The Ganges River
Report by Amberly Polidor HistoryIn a country where practically everything in nature is venerated, the Ganges is most holy. Considering the magnitude of her life-sustaining force, it’s no wonder: her mighty course from the mountains to the sea creates a river basin 200 to 400 miles wide that supports nearly half a billion people. According to Hindu mythology, the Ganges was once a river of heaven that flowed across the sky. Long ago, she agreed to fall to earth to aid a king named Bhagiratha, whose ancestors had been burned to ash by the angry gaze of an ascetic they had disturbed during meditation. Only the purifying waters of Ganges, flowing over their ashes, could free them from the earth and raise them up to live in peace in heaven. So that the earth would not be shattered by the impact of her descent, Lord Shiva caught Ganges in his hair as she cascaded down from heaven to the Himalyas. Ganges then followed Bhagiratha out of the mountains, across the plains to the sea, where she restored his dead ancestors and lifted them to paradise.
Current ChallengesThe tremendous life that the Ganges supports is also the source of its greatest threat: pollution. The majority of the Ganges’ pollution is organic waste—sewage, trash, food, and human and animal remains. Over the past century, city populations along the Ganges have grown at a tremendous rate, while waste-control infrastructure has remained relatively unchanged. Sewage systems designed near the turn of the 20th century today do little more than channel waste into the river. Some 300 million gallons of waste go into the Ganges each day, and the effects are stunning: recent water samples collected in Varanasi revealed fecal-coliform counts of about 50,000 bacteria per 100 milliliters of water, 10,000% higher than the government standard for safe river bathing. The result of this pollution is an array of water-borne diseases including cholera, hepatitis, typhoid and amoebic dysentery. An estimated 80% of all health problems and one-third of deaths in India are attributable to water-borne diseases. The sacred practice of depositing human remains in the Ganges also poses health threats because of the unsustainable rate at which partially cremated cadavers are dumped. In Varanasi, some 40,000 cremations are performed each year, most on wood pyres that do not completely consume the body. Along with the remains of these traditional funerals, there are thousands more who cannot afford cremation and whose bodies are simply thrown into the Ganges. In addition, the carcasses of thousands of dead cattle, which are sacred to Hindus, go into the river each year. While industrial pollutants account for a smaller proportion of contamination in the Ganges, the health and environmental impacts of toxic chemical waste can be far greater. From the plains to the sea, pharmaceutical companies, electronics plants, textile and paper industries, tanneries, fertilizer manufacturers and oil refineries discharge effluent into the river. This hazardous waste includes hydrochloric acid, mercury and other heavy metals, bleaches and dyes, pesticides, and polychlorinated biphenyls—highly toxic compounds that accumulate in animal and human tissue. Runoff from farms in the Ganges basin adds chemical fertilizers and pesticides such as DDT, which is banned in the United States because of its toxic and carcinogenic effects on humans and wildlife. Damming the river or diverting its water, mainly for irrigation purposes, also adds to the pollution crisis. Rivers need fresh infusions of water to dilute and dissolve pollutants, and water flow is necessary to flush material downstream. In 1985, the government of India launched the Ganga Action Plan, which was devised to clean up the river in selected areas by installing sewage treatment plants and threatening fines and litigation against industries that pollute. Almost 20 years later, the plan has been largely unsuccessful. The Western-style treatment plants simply did not meet the needs of the region. Such treatment facilities are designed for use in countries where the supply of electricity is stable, there’s no season of overwhelming monsoon rains, and the population doesn’t drink directly from the water source. Many Indians blame the plan’s failure on mismanagement, corruption and technological mistakes. A key criticism is that local communities, those most invested in the health of the river, were not included in the planning process. Preservation EffortsIn contrast to the shortcomings of the government’s Ganga Action Plan, the citizen-based Sankat Mochan Foundation, started in Varanasi in 1982, has made great strides toward a lasting clean-up of the Ganges. With a dual identity as Hindu priest and civil engineer, the organization’s founder, Veer Bhadra Mishra, has approached the problem from both a scientific and a spiritual perspective. In collaboration with engineers at the University of California, Berkeley, Mishra has proposed an alternative sewage-treatment plan for Varanasi that is compatible with the climate and conditions of India. The advanced integrated wastewater oxidation pond system would store sewage in a series of ponds and use bacteria and algae to break down waste and purify the water, so it wouldn’t need electricity. Sankat Mochan is currently trying to persuade India’s central government to adopt the plan.
Sankat Mochan’s cleanup program, called Campaign for a Clean Ganga, has achieved tangible results. For example, workers in Varanasi now pick up litter along the riverfront and remove corpses and animal carcasses from the river. Despite the achievements in Varanasi, the clean-up campaign must be a national effort, touching all parts of the river, if it is to be successful. To this end, Campaign for a Clean Ganga launched a program in 2002 to raise national awareness, empower local communities to take charge of environmental issues, and build national coalitions of NGOs, industries and local governments. In March 2003, the program organized the first national Clean Ganga Day in Calcutta, the first in a series of workshops for civic leaders and the general public. Resources
