What this means for you

Is it safe to drink right now?: Based on the latest EPA data, SCWA - Arden Park Vista 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 PFOS 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: 1 health-based violation in the last 5 years; 1 monitoring/reporting violation; 2 not yet resolved; PFOA/PFOS average above the 4 ppt federal limit: PFOS; Lead 90th percentile below the action level (2025).
