Primo has a publicly available water quality report from 2017 (report attached). The report is detailed, but it lacks information on minerals of concern to brewers.

Total Dissolved Solids (TDS) Est, ppm 32
Electrical Conductivity, mmho/cm 0.05

All results below are ppm...

I used it for years. It is effectively a blank slate. You will have to add all your own brewing salts
