👉 Groundwater is a subsurface water resource that flows through porous and permeable materials like soil and rock, typically found beneath the Earth's surface. It is formed when precipitation seeps into these materials and accumulates in aquifers, which are geological formations capable of storing and transmitting significant volumes of water. Groundwater fluid consists of water molecules that are suspended within these porous media, and it can move due to gravity, pressure gradients, or capillary forces. This fluid is crucial for various ecological and human needs, including drinking water supply, irrigation, and maintaining base flow in rivers and streams. The movement and quality of groundwater fluid are influenced by factors such as soil composition, geological structure, and human activities like pumping and contamination.
