I used tap water and just purified it with the proper product before inserting plants and eventually fish.
You need to clear the chemicals from tap water (chlorine etc)

I use tap water, I treat it of course.

I was advised that the most important thing with tank water is that the quality is consistent.
Tap water quality is consistent.

Spring water would be perfect - if you are able to gather it straight off the glacier run-off, right at the source. Any farther down the line and there is no telling what could be in it. For all you know the stream could have passed through a mine and could contain harmful acids, or viruses, or any of a hundred other things.

As far as tap water goes it can fluctuate from one area to another. Some examples of chemicals found in tap water include: chlorine, chloramines, phosphate, silicates, iron, copper, flouride, nitrates, chloroform, barium, and arsenic. In all there are around 260 different chemicals that can be found in the drinking water across the nation.

Here is an excerpt that I found while researching some of this information.

"The top 10 states, listed in order of the most contaminants in their drinking water, were: California, Wisconsin, Arizona, Florida, North Carolina, Texas, New York, Nevada, Pennsylvania and Illinois, according to EWG, which listed the biggest sources as agriculture, industry and urban and sprawl developments."
