How old is the water we have today?
The evidence is in Earth's heavy water content, and it shows that our planet's water is 4.5 billion years old.
The water on our Earth today is the same water that's been here for nearly 5 billion years. So far, we haven't managed to create any new water, and just a tiny fraction of our water has managed to escape out into space. The only thing that changes is the form that water takes as it travels through the water cycle.
Five billion people, or around two-thirds of the world's population, will face at least one month of water shortages by 2050, according to the first in a series of United Nations reports on how climate change is affecting the world's water resources.
2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water.
Water on Earth predates the solar system, and even the sun. Some of the water molecules in your drinking glass were created more than 4.5 billion years ago, according to new research. That makes them older than the Earth, older than the solar system — even older than the sun itself.
Summary: Strong evidence for liquid water at or near the Earth's surface 4.3 billion years ago is presented by a team of scientists in the cover story of the Jan. 11 issue of the journal Nature.
In 2016, deep down within a Canadian mine researchers made an ancient discovery: the world's oldest pool of water. At a depth of roughly 3 kilometers (1.8 miles), the water dates to an impressive 2 billion years old. The discovery pushed back the date for the oldest known water by at least 500 million years.
Which of these scenarios is responsible for the majority of water in the oceans is still unclear, but we know that most of the water in the oceans (and on the rest of the planet) is very ancient - on the order of 4 billion years old.
Some scientists think that most of Earth's water came from meteoroids (asteroids become known as meteors when they collide with a planet) that struck the Earth. Nearly 4 billion years ago, during the Late Heavy Bombardment, countless meteors rained down on the Earth and the Moon.
Germs and other contaminants are found in rainwater.
While useful for many things, rainwater is not as pure as you might think, so you cannot assume it is safe to drink.
Which states are most water secure?
Hawaii ranks first in the nation for air and water quality, as well as in the overall natural environment category. Massachusetts places second in this subcategory, followed by North Dakota, Virginia and Florida. Learn more about the Best States for air and water quality below.
No. Boiling seawater does not make it safe to drink because it doesn't remove the salt. Freshwater on the other hand - say from a river - can be boiled to make it safe enough to drink.
While our planet as a whole may never run out of water, it's important to remember that clean freshwater is not always available where and when humans need it. In fact, half of the world's freshwater can be found in only six countries. More than a billion people live without enough safe, clean water.
The drought in California is something we've spoken about in previous articles, but it's important to understand that California is only one of a handful of states running out of water. These states include: Texas, Oklahoma, Arizona, Kansas, New Mexico and Nevada as well.
Unless water use is drastically reduced, severe water shortage will affect the entire planet by 2040. "There will be no water by 2040 if we keep doing what we're doing today".
New research suggests ancient Earth was a water world, with little to no land in sight. And that could have major implications for the origin and evolution of life. While modern Earth's surface is about 70 percent water-covered, the new research indicates that our planet was a true ocean world some 3 billion years ago.
They made observations via the European Space Agency's (ESA) (opens in new tab) Hipparcos satellite and estimated that HD140283 — or Methuselah as it's commonly known — was a staggering 16 billion years old.
The sun, at 4.6 billion years old, predates all the other bodies in our solar system.
Geological evidence also helps constrain the time frame for liquid water existing on Earth. A sample of pillow basalt (a type of rock formed during an underwater eruption) was recovered from the Isua Greenstone Belt and provides evidence that water existed on Earth 3.8 billion years ago.
Water flows endlessly between the ocean, atmosphere, and land. Earth's water is finite, meaning that the amount of water in, on, and above our planet does not increase or decrease.
Was the Earth under water?
Calculations show that Earth's oceans may have been 1 to 2 times bigger than previously thought and the planet may have been completely covered in water.
Not only did some of our water at least apparently survive the infernal conditions of Earth's early years and the moon-forming impact, it might be even older than our planet itself.
The ocean formed billions of years ago.
Water remained a gas until the Earth cooled below 212 degrees Fahrenheit . At this time, about 3.8 billion years ago, the water condensed into rain which filled the basins that we now know as our world ocean.
While the oceans aren't in danger of drying out in the near future, the animation is reminiscent of what the Earth may eventually look like, if CO 2 levels continue to rise. High atmospheric CO 2 in the range of 4,500 to 6,000 parts per million could lead to the evaporation of the Earth's ocean over time.
Evidence shows that life probably began in the ocean at least 3.5 billion years ago. Photosynthesis began more than 2.5 billion years ago—the Great Oxidation Event. But it took hundreds of millions of years for enough oxygen to build up in the atmosphere and ocean to support complex life.
Who discovered the water? It was the chemist Henry Cavendish (1731 – 1810), who discovered the composition of water, when he experimented with hydrogen and oxygen and mixed these elements together to create an explosion (oxyhydrogen effect).
Many scientists believe that RNA, or something similar to RNA, was the first molecule on Earth to self-replicate and begin the process of evolution that led to more advanced forms of life, including human beings.
Yes, it is possible to make water. Water is made of two hydrogen atoms and one oxygen atom. The process to combine hydrogen and oxygen is very dangerous though. Hydrogen is flammable and oxygen feeds flames, so the reaction to create water often results in an explosion.
Freshly melted snow is generally considered to be safe to drink without further treatment, however it should not be assumed that because water is frozen that it is safe to drink. Exercise the same caution for melted Ice as you would for standing water, and if in doubt boil the water for 10 minutes.
Since lightning can travel through plumbing, “it is best to avoid all water during a thunderstorm. Do not shower, bathe, wash dishes, or wash your hands,” the US Centers for Disease Control and Prevention noted. “The risk of lightning traveling through plumbing might be less with plastic pipes than with metal pipes.
Can dogs drink rain water?
As tempting as it may be for your dog, it's important to remember that rainwater is not always safe for your dog to drink. When rainwater hits earth, it comes in contact with several contaminants or chemicals that aren't safe to drink.
Over 90% of the Western US is currently experiencing different severities of drought. However, California is being hit the hardest as it goes through the areas first megadrought in 1,200 years.
New Hampshire
New Hampshire has some of the nation's strictest water quality standards. It's no wonder the state's tap water is so clean and great-tasting.

State regulators in May unanimously rejected a much larger $1.4 billion desalination plant in Huntington Beach, citing the costs of the water, potential risks to marine life and hazards associated with sea level rise and flooding.
The problem is that the desalination of water requires a lot of energy. Salt dissolves very easily in water, forming strong chemical bonds, and those bonds are difficult to break. Energy and the technology to desalinate water are both expensive, and this means that desalinating water can be pretty costly.
“Seawater puts out fire just as well as fresh water, and although seawater is tougher on pump equipment than fresh water, proper maintenance and flushing of the systems would limit their corrosive properties on our pumps,” Capt.

Earth could continue to host life for at least another 1.75 billion years, as long as nuclear holocaust, an errant asteroid or some other disaster doesn't intervene, a new study calculates. But even without such dramatic doomsday scenarios, astronomical forces will eventually render the planet uninhabitable.
Summary: Water is used around the world for the production of electricity, but new research results show that there will not be enough water in the world to meet demand by 2040 if the energy and power situation does not improve before then.
Story at a glance. Coalinga, California, is expected to run out of water by December.
What state has no body of water?
The only state in the US with no natural lakes is Maryland. Although Maryland has rivers and other freshwater ponds, no natural body of water is large enough to qualify as a lake.
Photos of Cape Town in Crisis as the City's Water Runs Out
Cape Town would become the world's first major city to run out of water.
Half of the world's population could be living in areas facing water scarcity by as early as 2025. Some 700 million people could be displaced by intense water scarcity by 2030. By 2040, roughly 1 in 4 children worldwide will be living in areas of extremely high water stress.
There is the same amount of water on earth as there was when the earth was formed. The water that came from your faucet could contain molecules that Neanderthals drank… 4. The overall amount of water on our planet has remained the same for two billion years.
Every living thing on Earth needs water to survive and the water that we drink today is the same water that wooly mammoths, dinosaurs, and the first humans ever drank! Earth only has a certain amount of water and it travels around moving between lakes, rivers, oceans, the atmosphere and the land.
As much as half of all the water on Earth may have come from that interstellar gas according to astrophysicists' calculations. That means the same liquid we drink and that fills the oceans may be millions of years older than the solar system itself.
Water—the main reason for life on Earth—continuously circulates through one of Earth's most powerful systems: the water cycle. Water flows endlessly between the ocean, atmosphere, and land. Earth's water is finite, meaning that the amount of water in, on, and above our planet does not increase or decrease.
Yet the climate models used to predict the climate over the coming decades are not suited to such high temperatures. According to some of these one-dimensional models, the Earth would start to lose all its water to space and turn into a new Venus within a mere 150 million years.
The body requires a lot of water to maintain an internal temperature balance and keep cells alive. In general, a person can survive for about three days without water. Certain factors, such as the amount of water required by an individual body and how it uses it, can, however, impact this.
At its beginning, Earth was unrecognizable from its modern form. At first, it was extremely hot, to the point that the planet likely consisted almost entirely of molten magma. Over the course of a few hundred million years, the planet began to cool and oceans of liquid water formed.
Do we drink filtered pee?
Again, sorry to disappoint, the answer is no. The dissolved salts, ions and molecules, like urea, that are present in urine are too small for backpacking filters and even purifiers to remove.
The Sun formed about 4.6 billion years ago in a giant, spinning cloud of gas and dust called the solar nebula. As the nebula collapsed under its own gravity, it spun faster and flattened into a disk.
The sun, at 4.6 billion years old, predates all the other bodies in our solar system.
