Groundwater is water located beneath the Earth's surface in soil and rock pores and fractures. It is contained in geologic formations called aquifers. There are two types of aquifers - confined aquifers that are sandwiched between layers of impermeable rock or sediment, and unconfined aquifers where the water table lies below layers of permeable rock or sediment. Groundwater is an important resource that is used for drinking water, agricultural irrigation, and industrial uses by many communities.

Groundwater is the water present beneath
Earth's surface in rock and soil pore spaces
and in the fractures of rock formations.

called aquifers.

How groundwater is
formed?
Most groundwater comes from
precipitation.
Precipitation is any product of the
condensation of atmospheric water vapor
that falls under gravitational pull from
clouds.

CAPILLARY
FRINGE
The capillary fringe is the subsurface layer
in which groundwater seeps up from a
water table by capillary action to fill pores.
WATER TABLE
The water table is an underground
boundary between the soil surface and
the area where groundwater saturates
spaces between sediments and cracks in

Where is Groundwater Stored?
> Groundwater is stored in rock
bodies called aquifers. A good
aquifer provides both storage and
transmittal of groundwater.

Aquifer is a body of rock and/or sediment
that holds groundwater.
There are two general types of
aquifers:
Confined
Unconfined
have a layer of
impenetrable rock
or clay above them
lie below a
permeable layer of
➡️
➡️

12. Characteristics of aquifers:
➡️ Porosity
The number and size of pore spaces, fractures,
joints, in bedrock
Provides Storage for groundwater •
➡️ Permeability
The connectedness of pore spaces, fractures,
joints in bedrock.
Provides Transmittal for groundwater.

13. An aquitard is also a saturated formation. It permits
the water through it but does not yield water in
sufficient quantity as much as aquifer does. It is
because of their partly permeable nature. But
however, if there is an aquifer under the aquitard then
the water from aquitard may seep into the aquifer.
Here, the clay particles block the voids present in the
sand and make it partly permeable.
AQUITARD

14. Sandy clay is a perfect example of an
aquitard.

15. An aquiclude is a geological
formation which is impermeable to
the flow of water. It contains a large
amount of water in it but it does not
permit water through it and also
does not yield water. It is because of
its high porosity.
AQUICLUD
E

16. Clay is an example of
aquiclude.

17. An aquifuge is an impermeable
geological formation which is
neither porous nor permeable –
which means it cannot store water
in it and at the same time it cannot
permit water through it.
AQUIFUG
E

18. Compact rock is an example of
aquifuge.

19. WHO USES
GROUNDWATER ?
Almost all human will use
groundwater either directly
pumping it into their own cistern
or though major metropolitan
water transportation system.

Groundwater is a very important natural
resource and has a significant role in the
economy. It is the main source of water for
irrigation and the food industry. In general
groundwater is a reliable source of water
for the agriculture and can be used in a
flexible manner.
