Which water utility serves ZIP 33410?

Seacoast Utility Authority (EPA water system FL4501124) is the main utility for ZIP 33410, 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 33410 buy water from another system?

No. EPA SDWA records (July to September 2026 extract) show no water purchases by Seacoast Utility Authority from another system.

How many contaminants in ZIP 33410 are above published health guidelines?

None of the 9 detected contaminants were above their published health guidelines in EPA SDWA, EPA UCMR and Florida DEP data, 2018-2025.

How is the Water Score for ZIP 33410 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.

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.
