I have read so much about StarSan losing effectiveness in hard water.  I have my municipality water report and the range of hardness is between 61-101 (as CaC03) ppm.  The NJ upper limit is 250.
iron ND-192 (upper limit 300)
aluminum ppb ND-172 (upper limit 200)
ph units 6.4-7.4 (upper limit 6.5-8.5)
silver ppb ND-9.7 (upper limit 100)
sodium ppb 22-27 (upper limit 50)
sulfate ppb 12-14 (upper limit 250)
zinc ppb ND-0.03 (upper limit 5)
Total dissolved solids 76-318 (upper limit 500) 

I have been using StarSan for years with no apparent ill effects.  Should I be concerned especially with making yeast starters?

While StarSan will still be effective in hard water, you won't be able to keep a solution that was made of that water without it becoming cloudy, slimey feeling, and coating your equipment if its left in the solution. The best option for creating a long-lasting StarSan solution is to use distilled water.

You won't need to be concerned with using that water for yeast starters, it's fine.

Not concerned about the water for starters, I was commenting on the effectiveness of SanStar while making starters.

StarSan does have an Achiles Heel in that it is not very effective against wild yeast and mold spores. That could be a problem for sanitization for starters.

Looking at the water profile above, would you consider this very hard water?

I buy a 5L bottle of distilled water and dose that up.  It keeps for ages like that, certainly longer than it lasts.

It's more than hard enough to create problems.
