I have access to a spring. I have tested the water. There is no ammonia and the GH and KH and pH is the same as what I use from the tap water.
Would it be ok to use the spring water for water changes?

Should be. The spring water doesn't have an odd color to it, does it? If it's bluish-green, you've got copper in the ground, and that would be really bad for your fish.
Other than that, I'm guessing that this spring and your municipal water come from the same source, so if there are no minerals that the city is having to filter out, there shouldn't be an issue.

The water is very clear. People drive for miles to get this water.
Thank you for your help!

There still is a possibility of small amounts of minerals, but these are usually noticed by people. If the water is that sought-after, it's probably a really healthy source.
