Jacksonville's tap water comes from the Floridan Aquifer and is treated by JEA, which tests for PFAS, lead, and other contaminants under EPA rules. In EPA's UCMR5 testing, JEA's main grid showed no PFOA or PFOS above the reporting limit, but two short-chain PFAS were detected at low levels. A certified carbon block filter handles lead and long-chain PFAS; reverse osmosis is the more reliable choice for short-chain PFAS.
JEA (originally the Jacksonville Electric Authority; the utility's official name has been JEA since 1998) serves about 407,000 water customers, pumping from roughly 139 wells into the Floridan Aquifer, one of the most productive aquifers in the U.S. The aquifer provides naturally filtered water, but it's not immune to modern contamination. Low levels of PFAS, lead risk from older home plumbing, and salty, high-chloride water in parts of the system all show up in JEA's data.
In the EPA's UCMR5 testing program, JEA's Major Grid had no PFOA or PFOS detections at or above the 4 parts per trillion reporting limit. Two short-chain PFAS were detected: PFPeA (up to 6.8 ppt) and PFPeS (up to 5.2 ppt), and neither has a federal limit. The EPA maximum contaminant levels (MCLs) finalized in April 2024 set limits of 4 ppt for PFOA and 4 ppt for PFOS individually, with compliance due in 2029.
But the EPA limits only cover six PFAS compounds, and in May 2026 EPA proposed dropping four of them. The PFAS family includes thousands of chemicals, and UCMR5 screened for 29. If you want near-zero PFAS in your drinking water, filtration is the move.
Jacksonville's water system faces pressures that cities like Dallas or Louisville don't deal with. Not just PFAS.
Salty water. Deeper parts of the Floridan Aquifer hold brackish water, and heavy pumping can draw it toward wells. JEA's latest water quality report shows Major Grid chloride ranging from about 9 to 319 mg/L (2023 sampling), with the top of that range above the EPA's 250 mg/L secondary (taste) standard. Chloride affects taste, not safety, but reverse osmosis is the filter type that removes it.
Hurricane disruptions. During Hurricane Irma in 2017, JEA issued a precautionary boil-water notice for about 1,300 customers served by its Ponce de Leon plant after water pressure dropped. A filter won't help if the pipes break, but it does reduce the contaminant load during recovery periods when treatment systems are operating at reduced capacity.
Old infrastructure. JEA maintains about 5,244 miles of water distribution lines. Lead pipes and lead solder were banned in 1986, but pre-1986 homes may still have lead solder or brass fixtures that leach lead into tap water. In JEA's July 2023 Lead and Copper Rule sampling, the Major Grid's 90th percentile lead level was 1.5 ppb, with none of 86 homes over the EPA action level of 15 ppb. Low, but not zero. The CDC states that no level of lead exposure is safe for children under six.
The EPA finalized the first-ever PFAS drinking water standards in April 2024. Water systems must comply by April 2029. Here's what JEA has to do:
JEA's current PFAS levels are below the new MCLs, so no immediate treatment upgrades are required. But monitoring will intensify. UCMR5 was a one-time snapshot; the new rule requires initial monitoring at every entry point to the distribution system, then ongoing monitoring at a frequency based on the results. In May 2026, EPA also proposed letting some systems request until 2031 for PFOA and PFOS.
JEA looks likely to stay in compliance without major infrastructure changes, since PFOA and PFOS weren't detected above the reporting limit. Its treatment is aeration (to strip the sulfur smell), ozone at two plants, and chlorine disinfection; it doesn't use activated carbon, so it isn't removing PFAS. If you're in an older neighborhood with cast-iron or lead service lines, or if you're sensitive to even trace PFAS (pregnant, immunocompromised, young kids), a home filter is the safest bet.
We recommend carbon block or reverse osmosis filters for Jacksonville tap water. Certified carbon block removes chlorine, VOCs, lead, and long-chain PFAS like PFOA and PFOS. Reverse osmosis is more reliable for short-chain PFAS, the kind detected in JEA's testing, and also removes dissolved salts like chloride.
Here's what each maker's certifications and published test data cover:
| Filter | Type | PFAS Removal | Lead Removal | Format | Price | Amazon Link | |--------|------|--------------|--------------|-----------|-------|-------------| | APEC ROES-50 | Reverse Osmosis (WQA-certified to NSF 58) | Brand says reduces PFOA/PFOS | Brand says reduces lead | Under-sink, 50 GPD | ~$160-230 | APEC ROES-50 | | Aquasana AQ-5200 | Carbon Block | Certified for PFOA/PFOS (NSF 53) | Certified (NSF 53) | Under-sink | ~$125-250 | Aquasana AQ-5200 | | Big Berkey | Gravity Filter | Brand-reported lab tests; not certified | Brand-reported lab tests; not certified | Countertop | ~$350 | Big Berkey | | Brita Elite | Pitcher | No current PFAS certification | Certified (NSF 53) | Fill/wait | ~$35 | Brita Elite | | ZeroWater ZP-010 | Pitcher | Certified for PFOA/PFOS (NSF 53) | Certified (NSF 53) | Fill/wait | ~$45 | ZeroWater ZP-010 |
Our take: The APEC ROES-50 is overkill for most Jacksonville households, but it's the safest choice if you want the short-chain PFAS and the salty taste gone. The Aquasana AQ-5200 handles JEA's water profile well: it's certified for PFOA/PFOS, lead, and chlorine reduction without stripping beneficial minerals. For renters or anyone who doesn't want to install under-sink hardware, the Big Berkey is portable and high-capacity.
The Brita Elite and ZeroWater are budget options. Both are certified for lead. ZeroWater is also certified for PFOA and PFOS; earlier Brita Elite data sheets listed that certification too, but Brita's current one does not. And a 2020 Duke and NC State study of home filters found pitcher-style carbon filters removed short-chain PFAS less consistently than reverse osmosis. ZeroWater's ion-exchange filter also wears out faster in mineral-heavy water, and JEA's water is very hard in most ZIP codes (roughly 194-372 mg/L as CaCO₃, per JEA), so expect shorter filter life.

JEA publishes annual water quality reports, but they show system-wide averages, not your specific tap. We pulled EPA UCMR5 data for Jacksonville ZIP codes and mapped PFAS by ZIP code. Plug in your ZIP to see which PFAS compounds were detected at your local water system's entry point.
Keep in mind: UCMR5 sampling ran from 2023 to 2025 and is a snapshot. Levels fluctuate seasonally and by location within the distribution system. If your home was built before 1986, lead contamination from your own pipes is probably a bigger risk than PFAS from the source water.
Whole-house filters treat water at the entry point before it reaches any tap. They're useful for removing chlorine (which damages appliances and dries out skin), sediment, and some VOCs. But most whole-house carbon filters don't remove PFAS or lead effectively – they're designed for high flow rates, which means short contact time with the carbon media.
If you want whole-house PFAS removal, you need a system designed and sized for PFAS (large carbon or ion-exchange vessels with enough contact time), ideally with certified or independently tested PFAS claims. These systems typically cost thousands of dollars installed, and Duke and NC State researchers found some whole-house carbon systems performed inconsistently for PFAS. For most people, a point-of-use filter (under-sink or countertop) makes more sense. You only need ultra-filtered water for drinking and cooking – showers and laundry don't require it.
We're not sure how salty groundwater affects PFAS movement in aquifers. A 2022 USGS study of wells in five eastern U.S. aquifer systems (McMahon et al., Environmental Science & Technology) found PFAS in 60% of sampled public-supply wells, and chloride tended to be higher where PFAS were detected, but the two co-occurred rather than one causing the other. The data is thin, and JEA hasn't released any research on this interaction in the Floridan Aquifer.
Another uncertainty: JEA's treatment (aeration, ozone at two plants, chlorine) isn't designed to remove PFAS, so the low levels in treated water largely reflect what's in the aquifer. UCMR5 sampled treated water, which meets the standards today. If aquifer levels rise, JEA would need to add treatment such as GAC or ion exchange.
And one more thing: hurricanes. Storms can cause pressure drops and boil-water notices, as Irma did for some JEA customers in 2017. There's no published data on whether flooding moves PFAS from contaminated soil into the deep Floridan Aquifer that JEA pumps from, so the size of that risk is unknown.

What contaminants does JEA test for in Jacksonville's water? JEA tests for the contaminants EPA and Florida regulate, including lead, copper, arsenic, nitrate, disinfection byproducts (trihalomethanes and haloacetic acids), and coliform bacteria, and it sampled for 29 PFAS under UCMR5. EPA's UCMR5 data for JEA's Major Grid show no PFOA or PFOS above the 4 ppt reporting limit and low levels of two short-chain PFAS (PFPeA and PFPeS). JEA's latest report also flags chloride above the 250 mg/L secondary (taste) standard in part of the Major Grid.
Do I need a water filter in Jacksonville if JEA's water meets EPA standards? Meeting EPA standards means the water is legally safe to drink, but it doesn't mean zero contaminants. If you're in a high-risk group (pregnant, young children, immunocompromised), if your home has old plumbing that could leach lead, or if you want near-zero PFAS, a certified filter is the safest option. We recommend at minimum a certified carbon block filter for lead and PFOA/PFOS, or reverse osmosis for the short-chain PFAS JEA detected and maximum removal.
Does the Floridan Aquifer naturally filter out PFAS? The Floridan Aquifer's limestone provides natural filtration for sediment and some bacteria, but PFAS are synthetic chemicals that don't break down in natural systems. A 2022 USGS study of five eastern U.S. aquifer systems found PFAS in 60% of sampled public-supply wells, often tied to urban land use and fire-training areas, so groundwater isn't immune. JEA's plants use aeration, ozone (at two plants) and chlorine, not activated carbon, so neither the aquifer nor JEA's treatment removes PFAS.
What's the best water filter for PFAS removal in Jacksonville? For PFAS removal, we recommend reverse osmosis systems like the APEC ROES-50 (WQA-certified to NSF/ANSI 58; APEC says it reduces PFOA and PFOS) or carbon block filters like the Aquasana AQ-5200 (certified for PFOA/PFOS reduction under NSF/ANSI 53). Reverse osmosis is more effective, especially for short-chain PFAS, but sends water down the drain (older designs waste 3-4 gallons per gallon filtered). Carbon block wastes no water and retains beneficial minerals.
How often should I replace my water filter in Jacksonville? Replacement schedules depend on filter type and usage. Carbon block filters (like Aquasana) should be replaced every 6 months or 500 gallons per manufacturer guidelines. Reverse osmosis systems need sediment and carbon pre-filter changes every 6-12 months and membrane replacement every 2-3 years. Pitcher filters follow their rated capacity (about 6 months for a Brita Elite); ZeroWater filters run out faster in Jacksonville's very hard water, so swap them when the included meter reads 006.
