological structure through the automatic mapping curve and profile, and analyze specific information such as aquifers, fractures, faults, and caves. The instrument is widely used in the rapid analysis of geological structure changes in different terrains such as plains, hills, mountains, plateaus, and basins to determine well locations, aquifers, and aquifer depth.
