The term commonly used to refer to groundwater found in aquifers is "subterranean water." This terminology emphasizes that the water is located beneath the earth's surface, stored in geological formations that have the capacity to hold water, known as aquifers. These aquifers can contain significant amounts of water, which can be drawn for various uses, such as irrigation, drinking, and industrial processes.

While potable water is indeed water that is safe for human consumption, not all groundwater is potable. The quality of groundwater can vary widely depending on various factors, including the geology of the aquifer, the presence of contaminants, and treatment methods. Therefore, while some subterranean water is potable, it is not universally the case.

Surface water refers to water found on the Earth's surface, such as rivers, lakes, and reservoirs, and does not pertain specifically to groundwater. Pressurized water usually describes water in a specific context of being under pressure, often in wells or piped systems, but does not accurately capture the essence of groundwater in aquifers.
