Spring Water and the Science of Water Circulation
Mechanism of Water Circulation
Spring water is part of the global water cycle. The water cycle consists of the following processes.
- Evaporation: Water from oceans, lakes, rivers, and soil evaporates and becomes water vapor in the atmosphere.
- Condensation: Water vapor is cooled to form clouds.
- Precipitation: Rain or snow falls from clouds to the earth’s surface.
- Infiltration: Part of the precipitation seeps into the ground and becomes groundwater.
- Runoff: Groundwater appears as spring water on the surface or flows into rivers.
- Evaporation again: Water on the surface evaporates again, and the cycle continues.
Groundwater Retention Time
The water that gushing forth as spring water has traveled underground for several years to several decades, or in some cases several centuries, from the time it fell as rain. This retention time varies depending on geological structure and groundwater flow velocity.
The longer the retention time, the longer the water is in contact with rocks and soil, and it will contain more mineral components. Also, natural filtration may remove impurities.
Climate Change and Spring Water
In recent years, it has been pointed out that changes in precipitation patterns due to climate change may also affect the spring water environment.
- Fluctuations in precipitation: The increase in concentrated rainfall and prolonged dry periods may change the pattern of groundwater recharge.
- Rising temperatures: An increase in evapotranspiration may reduce the amount of infiltration into groundwater.
- Decrease in snowfall: A reduction in snowfall in mountainous areas may affect groundwater recharge from spring snowmelt.
