Data: U.S. EPA · How we read the data · How we check it
Buys water from Sacramento Suburban Water District. Treated water bought from another system can carry that system's contaminants.
Summary
PFAS above the 2024 federal limits, plus an unresolved health-based violation. Systems have until 2029 to meet the PFAS limits.
Is it an emergency? No: these findings are about longer-term exposure, and nothing in EPA's data calls for you to stop drinking the water today. If your utility ever issues a boil-water or do-not-drink notice, follow it.
- PFAS
- Above limitPFOS above the federal limit in EPA's 2023–2025 testing (PFOS 7.15 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
- Lead
- Below action level0 ppb (parts per billion) at the 90th percentile: 9 in 10 homes sampled were at or below it. Action level 15 ppb, falling to 10 ppb in Nov 2027. Monitoring period ending Dec 2025. Your home's pipes can make yours higher.
- Violations
- 1 unresolved1 health-based violation since 2016, most recently Oct 2024.
- Pregnant, or mixing baby formula with tap water? Babies drink more water for their size, so PFAS exposure matters more for them. Consider bottled water or a filter certified for PFAS for formula, and ask your doctor. Health effects.
- To lower your PFAS exposure now, a home filter certified for PFAS reduction works (reverse osmosis, or activated carbon certified to NSF/ANSI 53 or 58). Filters for these results.
- Built before 1986, or not sure what your service line is made of? Check your service line and test your tap. Utility data can't show your pipes.
- Tested your own tap? Compare your result with these numbers. Moving? Compare this system with another.
- Read SCWA – Arden Park Vista's annual water quality report (Consumer Confidence Report). It lists every regulated contaminant tested and is usually on the utility's website or mailed with your bill, and you can also request it at (916) 875-2216. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 10 entry points tested Nov 2024 to Nov 2025. "Average" is the highest entry-point average (non-detects counted as zero), the way EPA compares UCMR 5 results to the limits. ppt = parts per trillion. These results do not determine compliance.
| Contaminant | Highest average |
|---|---|
| PFOA One sample above limit Limit 4 ppt | 2.75 ppt 69% of the limit |
| PFOS Above limit Limit 4 ppt | 7.15 ppt 1.79× the limit |
| PFHxS Not detected Limit 10 ppt | – |
| PFNA Not detected Limit 10 ppt | – |
| HFPO-DA (GenX) Not detected Limit 10 ppt | – |
| Hazard Index (a combined score for PFHxS, PFNA, GenX and PFBS, where above 1 is over the limit) Not detected Limit 1 | – |
| PFBS Not detected Guideline 2,000 ppt | – |
| PFBA Not detected Guideline 6,000 ppt | – |
| PFHxA Not detected Guideline 3,000 ppt | – |
| PFPeA Detected, no limit | 1.8 ppt |
For context: the PFOS average is higher than at 87% of the California systems EPA tested.
29 PFAS tested, 3 detected at least once. "Not detected" means below EPA's reporting limit (about 2 to 20 ppt depending on the chemical), not proven zero. PFAS not listed were not detected. The limits for PFHxS, PFNA, GenX and the Hazard Index were proposed for rescission in May 2026. That proposal is not final. Systems have until 2029 to meet the limits.
Lithium
Not detected in 20 samples (reporting limit 9 ppb). About lithium.
Lead and copper
Latest 90th percentile: 0 ppb lead (Jan 2023 – Dec 2025). Below action level
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2023 – Dec 2025 | 0 ppb |
| Jan 2020 – Dec 2022 | 0 ppb |
| Jan 2017 – Dec 2019 | 0 ppb |
Earlier results (9)
| Jan 2014 – Dec 2016 | 0 ppb |
| Jan 2011 – Dec 2013 | 0 ppb |
| Jan 2008 – Dec 2010 | 0 ppb |
| Jan 2007 – Dec 2007 | 19 ppb |
| Jan 2004 – Dec 2004 | 0 ppb |
| Jan 2001 – Dec 2003 | 0 ppb |
| Jan 2001 – Dec 2001 | 0 ppb |
| Jan 1998 – Dec 2000 | 2 ppb |
| Jan 1999 – Dec 1999 | 2 ppb |
Lead comes from pipes and fixtures, not the source water, so it varies home to home. The 90th percentile means 9 in 10 sampled homes were at or below it. More on lead.
Violations
| When | What happened |
|---|---|
| Oct 2024 | The system did not publish the required inventory of lead service lines (due October 2024). It says nothing about lead levels in the water. EPA record: Lead and copper rule revisions · LSL Inventory Unaddressed |
1 unresolved monitoring or reporting violation: Lead and copper rule revisions.
Health-based violations mean a contaminant exceeded a limit or a required treatment step was missed. Monitoring and reporting violations mean required tests or reports were late or missing, so the water's quality during that time is unknown. The total includes every violation in EPA's records, most of them paperwork.
