How Hard Is Your Water?

City of Stuart Water Treatment Facility — 2025 Report

ParameterWhat the Report Shows
Water SourceGroundwater from the Surficial Aquifer (23 production wells) plus one Floridan Aquifer well.
Treatment ProcessPFAS removal, lime softening, filtration, reverse osmosis, and disinfection (6.0 MGD plant capacity).
DisinfectantChloramines (2025 annual average 3.1 ppm; MRDL 4.0 ppm).
HardnessStuart's Consumer Confidence Report states treatment “reduces hardness” as part of the lime-softening process, but does not publish a specific mg/L or grains-per-gallon figure.
PFAS / Unregulated ContaminantsIn October 2023, EPA UCMR5 testing detected short-chain PFAS (currently unregulated, no EPA MCL) in two City wells; both were immediately taken offline and are no longer used to supply drinking water. The City approved a $300,000 pilot program (installing 2026) to evaluate advanced treatment media. The 2025 CCR's unregulated-contaminant results (sampled April 2025) list only 6:2 FTS, PFBA, and PFPeA in trace amounts — PFOA and PFOS were not listed, indicating non-detect in that round.

Stuart Homes & Hardness

Stuart's housing stock runs from historic downtown bungalows near the St. Lucie River to newer waterfront communities along the Intracoastal and canal-front neighborhoods built for boat access. Older homes closer to downtown often carry original galvanized or copper plumbing, which shows scale buildup faster than newer PEX systems.

What Homeowners Ask Us Most in Stuart

Because Stuart's supply blends surficial water with reverse-osmosis-treated Floridan water and the utility took two wells offline in 2023 over short-chain PFAS, homeowners here tend to ask us two things: whether their specific block was affected, and what the lime-softening process leaves behind in terms of hardness at the tap. Chloramine taste in showers is the most common day-to-day complaint.

Ion-exchange softening

The standard fix for calcium/magnesium hardness — resin swaps hardness minerals for sodium or potassium ions.

Salt-free conditioning

Crystallizes hardness minerals so they don't stick to pipes and fixtures, without adding sodium to your water.

Appliance & plumbing protection

Softening extends the working life of water heaters, dishwashers, and fixtures by preventing scale buildup.

Sized to your test, not a guess

Softener capacity is set from your actual hardness reading and household water usage.

Stuart Water Softener FAQ

Common Questions

Is Stuart's water hard enough to need a softener?

Stuart's Consumer Confidence Report states treatment “reduces hardness” as part of the lime-softening process, but does not publish a specific mg/L or grains-per-gallon figure. A free test at your address is the only way to get an exact number.

How is a softener different from a filter?

A softener specifically targets calcium and magnesium hardness. Filtration for chlorine, sediment, or other concerns is a separate (often complementary) system — see our softener vs. filter guide.

Will a softener fix scale that's already built up?

A softener prevents new scale from forming; existing buildup in pipes or on fixtures may need separate cleaning or, in severe cases, fixture replacement.

Do salt-based softeners affect my septic system or lawn?

Discharge volume from a properly sized, modern softener's regeneration cycle is generally minimal; if you have specific septic or irrigation concerns, ask your installer about a salt-free conditioning alternative.
