The pool taste and smell · chloramine, 1.8 ppmCatalytic carbon takes it out
No crunchy scale or stiff laundry · genuinely soft water, 0.1 gpgNo softener needed, ever
That pool taste in your coffee and ice is chloramine, the disinfectant this system uses. The water tests soft, so a softener is not part of what we would put in.
What we'd do at your house
The Complete Home package: whole-home catalytic carbon for the chloramine at every tap, plus reverse osmosis at the kitchen sink for drinking water, ice, and spot-free glasses at that tap. Mandeville core city tests soft, so no softener goes in.

What this means at your house
Your water arrives with chloramine in it, at 1.8 parts per million. That is the disinfectant Mandeville Water Supply uses, and it is what people taste in coffee, in ice, and in the first glass of the day. Chloramine does not gas off in a pitcher the way chlorine does, so catalytic carbon is the piece that takes it out, at every tap in the house.
The hardness here is 1.8 milligrams per liter, about 0.1 grains. That is soft water by any measure, so a softener would have almost nothing to work on and we leave it out of the plan.
The water here is groundwater, pumped from 5 wells (Beau Rivage, North Lake Shopping Center, Well #6/Atalin St, Well #7/Hwy 190, Well/Mandeville High Blvd).
