Ground-water use in Canada, 1981 / Paul J. Hess. : En36-503/140E-PDF

"Estimates of the volume of ground-water use in Canada were prepared for 1981. Six maps show the spatial distribution and annual volumes of ground water used by municipal and industrial users. The major findings of this report are the following: (1) over 6.2 million, or 26% of Canadians, rely on ground water for their domestic supply; (2) approximately 38% of the municipalities in Canada rely entirely or partially on ground water; (3) approximately 1.46 billion cubic metres, or about 4% of total water use in Canada, is obtained from ground water (this percentage is increased to 8% if water use by the thermal component within the industrial sector is not included in the calculations); (4) approximately 87% of total water use for livestock is obtained from ground water; and (5) ground water is important for fish enhancement programs"--Abstract, p. vii.
