groundwater
Water that is located beneath the earth's surface in the cavities of rocks and sediments and represents an important source of drinking water.
Durch die anhaltende Trockenheit ist der Grundwasserspiegel stark gesunken.
Due to the ongoing drought, the groundwater level has fallen sharply.
The word is clearly composed of 'Grund' (ground) and 'Wasser' (water). So it literally refers to the water that is located in the soil or ground.
In vielen Regionen wird Trinkwasser aus dem Grundwasser gewonnen.
In many regions, drinking water is obtained from groundwater.
Common phrases are 'der Grundwasserspiegel steigt/sinkt' (the groundwater level rises/falls), 'das Grundwasser ist verschmutzt/verunreinigt' (the groundwater is polluted/contaminated), and 'Grundwasser abpumpen' (to pump out groundwater).
Wegen des wenigen Regens sinkt der Grundwasserspiegel immer weiter.
Because of the lack of rain, the groundwater level keeps falling further.
'Grundwasser' (groundwater) is a key term in discussions about the environment, climate change, agriculture, and water supply. You often find it in the news and specialist texts.
Ein neuer Bericht warnt vor der zunehmenden Verschmutzung des Grundwassers.
A new report warns of the increasing pollution of groundwater.
rainwater
'das Grundwasser' and 'das Regenwasser' are both water from nature. They can be confused because rainwater can later seep into the ground and become part of the groundwater. But 'Regenwasser' first means the water that comes from the sky as rain, for example onto a roof or into a barrel. 'Grundwasser' is located underground, in soil, rock, or sand, and is often important for drinking water. If you are talking about collecting water after a rain shower, 'Regenwasser' fits. If it is about water underground or wells, 'Grundwasser' fits.
