SOURCES OF WATER POLLUTION (Cont)
While surface water is found in the form of rivers and lakes, groundwater is stored in aquifers. Aquifers are formations of cracked rock, sand, or gravel that hold water and yield enough water to supply wells or springs. More than 95 percent of the world’s usable water resources are stored in its groundwater.
Approximately third-quarter of all Nigerians depends on groundwater for their drinking water. In most times, 80 percent of all Nigerians depend on groundwater for their drinking water, and more than 97 percent of all rural Nigerians, depend on groundwater for their drinking water supplies.
