What is the most common method for removing groundwater?

• a well bored into the zone of saturation

• accessing the water table by use of low-grade explosives

• building a water tower

• damming up a river

Sand is ___________, meaning that water can pass through easily.

• Permeable

• Impermeable

• Solid

• Soft

Water from precipitation soaks down through permeable rock and soil layers.  These layers contain air as well as water, so they are NOT filled, with water.  This top layer is the
