g chance of contamination. To really know what you are drinking, you have to take into consideration the TDS level of the water and this can be determined by the geology of the local area where the water comes from. TDS is a measure of the combined content of all inorganic substances contained in a liquid (in micro-granular suspended form).
Harvesting and collecting rainwater, especially in remote areas of the world like Tasmania is a very good way of producing pure water. In these remote locations of the world, air pollution is almost non-existent so that means that the water that comes down during a rainstorm is some of the purest. Even still, the collection and harvesting process must be done properly in order for the water to be drinkable. For the most part, rainwater has extremely low mineral content and a lot of times is nitrate free.
To understand why distilled water may not be the best choice, you have to understand how the filtration process works in this instance. Contaminated water is boiled to remove harsh toxins, micro-organisms and bacteria. This process is supposed to create pure water steam and that steam is captured and cooled leaving the bacteria behind. Unfortunately, organic compounds and some metals that is found in the pre-boiled regular water have a very high boiling point. This very high boiling point exceeds the boiling point for water so technically, distilled water is not 100% pure either.
A tapped artesian aquifer, which is usually made from sandstone, will force the water up to the top of the well without the use of a man-made machine. The pressure built up in an aquifer will bring the water to the surface with force and can even sometimes create a permanent fountain. Artesian water matches spring water’s range of characteristics as you can tell, but the possibility of contamination is low due to no toxins from a man-made machine.
