Water Pollution: Surface and Ground Water

Water is an absolute necessity to our bodies. Similar to the surface of the Earth, our bodies are also mostly made up of water. The normal adult body contains

40-50 quarts of water

! It is essential for various metabolic activities in our body. Hence, the water in our body should be renewed every 10 to 15 days. You are everyday receiving water while consuming foods such as vegetables and fruits. Still, you must drink

at least 6 glasses

of water each day. This enables your body to function properly. As already mentioned, water is the base for all functions of the body.

As we know, water is highly essential to sustain life. Therefore, an adequate and satisfactory water supply should be made available to consumers. Efforts are made to achieve a high-standard of drinking-water quality. Read onto know more about the water pollution of surface and ground water.

Surface Water

As the name implies, this water is found in a lake, river or other surfaces. This is usually not very high in mineral content and many times, it is known as

“soft water”

.Though, it is not the case every time. Surface water is exposed to various contaminating agents like organic materials, algae, industrial wastes, insecticides, pesticides and animal wastes. Even the surface water found in a pristine mountain stream can possibly contain Coliform Bacteria or Giardia from the animal wastes.

Ground Water

This water is trapped beneath the ground. Melting snow, rivers that vanish beneath the ground, rain that soaks into the ground are just a few ways that replenishes the supply of underground water. Ground water may contain all the contaminants found in surface water because of the various sources of replenishment. Along with the contaminants, this water contains dissolved minerals like magnesium and calcium. The water is labeled as

“hard water”

if these minerals are found in higher levels.

Protection from Water Pollutants

The first line of defense is protection of water supplies from the various contaminating agents. To ensure safe and pure drinking-water, source protection is the most suitable method. It should be preferred to treating contaminated water supply to make it suitable for consumption.
