An aquifer is a body of rock and/or sediment that holds groundwater. Groundwater is the word used to describe precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground. There are two general types of aquifers: confined and unconfined..

Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface. Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone.
Does Botany Bay aquifer have groundwater contamination?
As a number of contaminated sites in the Botany Bay area have resulted in the contamination of groundwater in the aquifer, the NSW Office of Water has developed a management approach for the Botany Bay Sands Aquifer.
Is the Botany Sands aquifer safe to drink?
Whilst the Botany Sands aquifer is still a key source of groundwater in Sydney’s south eastern suburbs, the increasing use of land above the aquifer for industry, golf courses and garden watering, among other things, have caused the groundwater to become contaminated due to the industrial pollutants and is therefore unsafe for drinking.
What is the Botany aquifer?
The Botany Aquifer is a large volume of underground water present in the sandy ground surrounding Botany Bay which runs from Centennial Park to the Botany Wetlands and into Botany Bay.
What is the Botany Bay Sands aquifer zone?
Based on the NSW Government’s concerns about contamination in the Botany Bay Sands Aquifer Area, the area has been divided into four groundwater management zones. In Zone 1, all use of groundwater is prohibited.

Underground layer of water-bearing permeable rock
An aquifer is an underground layer of water-bearing, permeable rock, rock fractures, or unconsolidated materials. Groundwater from aquifers can be extracted using a water well. Water from aquifers can be sustainably harvested through the use of qanats. Aquifers vary greatly in their characteristics. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology. Related terms include aquitard, which is a bed of low permeability along an aquifer, and aquiclude, which is a solid, impermeable area underlying or overlying an aquifer, the pressure of which could lead to the formation of a confined aquifer. The classification of aquifers is as follows: Saturated versus unsaturated; aquifers versus aquitards; confined versus unconfined; isotropic versus anisotropic; porous, karst, or fractured; transboundary aquifer.
The Biscayne Aquifer
The Biscayne Aquifer, named after Biscayne Bay, is a surficial aquifer. It is a shallow layer of highly permeable limestone under a portion of South Florida. The area it underlies includes Broward County, Miami-Dade County, Monroe County, and Palm Beach County, a total of about 4,000 square miles (10,000 km2).
The Edwards Aquifer is one of the most prolific artesian
Source of drinking water in Texas
The Edwards Aquifer is one of the most prolific artesian aquifers in the world. Located on the eastern edge of the Edwards Plateau in the U. S. state of Texas, it is the source of drinking water for two million people, and is the primary water supply for agriculture and industry in the aquifer's region. Additionally, the Edwards Aquifer feeds the Comal and San Marcos Springs, provides springflow for recreational and downstream uses in the Nueces, San Antonio, Guadalupe, and San Marcos river basins, and is home to several unique and endangered species.
The following is a partial list of aquifers around the world. A category-based list of aquifers is also available.

The Lotikipi Basin Aquifer is a large aquifer in the northwest region of Kenya containing 200 billion cubic meters of saline water and covers an area of 4,164 km2. The aquifer, discovered in September 2013, is nine times the size of any other aquifer in Kenya and has the potential to supply the population with enough fresh water to last 70 years or indefinitely if properly managed.
The Nubian Sandstone Aquifer System (NSAS) is the world's largest known
Fossil water aquifer system in northeastern Africa
The Nubian Sandstone Aquifer System (NSAS) is the world's largest known fossil water aquifer system. It is located underground in the Eastern end of the Sahara desert and spans the political boundaries of four countries in north-eastern Africa. NSAS covers a land area spanning just over two million km2, including north-western Sudan, north-eastern Chad, south-eastern Libya, and most of Egypt. Containing an estimated 150,000 km3 of groundwater, the significance of the NSAS as a potential water resource for future development programs in these countries is extraordinary. The Great Man-Made River (GMMR) project in Libya makes use of the system, extracting substantial amounts of water from this aquifer, removing an estimated 2.4 km3 of fresh water for consumption and agriculture per year.
The Ogallala Aquifer is a shallow water table aquifer surrounded by sand
Water table aquifer beneath the Great Plains in the United States
The Ogallala Aquifer is a shallow water table aquifer surrounded by sand, silt, clay, and gravel located beneath the Great Plains in the United States. As one of the world's largest aquifers, it underlies an area of approximately 174,000 sq mi (450,000 km2) in portions of eight states. It was named in 1898 by geologist N. H. Darton from its type locality near the town of Ogallala, Nebraska. The aquifer is part of the High Plains Aquifer System, and resides in the Ogallala Formation, which is the principal geologic unit underlying 80% of the High Plains.
The Waiwhetu artesian aquifer
Aquifer in Wellington, New Zealand
The Waiwhetu artesian aquifer, sometimes referred to as the Hutt aquifer, is a pressurized zone of water-retaining sand, gravel and boulders beneath the Hutt Valley and Wellington Harbour in New Zealand. The aquifer provides about 40% of the public fresh water supply for Lower Hutt and Wellington city. Water from the Hutt River begins to flow underground south from Taita Gorge, then becomes pressurized under a seal of clay. Water is extracted from the pressurized area for public use, but concerns about overuse and damage by earthquakes have led to investigations of alternative sources of fresh water.
The Yarkon-Taninim Aquifer, also known as the Western Mountain Aquifer of Israel/Palestine, is the western and larger part of the Mountain Aquifer, which also contains the Eastern and the smaller North-Eastern (Mountain) Aquifers. The Mountain Aquifer and the Coastal Aquifer are the main aquifers shared by Israel in its pre-1967 borders, and Palestine . It has been the main longterm reservoir of the Israeli water system.
