The short answer for Princeton

Princeton tap water has PFOS above EPA guidelines at 1.2× the limit (tested October 2024). See the full report with all tested compounds and filter options.

The health risk for Princeton

PFAS ('forever chemicals') have been detected above EPA limits in this water system's most recent tests. These synthetic chemicals do not break down in the body and are linked to a range of health effects. A certified filter is strongly recommended.

Frequently Asked Questions about ZIP 55371 Tap Water

What contaminants are above EPA limits in ZIP 55371?

ZIP 55371 has PFOS above EPA health guidelines in the latest available data at 1.2x the EPA guideline. The full table on this page lists every tested compound and its measured level.

Will boiling ZIP 55371 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 55371?

Public records identify PRINCETON as a primary water system associated with ZIP 55371. Service boundaries can vary by address, so confirm exact service with the utility.

When was ZIP 55371 tap water last tested?

The most recent test date used in this report is October 2024. EnviroClarity last refreshed this page on 2026-05-05.

Where can I find the official water quality report for ZIP 55371?

Every U.S. public water system is required to publish an annual Consumer Confidence Report (CCR). Contact PRINCETON or visit their website for the latest official report covering ZIP 55371. The EPA also maintains a national CCR locator.
