where is the world's supply of fresh water
Fresh water occurs naturally on the earthâs surface â in lakes, ponds, ice caps and ice shields, glaciers, and rivers and underground as groundwater in underground streams and aquifers. Fresh water has low concentrations of dissolved solids and salts. Canadaâs fresh water resources represent 7 percent of the worldâs renewable fresh water. About 20 percent of the worldâ fresh water is found in Canada, but less than half of it is considered renewable. Most of the fresh water is in the form of fossil water in glaciers, underground aquifers, and lakes.
