Unveiling The Hidden Dangers: Understanding Freshwater Pollution

Freshwater pollution originates from many sources, including municipal, industrial and agricultural waste, wastewater and nutrient run-off, power generation, heavy industry, automobiles, and others. Around the world, some 2 billion tonnes of human waste are disposed of in water courses every day. Water pollution can come from a variety of sources, including factories, imperfect water treatment plants, oil pipelines, hydraulic fracturing (fracking) operations, wind, storms, and littering.

Agricultural pollution

Agriculture is the leading cause of water degradation and the biggest consumer of global freshwater resources. Every time it rains, fertilizers, pesticides, and animal waste from farms and livestock operations wash nutrients and pathogens—such as bacteria and viruses—into our waterways.

Around the world, agriculture is the top source of contamination in rivers and streams, the second-biggest source in wetlands, and the third main source in lakes. It’s also a major contributor of contamination to estuaries and groundwater. Severe organic pollution already affects around one-seventh of all river stretches in Africa, Asia and Latin America, and has been steadily increasing for years.

Water pollution can come from a variety of sources. Pollution can enter water directly, through both legal and illegal discharges from factories, for example, or imperfect water treatment plants. Spills and leaks from oil pipelines or hydraulic fracturing (fracking) operations can degrade water supplies. Wind, storms, and littering—especially of plastic waste—can also send debris into waterways.

Around the world, some 2 billion tonnes of human waste are disposed of in water courses every day. Poisoning may be caused by toxins that have leached into well water supplies. Wildlife can also be harmed by contaminated groundwater. Other long-term effects such as certain types of cancer may also result from exposure to polluted water.

Water is uniquely vulnerable to pollution. Known as a “universal solvent”, water is able to dissolve more substances than any other liquid on earth. Without action, the challenges will only increase by 2050, when global demand for freshwater is expected to be one-third greater than it is now.

Industrial and municipal waste

Water pollution can come from a variety of sources, including municipal, industrial and agricultural waste, wastewater and nutrient run-off, power generation, heavy industry, automobiles, and others. Around the world, some 2 billion tonnes of human waste are disposed of in water courses every day. Severe organic pollution already affects around one seventh of all river stretches in Africa, Asia and Latin America, and has been steadily increasing for years. All of that pollution has significant health impacts both on environment and human: 4,000 children die every day from diseases caused by polluted water and inadequate sanitation. Each year, some 1.8 million people (mostly children) are killed by diarrhoea alone.

Poisoning may be caused by toxins that have leached into well water supplies. Wildlife can also be harmed by contaminated groundwater. Other long term effects such as certain types of cancer may also result from exposure to polluted water. Over 97% of all the water on Earth is salty and most of the remaining 3% is frozen in the polar ice-caps. The atmosphere, rivers, lakes and underground stores hold less than 1% of all the fresh water and this tiny amount has to provide the fresh water needed to support the Earth’s population. Fresh water is a precious resource and the increasing pollution of our rivers and lakes is a cause for alarm.

Water pollution can enter water directly, through both legal and illegal discharges from factories, for example, or imperfect water treatment plants. Spills and leaks from oil pipelines or hydraulic fracturing (fracking) operations can degrade water supplies. Wind, storms, and littering—especially of plastic waste—can also send debris into waterways. Thanks largely to decades of regulation and legal action against big polluters, the main cause of U.S. water quality problems is now "nonpoint source pollution," when pollutants are carried across or through the ground by rain or melted snow.

The agricultural sector is the biggest consumer of global freshwater resources, with farming and livestock production using about 70 percent of the earth’s surface water supplies, but it’s also a serious water polluter. Around the world, agriculture is the leading cause of water degradation. In the United States, agricultural pollution is the top source of contamination in rivers and streams, the second-biggest source in wetlands, and the third main source in lakes. It’s also a major contributor of contamination to estuaries and groundwater. Every time it rains, fertilizers, pesticides, and animal waste from farms and livestock operations wash nutrients and pathogens—such bacteria and viruses—into our waterways.

Power generation

Water pollution is a widespread problem that is jeopardizing our health. Around the world, some 2 billion tonnes of human waste are disposed of in water courses every day. Severe organic pollution already affects around one-seventh of all river stretches in Africa, Asia, and Latin America, and has been steadily increasing for years. Water pollution can come from a variety of sources. Pollution can enter water directly, through both legal and illegal discharges from factories, for example, or imperfect water treatment plants. Spills and leaks from oil pipelines or hydraulic fracturing (fracking) operations can degrade water supplies.

Each year, some 1.8 million people (mostly children) are killed by diarrhoea alone.

Oil spills and leaks

Water pollution can come from a variety of sources. Pollution can enter water directly, through both legal and illegal discharges from factories, for example, or imperfect water treatment plants.
