Palm Beach County tap water: what EPA testing found
Palm Beach County Water Utilities (EPA record: PALM BEACH COUNTY WATER UTILITIES) serves 671,114 people in FL from ground water.
What the data shows
PFOA and PFOS above EPA’s drinking-water limit
In UCMR 5 testing (2024–2025), PFOA averaged up to 8.15 ng/L (limit 4.0); PFOS averaged up to 19 ng/L (limit 4.0) at the worst sampling point. Utilities must meet the limit by 2029 under the current rule; EPA has proposed letting systems ask for until 2031 (not final).
What fits: Pick a filter whose listing certifies PFOA/PFOS (or total PFAS) reduction under NSF/ANSI 53 or 58. Under-sink reverse osmosis units and some carbon filters and pitchers carry it; the certification for the exact model is what counts, not the filter type.

Coliform or groundwater-rule violation
1 health-based violation since 2016, the latest starting 2023-12-01.
What fits: Coliform and groundwater-rule violations are fixed at the system. Follow the utility’s notices; if it issues a boil-water advisory, boil or use bottled water until it is lifted.
Lead from home plumbing (not in this data)
UCMR 5 does not test for lead, and lead usually enters water from service lines and plumbing inside buildings. Your utility’s lead service line inventory says whether your address is served by a lead line.
What fits: Lead comes from lead service lines, solder and fixtures inside buildings, not usually from the treatment plant. Use a filter certified for lead reduction (NSF/ANSI 53 or 58) at the tap you drink from.

PFAS and lithium (EPA UCMR 5)
240 results from 4 sampling points, 6 Nov 2024 to 8 Aug 2025. Averages count results below EPA’s reporting level as zero, as the PFAS rule does. Every number links to EPA’s UCMR 5 Data Finder (search PWSID FL4504393). Limits: EPA PFAS rule.
| Contaminant | Detected in | Highest result | Average | EPA limit |
|---|---|---|---|---|
| PFOA | 4 of 8 | 9 ng/L | 3.71 ng/L | 4 ng/L |
| PFOS | 4 of 8 | 20 ng/L | 7.38 ng/L | 4 ng/L |
| PFHxS | 4 of 8 | 6.4 ng/L | 2.44 ng/L | 10 ng/L* |
| PFNA | 0 of 8 | not detected | 0 ng/L | 10 ng/L* |
| HFPO-DA | 0 of 8 | not detected | 0 ng/L | 10 ng/L* |
| PFBS | 4 of 8 | 6.1 ng/L | 2.33 ng/L | none |
| PFBA | 1 of 8 | 5 ng/L | 0.63 ng/L | none |
| PFHxA | 4 of 8 | 6.5 ng/L | 2.76 ng/L | none |

| 6:2 FTS | 1 of 8 | 13 ng/L | 1.63 ng/L | none |
| Lithium | 0 of 8 | not detected | 0 µg/L | none (screening level 10 µg/L) |
* PFHxS, PFNA and HFPO-DA limits (and the PFAS hazard index) are in the rule, but EPA proposed on 20 May 2026 to rescind them; not final as of 16 Oct 2026. UCMR 5 results are screening data, not compliance results: compliance uses quarterly running averages from 2029. Source file: EPA UCMR 5 occurrence data (dated 15 Oct 2026).

Hardness
The utility’s latest water report doesn’t publish a hardness figure (checked 16 Oct 2026). A home test kit or a call to the utility gives it; then use the softener calculator.
