2. Groundwater:-
• A portion of water which is penetrated into the
earth is called the groundwater. Not all the
underground water is groundwater. The water
collecting into (in a) well is a groundwater.
• Source of groundwater is rain and snow that falls
to the ground a portion of which percolates down
into the ground to become groundwater.

3. Type of Groundwater
• Groundwater classified according to its origin.

4. 1. Juvenile Water
• Magmatic water
• Volcanic water
• Cosmic water

5. 2. Meteoric water

6. 3. Connate Water
• (Connate means originating together
• This water may have been derived from oceanic or fresh
water sources
• Groundwater encountered at great depths in sedimentary
rocks as a result of water having been trapped in marine
sediments at the time of their deposition.
• Sometimes connate water is referred to as fossil water and
these waters are normally saline. . This is entrapped
brackish water.
• Water in Lathi sandstone is good example of connate
water.
