  • Distribution of Freshwater - Groundwater

    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...

  • Groundwater observation wells

    The map shows the location of the six hydrogeological regions in Canada and the location of observation wells. The terrain composition is also shown on the map, which includes crystalline rocks, mixed crystalline rocks, folded sedimentary rocks and flat lying sedimentary rocks. The southern limit...

  • Wetland Regions

    Wetlands mainly occur low in the landscape and form areas of groundwater discharge. This aids in the accumulation and composition of peat, as water moves slowly in wetlands. Local topography and sediment characteristics, such as an underlying low-permeability clay layer, can lead to wetlands...

  • Groundwater Usage, Groundwater Geoscience Program

    The amount of groundwater exploited is estimated in m³/year. Groundwater usages are classified in four categories: agricultural, industrial, domestic and energy. Typically, groundwater usage should be represented as a series of sub-polygons or points fitting inside the boundary of the...

  • Groundwater Flow, Groundwater Geoscience Program

    Groundwater flow is the movement of water in an aquifer or hydrogeological unit. The dataset shows groundwater flow rate and direction in the hydrogeological unit. Groundwater flow is establish from piezometric surface map. The method used to create the dataset is described in the metadata...

  • Hydrogeological Regions

    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...

  • Groundwater Samples, Groundwater Geoscience Program

    Groundwater samples have been collected in the hydrogeological unit, for various types of analysis. The dataset is not used to represent a particular phenomenon or observation but rather as a utility dataset to add context and reference to groundwater analysis. It represents a general description...

  • Piezometric Surface, Groundwater Geoscience Program

    Level below which soil or rock is saturated with water, in the well and at the time the level has been measured, expressed in m above the sea level. Groundwater levels measured are interpolated / extrapolated to obtain groundwater level on every cell of the hydrogeological unit raster. Surfer and...

  • Surficial Hydrogeological Materials

    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...
