[หษกraสndหwษหtษr ]
Definition
water source
Groundwater is water that is held underground in the soil or in pores and fractures of rock. It is a key component of the hydrological cycle and provides a significant source of freshwater for drinking, agriculture, and industry. Often found in aquifers, groundwater can be accessed through wells and springs.
Synonyms
aquifer water, subsurface water, well water.
Examples of usage
- Farmers rely on groundwater for irrigation in dry seasons.
- Contamination of groundwater can lead to serious health issues.
- Testing groundwater levels helps in understanding drought conditions.

Interesting Facts
Hydrology
- Over 97% of the Earth's fresh water is found underground, making it crucial for drinking water and agriculture.
- Groundwater comes from rain and melting snow that seeps into the ground, a process called infiltration.
Environmental Impact
- Over-extraction of groundwater can lead to subsidence, where the ground sinks due to the loss of support from underground water.
- Pollution from pesticides, fertilizers, and waste can contaminate groundwater, making it unsafe for drinking.
Cultural Significance
- Many ancient civilizations relied on groundwater for their survival, digging wells which became community gathering spots.
- In places like the Middle East, traditional water management practices for wells and qanats reflect a deep respect for this hidden resource.
Geological Aspects
- Groundwater exists in aquifers, which are layers of rock that can store and transmit water effectively.
- The depth of groundwater can vary greatly depending on the geographical location and environmental factors.
Climate Change
- Changes in climate can affect recharge rates of groundwater, leading to significant impacts on water availability.
- As surface water sources dry up, reliance on groundwater can increase, stressing these resources further.
Origin of 'groundwater'
The term 'groundwater' combines the words 'ground' and 'water.' 'Ground' comes from the Old English 'grund,' meaning the solid surface of the earth or the bottom of a body of water. 'Water' is derived from the Old English 'wรฆter,' which can be traced back to Proto-Germanic and Proto-Indo-European roots. Groundwater has been an important resource for humans throughout history, as underground aquifers have provided drinking water and irrigation for thousands of years. Understanding groundwater's role in the environment has become increasingly important with the rise of industrialization and urbanization, making the study of hydrology critical for sustainable resource management.
