The world's second largest aquifer is the Guarani Aquifer, located beneath parts of Brazil, Argentina, Paraguay, and Uruguay. It is a vital source of freshwater for the region.
The point on Earth's surface where water enters an aquifer is called a recharge zone. This is typically an area where water can percolate through the soil and infiltrate the aquifer layer beneath. Recharge zones are important for replenishing groundwater supplies.

The Ogallala Aquifer in the United States is a large underground aquifer spanning eight states and providing water for irrigation and domestic use. It is an important source of water for agriculture in the Midwest.
The Ogallala Aquifer recharges slowly because the overlying soil and vegetation limit the amount of rainfall and snowmelt that can infiltrate into the aquifer. Additionally, the aquifer's large size and depth also contribute to the slow rate of recharge.
An aquifer typically has high porosity and permeability, allowing water to easily flow through it. In contrast, a layer of shale beneath the aquifer usually has low porosity and permeability, meaning it does not allow water to pass through easily. This difference in characteristics affects the movement and storage of water within the subsurface.
According to newarkadvocate.com, "Pataskala gets its drinking water from an aquifer located more than 100 feet beneath the ground. It is recharged [. . .] by rain and water flowing from the South Fork of the Licking River."
The Edwards Aquifer recharge zone is the area where water seeps into the Edwards Aquifer, a large underground limestone formation, replenishing its water levels. This zone is crucial for maintaining the aquifer's water supply and supporting ecosystems dependent on it.

Fivemile Prairie appears to be an island in the Spokane Aquifer Atlas due to the unique geological formation that surrounds it. The aquifer boundaries are determined by the distribution of aquifer materials beneath the surface, which may give the impression of the prairie standing out as an island within the aquifer. This can be influenced by the hydrogeological characteristics of the area, such as the distribution of sedimentary deposits that control groundwater flow.
The Ogallala Aquifer covers approximately 174,000 square miles beneath parts of eight U.S. states, primarily in the Great Plains region. It is one of the largest freshwater aquifers in the world, supplying water for irrigation and drinking water for millions of people.
