Nevertheless, our source water meets the EPA minimum drinking water standards before any purification is even done!! Read that again-that’s what we start with. We purify that water extensively and literally remove more than 99.5% of all incoming impurities. Since the purification process is designed to remove virtually all types of impurities, the quality of the source water has little bearing on the quality of the final product. Purified water may originate from either a spring, surface or groundwater source or directly from the tap. The resultant product, “purified” water, is of significantly higher purity than either spring water, tap water, or filtered water. While both types of water are subject to some sort of filtration (as is almost every spring water), purified water is cleansed and purified through additional purification processes, typically reverse osmosis, distillation, or deionization.
Many people believe the two terms to be synonymous, but this is not the case. Purified water is often confused with filtered water. The impurity load of dissolved solids in purified water cannot exceed 10 parts-per-million, and water that meets this threshold is inherently of a higher purity than spring water, tap water, or filtered water. To meet the legal definition of “purified water,” water impurities must be removed or reduced to extremely low levels.
Purified water is defined by the levels (or lack thereof) of any impurities found in the water. So, it’s very important to have additional purification technologies-besides only distillation-to make sure all the bad stuff is removed. Now, there’s one small problem with that process above. There are many volatile organic compounds found in water-and many of them have boiling points below that of pure water (like pesticides or herbicides and a whole lot of other volatile chemical compounds that have names far too difficult to pronounce, much less spell). The point is that when the water gets heated, the volatiles boil off first, then the pure water next. So, as the water (with its contaminants) is boiled, the pure water turns into steam and is captured and cooled and thus becomes distilled water. The junk left behind is all of the contaminants.

Basically, in the process of distillation, the pure H2O is boiled out of its contaminants. So, many of the contaminants found in water are inorganic minerals, metals etc. Those types of contaminants have very high melting points and even higher boiling points ( way higher than the boiling point of water at 212 degrees F). Before we get into the exact process differences between distilled and purified water, it’s important to understand what each type means. purified water comes down to the process the water went through to reach purification.
