The Ganges River, also called Ganga, is a river located in northern India that flows toward the border with Bangladesh. It is the longest river in India and flows for around 1,569 miles (2,525 km) from the Himalayan Mountains to the Bay of Bengal. The river has the second greatest water discharge in the world and its basin is the most heavily populated in the world with over 400 million people living in the basin.
The Ganges River is extremely important to the people of India as most of the people living on its banks use it for daily needs such as bathing and fishing. It is also significant to Hindus as they consider it their most sacred river.

Course Of The Ganga:

The headwaters of the Ganges River begin high in the Himalayan Mountains where the Bhagirathi River flows out of the Gangotri Glacier in India's Uttarakhand state. The glacier sits at an elevation of 12,769 feet (3,892 m). The Ganges River proper begins farther downstream where the Bhagirathi and Alaknanda rivers join. As the Ganges flows out of the Himalayas it creates a narrow, rugged canyon. The Ganges River emerges from the Himalayas at the town of Rishikesh where it begins to flow onto the Indo-Gangetic Plain. This area, also called the North Indian River Plain, is a very large, relatively flat, fertile plain that makes up most of the northern and eastern parts of India as well as parts of Pakistan, Nepal and Bangladesh. In addition to entering the Indo-Gangetic Plain at this area, part of the Ganges River is also diverted toward the Ganges Canal for irrigation in the Uttar Pradesh state.
As the Ganges River then flows farther downstream it changes its direction several times and is joined by many other tributary rivers such as the Ramganga, Tamsa and Gandaki rivers to name a few. There are also several cities and towns that the Ganges River passes through on its way downstream. Some of these include Chunar, Kolkata, Mirzapur, and Varanasi. Many Hindus visit the Ganges River in Varanasi as that city is considered the holiest of cities. As such, the city's culture is also closely tied into the river as it is the most sacred river in Hinduism.
Once the Ganges River flows out of India and into Bangladesh its main branch is known as the Padma River. The Padma River is joined downstream by large rivers like the Jamuna and Meghna rivers. After joining the Meghna it takes on that name before flowing into the Bay of Bengal. Prior to entering the Bay of Bengal however, the river creates the world's largest delta, Ganges Delta. This region is a highly fertile sediment laden area that covers 23,000 square miles (59,000 sq km).
It should be noted that the course of the Ganges River described in the above paragraphs is a general description of the river's route from its source where the Bhagirathi and Alaknanda rivers join to its outlet at the Bay of Bengal. The Ganges has a very complicated hydrology and there are several different descriptions of its overall length and the size of its drainage basin based on what tributary rivers are included. The most widely accepted length of the Ganges River is 1,569 miles (2,525 km) and its drainage basin is estimated to be about 416,990 square miles (1,080,000 sq km).

Population Near the Bank Of Ganga River:

The Ganges River basin has been inhabited by humans since ancient times. The first people in the region were of the Harappan civilization. They moved into the Ganges River basin from the Indus River basin around the 2nd millennium B.C.E. Later the Gangetic Plain became the center of the Maurya Empire and then the Mughal Empire. The first European to discuss the Ganges River was Megasthenes in his work Indica. In modern times the Ganges River has become a source of life for the nearly 400 million people living in its basin. They rely on the river for their daily needs such as drinking water supplies and food and for irrigation and manufacturing. Today the Ganges River basin is the most populated river basin in the world. It has a population density of about 1,000 people per square mile (390 per sq km).

Pollution in Ganga:

Industrial practices in India also have little regulation and as the population grows these industries do as well. There are many tanneries, chemical plants, textile mills, distilleries and slaughterhouses along the river and many of them dump their untreated and often toxic waste into the river. The water of the Ganges has been tested to contain high levels of things like chromium sulfate, arsenic, cadmium, mercury and sulfuric acid.

Despite the religious significance and daily importance of the Ganges River for the people of India, it is one of the most polluted rivers in the world. Pollution of the Ganges is caused by both human and industrial waste due to India's rapid growth as well as religious events. India currently has a population of over one billion people and 400 million of them live in the Ganges River basin. As a result much of their waste, including raw sewage is dumped into the river. In addition, many people bathe and use the river to clean their laundry. Fecal coliform bacteria levels near Varanasi are at least 3,000 times higher than the what is established by the WHO.
