The water table is defined as the level below which the ground is saturated with water.

The water table is defined as the level below which the ground is saturated with water.

• A. The surface of the water
• B. The level below which the ground is saturated with water
• C. The boundary between freshwater and saltwater
• D. The depth to bedrock

Answer: (B)

Groundwater structure: the water table marks the upper boundary of the saturated zone in the soil. Above this level, the pores in the ground may hold air and water; below it, the pores are filled with water. This boundary shifts with rainfall, recharge, pumping, and the geology of the area. The surface of a body of water is not the water table, which refers to groundwater, not surface water. The boundary between freshwater and saltwater describes salinity gradients at coastlines, not a saturation level in the soil. The depth to bedrock is a geological measurement of rock depth, not the saturation state of the pores. So the level below which the ground is saturated with water is exactly what defines the water table.
