The ink line is the federal legal limit. Log scale: each step right is ten times more.
Health guidelines: Chromium-6, California OEHHA 2011.

Legal limits weigh health research together with cost and treatment feasibility; health guidelines are based on health research alone. A utility can meet every legal limit and still be above health guidelines. Source: EPA SDWA, EPA UCMR and Florida DEP data, 2015-2025.
Each bar is the level reported for ZIP 33404. It is drawn against its own health guideline, so rows are not comparable with each other.

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.
Lead: 2.4 ppb (90th percentile of tap samples, January to December 2023). EPA action level (90th percentile): 15 ppb.
Lead is measured at the tap in homes selected because they are most likely to have lead plumbing. EPA says lead in drinking water mainly comes from pipes, solder and fixtures in service lines and buildings, not from the water source. Your home's plumbing matters more than the utility's number. EPA's goal (MCLG) for lead is zero.
California's public health goal for lead is 0.2 ppb.
If your home is older or may have a lead service line, ask your utility (it must keep a service-line inventory) or have your tap tested by a state-certified lab.

A legal limit is an enforceable standard, set by the 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. A utility can meet every legal limit and still be above a published health guideline.

Return-to-compliance dates are the dates of EPA's "compliance achieved" actions. "None recorded" means EPA's July to September 2026 extract lists no such action for that violation.
The score starts at 100. It goes down 8 for each contaminant above a cited health guideline whose source states a cancer basis, 5 for each other contaminant above its cited guideline, 5 for each of PFOA and PFOS averaging above the 4.0 ppt limit in EPA's 2024 PFAS rule, 10 for each contaminant whose average of all samples is above EPA's legal limit (instead of its guideline step), and 1 for each contaminant with a cited cancer-based guideline that is detected below it. Only guidelines with a cited document count. The lowest score is 5. Higher is better.

Riviera Beach Utility Special District (EPA water system FL4501229) is the main utility for ZIP 33404, based on EPA Water System Boundaries (CWS service area boundaries) v3.0, March 2026 release overlaid on Census ZIP code areas. ZIP codes can cross utility lines, so check your water bill. Your water bill names your utility.
No. EPA SDWA records (July to September 2026 extract) show no water purchases by Riviera Beach Utility Special District from another system.
1 of 27 detected contaminants were above their published health guidelines in EPA SDWA, EPA UCMR and Florida DEP data, 2015-2025. The highest: Chromium (hexavalent) at 9.5 times its guideline. PFOA and PFOS averaged above 4.0 ppt, the limit in EPA's 2024 PFAS rule (water systems must meet it by April 2029; EPA has proposed allowing until 2031).
The score starts at 100. It goes down 8 for each contaminant above a cited health guideline whose source states a cancer basis, 5 for each other contaminant above its cited guideline, 5 for each of PFOA and PFOS averaging above the 4.0 ppt limit in EPA's 2024 PFAS rule, 10 for each contaminant whose average of all samples is above EPA's legal limit (instead of its guideline step), and 1 for each contaminant with a cited cancer-based guideline that is detected below it. Only guidelines with a cited document count. The lowest score is 5. Higher is better. For this report: 100 minus 8 times 1, minus 5 times 2 (PFOA and PFOS average above 4.0 ppt, the limit in EPA's 2024 PFAS rule) is 82, so the score is 82.
A legal limit is an enforceable standard, set by the 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. A utility can meet every legal limit and still be above a published health guideline.
Test results cover 2015-2025. EPA compliance records come from the July to September 2026 extract. Data may be one to three years old and may not reflect water at your tap.
We don't give a safe or unsafe verdict. Here is what the public records show for Riviera Beach Utility Special District: 1 of 27 detected contaminants were above the health guidelines we use (2015-2025), 1 health-based violation was recorded since July 1, 2021 (EPA SDWIS), and the Water Score is 82/100. These records can be one to three years old and may not reflect the water at your tap. Its PFOA or PFOS results averaged above 4.0 ppt, the level EPA set in 2024 (not yet enforceable). Details are in the full report. Our systems aren't certified for PFAS. That isn't a clean bill of health or a health finding. EPA's national files don't hold sample results for most regulated contaminants. For health questions, ask your utility or your doctor.
