The short answer for Lake Elmo

Lake Elmo tap water has 2 contaminants above EPA guidelines, including PFOA at 3.0× the limit (tested August 2023). See the full compound-by-compound breakdown and filter recommendations.

The health risk for Lake Elmo

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 55042 Tap Water

What contaminants are above EPA limits in ZIP 55042?

ZIP 55042 has 2 contaminants above EPA health guidelines in the latest available data, including PFOA at 3.0x the EPA guideline. The full table on this page lists every tested compound and its measured level.

Will boiling ZIP 55042 tap water remove PFOA?

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 PFOA?

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 55042?

Public records identify LAKE ELMO as a primary water system associated with ZIP 55042. Service boundaries can vary by address, so confirm exact service with the utility.

When was ZIP 55042 tap water last tested?

The most recent test date used in this report is August 2023. EnviroClarity last refreshed this page on 2026-05-05.

Where can I find the official water quality report for ZIP 55042?

Every U.S. public water system is required to publish an annual Consumer Confidence Report (CCR). Contact LAKE ELMO or visit their website for the latest official report covering ZIP 55042. The EPA also maintains a national CCR locator.
