Types Of Water Pollution

Water pollution can draw closer from numeral different sources. If the pollution comes from a single starting place, such as an oil spill, it is called point-source pollution. If the pollution comes from many sources, it is called non point-source pollution.

Most type of pollution has an effect on the immediate area adjoining the source. Sometimes the pollution may have an effect on the surroundings hundreds of miles away from the resource, such as nuclear waste, this is called Trans boundary pollution.

Surface waters are the natural water assets of the Earth. They are found on the peripheral of the Earth’s outer layer and take account of the oceans, rivers and lakes. These waters can become contaminated in a number of ways, and this is called surface water pollution.

Microorganisms that live in water feed on biodegradable substances. When too much biodegradable material is added to water, the number of microorganisms enlarge and use up on the hand oxygen. This is called oxygen depletion.

When oxygen levels in the water are exhausted, relatively harmless aerobic microorganisms die and anaerobic microorganisms set in motion to flourish. Some anaerobic microorganisms are harmful to people, animals and the environment, as they bring into being harmful toxins such as ammonia and sulfides.

A lot of the Earth’s water is found underground in soil or under rock structures called aquifers. Humans often use aquifers as a means to get hold of drinking water, and build wells to access it. When this water becomes polluted it is called groundwater pollution. Groundwater pollution is often caused by pesticide contamination from the soil; this can contaminate our drinking water and cause huge problems.

Microbiological water pollution is more often than not a natural form of water pollution caused by microorganisms. Serious diseases such as cholera come from microorganisms with the intention of living in water. These diseases frequently have an effect on the health of people in poorer countries, as they do not have the amenities to treat contaminated water.

Biodegradable substances are often suspended in water and can cause problems by increasing the amount of anaerobic microorganisms present. Toxic chemicals suspended in water can be harmful to the development and survival of aquatic life.

With a wide variety of types of water pollution, a single action will not be enough to ward off more pollutants. Prevention starts with awareness and continues with a dedicated effort to not only prevent further contamination but also clean up the present pollutants.
