AbstractGroundwater is water found beneath the earth’s surface
and located at the water table below. In Canada, there is more water underground
than on the surface. Groundwater occurs in the tiny spaces between loose materials
on top of bedrock, or in cracks of bedrock. The most important concentrations
are in aquifers, near the top level of the water table. About eight million
people, or 26% of the population, depend on groundwater. Approximately two-thirds,
or five million, of these users live in rural areas. Groundwater is also used
for livestock watering, irrigation, aquaculture (fish farms), and mineral and
hydrocarbon extraction.
