Groundwater Section

Groundwater is located below the earth's surface in interconnected pores between soil particles and in bedrock fractures.

Approximately 2/3 of the world's freshwater is found underground. The underground areas of soil or rock where substantial quantities of groundwater are found are called aquifers.

Water found in aquifers can be tapped by man through dug and drilled wells, and often appears at the surface as springs.

Approximately 29% of Newfoundland's population rely on groundwater as a source of potable water.

The Groundwater Section has responsibility for the conservation, development, control, improvement, and proper utilization of the groundwater resources of the province.
