Polluting The Water Facts, Effects of Water Contaminations
Do you aware what’s the reason for polluting the water? How is the water being polluted? Water can be contaminated various ways. It means that one or more substance has built up to such an extent which causes problems for humans as well as animals.
Lakes, oceans, rivers and other inland water may be cleaned up a particular amount of water by dispersing it harmlessly. If you pour a cup of black ink into a river, the ink disappeared for the great volume of water in the ocean.
Still, then the ink will remain there, but contramination is very low which you cannot see. The chemicals in such ink would not create any problem. If you pour gallons of ink in a river within few seconds by a pipe, the river turns into black rapidly.
The chemical has a great effect on the water within a short period. It also affects the health of the animals, plants, and humans who are dependent on rivers.
Thus, water pollution is all about quantities: So how much of polluting substance is given or how much big volume of water is released into.
A little amount of chemical has little impact on water, but a small quantity of toxic chemical have great impact pumped into a river and lake, where less clean water to disperse it.
What is Water Pollution?
People say another name of water is life. This is really true. About 70% of the water of the earth is covered with water. Surely this is the greatest resources.
As a student, you have to know the various types of conserve water. Water is greatly used in human processes and chores. This is very important for both industrial and domestic purposes.
We fail to pass a single day without water. If we closely notice the resources of water, it gives us a shock.
Our sources of water are being infested with waste coming out from floating plastic bags or from chemical waste.
The contamination of water resources is known as water pollution. So the abuse of ponds, lakes, reservoirs, rivers, and oceans is water pollution.
The discharge of pollutants is responsible for water pollution. It may be direct or indirect.
Water pollution is a significant concern in the whole world. This is a very appealing problem. Pollution is powerful enough to lead the world to the way of destruction. All pollutants dissolve in water.
So it is polluting severely every day. Vegetation and organisms which survive in the water like amphibians are severely affected by water pollution. Many people face death from water pollution or consumption of water.
In 2008 nearly 1000 children died in India from diarrheal sickness for consuming polluted water. This number has increased rapidly in the last five years.
It is true that human-made and natural activities mainly pollute water. Earthquakes, volcanic eruptions, Tsunamis etc. are indicated as alter water and contaminate it. It also affects the ecosystem which remains under water.
What are the effects of water pollution?
Some people trust that water pollution is inescapable result of people’s activities. They show logic that there is no way to avoid water pollution if we use cars, oil, ships, cities, factories and coastal resorts.
Some levels of water pollution are must for such factors. In another way, pollution is must and people have to put up with it if they want to progress. Luckily all people don’t agree with this view.
People have woken up the problem of pollution which brings of their costs. Many economic benefits come out of pollution.
Suppose, think about oil spills. This happens when tankers are made very poorly to ply on the sea. When an accident happens, oils seep from the tankers and mixes with water.
Sometimes oil washes up on closely nearby beaches. It devastates the ecosystem and affects tourism. People who bear the cost of the spill aren’t responsible for this activity for the first time.
Everyone who puts gasoline into a car or uses any petroleum-fueled transport- add this problem. Therefore oil spill is a problem for everyone. It is a problem for people who live near the coast and tanker operates.
Sewage water is another example by which people can affect more. Sewage discharge in coastal water may wash up on beaches and create a health hazard.
People bath and surf in water and fall ill when they swallow contaminated water. There are other harmful effects of sewage water.
This water poisons shellfish which grow close to the shore. People who eat this shellfish suffer from paralytic shellfish poisoning.
It is forbidden to catch shellfish in many seashores for severely polluted with the toxic chemical or sewage wastes that are discharged from strictly land.
People live in an environment. But this environment is polluted in many ways. So pollution is a matter for people. The environment isn’t far from our lives.
The surrounding is the only thing which surrounds us and ensures health for us. Destruction of environment eventually reduces the standard of own lives. So prevention of pollution provides a right situation for us all.
Sources of Water Pollution
There are many types of water pollutions. The primary 2 sources of water pollutions are Point and Non-Point.
The point means the pollutant which remains within a single source. Emission from factories is an example of the point.
On the other way, Non-Point means pollutant emitted from lots of sources. After the rain, contaminated water travels through different regions. It may be known as a Non-Point source of pollution.
What are the causes of water pollution?
Millions of people on the planet think that disposing of sewage waste is a great problem. This is the statistic of the World Health Organization that about 780 million people have no chance to drink safe water.
About 2.5 billion people do not have well sanitation management. Though there have been lots of improvements in securing access to clean water. In the last decades, little improvement has been seen in the sanitation sectors.
Sewage disposal affects the environment of people and causes water-related diseases like diarrhea. It kills 760000 children under five every year. In the developed countries people use flush toilets which carry sewage waste hygienically and rapidly away from the homes.
In theory, sewage is completely natural substance which must be broken down without any harm to the environment. Ninety percent of sewage is water. In sewage, there are various kinds of chemicals.
People collect plastic, paper, and some other wastes from the pharmaceuticals. If people become sick with viruses, the sewage they make carries the viruses for the environment. It may catch illness like typhoid, hepatitis, and cholera from sea and river water.
Only a few statistics explain the scale of the problem which comes from wastewater. Almost half of the oceans are polluted mainly by wastewater and sewage.
The world produces five to ten billion tons of industrial waste every year most of which are thrown into oceans, rivers, and other waterways. In the US around 4000,000 factories take clean water from rivers.
Recently a great improvement occurs in wastewater treatment. Since 1970, in the US, the Environmental Protection Agency EPA has invested about seventy billion to improve water treatment plants in 2015 serve around 88% of US population. Another 271 billion still need an upgrade as well as update the system.
Factories are the important points of water pollution. But it is true that ordinary people pollute a lot of water from nonpoint sources. By this way, normal water becomes polluted water in the first place.
Everyone pours chemical in the toilets or the drain. Besides, washing machine and dishwashers pollute our oceans and rivers. We also use pesticides in our garden.
From highway run off a great amount of toxic pollution enters the water. Normally highways are covered with toxic chemicals and cocktail. Everything from brake fluids and spilled fuel worn tires and exhaust emission.
When it rains they get mixed with rivers and drains. Heavy rains summer storm brings this chemical into rivers and ponds. So a huge amount of fish faces death overnight.
Some highway runoff goes into the drain and other pollute groundwater or accumulates in the land next to the road, makes it very toxic as the year passes by.
Detergents are mild substance. If you see it from the other angle, you will see opposite result. The opposite side of the spectrum is very poisonous chemicals like polychlorinated biphenyls.
Once they are greatly used to manufacture electronic circuit boards. Now people know the harmful effects of it. So it is prohibited to use in many countries of the world.
An estimated half million tons of PCBs are discharged into the environment during the twentieth century. They are brought there by the oceans, thousands of miles far from where they entered the environment.
Though the PCBs are elaborately banned, the effects remain for decades as they remain in the environment for a long time except breaking down.
Another type of pollution may occur for some heavy metals like mercury, lead, and cadmium. Once the lead is used in gasoline for some restricted countries in the world. Cadmium and Mercury are still using to make batteries.
In the present days, a highly toxic chemical named tributyltin is being used to save the boats from ravaging effects of the ocean. Ironically, TBT is known as a pollutant: people are using this to save the boat from damage, but they are polluting the water in the sea.
The historic heavy metal pollution happens in the ocean in 1938 when a Japanese factory emitted a great amount of mercury metal to Minamata Bay, having the fish stocks there.
Many people ate the fish and became poisoned around 2000. Hundreds of people became dead and were disable also many.
People become aware of radioactive waste with more alarm- for many good reasons. Having high concentration it may kill, but with a lower concentration, it may cause cancers and some other illnesses.
There are two factories in Europe which are the biggest sources of radioactive pollution. They reprocess the waste fuel from the nuclear power plants: Cap La Hague to the north coast of France and Sellafield to the North West coast of Britain. Both of them discharge radioactive wastewater into the sea. The ocean currents carry it around the whole world.
A country like Norway that is situated in downstream of Britain gets good doses of radioactive pollution from Sellafield.
The government of this country complains again and again that Sellafield increases the radiation level along the coast by six to ten times. Both Norwegian and Irish governments are going on to press for the plant’s closure.
If you think about ocean pollution, great black oil slicks spring to your mind. The spectacular accidents represent a small fraction of all the pollution going into the oceans.
Thinking oil by itself, tanker spill is not very important as they seem to. Only twelve percent of oil which enters into the ocean comes from tanker accident.
Other 70% of pollution occurs for pouring down drains on land and from routine shipping. What makes tanker spills very destructive is the sheer quantity of oil comes from the concentration of oil they produce in 1 much-localized part of the marine environment.
The biggest oil spill happens in the recent years when the tanker Exxon Valdez breaks up in Prince William Sound in Alaska in 1989. About twelve million gallons of oil are releasing into pristine wilderness.
It is sufficient to fill your dwelling rooms 800 times more. It is thought that marine animals are killed in the spill from about 1000 sea otters and 34 thousand birds to as many as 2800 sea otters and 250000 seabirds. Several billions of herring eggs and salmon are believed to face the destruction.
As you have taken part in community bleach cleaning, you know well that plastic is the common element that washes up with the waves. It has three reasons: plastic is the very common material used to make most all kinds of manufactured objects from clothing to the parts of automobiles.
It floats easily and very light, so easy to travel enormous distance across the oceans. Maximum plastics are not biodegradable meaning that plastic can survive in the marine environment for a long time. Plastic can survive for up to 400 years, and the plastic fishing line may long for up to 600 years.
Plastics are not so poisonous to the toxic chemicals they do not create a major hazard for fish, seabirds, and other marine creatures. Suppose plastic fishing line, as well as other debris, may strangle or choke fish.
It is true that about half of the world’s seabird species are likely known to eat plastic residues. A study has done on 450 shearwaters in the North Pacific which indicated that about eighty percent of the birds are found to have plastic residues in their stomachs.
At the beginning of the 1990s, marine scientist Tim Benton gathered debris from two km length of the beach to the isolated Pitcairn Islands in the South Pacific.
His study gathered about one thousands of pieces of garbage having 268 pieces of plastic, seventy-one plastic bottles and two dolls heads.
