Winding 1,560 miles across northern India, from the Himalaya Mountains to the Indian Ocean, the Ganges River is not a sacred place: it is a sacred entity. Known as Ganga Ma—Mother Ganges—the river is revered as a goddess whose purity cleanses the sins of the faithful and aids the dead on their path toward heaven. But while her spiritual purity has remained unchallenged, her physical purity has deteriorated as India’s booming population imposes an ever-growing burden upon her. The river is now sick with the pollution of human and industrial waste, and water-borne illness is a terrible factor of Indian life. But the threat posed by this pollution isn’t just a matter of health—it’s a matter of faith. There is a saying that the Ganges grants us salvation. This culture will end if the people stop going to the river, and if the culture dies the tradition dies, and the faith dies.
In 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.
As the Ganges brought to life the ashes of Bhagiratha’s ancestors, so all Hindus believe that if the ashes of their dead are deposited in the river, they will be ensured a smooth transition to the next life, or freed from the cycle of death and rebirth. Hindus may travel great distances to scatter the ashes of loved ones in the Ganges. Hindus also believe that the Ganges’ divine waters purify those who immerse themselves in her. It is even said that a single drop of Ganges water, carried by the wind over a great distance, can cleanse a lifetime of sins. In cities along the river, daily dips are an important ritual among the faithful. Many cities are considered sacred and serve as pilgrimage sites: Gangotri, where the river originates from a glacial cave; Sagar Island, where the Ganges drains into the sea. Varanasi, the holiest of cities along the river’s course and the most auspicious place to die; and Allahbad, the site of the most important festival in the Hindu religious calendar, Kumbh Mela.
The 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. 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.
