Frequently Asked Questions about ZIP 34945 Tap Water

What contaminants are above EPA limits in ZIP 34945?

ZIP 34945 has 5 contaminants above EPA health guidelines in the latest available data, including PFOS at 3.0x the EPA guideline. The full table on this page lists every tested compound and its measured level.

Will boiling ZIP 34945 tap water remove PFOS?

No. Boiling does not remove PFAS, and the compounds can actually become more concentrated as water evaporates. To reduce PFAS at home, use a filter independently certified to NSF/ANSI P473 (activated-carbon pitcher or under-sink) or NSF/ANSI 58 (reverse osmosis).

Do basic pitcher filters remove PFOS?

Most basic pitcher filters are only certified to NSF/ANSI 42 or 53, which do not cover PFAS. Look for a filter independently certified to NSF/ANSI P473 (activated-carbon pitcher or under-sink) or NSF/ANSI 58 (reverse osmosis) on the spec sheet.

Who provides tap water in ZIP 34945?

Public records identify FT. PIERCE UTILITIES AUTHORITY as a primary water system associated with ZIP 34945. Service boundaries can vary by address, so confirm exact service with the utility.

When was ZIP 34945 tap water last tested?

The most recent test date used in this report is September 2025. EnviroClarity last refreshed this page on 2026-05-05.

Where can I find the official water quality report for ZIP 34945?

Every U.S. public water system is required to publish an annual Consumer Confidence Report (CCR). Contact FT. PIERCE UTILITIES AUTHORITY or visit their website for the latest official report covering ZIP 34945. The EPA also maintains a national CCR locator.
