Judy,Its important to know just what impurities are important to a particular process. For instance plain tap water, providing its clean, is quite suitable for most conventional photographic processes. Hard water can often be at least partially softened just by boiling it for several minutes. This will drive out some types of dissolved gases (but not all) and will deposit some hardness as a crust on the vessel. By using an activated charcoal filter (like a Brita filter) in addition to boiling its possible to get reasonably pure water at low cost.
There was a story a few months ago about a popular brand of bottled fancy water that turned out to be just plain tap water. I think the company had to change their labels.
Note that genuinely chemically pure water tastes pretty flat, or in the words of Pogo Possum, 'This water has too much of a tasteless taste."
