Groundwater supplies are replenished by rain and snowmelt that occur each year. Water from melting snow and rainfall seeps into the soil and percolates down into the saturated zone. Places where this happens are called recharge areas. In the summer and fall months, recharge areas may appear as dry land. In the late winter and spring, the same areas are full of water that will eventually percolate down into the saturated zone of the aquifer below.

Contact Us Privacy Accessibility. For example, in some parts of Australia surface water is injected into the ground through man-made boreholes, so that water is stored and used more efficiently than it is at the surface known as Managed Aquifer Recharge.
Groundwater pumping and use for town water supplies or agricultural purposes are examples of artificial discharge. Recharge occurs when surface water, either from direct precipitation or from rivers and lakes, percolates downwards through the microscopic spaces in the soil and rock profile.

Aquifers An aquifer is an underground layer of permeable rock, sediment, or soil that yields water. Bedrock aquifers There are numerous bedrock formations deep below the ground. For more information, read the article Digging deep for water in the Fall edition of The Grand. Overburden aquifers Some aquifers are located within the sediment that sits on top of the bedrock.
Other, smaller aquifers are found in sand and gravel seams and supply water to domestic wells. For more information, read the article, Moraines are the backbone of Grand , in the Fall edition of The Grand. Recharge areas Water from the surface - rain or melting snow - moves slowly down through the ground to the aquifers.
