SCWA – Laguna/Vineyard water quality
Vineyard, CA · serves 188,417 people (51,882 connections) · Surface water · Local government · EPA ID CA3410029
Data: U.S. EPA · How we read the data · How we check it
Buys water from City of Sacramento Main. 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 limitPFOA, PFOS above the federal limit in EPA's 2023–2025 testing (PFOA 9.7 ppt vs a limit of 4 ppt, PFOS 15.5 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 – Laguna/Vineyard'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: 19 entry points tested Feb 2024 to Oct 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 Above limit Limit 4 ppt | 9.7 ppt 2.42× the limit |
| PFOS Above limit Limit 4 ppt | 15.5 ppt 3.86× the limit |
| PFHxS Detected, below limit Limit 10 ppt | 4.2 ppt 42% of the limit |
| 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) Detected, below limit Limit 1 | 0.42 |
| PFBS Detected, below limit Guideline 2,000 ppt | 2.4 ppt |
| PFBA Not detected Guideline 6,000 ppt | – |
| PFHxA Detected, below limit Guideline 3,000 ppt | 7.6 ppt |
| PFPeA Detected, no limit | 9.3 ppt |
| PFHpA Detected, no limit | 4.95 ppt |
What the utility says it is doing: The agency's 2025 water quality report says it takes wells that exceed state PFAS notification levels offline for emergency use only. It lists four wells (Banyan, Duck Slough, Feather Creek, Big Horn North) that did not serve the system in 2025.

For context: the PFOA average is higher than at 95% of the California systems EPA tested and the PFOS average is higher than at 93% of the California systems EPA tested.
29 PFAS tested, 7 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

Lead and copper

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.
Earlier EPA testing (2013–2020)
| Contaminant | Highest | Guideline |
|---|---|---|
| Manganese | 25 ppb | 300 ppb |
| Chromium-6 | 10 ppb | – |
| Vanadium | 34 ppb | 21 ppb |
| Strontium | 0.5 ppm | 1.5 ppm |
| Molybdenum | 2 ppb | 40 ppb |

Questions
Is SCWA – Laguna/Vineyard water safe to drink?
SCWA – Laguna/Vineyard has 1 unresolved health-based violation on record. EPA testing found PFAS above the 2024 federal limits, which systems must meet by 2029. Federal data can't tell you about your own pipes: lead comes from service lines and plumbing, so test your tap if your home was built before 1986. For the official word, read the utility's annual Consumer Confidence Report.
Does SCWA – Laguna/Vineyard water have PFAS?
Yes. EPA's 2023–2025 testing of SCWA – Laguna/Vineyard found 7 PFAS at least once. The highest entry-point averages were above the federal limit for PFOA and PFOS: PFOA 9.7 ppt, PFOS 15.5 ppt (limit 4 ppt for PFOA and PFOS, 10 ppt for the others).
What is the lead level in SCWA – Laguna/Vineyard water?
The most recent 90th-percentile lead result for SCWA – Laguna/Vineyard is 0 ppb, for the period ending Dec 2025. The federal action level is 15 ppb, falling to 10 ppb in November 2027. The 90th percentile means 9 in 10 homes sampled were at or below this number. Individual homes can be higher.
