Seacoast Utility Authority: who runs Lake Park's water
Seacoast's own water page lists its service area as Palm Beach Gardens, Juno, Lake Park, North Palm Beach and unincorporated Palm Beach County. It is a not-for-profit governmental utility with no taxing powers, governed by a five-member board appointed by the local governments it serves. Lake Park holds one of those seats, with a 6% voting share according to Seacoast's 2025 Annual Water Quality Report.
| Question | Where to go |
|---|---|
| Water quality, the annual report | Seacoast Utility Authority laboratory, 561-627-2900 |
| Printed copy of the report, billing | Seacoast Customer Service, 561-627-2920 |
| Town services (sanitation, streets) | Town of Lake Park Public Works, 561-881-3345 |
The Town also posts Seacoast's water quality report on its own Community page, so residents can find it from either website.
Two aquifers, one membrane plant
Seacoast draws water from two groundwater sources: the shallow surficial aquifer, 75 to 200 feet deep, and the brackish Floridan aquifer, about 1,500 feet down. The 2025 report counts 38 surficial wells and 6 Floridan wells in five wellfields.
All of it goes to the Hood Road Membrane Water Plant, a 30.5 million-gallon-per-day facility made up of 26.0 MGD of nanofiltration, 3.5 MGD of low-pressure reverse osmosis and 1.0 MGD of pretreated surficial blend water. Seacoast describes the reverse osmosis as desalination for the brackish Floridan water and the nanofiltration as demineralization of the fresh surficial water.
That matters for your home. Water that has already passed through membranes at the plant tends to arrive lower in dissolved minerals than lime-softened water in other parts of South Florida, which is why a softener is often not the first thing a Lake Park home on city water needs. A tap test settles it.
Disinfection: chloramines
After treatment, Seacoast disinfects with chloramines, a combination of chlorine and ammonia. Its 2025 report lists chloramines at a highest locational running annual average of 3.7 parts per million, with results from 3.6 to 3.8, under the maximum of 4. The report explains that chloramines minimize disinfection byproduct formation and must be removed from water used in kidney dialysis and in fish tanks or aquariums.
Disinfection byproducts were low in 2025: total trihalomethanes at 7.9 ppb and haloacetic acids at 6.5 ppb, against limits of 80 and 60. The chloramine residual is the part most residents notice, as a faint pool-like taste or smell. See chloramine filters in Lake Park.
Fluoride, PFAS and lead: what the report says
- Fluoride: Seacoast's report says fluoridation is not practiced; fluoride occurs naturally at very low levels, under 0.2 ppm. See fluoride filters.
- PFAS: the report lists PFAS as not detected in samples from January and July 2024 under EPA's unregulated contaminant monitoring. See PFAS filters.
- Lead and copper: the 90th percentile tap results from June 2025 were 1.6 ppb for lead and 0.041 ppm for copper, with no sites over the action level. Lead, when present, usually comes from plumbing, so the age of your home's pipes matters more than the plant.
- Sodium: 35.5 ppm in the report's inorganic table.
Older pipes, the lagoon and irrigation
Lake Park is one of the older communities in northern Palm Beach County, and Seacoast's capital program includes neighborhood piping replacement projects in Lake Park, North Palm Beach, Juno Isle and Horseshoe Acres. The Town's site also documents a Seacoast project that replaced water and sewer lines along US 1 between Silver Beach Road and the Earman River in 2023. After main work, a short spell of cloudy or discolored water is common and usually clears by running the cold tap.
The town sits on the Lake Worth Lagoon, and some properties water their lawns from private irrigation wells. That untreated groundwater can leave orange stains or a sulfur smell outdoors, a separate issue from your tap. See orange stains and well and irrigation water.
What usually fits a Lake Park home
- Single-family home: a whole-home city water system for chloramine at every tap, often with under-sink alkaline RO for drinking water.
- Condo or apartment near the marina: under-sink RO, since you may not control the main line.
- Restaurant, office or other business: an ion-exchange softening plant only where a test shows hardness that threatens equipment. See water softeners in Lake Park.
- Private well: a well water system configured from the well's test.
