What this means for you

Is it safe to drink right now?
Based on the latest EPA data, Avi Casino 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?
It's worth considering. Avi Casino has a D because of its violation record over the past 5 years (9 health-based), even though nothing is flagged as unresolved in the last year. A filter matched to the contaminants in its violation history is a reasonable precaution.
What kind of 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.
