What this means for you

Is it safe to drink right now?: EPA records show 3 recent health-based violations for City of Zavalla that are 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. Unresolved health-based issues make a home filter a reasonable backup.
What kind of filter?: If bacteria are the issue, follow any boil notice; NSF/ANSI 55 Class A UV can help after the notice ends. 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.
