This refers to water that is potable and usable for all terrestrial organisms.
It has a low concentration of dissolved salts.
About 3% of Earth's water is freshwater.
The following are two sources of freshwater:
Rainfall: Various forms of precipitation like rain, hail, sleet, and snow are sources of freshwater that replenish the groundwater and maintain the water table and underground water level.
Surface water: This involves reservoirs of freshwater that include lakes, rivers, and ponds. These are the major agricultural sites and have rich, fertile alluvial soil.
