Is Brookston tap water safe to drink?
- Arrowhead, MN
- Culver, MN
- Stoney Brook, MN
- Brookston
The short answer for Brookston
Brookston tap water has 3 detected contaminants, currently below EPA limits (tested October 2023). Lithium measured closest to the threshold. See the full compound-by-compound report.
The health risk for Brookston
- PFAS or other chemicals detected; no confirmed exceedances in multiple samples.
Lithium 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 55711 Tap Water
What's in ZIP 55711 tap water?
ZIP 55711 has 3 detected contaminants below EPA limits in this dataset. Lithium measured closest to its guideline.
Will boiling ZIP 55711 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 55711?
Public records identify Colonial Homes 2 as a primary water system associated with ZIP 55711. Service boundaries can vary by address, so confirm exact service with the utility.
When was ZIP 55711 tap water last tested?
The most recent test date used in this report is December 2023. EnviroClarity last refreshed this page on 2026-05-05.
Where can I find the official water quality report for ZIP 55711?
Every U.S. public water system is required to publish an annual Consumer Confidence Report (CCR). Contact Colonial Homes 2 or visit their website for the latest official report covering ZIP 55711. The EPA also maintains a national CCR locator.
