Deerfield Beach, FL

Deerfield Beach is the northernmost coastal city in Broward County, with the Hillsboro River and Boca Raton on its north side and Pompano Beach to the south. It was incorporated as the Town of Deerfield in 1925 and took the "Beach" in 1939; the original wooden pier was built in 1952. The 2020 Census counted 86,859 residents.

The water story here is unusual for South Florida. The City runs one treatment plant that uses three different processes on two aquifers and blends the results. A third of the city is on a different utility altogether. And the housing runs from 55-and-over condominiums to mobile home parks to houses on the Intracoastal, so the right system depends a lot on where you live and what kind of building it is.

Who Supplies Deerfield Beach Water: the City or Broward County

Two utilities share the city. The City of Deerfield Beach (EPA system FL4060254) serves about 62,000 people through 14,081 connections, according to EPA records. Broward County's water services map puts about one-third of the city's land area on Broward County Water and Wastewater Services instead.

On the County map, the dividing line runs close to SW 15th Street. North of it, and east of Powerline Road, homes are on City water: Century Village, The Lakes of Deer Creek, Broward Highlands, the Pioneer Park and City Hall area, The Cove, Little Harbor on the Hillsboro and Deerfield Beach Island. South of SW 15th Street, Park Haven, Crystal Lake and the blocks around Deerfield Beach High School are on County water, as is most of the area west of Powerline Road around Quiet Waters Park. The edges are irregular, so the name on your water bill is the reliable answer.

The County side is part of its District 2 system, treated at the 2A plant in Pompano Beach. That plant, built in 1975, uses lime softening and filtration on Biscayne Aquifer water, and one of its wellfields lies in and around Quiet Waters Park. The County has hired engineers to add nanofiltration at the plant, aiming for 2029, mainly to lower PFAS. Lighthouse Point, just south, drinks the same County water.

How the City Plant Treats Water: Lime, Nanofiltration and RO

The City's 2025 Water Quality Report describes one plant with three processes, fed by 14 active wells:

The three streams are blended, adjusted for pH and disinfected with chloramine (chlorine combined with ammonia) before entering more than 230 miles of pipe. The City stopped adding fluoride on July 1, 2025, when the state law banning it took effect.

Membrane water is low in hardness and organic matter, which helps explain the City's fairly low disinfection byproduct numbers. The lime-softened share still carries more of both, and the blend can shift with which processes are running, so your tap is the best guide to what reaches your home.

Deerfield Beach Water Quality Report: City Results for 2025

PFAS Test Results for the City and County Systems

The County's water tested higher. In the same EPA program, Broward County's 2A plant measured PFOS at 23.6 ppt in September 2024 and 28.4 ppt in March 2025, with PFOA at 7.9 and 11.5 ppt. The City plant's results were 12.7 and 5.2 ppt PFOS. Both are Biscayne Aquifer systems a few miles apart; the City's nanofiltration and RO likely account for part of the difference, since membranes of that kind reduce PFAS and lime softening does little to it.

Neither result is a violation now, because the limit isn't enforceable until the deadline and applies to a yearly average. If you want drinking and cooking water under 4 ppt on either system, an under-sink RO unit is the usual answer; our reverse osmosis systems use membranes of the same type as the City's RO plant, at kitchen scale. Whole-house carbon and softeners do little for PFAS.

Chloramine Taste and the County's Free-Chlorine Weeks

Both utilities disinfect with chloramine, so the faint pool smell is the same on either side of SW 15th Street most of the year. Catalytic carbon is the media that handles it; plain carbon in a pitcher or fridge filter does far less. A whole-house catalytic carbon tank also protects softener resin, which chloramine slowly breaks down.

County customers notice something extra. Broward County switches its District 2 system to free chlorine for about three weeks twice a year while it flushes hydrants (in fall 2026 it ran from September 28 to October 19), and the water smells stronger while that lasts. Older County testing also found chlorate, a disinfection byproduct, at 320 to 1,200 ppb at the 2A plant in 2014 and 2015, while the City plant had none above the reporting level. There is no federal limit for chlorate; RO reduces it.

Do You Need a Water Softener if the Plant Already Softens?

Often not on City water, but it depends on your reading. The City doesn't publish a finished hardness figure, and the numbers attached to Deerfield ZIP codes online usually belong to other utilities. What we know is that most of its water passes through nanofiltration or RO, which remove most hardness, and the rest is lime-softened. Boca Raton, which also blends nanofiltered and lime-softened water, reports finished hardness of about 4 to 5 grains per gallon. Deerfield's own figure may differ.

County water is lime-softened only, so it tends to read harder. Either way, a two-minute hardness reading is part of the free test. If you have spotting on glass and shower doors, scale in a tank water heater or a pool and outdoor shower that crust over, and the reading supports it, our water softener installation is sized to that reading. We use 10% crosslink resin, which holds up better on chloramine water, under a Fleck or Clack valve. If the reading is low, we'll tell you to skip it.

Century Village Condos, Mobile Homes and 1970s Plumbing

Deerfield Beach grew fastest from the 1950s through the 1980s. Of about 46,600 housing units, 17,926 were built in the 1970s and 10,821 in the 1980s, and the median building year is 1978 (Census ACS, 2020–2024). About 44% of units are in buildings with ten or more units, 27% are detached houses, and about 2,700 are mobile homes. Some 7,400 units are kept for seasonal use.

Century Village, the large 55-and-over condominium community off Hillsboro Boulevard, was built from the 1970s on and is on City water; the City even leaves copies of its water report at the Century Village main clubhouse. In a condo, a whole-house system needs access to your unit's main water line and the association's approval, as the Water Wizards FAQ explains. Most owners there start with an under-sink RO or carbon system, which stays inside the kitchen cabinet.

Homes built before 1986 may have lead solder on copper joints. The City found no lead service lines, but one home in its 2023 sampling exceeded the lead action level, which is the pattern you'd expect when the source is inside the house. For homes and buildings older than 1986 we send a first-draw sample to a certified lab at no charge. In mobile homes, ask us to look at the water heater and supply lines when we test, since space for a softener or carbon tank is tighter.
