Water pollution is a major cause of waterborne diseases worldwide, especially in developing countries. Polluted water affects the health of the present generation and affects future generations because of its ongoing effects. In India about 60 percent of the population does not have access to safe drinking water. Especially in India the incidence of birth defects, cancer and skin-related diseases, lungs, brain, kidneys and liver is greater than in any other society. The flow of the river has a profound effect on land use and social and economic fabric. More recently, there has been a growing demand for river water due to cash crops, urban growth and industry in the developing economies. Pollution and health problems are closely linked. Disease-causing microorganisms, known as germs, spread directly to humans. Bacteria are found in many places around the world. Many waterborne diseases are transmitted to humans.Developing, developing and developing countries (LDCs) have been affected by diseases caused by heavy rainfall and flooding. One-tenth of the population uses contaminated water. Health risks caused by water pollution include various diseases such as cancer, diarrhea, respiratory disease, nervous disorders and heart disease.
How Delhi badly affected by water pollution
Delhi Indoor-produced Sewage is the main cause of Yamuna pollution and contributes to 80% of the total pollution dumped into the river. About 90% of sewage from sewage flows into the river untreated. These contaminants include detergents and other chemicals that increase the phosphate content in water leading to foam formation. The same is true of industrial wastewater and sewage dumped into the river without washing it. Only 35 percent of waste disposal costs are treated. Other factors, such as immersion of images, also play a role in pollution. Lead, paris concrete (POP) and chrome paint used in photography also contaminate water after immersion. Not only this, but all the neglected items like polythene bags, decorative items, metal accessories etc. they are also an influential factor.
The Delhi area of the Yamuna River is about 22 km from Wazirabad barrage to Okhla barrage. This incident alone is responsible for 76% of the river pollution but the site is also a major source of green water for the capital. This is estimated to be 70% of Delhi’s water translated into 57 million people.
How Mumbai badly affected by water pollution
The short river that flows through the city of Mumbai has ceased to be interesting for decades. Floating debris began to cover its area, preventing water from appearing and the beaches around its mouth were considered the most polluted in the world 10 years ago. Now, citizens and governments are struggling to reclaim the devastated city of India’s most populous city.Until the end of the 19th century, the Trees River was actually a reservoir of water that only flowed during the monsoon season. Lake Powai dam was built in 1799 and Lake Vihar in 1986; both allowed the Mithi River to dry up during the dry season and controlled violent flooding.
It absorbs four times as much carbon than other tropical forests, and mangroves maintain balance between the land and the environment, acting as a natural barrier against floods and erosion. The 2005 torrential rains, which killed more than 1,000 people in the city, made residents and administrators aware of the fact that the city’s uncontrolled flooding had caused flooding, flooding, and mangroves overpowering wildlife and forming a belt. to protect the island city.
How Chennai badly affected by water pollution
Climate change causes rising sea levels and flooding in some cities around the world as well as droughts and water shortages in others Of Chennai’s 11 million citizens, both. The sixth largest city in India receives an average of about 1,400mm (55 inches) of rainfall per year, more than double the amount entering London and about four times the level of Los Angeles.
Hariharan, a 30-year-old resident of Sriram Nagar, said three people in his area were suffering from diarrhea and vomiting due to water pollution. “Last week, we noticed that the water was getting darker and smelly. Shortly afterward, my wife, cousin, and his wife became ill. We then closed the water supply valves and are now able to use borewell water now, ”he said.
Prior to Sriram Nagar, neighboring roads were already experiencing the problem and many residents did not have to get sick if they were told to close the water valves early, until the problem was resolved, he said. “Furthermore, sewage is mixed with storm water drainage and this needs to be addressed,” he said.
How kolkata badly affected by water pollution
A 2003 report released by the Federation of Consumer Associations (FCA) found that Kolkata’s drinking water was contaminated with human waste. According to the report, 87% of the dams supply water to residential facilities has human waste. There was sewage in 63% of the taps, and 20% of water samples collected from various city hospitals were also found to have water unclean. The study reported that about one fifth of the deep water wells and hand pumps used by the Kolkata Municipal Corporation are polluted with human waste. A former director of the All India Institute of Hygiene and Public Health has blamed ongoing water pollution on a leaky sewage system and abnormal water pressure.
How Bangalore badly affected by water pollution
According to researchers, sewage entering lakes is one of the most common reasons for poor water quality in Bengaluru lakes. The river that once supplied drinking water to the villages outside the city of Bengaluru is now often regarded as faulty as a sewer pipe. The water is now unfit for drinking and the uncontrolled flow of industrial and domestic waste and tons of plastic dumped into the river has made it difficult for people to get close to the river because of the foam and bad smell. The 57-mile-long [57 km] Vrishabha vathi River used to be a picnic spot in the late 1960’s. Due to pollution, the only river from the city of Bengaluru now has another name – Kengeri Mori (Kengeri Gutter).A recent NEERI 2021 report submitted to the Supreme Court also confirms that domestic waste is one of the main causes of pollution in Bengaluru ponds.
Experts say river decay has an impact on the Bengaluru ecosystem beyond the foam and aroma it produces; may affect the quality of groundwater in the areas it passes through. Farmers on the outskirts of the city use this water to grow vegetables that end up on the city dining table.
River erosion began about 50 years ago when industrial areas began to form near river basins – Peenya, Yeshwanthpura, Kumbalagou and so on. Over the years, industrial waste has polluted the river but more recently, more pollution has become domestic waste.
