Tap water quality for ZIP 59851
13 community water systems linked to this ZIP, largest first.
What this means for you in ZIP 59851
- Is it safe to drink right now?
- The system’s latest lead 90th-percentile result is above today’s 15 ppb action level. That does not mean every home is over the limit — lead often comes from plumbing in the building — but it is a red flag. Flush cold water before drinking and consider a certified lead filter until you can test your own tap.
- Should I use a filter?
- Yes, we recommend considering one. Lead results are high enough that a certified lead-reduction filter is a sensible precaution.
- What kind of filter?
- For lead, choose NSF/ANSI 53 certified for lead reduction (or RO under 58). See matched standards and product picks.
This is general information from public EPA data, not medical advice. Lead often comes from a home’s own pipes, so only a test of your tap can tell your exposure. If you are pregnant, caring for an infant, or have a weakened immune system, ask your doctor or health department.
