Currently, my tap water is at 18 grains, making a water softener a necessity for dishwashing.
There are a few homes, that have "whole home water softener systems", but it is a relatively insignificant number, and few find the water here to be a problem. Most homes dont event have water filters at the kitchen sink. My 89 yr old mother INSISTS on drinking the tap water for the mineral content and is convinced that she is healthier for it.
So...in short, i dont consider the water quality here an issue at all...in fact most would say the water here is good..even excellent.!! The water is sourced from artesian wells.
I've attached a link to the water quality report, from the city.....
