What is the description of spring water?

Spring water is best described as water that emerges from water-bearing formations reaching the surface. This process occurs when groundwater naturally flows to the surface due to pressure or geological formations, creating springs. The water typically originates from aquifers, which are layers of permeable rock or sediment that can hold and transmit water. When the pressure in these formations forces the water out, it creates a spring, which can flow continuously or intermittently depending on various hydrological conditions.

In contrast, water under pressure refers to water that may be confined in certain geological settings but does not necessarily reach the surface as spring water. Water collected in reservoirs involves water being stored in artificial structures or natural depressions, rather than flowing naturally from an aquifer. Finally, water evaporating from the soil pertains to a completely different process related to the hydrological cycle and does not represent how spring water is defined.
