The bottles being discarded by the consumers are damaging the environment. 89 billion liters of water is being bottled each year, besides the number of bottles required to bottle this volume of water, the energy to transport this world wide is a problem in its self. 8. Spring water comes from springs and purified water is “better filtered tap water” 9. Tap water is considered to have the best purity and is the best cost efficient due to the EPA. They have strict standards and only regulate tap water not bottled water means that it is more pure. I would agree with this article. 10.

Seawater is forced through a semi-permeable membrane, which removes all of the dissolved solids and produces fresh, potable water on the other side. The High Pressure Pump supplies the required force to drive the feed water through the semi-permeable Reverse Osmosis (R.O.) Membrane. The fresh water produced flows out of the Reverse Osmosis Membrane where it is up to 99.2% free of salts, minerals, and other ions. It then passes into the Product Flow Meter where the amount of potable water produced per minute is registered. 14. I think that making a desalination plant would be a good idea since Australia does need as much water as possible due to its harsh sun. but on the other hand, it may be worse, with all the fossil fuels being used and all the gases coming out, it may just cause the sun to be worse.
