What this means for you

Is it safe to drink right now?: EPA records show 1 recent health-based violation for Lamoille that is not marked resolved. Check your utility’s website or bill insert for any boil-water or do-not-drink notice and follow it.
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. Unresolved health-based issues make a home filter a reasonable backup.
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.

Summary: 2 health-based violations in the last 5 years; 2 monitoring/reporting violations; 1 not yet resolved; No UCMR 5 PFAS results on file; Lead 90th percentile ABOVE the action level (2026).
