Water is generally classified into two groups: Surface Water and Ground Water. Surface water is just what the name implies; it is water found in a river, lake or other surface impoundment. This water is usually not very high in mineral content, and many times is called “soft water” even though it usually is not. Surface water is exposed to many different contaminants, such as animal wastes, pesticides, insecticides, industrial wastes, algae and many other organic materials. Even surface water found in a pristine mountain stream possibly contains Giardia or Coliform Bacteria from the feces of wild animals, and should be boiled or disinfected by some means prior to drinking.
Ground Water is that which is trapped beneath the ground. Rain that soaks into the ground, rivers that disappear beneath the earth, melting snow are but a few of the sources that recharge the supply of underground water. Because of the many sources of recharge, ground water may contain any or all of the contaminants found in surface water as well as the dissolved minerals it picks up during it’s long stay underground. Waters that contains dissolved minerals, such as calcium and magnesium above certain levels are considered “hard water” Because water is considered a “solvent”, i.e., over time it can break down the ionic bonds that hold most substances together, it tends to dissolve and ‘gather up’ small amounts of whatever it comes in contact with. For instance, in areas of the world where rock such as limestone, gypsum, fluorspar, magnetite, pyrite and magnetite are common, well water is usually very high in calcium content, and therefore considered “hard”.
Due to the different characteristics of these two types of water, it is important that you know the source of your water — Surface or Ground. Of the 326 million cubic miles of water on earth, only about 3% of it is fresh water; and 3/4 of that is frozen. Only 1/2 of 1% of all water is underground; about 1/50th of 1% of all water is found in lakes and streams. The average human is about 70% water. You can only survive 5 or less days without water. – Information obtained SoftWater.com

Here are just a few amazing facts about water and the treatment of it:
- A quarter of the worlds population is without safe drinking water.
- Less than 1% of the water treated by public water systems is used for drinking and cooking
- In the time it took you to read these first three facts another child has just died in the developing world from unsafe drinking water.
- According to NASA the natural rotation of the Earth has been altered slightly by some 10 trillion tons of water stored in reservoirs over the past 40 years.
- Water makes up 75% of the human brain. 75% of trees are also made from water!
- Water expands by 9% when it freezes, making it less dense, which is why ice floats on water.
- You could live for a month without food, but you would be dead after a week without water!
- In the United States forty-eight million people receive their drinking water from private or household wells.
- 500,000 tons of pollutants pour into lakes and rivers each day in the US alone.
- Once it evaporates, a water molecule spends around ten days in the air.
- If you donated $15 to providing Safe Water that would be enough to give one person safe water for life.
- 1 Gallon of oil can cause an eight-acre oil slick if spilled or dumped down a storm sewer!
- 97% of the worlds water is salty or otherwise undrinkable, 2% is stored in glaciers and the ice caps, the remaining 1% is left for humanity’s needs.
