Is Columbus tap water safe to drink?
- Elba, WI
- Hampden, WI
- Calamus, WI
- York, WI
- Columbus
The short answer for Columbus
Columbus tap water has 1 detected contaminant, currently below EPA limits (tested May 2023). Nitrate + Nitrite measured closest to the threshold. See the full compound-by-compound report.
The health risk for Columbus
- PFAS or other chemicals detected; no confirmed exceedances in multiple samples.
Nitrate + Nitrite was detected below EPA limits. A certified filter can still add an extra layer of protection.
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.
No compounds above or close to EPA limits in available data.

Frequently Asked Questions about ZIP 53925 Tap Water
What's in ZIP 53925 tap water?
ZIP 53925 has 1 detected contaminant below EPA limits in this dataset. Nitrate + Nitrite measured closest to its guideline.
Will boiling ZIP 53925 tap water remove Nitrate + Nitrite?
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 53925, a certified filter is more reliable.
Do basic pitcher filters remove Nitrate + Nitrite?
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 53925?
Public records identify COLUMBUS WATER & LIGHT DEPARTMENT as a primary water system associated with ZIP 53925. Service boundaries can vary by address, so confirm exact service with the utility.
