Hello aspirant,

Difference between surface water and groundwater is given below:-

• Surface water is the water which is found on the surface of the earth such as in a river, lake or other surface cavities.
• It is usually not very high in mineral content.
• It is called as soft water due the presence of very less mineral content.

While,

• Groundwater is water the contained in or by a subsurface layer of soil or rock.
• It commonly contains less contamination than surface water because the rock tends to act as a filter to remove some contaminants.
• It is called as hard water due the presence of high mineral content.

Groundwater is contained in wide aquifers and after digging a deep well, it must be drained out of the bottom . In reservoirs, rivers and streams, surface water is drawn into the general public water system by an intake.

In a river, lake or other ground, surface water is present. The water isn't very high in mineral content,

and is usually mentioned as water albeit it's probably not.

Groundwater is water that's trapped in or through a soil or rock subsurface layer. There are some ways

that refill groundwater supplies, including rain that soaks within the soil, underground disappearing

rivers and therefore the melting snow.

The causes liable for water degradation are acid precipitation , sewage and waste water, oil pollutants,

industrial waste, dumping etc.

Hope this helps you

All the best for your future
