ScoreYourWater.com gives no verdict on your tap water; it shows what the public records say, as of October 14, 2026: EPA and Florida DEP data (2015-2025) for West Palm Beach's four main utilities list two contaminants above published health guidelines between them, and 3 of the 4 utilities had at least one health-based violation since July 1, 2021. Under EPA's 2024 PFAS rule, water systems must meet the PFOA and PFOS limits (4.0 ppt each) by April 2029; in May 2026 EPA proposed allowing extensions to April 2031. Results before then are monitoring data, not violations. This is public data, not a test of your tap.

Public data from EPA SDWA, EPA UCMR and Florida DEP, 2015-2025. Guidelines are California OEHHA public health goals (arsenic, 2004; chromium (hexavalent), 2011). It isn't a test of your tap, and your water can differ.
Health-based violations (EPA SDWIS): 3 of the 4 utilities had at least one health-based violation since July 1, 2021. Each utility's report lists them. Source: EPA SDWA bulk extract, July to September 2026.
A legal limit is an enforceable standard set by EPA under the Safe Drinking Water Act. Limits weigh health research together with the cost and feasibility of treatment. A health guideline is published by public-health sources and based on health research alone. The guidelines used here come from California OEHHA; they are not Florida or federal legal limits and are not enforceable. A utility can meet every legal limit and still be above a published health guideline.
West Palm Beach is served by four main utilities, so the utility results differ by ZIP. What changes by ZIP is which utility is the main one, the confidence of that match, and the housing mix. Your water bill names your utility.

Our systems aren't certified for PFAS.
EPA's 2024 rule sets a limit of 4.0 parts per trillion each for PFOA and PFOS; water systems must meet it by April 2029. In May 2026 EPA proposed allowing extensions to April 2031.

The level shown is the average of all of the utility's results in the years shown, with results below EPA's reporting level counted as zero. The highest single result and the number of samples in which it was detected are shown with each level. Each of these averaged above 4.0 ppt across all of the utility's samples, with results below the reporting level counted as zero. EPA judges compliance on a running annual average at each sampling point, so our combined average is a guide, not a compliance result. Under EPA's 2024 PFAS rule, water systems must meet the PFOA and PFOS limits (4.0 ppt each) by April 2029; in May 2026 EPA proposed allowing extensions to April 2031. Results before then are monitoring data, not violations.
Public data from EPA UCMR 5, 2024–2025. It isn't a test of your tap, and your water can differ. Last checked against the Federal Register: October 25, 2026.
0 means every sample was below EPA's UCMR 5 minimum reporting level (4 ppt for PFOA and PFOS); it does not mean none is present. Averages count those samples as 0, as on our utility pages.

The utilities' own Consumer Confidence Reports are the primary record. Each of these utilities publishes an annual Consumer Confidence Report. If you want your own tap tested, use a state-certified laboratory (Florida Department of Health lists them). ZIP reports describe the utility's public results, not your home's plumbing.
Approximate service area from EPA's Community Water System Service Area Boundaries; some boundaries are modeled estimates. Your water bill names your utility.
Solid: EPA has this type of record for the system. Grey: it does not.
We don't give a safe or unsafe verdict. Here is what the public data shows: EPA and Florida DEP data (2015-2025) show West Palm Beach's four main utilities with two contaminants above published health guidelines between them. EPA's records list health-based violations at 3 of them since July 1, 2021; see each utility's report for the list. A guideline and a legal limit are different things, and this is public data, not a test of your tap.
West Palm Beach has 17 scored ZIP codes. The main utility is City of West Palm Beach Water Utilities for 9, Palm Beach County Water Utilities for 6, Riviera Beach Utility Special District for 1 and Seacoast Utility Authority for 1 of them. EPA SDWA records show none of them buys water from another system. Your water bill names your utility.
Legal limits and health guidelines are set differently. A legal limit weighs health research together with cost and feasibility; a health guideline is based on health research alone. A utility can meet every legal limit and still be above a published guideline.
EPA's UCMR 5 data lists PFOS and PFOA at averages of 0 and 0 ppt for City of West Palm Beach Water Utilities (2023-2024), 7.38 and 3.71 ppt for Palm Beach County Water Utilities (2024-2025), 27 and 13.5 ppt for Riviera Beach Utility Special District (2024-2025) and 0 and 0 ppt for Seacoast Utility Authority (2024). 0 means every sample was below EPA's UCMR 5 minimum reporting level (4 ppt for PFOA and PFOS); it does not mean none is present. Averages count those samples as 0, as on our utility pages. Under EPA's 2024 PFAS rule, water systems must meet the PFOA and PFOS limits (4.0 ppt each) by April 2029; in May 2026 EPA proposed allowing extensions to April 2031. Results before then are monitoring data, not violations. This is public data, not a test of your tap.
Test results cover 2015-2025, and EPA compliance records come from the July to September 2026 extract. Data may be one to three years old and may not reflect the water at your tap.
