Water in the Human Body
Artesian water- water that is under natural pressure and thus flows to the earth’s surface on it own and is collected by a pump or well.
Mineral water- water that naturally contains a high level of minerals such as, calcium and sulfate.
Purified water- water that is treated by heat or a filter to remove certain minerals.
Spring water- water that comes from an underground aquifer and is collected from a natural spring or pumped up from the aquifer by a well.

Water Treatment
Activated Carbon Filter- A water treatment method in which organic materials are adsorbed from the water and attached to the outside of the Filter
Ion Exchange Unit- A water treatment method in which minerals and fluoride are removed but cannot remove materials if water has oxidized iron
Reserve Osmosis Unit- A water treatment method which can remove nitrates and sodium but can only remove some organic and inorganic contaminants, including heavy metals
Distillation Unite- A water treatment method which removes nitrates, sodium, and many other inorganic contaminants, can also kill bacteria
