Reading the clues
| What you see | Likely meaning |
|---|---|
| Light spots that wipe off | Dissolved solids from drying |
| Crust on aerators that returns fast | Higher hardness than expected; test it |
| Orange marks near sprinklers | Irrigation well iron |
| Salty haze on outdoor glass | Sea spray, not tap water |
What is in the water
The 2025 report lists, from January 2025 sampling, total dissolved solids of 243 ppm, chloride of 39.5 ppm and sulfate of 36.6 ppm, all below secondary standards. Hardness, the calcium and magnesium a softener removes, is only part of that, and the plant reduces it by lime softening. The rest leaves marks whether or not you soften.
That is why homes on the island can see light spotting on glass even though the water is softened at the plant. The spotting is real, but it is not the kind of heavy scale a softener is designed to prevent.
Stemware, mirrors and stone
- Hand-wash and dry crystal and stemware right away, or use RO water for a final rinse.
- Squeegee shower glass after each use.
- Avoid acidic cleaners on marble and limestone; use products made for stone.
- Use rinse aid in dishwashers.
Softener or conditioner
- Ion-exchange softener: removes calcium and magnesium; uses salt.
- Salt-free conditioner: aims to reduce scale formation without removing minerals; spots remain.
Neither removes the other dissolved solids. See salt-free conditioner vs. softener.
Outdoors
Windows and cars near the ocean collect salt spray that dries into a white haze. Spots where sprinklers hit come from the irrigation water. Neither is your indoor tap water. Orange marks have their own page: iron stains in Palm Beach.
Cars parked near the ocean collect the same haze; washing in shade and drying right away avoids adding tap-water spots on top of it. A freshwater rinse soon after a windy day, then drying, removes salt haze better than any household water treatment.
When a softener makes sense
A measured high reading, a commercial kitchen, or a well. See water softeners in Palm Beach.
