underground water-bearing layer
A layer of rock, sand, or gravel under the ground that holds water and can supply wells or springs.
用法パターン：
an aquifer; [water] from an aquifer; [an aquifer] beneath [place]
よくある間違い：
Do not confuse an aquifer with an underground lake or with the water table; an aquifer is usually a porous layer of rock or sediment that holds and carries groundwater.
類義語
water-bearing layer (A clear descriptive term, but less established and less technical than aquifer.)
|
groundwater reservoir (Emphasizes stored water; less precise because an aquifer is the geological layer that stores and transmits it.)

pollution of an aquifer
Pollution that makes water in an aquifer unsafe or lower in quality.
例文
- Officials found evidence of aquifer contamination near the old industrial site.

aquifer depletion
1/ˈækwəfɚ dɪplˈiʃən/
fixed phrase
technical
loss of groundwater storage
The loss of water from an aquifer, often because people pump out too much water.
例文
- Aquifer depletion is a major concern in regions that depend on irrigation.
- Decades of pumping have led to serious aquifer depletion under the plains.
- New water rules aim to slow aquifer depletion and protect local wells.
aquifer recharge
1/ˈækwəfɚ ɹit͡ʃˈɑɹd͡ʒ/
fixed phrase
technical
refilling an aquifer
The process of adding water back into an aquifer.
例文
- The city is testing aquifer recharge by directing stormwater into spreading basins.
- Wet winters can increase aquifer recharge after years of drought.
- Managed aquifer recharge is used to store excess water underground.
aquifer storage and recovery
1/ˈækwəfɚ stˈɔɹɪd͡ʒ ˈænd ɹɪkˈʌvɚi/
fixed phrase
technical
storing and retrieving groundwater
A system that puts water into an aquifer and takes it out later when needed.
例文
- The utility is considering aquifer storage and recovery to prepare for dry years.
- In an aquifer storage and recovery system, treated water is injected underground and recovered later.
- The success of aquifer storage and recovery depends on local geology and water quality.
artesian aquifer
1/ˌɑɹtˈiʒən ˈækwəfɚ/
fixed phrase
technical
pressurized aquifer feeding wells

例文
- The farm's flowing well is supplied by an artesian aquifer.

confined aquifer
1/kənfˈaɪnd ˈækwəfɚ/
fixed phrase
technical
pressurized enclosed aquifer
An aquifer sealed between layers of rock or clay, with water under pressure.
例文
- The well taps a confined aquifer more than 200 meters below the surface.
- Water in a confined aquifer may rise in a well because it is under pressure.
- Engineers mapped the clay layer above the confined aquifer.

fixed phrase
technical
ancient slowly renewed aquifer
An aquifer with very old water that is not replaced quickly.
例文

unconfined aquifer
1/ˌʌŋkənfˈaɪnd ˈækwəfɚ/
fixed phrase
technical
aquifer open to surface recharge
An aquifer that can be refilled directly by water moving down from the surface.
例文
