Water Quality in Port St. Lucie, Florida

The Port St. Lucie water quality report is the city Utility Systems Department's annual Consumer Confidence Report, and the current edition, the 2025 Water Quality Report, was published on June 1, 2026 (2025 Water Quality Report page).

The city page says the report is published in compliance with federal legislation and, unless otherwise noted, covers sampling and testing conducted between Jan. 1, 2025, and Dec. 31, 2025. It describes the document as an explanation of where the water comes from, how it is protected and how residents can help conserve it. A copy can be requested by email at utility@cityofpsl.com, and the same page links every past edition from 2013 through 2024 for anyone comparing years (2025 Water Quality Report page).

Inside the report, the Utility Systems Department lists its office at 1001 SE Prineville St., Port St. Lucie, FL 34983, and its information line, 772-873-6400 (2025 Water Quality Report). The headline statement is that the drinking water provided by the department continues to meet all federal and state requirements, and every violation column in the result tables reads N (2025 report). One practical note: some rows are not 2025 samples. The lead and copper results date from sampling in June to August 2023, and several plant rows carry a 3/23 sampling date, so the report year and the test date are not always the same.

Port St. Lucie tap water comes from two independent aquifers, the shallow East Coast Surficial aquifer and the much deeper Floridan aquifer, treated and then blended (2025 Water Quality Report).

For Port St. Lucie, raw water from the East Coast Surficial aquifer, about 100 feet deep, goes to an 8 million gallon per day lime softening facility, where the process combines pH adjustment with lime, coagulation with a polymer, multi-media filtration and disinfection with chloramines. Water from the Floridan aquifer, about 1,350 feet down, is treated by two reverse osmosis facilities, one rated at 11.15 million gallons per day and the other at 22.5 million gallons per day. Both finished waters are blended, pH adjusted and disinfected before delivery (2025 report). The report's source trace map names the Prineville and James E. Anderson water treatment plants and the Midport, Southport, Westport and Rangeline storage and pump stations.

In 2025 the Florida Department of Environmental Protection ran a Source Water Assessment on the Port St. Lucie system and identified 13 potential sources of contamination near the wells, all at a low to moderate susceptibility level, with full results on the DEP Source Water Assessment and Protection Program website (2025 report). The report stresses that these are potential sources only. It also counts more than 100,000 connections to the distribution system and asks owners to avoid cross connections, such as an unprotected garden hose lying in a puddle or an unprotected lawn sprinkler system.

Not every address with a Port St. Lucie mailing address drinks city water. St. Lucie West has its own provider, the St. Lucie West Services District, whose site carries its own utility accounts and billing and water quality links (St. Lucie West Services District), so a St. Lucie West household should read that district's report rather than the city's.

The 2025 Port St. Lucie report shows every regulated result below its federal limit, with no violation recorded for any contaminant, disinfectant or by-product in the tables (2025 Water Quality Report).

All figures above are copied from the result tables of the 2025 Water Quality Report. Barium also appears at both plants, 0.0027 ppm at Prineville and 0.0032 ppm at James E. Anderson, against an MCL of 2. For the two disinfection by-products, the level detected is the highest locational running annual average of the year, which the report defines as the average of a monitoring location's results over the previous four calendar quarters.

The definitions page of the Port St. Lucie report explains the abbreviations: MCL is the highest level of a contaminant allowed in drinking water, an action level is the concentration that triggers treatment or other requirements, ND means not detected, and ppm and ppb stand for parts per million and parts per billion (2025 report).

The City of Port St. Lucie reports that zero lead service lines were identified within its utility service area, so no service line replacement is needed (EPA Lead and Copper Rule page).

The city completed the service line identification required by the EPA Lead and Copper Rule Revisions and Lead and Copper Rule Improvements, checking whether any homes had lead or galvanized service lines. The page notes that a service line is the pipe connecting the water main to the building inlet, that these lines are not part of the city utility system and that the builder installed them when each house was built (EPA Lead and Copper Rule page). Questions go to utility@cityofpsl.com or 772-873-6400, and the page links a frequently asked questions PDF.

Tap sampling is a separate measure. In the 2025 Port St. Lucie report, the lead and copper results come from household taps sampled in June to August 2023: the copper 90th percentile was 0.11 ppm against an action level of 1.3 with no sites over it, and the lead 90th percentile was 4.6 ppb against an action level of 15, with 1 site exceeding the action level and no action level violation for the system (2025 Water Quality Report). The report says the Utility Systems Department cannot control the variety of materials used in home plumbing, advises flushing pipes for several minutes by running the tap before drinking, and tells anyone who wishes to have the water tested to contact the department at 772-873-6400.

Yes, the 2025 report lists PFOS, PFOA, PFHxS and PFBS as detected at the Prineville plant, while every PFAS row for the city's other plant reads ND (2025 Water Quality Report).

The figures are in parts per trillion and come from the UCMR 5 tables in the 2025 Water Quality Report, which label the right-hand column as a proposed MCL rather than an enforceable limit and list discharge from industrial chemical factories as the likely source for each compound. The UCMR 5 tables, titled Unregulated Contaminants Monitoring Rule, carry no violation column. The report names the Prineville site as home to both the reverse osmosis and the lime softening water treatment plants.

A rotten egg smell in Port St. Lucie tap water usually comes from sulfate-reducing bacteria in stagnant water, and the city says the problem often sits in the water heater rather than the supply (Frequently Asked Water Quality Questions).

According to the Port St. Lucie Utility Systems FAQ, the bacteria take hold when flow is stagnant and the chlorine has dissipated, converting sulfate into hydrogen sulfide, a gas that smells like rotten eggs. The city's test takes two glasses: run the cold water for 1 to 2 minutes and smell a glass of it, which may carry a slight chlorine odor, then smell a glass of hot water; if only the hot water smells, the water heater is the source, and flushing it per the manufacturer's manual is the simplest fix (FAQ page).

The same Port St. Lucie FAQ covers other common complaints. After a long trip, the city suggests running the bathtub for about 5 minutes to push stagnant water out of the pipes, longer in a large home. A pink ring in a toilet is the airborne bacterium Serratia marcescens, not the water, and black slime on faucets and shower heads is a naturally occurring mold that the city says is not present in its drinking water; pouring 1 cup of bleach into the toilet tank and flushing controls it (FAQ page).

Port St. Lucie is adding raw water wells now and plans a new reverse osmosis plant, the Discovery Water Treatment Facility, which the 2025 report says is anticipated to be operational in late 2029 at 10 million gallons per day (2025 Water Quality Report).

The Port St. Lucie report says Discovery could produce 30 million gallons per day with future expansions, and that six new Floridan wells, two deep injection wells, one monitoring well and about 16,000 feet of raw water main will be built alongside it. Four new Floridan wells for the James E. Anderson plant are in the design and construction phase, and the Prineville plants are getting a new deep injection well plus a generator building (2025 report).

On the ground, Port St. Lucie has a contract for nine raw water supply wells and about 3.5 miles of raw water main, three wells in the northwest of the city and six in the southwest; construction began in November 2025, is expected to continue through 2029, and the city says water service will not be affected (Well construction projects page). A separate Class I injection well system for the brackish concentrate left by reverse osmosis began construction in September 2026 (Well construction projects page).

Lawn water is a separate supply in some neighborhoods. The Glades and Westport wastewater treatment plants send more than 1 million gallons of reclaimed water a day to golf courses and communities such as Tesoro Club and the Veranda Gardens neighborhoods, and the city says it is for irrigation only and must never be connected to drinking water or sewer lines (Reclaimed Water page).
