I 100% recommend you to drink distilled water not Pur Aqua Spring bka bottled tap water. You can taste the difference as distilled water tastes pure and clean. With small traces of over 40 contaminates in tap water like fluoride, chlorine, feces, lead, arsenic, pesticides, fertilizers and cyanide to name a few, I would be cautious. In the US it is perfectly legal to have these chemicals in are tap water as long as it doesn't exceed the legal limit ppb (parts per billion), and that sounds/tastes shitty to me. Tap water comes from whatever source of water you live near like lakes, ponds, wells and springs. The water starts out as rain water (natural earth distilled water) but also keep in mind that water hits the ground and is now rolling around in dirt. And no we do not get are minerals from dirt but plants do! And yes bottle water like Pur Aqua Spring & Dasani gets there water from municipal water aka "tap water" which is sad that people pay $2 vs. using tap for $.00005 for the same volume. If you have any liver, kidney or urinary track disease it is recommend for you to drink distilled water because it helps removes impurities out your systems. But also you would want to have impurities out your body whether you're sick or not. Matter of fact if you’re going through dialysis the only water that is used in the machine is distilled water because tap or spring will just do the opposite and add impurities. It is all about the money & don't let the hundred billion dollar water company marketers tell you any different. Because it’s been known for centuries you can get free water from the ocean or gallons for the pennies using tap water by distilling your own water with your own home water distiller. Using filters to filter your water is expensive because you will always forever need to buy new ones and you will still have some contaminates like fluoride in your water. And yes, hexafluorosilicic acid (H2SiF6) aka fluoride is more toxic than lead and have a NFPA 704 Health (Blue) toxic level of 3. Matter of fact fluoride is the key ingredient used to make sarin gas( methylphosphonyl difluoride) , Prozac(Fluoxetine) and rat poison(Sodium fluoroacetate). Distilled water contains nothing but H2O. Save some money and get no poop (feces) traces in your water by distilling and drinking your own pure, clean cheap water.
