City of Calvert
What this means for you
- Is it safe to drink right now?
- Based on the latest EPA data, City of Calvert 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?
- Optional. Nothing in this data strongly calls for one. Many people still filter for chlorine taste and odor.
- What kind of filter?
- For taste and odor (chlorine/chloramine), an NSF/ANSI 42 pitcher or faucet filter is enough. 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.
