How are groundwater and surface water connected to each other? How are they different?

Surface water bodies can gain water from groundwater, or are a source of recharge to groundwater. As a result, withdrawal of water from streams and rivers can deplete groundwater or conversely, the pumping of groundwater can deplete water in streams, rivers, lakes, wetlands, and springs. So overall Groundwater discharges into a watershed, where it becomes surface water. Surface water collects in a watershed and seeps into the ground. (Thats how they are connected to each other). They are different- Groundwater is located underground in large aquifers and must be pumped out of the ground after drilling a deep well. Surface water is found in lakes, rivers and streams and is drawn into the public water supply by an intake. Groundwater is water contained in or by a subsurface layer of soil or rock.
