Water pollution occurs when a body of water becomes contaminated, usually by chemicals or microorganisms. Water pollution can cause water to become toxic to humans and the environment.

Water is an essential resource for all life on Earth. If a water source becomes contaminated due to pollution, it can lead to health issues in humans, such as cancer or cardiovascular conditions.

This article explores the causes of water pollution, how it can affect human health, and what people can do to help prevent it.

Data published for first time by Environment Agency shows 27% increase on previous year.

Water companies discharged raw sewage into rivers and coastal waters in England more than 400,000 times last year, Environment Agency (EA) data has revealed.

Untreated human effluent poured into rivers and seas for a total of 3.1m hours via storm overflow pipes that are supposed to be used only in extreme weather to relieve pressure in the sewage system.

A nine-month investigation by the Guardian and Consumer Reports found alarming levels of forever chemicals, arsenic and lead in samples taken across the US by Ryan Felton and Lisa Gill of Consumer Reports and Lewis Kendall for the Guardian

A cleanup of the Xuyen Tam Canal in Saigon proposed 20 years ago never took place, and an unbearable stench assails the thousands of people living around it.

One day in 2001 Nguyen Thanh Duc saw a group of local officials come to his alley. With writing pads and measurement tapes in hand, they walked back and forth, pointing at things and writing stuff down before leaving.

The government has green-lighted a VND2-trillion ($86.35 million) project to supply water to three provinces in the Mekong Delta.

Long An, Tien Giang and Ben Tre provinces will get 300,000 cubic meters of water daily when the project is completed this year, and double that from 2025 onwards.

Water will be drawn from the Tien River, a distributary of the Mekong River, to a pumping station in Cai Be District in Tien Giang, and distributed to the other two provinces through pipelines.

Nanoparticles found in foetal brains and hearts, but impact on human health is as yet unknown

Tiny plastic particles in the lungs of pregnant rats pass rapidly into the hearts, brains and other organs of their foetuses, research shows. It is the first study in a live mammal to show that the placenta does not block such particles.

New technique expected to enable scientists to find accumulated microplastics in humans

Microplastic and nanoplastic particles are now discoverable in human organs thanks to a new technique.

Microplastics have polluted the entire planet, from Arctic snow and Alpine soils to the deepest oceans. People are also known to consume them via food and water, and to breathe them in, but the potential impact on human health is not yet known.

Health impact is unknown but scientists say particles may cause long-term damage to foetuses.

Microplastic particles have been revealed in the placentas of unborn babies for the first time, which the researchers said was “a matter of great concern”.

The health impact of microplastics in the body is as yet unknown. But the scientists said they could carry chemicals that could cause long-term damage or upset the foetus’s developing immune system. The particles are likely to have been consumed or breathed in by the mothers.

One in every eight deaths in Europe can be linked to pollution, according to a new report by the EU's environment agency (EEA).

It said factors such as air and noise pollution, as well as poor water quality and exposure to chemicals, contributed to 13% of all deaths.

The report also noted that poorer communities and vulnerable people were the hardest hit by pollution.

"Strong action is needed to protect the most vulnerable," the agency said.

Using contaminated wastewater from a residential ditch to process bottled water, a facility in Hai Phong has been shut down.

Authorities in the northern city have shut down a facility producing drinking water in Ky Son Commune of Thuy Nguyen District over food safety violations.

Inspectors from Hai Phong’s Health Department found the Liem Son facility owned by Nguyen Van Hue, a local resident, has operated without a permit and sourced water from a ditch running through the commune to process into bottled water sold on the market under the brand Vinalis.
