Groundwater sampling is the process of collecting water from underground aquifers to analyze its quality and composition. This is typically done using specialized equipment, such as sampling wells or pumps, which help extract water from various depths. The samples are then tested for contaminants, minerals, and other substances to assess the health of the groundwater. The results of groundwater sampling are crucial for understanding the safety of drinking water and the impact of human activities on water resources. This information can guide environmental policies and help in the management of aquifers to ensure sustainable use and protection of these vital resources.
