This utility: 0.36 ppbaverage of all sampleshighest sample 1.6 ppbdetected in 3 of 10 samples
Legal limit: 10 ppb
Health guideline: 0.004 ppb

Arsenic: a natural element that enters water from rock and soil deposits and from some orchard and industrial runoff. California OEHHA set a 0.004 ppb public health goal in 2004 to limit lung and bladder cancer risk; EPA's enforceable limit is 10 ppb (in effect since 2006). Source: California OEHHA

Lead

Lead: 3 ppb (90th percentile of tap samples, January to December 2025). 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.

Which water utility serves ZIP 33401?

City of West Palm Beach Water Utilities (EPA water system FL4501559) is the main utility for ZIP 33401, based on EPA Water System Boundaries (CWS service area boundaries) v3.0, March 2026 release overlaid on Census ZIP code areas. Your water bill names your utility.

Does the utility serving ZIP 33401 buy water from another system?

No. EPA SDWA records (July to September 2026 extract) show no water purchases by City of West Palm Beach Water Utilities from another system.

How many contaminants in ZIP 33401 are above published health guidelines?

1 of 16 detected contaminants were above their published health guidelines in EPA SDWA, EPA UCMR and Florida DEP data, 2018-2025. The highest: Arsenic at 90 times its guideline.

How is the Water Score for ZIP 33401 calculated?

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 is 92, so the score is 92.

What is the difference between a health guideline and a legal limit?

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.

How recent is the data for ZIP 33401?

Test results cover 2018-2025. 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.
