- Should I use a filter?

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: 4 health-based violations in the last 5 years; 40 monitoring/reporting violations; 3 not yet resolved; PFAS tested (UCMR 5), none above federal limits; Lead 90th percentile below the action level (2025).
