The groundwater moved through the aquifer which was close to the Carrigower River, a designated Special Area of Conservation.
Likewise, most of the water supply for the town of Sonoyta, as well as the nearby border town of Lukeville, comes from the groundwater aquifer .
Therefore, the results of a wet base or a dry base are the same if the upper part of the aquifer is frozen: it is not possible to transmit water from the glacier into the rock mass.
Groundwater comes from an aquifer , an underground zone of saturated sand, gravel, or rock that yields significant quantities of water.
If dry-based ice covered the area, the aquifer would have become inactive.
A less pleasant possibility was that we had intercepted an aquifer .
Chalk rivers are fed from groundwater aquifers , which produce clear waters and a generally stable flow and temperature regime.
The artificial recharge of aquifers could help to counter overexploitation of groundwater resources.
The movement of saline water into freshwater aquifers , or saltwater intrusion, is usually caused by ground water pumping from coastal wells.
Groundwater is found at varying depths underneath the earth's surface, in permeable rocks known as aquifers which are saturated by the infiltration of rainfall.
