The top surface of groundwater is called the water table. It represents the boundary between the unsaturated zone above, where soil pores contain both air and water, and the saturated zone below, where all pores are filled with water. The water table fluctuates with factors such as precipitation and human activities.
The two types of groundwater are shallow groundwater and deep groundwater. Shallow groundwater is found closer to the surface, typically within the first few hundred feet of the Earth's surface. Deep groundwater is located deeper underground, often thousands of feet below the surface.
Groundwater is generally more plentiful than surface water. It is estimated that about 30 times more freshwater is stored as groundwater compared to surface water. Groundwater is stored in underground aquifers and is replenished by precipitation and surface water sources.
Groundwater is typically closest to the Earth's surface in stream valleys due to the topography and geology of these areas. Water from streams can infiltrate into the ground, recharging the groundwater system and bringing it closer to the surface in these valley locations. This proximity to the surface in stream valleys makes them important areas for groundwater recharge and interactions between surface water and groundwater.
Groundwater is connected to surface water through a process called groundwater-surface water interaction. This occurs when groundwater discharges into surface water bodies such as rivers, lakes, and oceans, providing a source of water and nutrients. Conversely, surface water can also recharge groundwater systems through infiltration and percolation. This interaction is important for maintaining water quality and ecosystem health.
A spring is considered part of the groundwater system because it is where groundwater flows naturally to the Earth's surface. When the water table intersects the ground surface, or when pressure forces water up to the surface, it emerges as a spring, providing a visible outlet for groundwater.

Groundwater can become surface water through processes like seepage, springs, or wells. When groundwater levels rise high enough to intersect the ground surface, it emerges as surface water.
Surface water and groundwater are connected through a process called recharge and discharge. When surface water infiltrates into the ground, it recharges the groundwater system. Groundwater can also discharge into surface water bodies such as rivers, lakes, or oceans, maintaining vital connections between the two systems.
Groundwater is found underground in porous rocks and sediments, while surface water is found in rivers, lakes, and streams. Groundwater moves very slowly compared to surface water. Groundwater is less susceptible to evaporation, pollution, and temperature fluctuations compared to surface water.
