Advantages of groundwater
http://wiki.answers.com/Q/What_are_the_advantages_of_ground_water
actually Ground Water is free from Pathogenic bacteria(which cause diseases). it does not involve the suspended particles, which make the water turbid, unlike surface water of river or stream which contain a lot of particles in it.
Ground Water requires nearly no treatment for its usage. while surface water requires many process like sedimentation, filtration, disinfection etc. ground water are usually hard i.e it cotains in it calicium ions (and some other Di and Tri valent inos which cause hardness of water) hence ground water provide us an small beneficial amount of calcium. but this water is not good for boilers of industries as this may form a calcium layer(called as scaling) within the boiler and it may brust. although gronud water is good but it may contain a a lot of dissolved solids and metals in it (usually in industrial areas) which may be harmful.
Difference of groundwater and surface water

As you could probably guess, there are some obvious differences in surface water and groundwater quality. But there are more differences than you might have been aware of. Each source of water has a unique set of contaminants; groundwater stores pesticide chemicals and nitrate while surface water contains most bacteria and other microorganisms. Because of the interconnectedness of groundwater and surface water, these contaminants may be shared between the two sources. Neither water source can ever be entirely free from water contaminants.
Groundwater supplies in aquifers below the surface of the Earth are among the nation 's most important natural resources. Ground water is the source of about 40% of the water used for public supply. It provides drinking water for more than 97% of the rural population who do not have access to public
