Causes of Water Pollution in River Yamuna





River yamuna, an important river quite like the Ganges, is equally heavily polluted.
 It has several and large industrial cities on its banks like Yamuna nagar, a few cities in Haryana like Shonepat, Paanipat, New Delhi, city of Agra and ofcourse Mathura.
It’s a known fact that the water of river Yamuna is not good enough for even bathing, as far drinking is concerned it unthinkable, more-so  with the latest central pollution control board report, will definitely make us think again about this problems as the river is full of excreta and the river once revered is nothing more than a glorified drain.

According to the stipulated standards the water could be made potable with treatment if faecal coliform which is lesser than 500 mu per 100 mL and considered for the purpose of bathing if the number is less than 5000 mu per 100 mL. 
Faecal coliform are bacteris that orioginate in excreta and these levels have reached as high as 1.8 crore per 100 mL. 

Considering drinking water with no known treatment methods by using disinfectants should not have a coliform count more than 50 mu per 100 mL and must have a dissolved oxygen of 6 mg per liter of water. 
The total load of discharged pollution through 18 drains in river yamuna during the last decade is close to almost three thirty tonnes per day.
The drains basically are meant to used for storm water and also the over discharge planned out as per river basin system. 

But presently the high drains are getting used for carrying both sewage which are either treated or untreated as well as industrial effluent along with storm water.
In recent times everyday approximately 2000 million liters of waste and 132 metric tonnes of BOD are discharged into river yamuna form Delhi through 25 drains.
Domestic sector is the main source of water pollution in terms volume and everyday approximately 1700 million waste water is discharged from domestic sector and 300 million liters from industrial sector.

The increase in the pollution has resulted in increase in the generation of domestic waste water from 967 million liters per day in 1977 to 1700 million liters in 1996. 
The capacity for treatment of domestic waste water has increased from 450 million liters per day.
In term of percentage of waste water treated to generated the increase is from 46 percent to 75 percent.

Apart from the sewage from municipality, huge amount of diversified industries like the paper and pulp, factories of sugar, skin tannery, small and big steel plants,various chemicals, different types rubber factories, usual glass and enginnering, the plastics and ofcourse the food processing directly discharge their wastes into it. 
The pollution studies so far made on these water bodies reveal that the water bodies which are linked with human population, rapidly get polluted due to run off, direct human activity and sewage discharge. 
The bodies of water, which remain away from popullation get polluted only slowly through natural sources.  
Tourists activities remain to be a significant source of water pollution as both sewage and infestation by water plants.

Question:Hello all i want to know about what kinds of disaster river pollution can cause in particular i mean the yamuna river what kinds of disasters can its over-pollution cause???

Answers:Any pollution can cause change. One part cyanide in ten million parts water will affect fish and its more common than you might imagine. In places trout have changed gender because of the hormones in contraceptive pills. Oily materials floating on the surface stop surface breathing creatures from breathing, that includes mosquito lava so not always a bad thing. BUT, take away those bugs and the animals that feed off them have a harder job finding food. The food they do find will also have the oily materials in them. That can do anything from kill or affect the fetility of the larger animal/fish. Detergents used to cause all sorts of problems with algae growth but that's controlled in many areas. And don't think those lovely clean streams you see in pine forests are pollution free either. The acid pine needles leeches aluminum from the soil and then gets washed in to the stream. It then acts as a 'floculant', making the solids drop to the bottom of the stream.....giving clear (but mostly dead) water There are rivers in the US where is was dangerous to touch (yes touch). That's rare now. Pollution is still bad in many places but we rarely see the success stories....and there are many.

Question:i can not find anything online about any type of Factory or buisness very close to the cuyahoga river in Cleveland Ohio. I need to write a 2 page report on it and i cant even find a topic or a Factory that might cause pollutants to get into the water. Like I just need some ideas as to what Companies I can choose from. Thanks I can take care of the rest how do strip clubs cause pollution in the Cuyahoga River?

Answers:I don't know of any companies dumping directly into the river But Strip Clubs cause pollution because drunks wander outside and urinate directly in the river. Right ?

Question:River Yamuna (tropical India) gets extremely polluted near my home town- Dissolved oxygen drops to ZERO- killing aqua fauna. water levels in the river vary hugely- from about 100 ft deep in monsoons to just above 1 ft in dry seaon. highly corrupt and ineffective pollution control authorities unable to rein in the pollution despite drains being provided with effluent treatment systems. I feel that some mechanical/natural aerators within the river stream - which do not require external energy supply could be a long term - low cost solution. Any suggestions???

Answers:why don't you have some kind of park. where you can have a park with a lot of small ponds. So you can probably start off by having a primary pond which has dirty river water and goes to another pond that has filters to trap plastic and so on. then the next pond will have the same filtering technology so that way after the long process, you will end up with filtered water. The only problem is sludge build up. IF you want a good example, try look at Centennial park Sydney. The start of the flow is the highest and has a lot of filters such gross pollutant traps for plastics and so on. the next pond has less visible trash but still has damaging pollution. the pollution will turn into sludge and clean water will go to the next pond. the same process occurs again and again and when the process is done, you have cleaner water. this makes a community because there is a park and it acts as a filter. This is the low cost version. the alternative could be having a sewage treatment plant. primary, secondary, and tertiary process included. this is bulky and not appealing to having a community and it's expensive. A park with several ponds might do the trick.

Question:causes of a dirty river

Answers:1.Stop discharge of pollutants into river immediately and divert them to a wastewater treatment plant for reducing the level of pollutants to the acceptable levels 2.Arrange to increase the flow in the river by diverting rain water to river to increase the dilution factor which will bring down the existing pollution level in the river 3.Provide sanitary arrangements along the river bank to prevent discharge of human excreta/body wastes 4.Arrange for solid waste management to prevent further disposing of solid wastes into river 5.Try to increase the dissolved oxygen level in the river water to encourage aquatic life in the river water

River Pollution Crisis in Bangladesh :In Bangladesh, pollution levels in the main rivers of Dhaka have reached a crisis point, becoming biologically dead. And the people who depend on those rivers are left, dry, literally. Dhaka's lifeblood is dying. The Buriganga river, one of the four around Bangladesh's capital, is now one of the most polluted in the world. Twelve million people depend on it for drinking, fishing and carrying trade goods. [Kashem Ali, Resident Living Next to River]: "All the waste, poisonous chemical and acids from the clothes get released into this canal and that leads to the river. This pollutes the water, and cause serious health hazards, mostly skin diseases." Heavy metals such as mercury and cadmium from the many factories along the river banks have penetrated the ground water. Pollution levels in the river have risen to such an extent that the water is no longer fit for livestock to drink. A World Bank study says 1.5 million cubic meters of waste is pumped into the city's rivers every day from 7 thousand industrial units. [Khaja Minnatullah, Environment and Water Management Specialist]: "In a sense the level of contamination is one of the highest probably in the world now, and we call these rivers as biologically dead." Some residents of Dhaka still try to make a living from the polluted river. Families collect rubbish from the river to sell. [Jashimuddin, Resident Living Next to River]: "At this time of the year there is a water crisis, we can't take a bath, the smell is so bad. We ...

troubled Waters New River :www.CalexicoNewRiver.org Troubled Waters- By California Connected The New River holds the dubious distinction of being called North America's most polluted river. It starts in Mexicali, Mexico, flows past homes in the California border town of Calexico and winds up in the Salton Sea. It is made up of 70% waste material and contains raw sewage, disease-causing bacteria, heavy metals and toxic chemicals. It is so dangerous that Border Patrol agents are not required to go in the river to stop illegal immigrants who use it as a "safe" crossing point. Much of Calexico's largely Spanish-speaking population is made up of new immigrants with little political or financial power to do something about the problem. The Calexico New River Committee is trying to push a multi-part project to encase, clean, and treat the river. CalEPA has made them one of six environmental justice pilot projects, but the project has a long way to go. How do you go about cleaning up a mess this big when you are a small, rural, immigrant town with little or no money? And how thirsty must this state be for water agencies to actually WANT the water (if you can call it that) from this river? www.CalexicoNewRiver.org
