Seeking hydrogeological expertise
Harnessing the knowledge and expertise of hydrogeologists is essential for achieving sustainable water management. By consulting these experts and employing advanced techniques such as Vertical Electrical Sounding (VES) studies, communities and individuals can gain a comprehensive understanding of groundwater dynamics in their areas. These studies accurately identify aquifer locations and storage capacities, providing crucial insights into properties, depth, yield, and spatial distribution. Armed with this information, informed decisions can be made regarding borewell placement and effective recharge strategies.
At GoodEarth Malhar, the team recognised the importance of scientific intervention when faced with challenges in replenishing groundwater. Mr Ashok Kumar, a geologist, played a pivotal role in providing a more holistic view of the efforts already expended at Malhar. Through the conduct of VES studies, Ashok’s expertise provided a comprehensive water map of the area, which revealed a significant decline in groundwater levels over the years. Pointing at an important finding of the study, Prashanth Palanisamy, Director – Design at GoodEarth, highlighted how Malhar received 150 million litres of water through rain every year, while the community as a whole needed only 90 to 100 million litres, leaving a surplus of 40 to 50 million litres of rainwater. This surplus indicated the potential for saving a significant amount of water and replenishing the groundwater aquifer through scientific and concerted efforts.
Recognising the need to replenish the groundwater aquifer, the team understood that thoughtful intervention was required. These findings not only shed light on the current situation but also revealed a silver lining—a possibility to conserve and restore the balance of water resources. Through scientific and concerted efforts, the surplus rainwater can be effectively managed, saving valuable water and replenishing the groundwater aquifer. This knowledge serves as a driving force to implement sustainable practices and ensure the long-term availability of this precious resource.
