What this means for you

Is it safe to drink right now?: Based on the latest EPA data, Halifax Water Department has no unresolved health-based violations from the past year. Water that meets federal standards is generally considered safe to drink for most healthy people.
Should I use a filter?: Yes, we recommend considering one. Average PFOA was above the 4 ppt federal limit (compliance deadline April 2029).
What kind of filter?: For PFAS, look for NSF/ANSI 53 (with an explicit PFOA/PFOS or total PFAS claim) or NSF/ANSI 58 reverse osmosis. 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: No health-based violations in the last 5 years; 50 monitoring/reporting violations; PFOA/PFOS average above the 4 ppt federal limit: PFOA; Lead 90th percentile below the action level (2023).
