To some extent, it depends where you live in regard to using tapwater for your plants, because different countries may use different chemicals to ensure it is potable, though generally, tapwater isn't a problem for potted plants. Different areas or regions within a country may naturally have either soft or hard water though, and that can be important where ericaceous plants are concerned; hard water means it contains lime. Using tapwater in a hard water area to water pot plants means, over time, you will notice a yellowish white crusty rim on the inside of the pot, and sometimes, as the soil dries out, perhaps a small amount of the same deposit dotted about on the top of the soil. This causes no harm to the plant in the pot, unless it's one that particularly dislikes lime (ericaceous plant).

A lot of warnings are often given about a 'build up salts' in the soil in the pot; this refers to what might be left behind by frequent fertilizer use. If you do not use fertilizer for your plants all the time, or only use it at minor to moderate levels, this won't be an issue either.

I live in the UK in a hard water area, and other than for any ericaceous pot plant, I have always used tap water with no problems apart from the scale build up on the inside of the rim of the pot after a couple of years. For ericaceous (acid loving/lime hating) plants, either clean rainwater or previously boiled and cooled water is better, because boiling takes out the lime (and leaves it all over the inside of my kettle...)
