I'm on a Well, I got a test kit and there are very little minerals, no clorine, Alkalinity is only 80 ppm and the Hardness is 50 ppm.
I'm trying to make a Belgian, this is my second time, first one tasted great but absolutely no body in the beer.
One more thing, all my beers are good for limited times, where they go from Green to good tasting then turn bitter at some point, depending on beer, anywhere from 3-6 months.
As for softness it's not, if anything its "Hard", I add borax to my wash water to get better utilization of my soap and as example, soap in the shower does not foam at all, soap in the dish sink doesn't last long either. Dish washer, leaves spots unless you use a "Rinse" agent.
So if I were to adjust the Ph.. what to use? If it affects the minerals, there is plenty of room there.
As for taste of the water is tastes fine, no off flavors, very clean. Tastes like "Nothing".
