The health risk for Marshall
- lithium, PFHxS above limit.
Lithium was detected above EPA limits. These filters are independently certified to reduce common drinking-water contaminants.
Here's what actually removes PFAS from your water
The right filter eliminates PFAS at the tap. But not all filters do - and the type you choose matters for your home.
Common pitchers like Brita do not remove PFAS. You need a filter independently certified to NSF P473 (for pitcher filters) or NSF/ANSI 58 (for reverse osmosis systems). All three options below carry the relevant certification.

Frequently Asked Questions about ZIP 56258 Tap Water
What contaminants are above EPA limits in ZIP 56258?
ZIP 56258 has 3 contaminants above EPA health guidelines in the latest available data, including Lithium at 12.3x the EPA guideline. The full table on this page lists every tested compound and its measured level.
Will boiling ZIP 56258 tap water remove Lithium?
No. Boiling tap water does not remove lithium. Lithium is a dissolved mineral, so heat does not break it down and evaporation can actually concentrate it. Reverse osmosis (NSF/ANSI 58) is the most reliable at-home option for reducing lithium.
Do basic pitcher filters remove Lithium?
Standard pitcher filters are not certified to reduce lithium. Reverse osmosis (NSF/ANSI 58) is the most widely available home option for reducing lithium in drinking water.
Who provides tap water in ZIP 56258?
Public records identify MARSHALL as a primary water system associated with ZIP 56258. Service boundaries can vary by address, so confirm exact service with the utility.
When was ZIP 56258 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 56258?
Every U.S. public water system is required to publish an annual Consumer Confidence Report (CCR). Contact MARSHALL or visit their website for the latest official report covering ZIP 56258. The EPA also maintains a national CCR locator.
