Hello everyone long time no see.  Well I completed my test on my last years cuttings where half were watered with city water and the other half well water.  I will take some pictures tomorrow weather permitting of two of the trees.  Same variety of fig all stored in the greenhouse in 3 gallon containers over the winter.  I maintained temps above 45 F and they received the same amount of direct sunlight each day.  They were watered for 2 minutes every three days.  Those cuttings that were watered with well water are 50% taller than the cuttings that received out city water.  The variety was a Hardy Chicago used a total of 6 cuttings in each control group.  I suspect the minerals and no chemicals are the two big factors.  I also, had no problems with mold on the cuttings that were rooted in ziplock bags and dampened the stock with well water.  I did have to scrub down 2 of the cuttings in one set that was watered with city water.  Just thought I would share this information with everyone.  Catching rainwater for rooting would be the best of both worlds.

The PH of the water may also contribute to the results as will things like chlorine that are present in most tap water.

Richard, Thank you for sharing your results! As you surmised and Figaro pointed out, the mineral/ionic composition of the 2 water sources are likely to be different. Associated with a potential pH difference that Figaro notes, your city water may be seriously alkaline. A terrific explanation of those 2 factors is in the attached pdf. A high pH with low alkalinity is not so bad. High pH with high alkalinity is another matter. If you want to test the alkalinity yourself, a good, accurate, easy to use & fairly cheap test kit is:

However, your water provider tests for all those things plus more. They know the pH, alkalinity, mineral composition, microbiological composition, etc. You can call them and request their test results. Whether they will tell you is another matter entirely. Some water service companies will and some will not. It is worth a phone call or two. If they do share, adding that info to this thread would be helpful I think.

Thank you again for reminding the forum that water quality makes a real difference!

You know I did not think about testing the Ph.  I don't know where my brain has been for the last 12 months.  LOL  I will call our water treatment plant today and see what they are willing to tell me.  Thanks to everyone that responded to my thread.  I will add additional information as it is collected.  Going to see if I can get a Ph tester locally and test my well.
