Class: 2A Water Pollution in the Ganges of India Causes of Pollution Solution to the Pollution References: Human Waste:
It is one of the most densely populated regions in the world. Flowing through 29 cities and about 48 towns, countless people bathe, defaecate and do their laundry in the river everyday. This strains the environment.
Countless tanneries, chemical plants, textile mills, distilleries, slaughterhouses, and hospitals contribute to the pollution of the Ganges by dumping untreated waste into it. Industrial effluents are about 12% of the total volume of effluent reaching the Ganges. Although a relatively low proportion. They are a cause for major concern because they are often toxic and non-biodegradable.
During festival seasons, over 70 million people bath in the Ganges over a few weeks to cleanse themselves from their sins. Some materials like food, waste or leaves are left in the Ganges for ritualistic reasons. Burnt offerings, corpses and
carcasses not properly cremated also are thrown into the river.
The Farakka Barrage was initially built to divert freshwater into the Bhagirathi River, but it increases the salinity in the Ganges River, damaging groundwater and soil along the river. Effects of the Pollution Ganga Action Plan
A program launched by Rajiv Gandhi in April 1986 in order to reduce the pollution. The steering Committee of the National River Conservation Authority reviewed the progress of the GAP and necessary correction on the basis of lessons learned and experiences gained from the GAP phase; 2 schemes have been completed under this plan. A million litres of sewage is targeted to be intercepted, diverted and treated. Phase-II of the program was approved in stages from 1993 onwards, and included the following tributaries of the Ganges: Yamuna, Gomti, Damodar and Mahananda. As of 2011, it is currently under implementation.
Main objective of this plan:
-Have an approach of integrated river basin management considering the various dynamic interactions between abiotic and biotic eco-system http://en.wikipedia.org/wiki/Pollution_of_the_Ganges Understanding the Pollution Let's watch the video below: National River Ganga Basin Authority (NRGBA)
NRGBA was established by the Central Government of India, on 20 February 2009 under Section 3(3) of the Environment Protection Act, 1986.
It also declared Ganges as the "National River" of India.
The chair includes the Prime Minister of India and Chief ministers of states through which the Ganges flows. Supreme Court of India
The Supreme Court has been working on the closure and relocation of many of the industrial plants along the Ganges and in 2010 the government declared the stretch of river between Gaumukh and Uttarkashi an “eco-sensitive zone”. www.youtube.com/watch?v=wb_yDBmRgmU images.google.com http://www.mppcb.nic.in/gap.htm Thank you for your attention! Explore Geography 2 Marine life
Through research it has been found out that most of the waste items thrown into the Ganges have high mercury levels which cause many marine animals to die due to consuming the mercury containing wastes. A strong positive correlation between mercury levels in muscle with food habit and fish length was found. Since mostly fishes die, many fishermen in India will lose their jobs as their are very few fishes to be caught and this would make them poorer than their original state.
An analysis of the Ganges water in 2006 showed that illnesses such as dysentry, cholera, hepatitis as well as severe diarrhea which takes away many children's lives in India. It occurs mostly due to the water-borne diseases which are found in the water. These water-borne diseases are mostly formed due to actions such as washing clothes, bathing and lack of sewage. Since many people use the Ganges for doing these kind of things, it is associated with the formation of water-borne diseases.
Some of the dams being constructed along the Ganges basin will submerge substantial areas of nearby forest. For example, the Kotli-Bhel dam at Devprayag will submerge 1200 hectares of forest, wiping out the river otters and 'mahaseer' (a kind of fish) that are found here. Wildlife biologists in India have been warning that the wild animals will find it difficult to cope with the changed situation. http://en.wikipedia.org/wiki/Pollution_of_the_Ganges#Impact Earth: Our Home 2
