A grade of 92 is an A at most schools, but for tap water it means that millions of Americans drink water that fails to met federal standards.
How long has that water already been in the system?
In many municipalities, aging water infrastructure is serving fewer people than it was built to accommodate. Out of sight has meant out of mind – but resulting changes in water quality may affect safety.
Hoosick Fall, N.Y. is one of many U.S. communities whose drinking water has been contaminated with PFOA or PFOS.

EPA is moving to regulate two chemicals from a group called PFAS that are contaminating drinking water. A public health expert explains why the agency should take much broader action.
The largest desalination plant in Australia, Victoria’s A$3.5 billion ‘water factory’ can supply nearly a third of Melbourne’s needs.
Sydney and Melbourne are bringing desalination plants back on stream and Adelaide plans to increase its plant's output. Perth depends on desalination. But is it the best way to achieve water security?
A study of drinking water sourced from groundwater in areas of intensive farming and horticulture found nitrate levels are already high and rising.
Nitrate in drinking water has been linked to an increased risk of colorectal cancer. That could have implications for some parts of New Zealand where nitrate levels are high.
Our bodies are pretty good at telling us when we need to drink water.
Most of us get thirsty when we need to drink more water. But there are other tell-tale signs that not all is well.
Many towns in Newfoundland and Labrador have issues with disinfection byproducts created by chlorination.
Chlorine has been used to disinfect drinking water for more than a hundred years. But new alternatives may be safer.

Some observers have blamed recent wildfires on poor forest management, while others point to climate change. In fact, a climate scientist explains, reducing fire risks means tackling both issues.

Drinking water in Australia can be contaminated by natural and manmade processes, especially in communities. Innovation is needed to ensure water is ‘fit for purpose, place and people’.
Volunteers prepare to take flow measurements on Muddy Creek.

When people form local networks to take care of resources such as drinking water, they strengthen their communities. Technology can support these efforts and promote learning and innovation.
On the outskirts of Bangalore, families must piece together drinking water from communal supplies, intermittently available tap water, and "water ATMs".
Access to water – not electricity – can have larger gains for health and well-being.
Providing people with clean drinking water and sanitation is less expensive than grid electrification and it could improve more lives.
Globally consumers are increasingly taking charge of their own drinking water supply.
Unless African cities improve water management many will face severe water problems by 2035.
Elon Musk may be on the hot seat for political donations and slurs against a British cave rescuer in Thailand, but his offer to pay for water filters in Flint, Mich., is laudable.

If Elon Musk can help achieve safe drinking water more quickly for every home in Flint, Mich., then he should be lauded. Water is life.
Toppled road sign for a closed water distribution center in Flint, Mich.
Michigan officials have ended distribution of free bottled water in Flint, but many residents believe the city's water crisis is not over and have lost all trust in government.

Myotis septentrionalis), photographed in Arizona.
Scientists often use animals and plants as indicators to assess whether ecosystems are polluted. Tracking bats, which cover wide areas and need clean water, could become a way to find potable water.
Little Missouri River, North Dakota.
Recent research shows that US rivers are becoming saltier and more alkaline. Salt pollution threatens drinking water supplies and freshwater ecosystems, but there is no broad system for regulating it.
Eight seems like a lot…
We've all hear we should drink eight glasses of water per day, but where did that advice come from, and is it outdated?
The Iguazu Falls in Brazil are part of the Guarani Aquifer, one of the world’s major underground reserves of fresh water. The 8th World Water Forum, part of 2018 World Water Day, is being held in Brazil, home to the most fresh water on Earth.
Water is one of our most precious resources, yet it's in danger. World Water Day reminds us of the need to develop policies and governance to avoid squandering water.
