The difference is as follows-

• Surface water- It is water found in a river, lake or other surface cavities.Groundwater is water contained in or by a subsurface layer of soil or rock.
• Surface water is usually not very high in mineral content. Groundwater commonly contains less contamination than surface water because the rock tends to act as a filter to remove some contaminants.
• Surface water is called as soft water due to its less mineral content. Due to the minerals picked up while filtering thriugh the rocks, groundwater is typically considered to be hard water.

Some of the factors responsible for water degradation are-

• Dumping
• Sewage water
• Industrial waste
• Oil pollution
• Acid Rain
• Global warming
• Eutrophication.

Hey there!

Groundwater is the water that is found in the large acquifers beneath the ground, the water is mostly present in between the rocks and unconsolidated materials like Sand, Slit, etc.

As far as surface water is concerned, it is found on the ground like in RIvers, lakes, ponds, etc.

There are many factors which degrade the ground water and the surface water

• Ground water maybe degenerated by extensive drilling lowering the water level.
• surface water may be degenerated by pollutions from the factories, chemicals, human waste, etc.
