Abstract(unpublished)
The map shows the quantity and quality of groundwater. The quality is the total dissolved solids in parts per million. The quantity is expressed in litres per second. During the Pleistocene epoch Canada was almost entirely covered by glaciers. Hence, although there are extensive and hydrologically important alluvial (river) deposits, as well as lesser areas of eolian (wind-deposited) materials, the country's unconsolidated surficial materials are predominantly of glacial derivation. These highly variable and irregular glacial materials contain many of the best local near-surface aquifers. The groundwater resource potential of the materials depends on their intergranular porosity and permeability, which result from the mode of deposition. Some glacial materials were deposited directly by ice; others, by running water and standing meltwater. In size they range from a very fine rock flour and clays through sands and gravels to large blocks. Tills and clays, however, are the predominant glacial deposits
