Is your community’s water tainted with lead? The data might not have been reported.
Flint's highest recorded lead levels were typical for water systems that report problems. What's more, a number of cities haven't reported their lead issues.
The global water crisis means scientists face urgent decisions on how to foster water managers’ care. Here, the North Saskatchewan River with the Rocky Mountains, Banff National Park.
Imagining how to increase water managers’ empathy for others in a holistic way is critical for our human and planetary future.
Cold water shock explained.
Governments have been reluctant to work towards increased overbank flows, but the Basin needs it to boost its resilience.
The Murray-Darling Basin might not survive future climate change shocks without changes to the plan.
Waves on Lake Superior crash against the Duluth, Minn. waterfront Sept. 10, 2014.
Over the past 20 years, Great Lakes water levels have gone from sustained multiyear lows to multiyear highs. Climate change is accelerating the transition between dry phases and wet phases.
Everything in an animal’s body is made out of cells. And these cells need chemicals, such as salt, in and around them to work properly. The chemical balance needs to be just right.

Some animals, such as ghost shrimps can even cope with water that is saltier than normal seawater. It's all down to evolution.
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.
Melbourne’s water supplies are running low after years of drought.
Water in Sydney is far cheaper than in Melbourne, and residents take full advantage of it.
Many people worry that even properly treated wastewater will make them ill if they wash with or drink it.
Wastewater reuse suffers from a perception problem.

Lead contamination is not just a problem for Flint, Michigan. It is an issue in many regions. One epidemiologist figured out how to measure past lead exposure using treasured biological samples.
The more fuel there is for the fire to burn, the bigger the fire. Leaves, trees and grass fuel the fire.
Bushfires require three key ingredients to ignite: heat, fuel and oxygen.
Asteroids known as ‘S-type’ contain a lot more water than we thought.
New research demonstrates that the solar system is wetter than we thought.
Planetary scientists believe that Earth was formed by the conglomeration of meteorites and comets – which also brought water.
The source of water on Earth, the Moon and planets in our solar system is hotly debated. Some in the planetary science community argued that it came from asteroids and comets. Now they have proof.

Leonardo's obsession with water flowed through his technical work, his art and his scientific ideas.
Lessons learned from the threat of Cape Town’s “Day Zero.”
Cities need to pay attention to how extreme weather events effect their resources.
Farmer-led irrigation comes in many different shapes and forms.
The green revolution: small-scale, informal irrigation is expanding in Zimbabwe and small scale farmers are leading the way.
You don’t have to quit bread, but make sure it’s wholegrain.

Since 2008, Landsat data has been free for the world to use, spurring new applications and scientific research. But that door could soon slam shut.
The Periodic Table of the Elements.
Hydrogen is the first element in the periodic table and essential for life on Earth. It may also be key to shifting away from fossil fuels toward clean sources of energy, but challenges remain.
