groundwater and aquifers.

Detailed explanation-1: -Much of the water we use for domestic, industrial, or agricultural purposes is groundwater. Most groundwater, including a significant amount of our drinking water, comes from aquifers. In order to access this water, a well must be created by drilling a hole that reaches the aquifer.
Detailed explanation-2: -The main source of groundwater is the rain. The rainwater and water from other sources such as rivers, lakes and ponds, seeps through the ground and fills the empty spaces between the soil and the rocks below the earth. Handpumps or tube wells are used to pump out ground water.
Detailed explanation-3: -Groundwater is water that occurs in the subsurface. An aquifer is a geologic material (rocks and sediments) capable of delivering groundwater in usable quantities. Most rocks and sediments contain open spaces between grains known as pores.
