Water Treatment in Palm Beach Gardens

Reverse Osmosis in Palm Beach Gardens: What Seacoast's 2025 Water Report Shows

Seacoast's 2025 Annual Water Quality Report (issued May 2026) shows the water met all federal and state standards. Seacoast also placed second in the Region VI water-tasting competition of the Florida Section of the American Water Works Association. Here is what the report lists for the eastern system that serves most Gardens homes, and what each figure means for a drinking-water system:

• Chloramine: 3.7 ppm average, with every monthly result between 3.6 and 3.8 ppm, against a 4.0 ppm maximum. Some neighboring utilities swing up and down; Seacoast holds steady near the top of the allowed range. That steady residual is the taste and smell you notice in ice and coffee, and it is the main job for any filter in the Gardens.
• PFAS: not detected in either the January 2024 or the July 2024 sampling. Seacoast's PFAS statement says no further PFAS monitoring is required until 2027, and that its nanofiltration and reverse osmosis processes remove these compounds. That is a very different starting point from Boynton Beach, where 2025 PFOS results reached 31 parts per trillion.
• Disinfection by-products: total trihalomethanes (TTHM) averaged 7.9 ppb (range 4.6 to 10.0) and haloacetic acids (HAA5) 6.5 ppb (range 3.4 to 11.8). Both are far below the 80 and 60 ppb limits and among the lowest figures we have seen in a Palm Beach County report.
• Lead and copper: the 90th-percentile lead result in June 2025 was 1.6 ppb. Two of the sampled homes came in above the 15 ppb action level. Seacoast states it has no lead service lines, so lead at a Gardens tap comes from the home's own plumbing, solder or fixtures. Copper's 90th percentile was 0.041 ppm.
• Sodium and fluoride: sodium 35.5 ppm and fluoride 0.13 ppm (both from 2023 sampling). Seacoast does not add fluoride, so RO removing fluoride is not a real trade-off here.

Put together, an under-sink reverse osmosis system in Palm Beach Gardens is mostly about taste, chloramine and the home's own plumbing, not about PFAS coming from the plant. The carbon stages in front of the membrane remove chloramine. The membrane removes lead picked up from older fixtures and solder, plus most of the remaining sodium and dissolved solids. If lead is your reason for calling, we install units whose NSF/ANSI 58 certification lists lead reduction. Every install includes a dedicated faucet and, if you want it, a line to the refrigerator ice maker. The full process is on our reverse osmosis installation page, and if you are still choosing between RO and other options, start with our drinking water systems guide.

Avenir and the Western Communities: Different Water, Different System

The 2025 West-Consecutive report shows why we never assume one set of numbers for the whole city. Water bought from Palm Beach County Water Utilities and delivered to Avenir, Ancient Tree, Carleton Oaks, Osprey Isles and the Park of Commerce tested like this:

• Disinfection by-products: TTHM 33.6 ppb (range 14.0 to 47.4) and HAA5 29.7 ppb (range 23.8 to 35.9). That is roughly four times the eastern system's levels, though still under the 80 and 60 ppb limits.
• Chlorine/chloramine: 3.0 ppm average, monthly range 2.4 to 3.5 ppm.
• Nitrate: 0.37 ppm at the East entry and 0.34 ppm at the Mecca entry, against a 10 ppm limit.
• Lead: 90th percentile 0.65 ppb in both the May and October 2025 rounds, with no sites over the action level.

Seacoast's PFAS statement for these customers passes along the county's position: three of Palm Beach County Water Utilities' plants already meet the EPA's PFAS limits, which take effect in 2031, and work is underway on the other two. Seacoast's report does not list a PFAS result for the western system, so we do not quote one.

For a new Avenir home, our usual recommendation is a whole-house catalytic carbon system sized for chloramine and by-products, plus an under-sink RO at the kitchen. That combination handles both the TTHM/HAA5 load and the PFAS question while the county's plant upgrades are still in progress. Whether a softener is worth adding depends on the hardness we measure at your tap, not on a countywide chart.

Do Palm Beach Gardens Homes Need a Water Softener?

On Seacoast's eastern system, many homes do not need a large softener, and we would rather say so than sell one. Nanofiltration removes much of the hardness at the Hood Road plant. Seacoast does not publish a hardness figure in its water quality report, so we measure yours with a water test before recommending anything.

A softener still earns its place in some Gardens homes:

1. Tankless water heaters and frameless shower glass. Even moderate hardness, combined with evaporation, leaves spotting on glass and slowly scales heat exchangers. Many tankless manufacturers set hardness limits in their warranty terms, so we check your unit's limit against your measured hardness.
2. Homes in the western communities. County-supplied water is treated differently from Seacoast's membrane water, so the measured hardness there is the deciding number.
3. Existing softeners set for the wrong water. Many Gardens homes have a softener installed by a previous owner and programmed for 'very hard' water. On membrane-softened water that wastes salt and regenerations. Re-setting it to your measured hardness is a service call, not a new system. See our water softener installation, repair and maintenance page.

When a softener is the right call here, Seacoast's lower starting hardness means a smaller metered unit, less salt and fewer regenerations than a Loxahatchee or Acreage home would need.

Hydrant Flushing, Boil Water Notices and Your Filters

Seacoast flushes hydrants neighborhood by neighborhood and announces it on its website. Its current notice covers nighttime flushing in PGA National from Friday, October 10 through Friday, October 17, between 9 PM and 3 AM, in Villas of Burwick, Golf Villas, Eagleton Cove, Augusta Pointe, Diamond Head, Monterey Point and Canterbury. Seacoast says the water may look cloudy afterward from tiny air bubbles (white) or suspended iron (yellow), and that it clears if you run the faucet for a few minutes.

If you own water treatment equipment, three things are worth knowing:

1. Run a tap that bypasses the filters first. Clear the discolored water through an outdoor hose bib or an unfiltered tap before you use the kitchen RO or run laundry. Suspended iron is exactly what clogs a sediment pre-filter early.
2. Watch pressure for a few weeks after flushing. If whole-house pressure or RO output drops after a flush in your area, the sediment cartridge is the first thing we check, and it is a quick replacement.
3. Filters do not replace a boil water notice. Seacoast posts precautionary boil water notices by street address after main repairs. One in late September 2026 covered 10605 to 10720 Avenue of PGA. Carbon filters and softeners do not disinfect water, so follow the notice until Seacoast rescinds it, whatever equipment you have.

Seacoast is also partway through a three-year, $138.5 million capital program. It includes neighborhood pipe replacement in Lake Park, North Palm Beach, Juno Isle and Horseshoe Acres, roadway corridor piping work and hydrant and valve replacement. Construction nearby is a common reason for a short stretch of sediment or air in the lines. A sediment pre-filter ahead of your carbon tank is the inexpensive protection.

How We Size Systems for Palm Beach Gardens Homes and Businesses

• Gated golf communities (PGA National, BallenIsles, Mirasol, Old Palm, Frenchman's Reserve): large homes with 4 or more bathrooms, pool cabanas and often tankless or multiple water heaters. We size whole-house carbon for peak flow, so pressure holds when irrigation, showers and the dishwasher run at once. Equipment goes in the garage or an equipment room, and we coordinate with the HOA when a system has exterior parts.
• Condos and townhomes near PGA Boulevard and the Gardens Mall: usually no room for a whole-house tank. An under-sink RO plus a chloramine shower filter stays inside your unit, and most associations do not require approval for it.
• Newer construction in Avenir and the western communities: builder-plumbed homes on county-supplied water. We test before quoting because hardness and disinfection by-products there differ from the eastern system.
• Offices, medical practices and restaurants along PGA Boulevard and Northlake Boulevard: carbon ahead of ice machines, coffee equipment and beverage lines, and carbon or RO ahead of any equipment that needs chloramine-free water. Seacoast's report states that chloramine must be removed from water used for kidney dialysis and from water for fish tanks and aquariums. See our commercial RO maintenance and commercial carbon filter media service pages.

Neighbors to the east share the same Seacoast water and are covered on our North Palm Beach page. To the north, the Town of Jupiter and Jupiter Farms are on different supplies (see our Jupiter page). Further south, the City of West Palm Beach runs its own surface-water system, covered on our West Palm Beach page. To start with the numbers for your own home, book a free water test.
