What this means for you
- Is it safe to drink right now?
- EPA records show 1 recent health-based violation for Big Park Water Company that is not marked resolved. Check your utility’s website or bill insert for any boil-water or do-not-drink notice and follow it.
- Should I use a filter?
- Yes, we recommend considering one. Average PFOA was above the 4 ppt federal limit (compliance deadline April 2029). Unresolved health-based issues make a home filter a reasonable backup.
- 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. If bacteria are the issue, follow any boil notice; NSF/ANSI 55 Class A UV can help after the notice ends. 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: 7 health-based violations in the last 5 years; 148 monitoring/reporting violations; 3 not yet resolved; PFOA/PFOS average above the 4 ppt federal limit: PFOA; Lead 90th percentile below the action level (2024).
