Groundwater 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...

Surficial hydrogeological materials show the distribution of sediment deposited in glacially influenced environments. Most drinkable groundwater resources in Canada occur in shallow surficial-sediment aquifers. Surface sediments, such as gravel, sand, silt and clay, or mixed sediments, are an...

Hydrogeological regions are areas in which the properties of sub-surface water, or groundwater, are broadly similar in geology, climate and topography. Hydrogeology is the branch of geology that deals with the distribution and movement of water beneath the earth’s surface. This map shows Canada’s...
