All 32 towns
Palm Beach County water rankings
Every town we serve, ranked by what its utility’s own report says about how the water is treated — because treatment decides how much hardness reaches your tap, and only two utilities in the county publish the finished number. No vendor-blog figures, no guesses: every placement links to the official document behind it.
Tier 1
Full reverse osmosis systems
These utilities state in their own reports that all drinking water passes through reverse osmosis — the most thorough treatment offered in the county.
At the tap: Typically the least hardness left at the tap, though utilities re-add some minerals for pipe stability and none publishes the finished figure.
Tier 2
Membrane plants and blends (nanofiltration / RO)
Each of these utilities reports nanofiltration or reverse osmosis for some or all of its flow, often blended with conventionally treated water. Boca Raton and Tequesta are the county's only two utilities that publish a hardness figure — 65–80 mg/L and about 100–120 mg/L respectively, both from their own official pages.
At the tap: Generally softer than lime-softened systems, but the blend ratio decides what reaches you — and only a tap test settles it.

- Palm Beach Gardens, FLSeacoast Utility Authority

- Wellington, FLVillage of Wellington Public Utilities
Tier 3
Lime softening only
These utilities report conventional lime softening with no membrane stage — the standard treatment that removes some hardness but typically leaves more of it than membranes do.
At the tap: The systems where we most often measure meaningful hardness at the tap. None publishes its finished number.
Tier 4
Surface water with no softening step listed
The City of West Palm Beach — the county's only surface-water system — describes coagulation, sedimentation, filtration and UV in its report, with no softening stage listed.
At the tap: Surface water chemistry differs from the wellfield systems entirely; hardness is unpublished, so the tap test is the only number.
Tier 5
PBCWUD eastern system — treatment varies by plant
Palm Beach County Water Utilities' eastern system reports lime softening plus ion exchange, nanofiltration and reverse osmosis across different plants — which plant serves your street isn't something the report tells you.
At the tap: Your water may be membrane-treated or lime-softened depending on address. Genuinely unknowable without measuring.
Unranked
Private well country — nobody treats it unless you do
Large parts of these communities are on private wells. There is no utility, no report, and no treatment before your tap.
At the tap: Iron, sulfur odour and untreated hardness are common; a well build starts with the test and treats those before softening.
Unranked
Supplier not yet confirmed in a primary source
We only place a town when a utility's own document names it. These three sit on supplier boundaries or small village systems we haven't sourced yet — we'd rather leave them unranked than guess.
At the tap: The free test answers it either way.
The number that matters
Your tier is a starting point. Your tap is the answer.
Whatever tier your town sits in, the free test measures what actually arrives at your sink — and a correctly sized system takes it to under 1 grain per gallon at every tap, with an exact price before you decide.
