Pure Water
Pure water means different things to different people, depending on whether you are a homeowner, chemist or farmer. In its simplest form water is H20 -- two parts hydrogen, one part oxygen. That's it. Free from adulterants and impurities like particulate, minerals, salts, bacteria or any other contaminants. Unfortunately, nowadays it is virtually impossible to find "pure" water in its natural state anywhere in the world.
Besides the naturally occurring inorganic materials found in most ground and river waters, there can be countless chemicals, bacteria, viruses, and radioactive substances. These pollutants may come from agricultural runoff and include pesticides, herbicides and fungicides and fertilizers such as nitrates, sulfates and chlorides. Industrial and power plant waste dump and emit waste into the water and our atmosphere. Exhaust fumes from cars and buses provide hydrocarbons and other pollutants, which find their way into our lakes, rivers, streams and reservoirs.
The majority of people get their water from municipal water supplies through their household tap. The source of water is from river, lakes and reservoirs. While the tap water goes through a cleaning process at the local water treatment plant, many potentially harmful contaminants and water borne diseases are present in the water delivered to the home.
For most of us to have access to pure water, the water needs to be treated with a secondary process. There are several technologies available, all of varying capabilities: filtration, reverse-osmosis, ultra-violet and distillation. Of these four technologies, distillation removes the broadest range of contaminants, is the closest to the definition of pure water and is the most effective of the technologies for removing organic, inorganic and biological contaminants.
Pure water is H20 with all the contaminants removed.
