Groundwater Exploration Techniques

Introduction: Groundwater is a precious gift given by nature for free present in aquifers and it is human psychology that we do not care about things that are available for free. Even the groundwater was not able to keep itself out of human exploitation. Groundwater was discovered many years ago. We can assume the level of groundwater as we know that at that time there were only dug wells or shallow wells. Later came into play deep tubewells after handpumps and other pumps. It clearly shows that the groundwater level is going down very fastly due to the over-exploitation. More than 60% of the global population thrives by using groundwater resources. Exploring the groundwater at deep levels is a major challenge to the geological scientists. Renewable resource: YES!!! Groundwater is a renewable resource as we can refill water into the ground using various methods. We can restore water and increase the water table by performing some jobs like installing a rainwater har...
