The short answer for Boulder CCD (59701)
Butte-Silver Bow (balance) tap water has 4 detected contaminants, currently below EPA limits (tested December 2025). Copper measured closest to the threshold. See the full compound-by-compound report.
The health risk for Butte-Silver Bow (balance)
- PFAS or other chemicals detected; no confirmed exceedances in multiple samples.
Copper 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 59701 Tap Water
What's in ZIP 59701 tap water?
ZIP 59701 has 4 detected contaminants below EPA limits in this dataset. Copper measured closest to its guideline.
Will boiling ZIP 59701 tap water remove Copper?
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 59701, a certified filter is more reliable.
Do basic pitcher filters remove Copper?
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 59701?
Public records identify BUTTE SILVERBOW WATER DEPT as a primary water system associated with ZIP 59701. Service boundaries can vary by address, so confirm exact service with the utility.
When was ZIP 59701 tap water last tested?
The most recent test date used in this report is June 2024. EnviroClarity last refreshed this page on 2026-05-05.
Where can I find the official water quality report for ZIP 59701?
Every U.S. public water system is required to publish an annual Consumer Confidence Report (CCR). Contact BUTTE SILVERBOW WATER DEPT or visit their website for the latest official report covering ZIP 59701. The EPA also maintains a national CCR locator.
