- lithium above limit.
Arsenic 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 56537 Tap Water
What contaminants are above EPA limits in ZIP 56537?
ZIP 56537 has 3 contaminants above EPA health guidelines in the latest available data, including Arsenic at 4.3x the EPA guideline. The full table on this page lists every tested compound and its measured level.
Will boiling ZIP 56537 tap water remove Arsenic?
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 56537, a certified filter is more reliable.
Do basic pitcher filters remove Arsenic?
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 56537?
Public records identify FERGUS FALLS as a primary water system associated with ZIP 56537. Service boundaries can vary by address, so confirm exact service with the utility.
