The short answer for Mauston

Mauston tap water has 3 detected contaminants, currently below EPA limits (tested June 2025). 8:2 FTS measured closest to the threshold. See the full compound-by-compound report.

The health risk for Mauston

PFAS traces were detected in local water tests, though levels are currently below EPA limits. Since no amount of PFAS is considered completely safe by health researchers, a certified filter adds a meaningful layer of protection, especially for children.

PFAS or other chemicals detected; no confirmed exceedances in multiple samples.

Frequently Asked Questions about ZIP 53948 Tap Water

What's in ZIP 53948 tap water?

ZIP 53948 has 3 detected contaminants below EPA limits in this dataset. 8:2 FTS measured closest to its guideline.

Will boiling ZIP 53948 tap water remove 8:2 FTS?

Boiling tap water can kill many pathogens, but it does not remove most chemical contaminants tracked in EPA monitoring. Several dissolved contaminants can even concentrate as water evaporates. For the chemical contaminants reported in ZIP 53948, a certified filter is more reliable.

Do basic pitcher filters remove 8:2 FTS?

Basic pitcher filters are typically rated for chlorine, taste, and odor (NSF/ANSI 42), not for the broader list of contaminants tracked in EPA monitoring. Match the certification (NSF/ANSI 42, 53, 58, or P473) to the specific compounds listed in this report before assuming a filter helps.

Who provides tap water in ZIP 53948?

Public records identify MAUSTON WATERWORKS as a primary water system associated with ZIP 53948. Service boundaries can vary by address, so confirm exact service with the utility.

When was ZIP 53948 tap water last tested?

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

Where can I find the official water quality report for ZIP 53948?

Every U.S. public water system is required to publish an annual Consumer Confidence Report (CCR). Contact MAUSTON WATERWORKS or visit their website for the latest official report covering ZIP 53948. The EPA also maintains a national CCR locator.
