Web22 jul. 2024 · Groundwater is transported through aquifers because of two main reasons: gravity and pressure. In unconfined aquifers which we concentrate on because they are more likely to be contaminated water always flows from high points to low points because of gravity. Why do liquids flow Short answer? WebGroundwater comes from rainfall and surface flow, where it seeps into the ground and slowly makes its way downhill toward the sea. Water exists everywhere beneath the ground surface, and most of this occurs within 2,500 feet (750 m) of the sur- face.
