  • Roughly 70 percent of an adult’s body is made up of water.
  • The first municipal water filtration works opened in Paisley, Scotland in 1832.
  • In 1974, Congress passed the Safe Drinking Water Act to ensure that drinking water is safe for human consumption.  The Act requires public water systems to monitor and treat drinking water for safety.
  • Water is made up of two elements, hydrogen and oxygen. Its chemical formula is H2O.
  • Most of the water on earth—97 percent, to be exact—is saltwater and can’t be used for drinking purposes. Only three percent is freshwater, and most of that is tied up in the polar ice caps and glaciers.
  • More than half of the water we use in the warmer months is used for outdoor irrigation.
  • We need to drink water frequently, but drinking too much water can kill you. Drinking too much water can cause a dangerously low dilution of electrolytes and other minerals in the body, leading to death by “hyper-hydration.” Fortunately, the two most common causes of this condition in healthy individuals can be avoided: long exercise periods where lots of water is consumed with few electrolytes ingested (try a sports drink instead); and water-drinking contests or hazing rituals.
  • A healthy person can drink about three gallons (48 cups) of water per day.
  • At birth, water accounts for approximately 80 percent of an infant’s body weight.
  • There are more than 56,000 community water systems providing water to the public in the United States.
  • Soft drinks, coffee, and tea, while made up almost entirely of water, also contain caffeine. Caffeine can act as a mild diuretic, preventing water from traveling to necessary locations in the body.
  • Pure water (solely hydrogen and oxygen atoms) has a neutral pHof 7, which is neither acidic nor basic.
  • Water has three different states, liquid, solid and gas.
  • The longest river in the world is the Nile River, it reaches 6650 kilometers in length (4132 miles).
  • The second longest river in the world is the Amazon River, it reaches 6400 kilometers (4000 miles) in length.
  • The longest river in the USA is the Mississippi River, it reaches 6275 kilometers in length (3902 miles).
  • The water cycle involves water evaporating (turning into a gas), rising to the sky, cooling and condensing into tiny drops of water or ice crystals that we see as clouds, falling back to Earth as rain, snow or hail before evaporating again and continuing the cycle.
  • Water in the form of ice is found at the polar ice caps of the planet Mars, some scientists have also suggested the possibility of liquid water on the red planet.
  • Water expands as it cools from 4 °C to 0 °C (above 4 °C it does the opposite). In freezing conditions, water has been known to burst water pipes as it freezes to ice.
  • Water is used frequently by firefighters to extinguish fires. Helicopters sometimes drop large amount of water on wildfires and bushfires to stop fires spreading and limit the damage they can cause.
  • Electricity can be created from hydropower, a process that uses water to drive water turbines connected to generators. There are many hydroelectric power stations around the world.
  • Drinking water is needed for humans to avoid dehydration, the amount you need each day depends on the temperature, how much activity you are involved in and other factors.
  • Much more fresh water is stored under the ground in aquifers than on the earth’s surface.
  • Water is sometimes called the “universal solvent” because it can dissolve many substances, including metals (turning steel into rust, for example). In fact, pure H2O is tasteless; many bottled and mineral waters obtain their unique tastes from the minerals dissolved in their source water.
