Water Pollution

Filed Under (Water Pollution) by admin on 10-06-2010

In addition to clean air, all living organisms, animals and plants call for a clean water supply in order to continue to exist. We may think that we contain lots of water but merely a small amount of it is fresh water that we can use and day by day we are polluting our water in the same way we are polluting our air.

When harmful substances such as oil and chemical wastes come in the waterways either through accidents or through being deliberately dumped, they are soon carried away by tides or the flow of the river and are really not easy to remove. As a river makes its way to the ocean, a number of different chemicals can enter its waters. Harmful chemicals can enter our rivers and lakes from any number of sources. For example they can dribble out of dumpsites or pesticides and fertilizers or may draw off from farmlands or they may find their way into manure that is pumped from local towns and cities.

One of the most destructive forms of water pollution is from oil. Oil spills from ships and oil tankers at sea cause overwhelming water pollution and harm flora and fauna. These events receive lots of attention on television and from ecological groups that work towards shielding our mother earth. However these spills only correspond to a small percentage of the total amount of oil that contaminates our water. Tankers dump oil into oceans as part of their custom cleaning, refineries pump oily wastewater into surface water and oil from city streets are washed into storm drains that sooner or later enter our waterways.

When people rinse materials down the drain, flush their toilets or do a load of wash, the wastewater usually goes to sewage treatment plants to be purified. These plants will then remove dirt, eco-friendly materials such as food waste and a number of other pollutants before the water reach our waterways. However, most treatment plants can’t remove all the chemicals that are used in products such as paint thinners or phosphates that are used in many detergents and these substances end up passing right through the sewage treatment plant untreated. Other sources of water pollution include the grime and garbage from the streets that are washed into storm drains. In most areas these storm drains vacant into underground pipes that will sooner or later dump directly into our lakes, rivers and oceans.

People all over the world have realized the collision of human activities leading to the

dreadful conditions of the natural environment. Numerous attempts are already being made on a local, national and worldwide scale. However a lot more needs to be done by each one of us in achieving our undertaking of environment safeguard.

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.

Ways To Control Water Pollution

The crisis of Water pollution is not a new-fangled one. It has been on hand since ages. Clearly the problems linked with water pollution have the capabilities to disturb life at a individual level as well as on greater level for the planet as a whole. Government bodies have approved laws to try to combat water pollution, thus acknowledging the fact that water pollution is without a doubt a serious issue which needs to be addressed at the earliest. But the government single-handedly cannot get to the bottom of this problem. It is up to us to be well-versed, in charge and act in view of facts when it comes to the problems we face with water.

We must become familiar with our local water resources and learn about ways for disposing household wastes efficiently, so that they do not end up in sewage treatment plants that can’t handle them or landfills not planned to accept the dangerous materials.

We must take dynamic participation and straighten out on whether supplementary nutrients are needed before fertilizers are applied and look for alternatives where fertilizers may run off in to surface waters.

We should care for and take care of existing trees and plant new shrubs and trees to put a stop to soil erosion and promote penetration of water into the soil. At an individual level around our houses we have got to keep waste, pet squander, leaves and grass clippings out of gutters and storm drains. These are just a small number of the many ways in which we as humans by taking remedial action against the water pollution problem can help battle water pollution. By being conscious ourselves and educating our younger ones and siblings, we humans can help to battle water pollution.

Global environmental cave in is not to be anticipated. In this fast developing world we need to make sure that the new developed economies do not add to the world’s ecological problems. Politicians must think of sustainable expansion rather than just trade and industry expansion. Although we humans are on familiar terms with this fact, we disregard water for our recreational purposes, such that our drinking water has to the highest degree been affected.

If these measures are not taken into consideration soon by each one of us and water pollution continues, life on earth is going to be affected severely. In short, with the technology that currently exists to combat water pollution, the years of global mistreatment can begin to be inverted. In order to combat water pollution we understand the problems and become a part of the solution.

Urban Ecology

In the city we try to overcome the problems without addressing the real problems. The main problem is our mindset. When we face water shortage at home the only solution we think of is by installing a pump for drawing ground water. We never think as to how groundwater gets collected or even if we know we don’t care.

As a result groundwater table has depleted alarmingly, in the last decade and even when water is found the water is found contaminated. Without allowing replenishment of groundwater we keep withdrawing the underground water. Rather we pave any bare soil with cement concrete that paves water percolation. Around our homes we can easily avoid unnecessary paving of bare soil. But we believe that bare soil will increase dust and dirt around us. If the soil is allowed to remain, in no time, grass will cover the surface. But city people usually end up paving the surfaces especially in front of their homes.

We have created condition in most cities where on long weekends people escape to the countryside to enjoy nature. To achieve peace of mind, we escape from the city. Why should this be so? It is because of the way our cities are developed and our lifestyles.

Whenever it rains, nature intends that some amount of water percolates through the soil to replenish ground water. But in cities it is an obsession to pave every inch of bare soil fro the sake of beautification. The pavements do not allow the water to seep into the ground. It rather accumulates forming puddles and pools.

When streets are well drained, they look dry within minutes of the rain stopping. We appreciate and laud the civic authorities for the excellent designs of the storm water drains. But we forget two basic things which are the outcomes of this design. The area where the rain falls gets drained off without percolation. The entire water is taken through storm water pipes and released in to a nearby stream or river where flood conditions get created where as the city groundwater depletes. So we create scarcity of water in one place and excess supply of water in another place. Rather if our houses and offices had systems to harvest rainwater, it would solve the twin problems- the groundwater will get replenished and at the same time flooding of streams and rivers can be avoided. There is no need to feel helpless…..just need to take some actions to address the issue.

Adverse Effects Of Water Pollution

The effects of water pollution are increasingly drawing the environment and human beings as well to feel the pinch of polluted water. Water pollution affects our, rivers, lakes, oceans and drinking water. With the increase in population and industrial development, demand for water has increased.

Water is getting polluted when chemicals, harmful contaminants are detected Human beings have the most crucial impact on our water resources. Moreover the need for water is far more in the society today than the quantity of water available. Some water pollution effects show up immediately where as others don’t show up for months or years.

The water pollution has damaged the food chain and is very important for the food preparation of plants through photosynthesis When Filth is thrown in water the toxins travel from the water and when the animals drink that water they get contaminated and when humans tend to eat the meat of the animals is infected by toxins it causes further damage to the humans.

Infectious diseases such as cholera and typhoid can be contracted from drinking contaminated water. Our whole body system can have a lot of harm if polluted water is consumed regularly. Other health problems associated with polluted water are poor blood pressure, vomiting, skin lesions and damage to the nervous system. In fact the evil effects of water pollution are said to be the leading cause of death of humans across the globe.

Pollutants in the water alter the over all chemistry of water, causing a lot of changes in temperature. These factors overall have had an adverse effect on marine life and pollutes and kills marine life. Marine life gets affected by the ecological balance in bodies of water, especially the rivers and the lakes.

Water pollution effects have a huge impact on the health of an individual and the environment as a whole. The balance between the nature and the humans can be protected and should be maintained .But t it will take efforts on all fronts by each and every individual from the society to prevent and eliminate water pollution locally and globally.

Causes Of Water Pollution

Farmers time and again use chemicals to get in the way to bug infestations or other diseases from damaging or ruining the crops. Farmers also make use of chemicals to smooth the progress of the growth of the crops. Either ways these chemicals percolate in to the ground water or run off in to the lakes, rivers and creeks causing water pollution. The farmer’s land which is irrigated and treated by means of chemicals in the form of fertilizers or pesticides is a most important contributor to water pollution.

Industrial processes generate poisonous waste containing heavy chemicals. When heavy metals filter into the water, they are lethal to marine life. Shellfish and fresh fish are staple set of choices items for people all around the world. Humans are polluted by the heavy metals ingested by the fish and the shell fish causing physical condition problems and sometimes death. The heavy metals in the water have also been associated to severe birth defects, a damaged or covered up immune system, cancer, fertility problems and developmental troubles in kids.

The building industry is also for the most part at fault for contaminating a huge part of our water resources with cements, lubricants, plastics and metals. Rivers and lakes are also polluted from silts and remains that run off in to the rivers and lakes from a range of building sites.

Ground water pollution occurs when chemicals, debris, garbage, oil or other damaging contaminants enter the ground water supply overtime. Major upheavals such as storms, earthquakes, acid rains, floods and volcanic eruptions have been known to interrupt the ecological system and contaminate the earth.

The growth of algae owing to food items, urea in the water source is also a cause of water pollution. When an alga grows in water it uses more than its fair distribute of oxygen, causing other living organisms in the body of water to suffer. The course of action of pollution begins with tiny organisms that pass through the food chain through clams, birds, marine creatures and in due course through humans. These types of algae are known to be poisonous for the reason that they are measured to be causing fatalities in humans. Even over-growths of non-toxic type of algae can in actual fact block the sunlight from entering the water’s surface, which makes it difficult for marine life to find food, sooner or later causing death.

Littering on the land or on the water is an additional source of water pollution. Debris tossed on the land in due course makes its way into the storm drains and then returns to surface water. Ships and boats discharging human wastes and chemicals into the water directly are cleanly speeding up the procedure of water pollution.
