Summary
No federal limits exceeded in EPA data.
- PFAS
- Not detectedNone of 29 PFAS found above EPA's reporting limits in 40 samples (2023–2025).
- Lithium
- Above screening levelHighest result 42 ppb. EPA uses 10 ppb to decide what to study further. It is not a health limit, and there is no federal limit for lithium. About 1 in 4 systems tested were above it.
- Lead
- Below action level1.2 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
- None health-basedNo health-based violations since 2016.

PFAS (“forever chemicals”)
EPA UCMR 5: 20 entry points tested Jun 2024 to Jun 2026. "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 Not detected Limit 4 ppt | – |
| PFOS Not detected Limit 4 ppt | – |
| 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 | – |
29 PFAS tested, 0 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
Detected in 33 of 40 samples. Highest result 42 ppb. EPA's non-enforceable screening level is 10 ppb. Above screening level The screening level is how EPA decides what to study further, not a health limit. There is no federal limit for lithium and no filter is certified to remove it. About lithium.
Lead and copper
Latest 90th percentile: 1.2 ppb lead (Jan 2023 – Dec 2025). Below action level
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2023 – Dec 2025 | 1.2 ppb |
| Jan 2020 – Dec 2022 | 1.1 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 | 0 ppb |
| Jan 2004 – Dec 2004 | 5 ppb |
| Jan 2001 – Dec 2003 | 0 ppb |
| Jan 2002 – Dec 2002 | 5 ppb |
| Jan 2001 – Dec 2001 | 5 ppb |
| Jan 1998 – Dec 2000 | 0 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
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 | 11 ppb | 300 ppb |
| Strontium | 0.97 ppm | 1.5 ppm |
| Chromium-6 | 7.2 ppb | – |
| 1,4-Dioxane | 1.7 ppb | 0.35 ppb |
| Chlorate | 510 ppb | 210 ppb |
| Vanadium | 19 ppb | 21 ppb |
| Molybdenum | 19 ppb | 40 ppb |

Questions
Is California Water Service Salinas water safe to drink?
California Water Service Salinas has no health-based violations since 2016. EPA testing found no PFAS above the federal limits. 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 California Water Service Salinas water have PFAS?
EPA tested California Water Service Salinas for 29 PFAS between Jun 2024 and Jun 2026 and none were detected above the reporting limits (about 2 to 20 ppt depending on the chemical).
What is the lead level in California Water Service Salinas water?
The most recent 90th-percentile lead result for California Water Service Salinas is 1.2 ppb, for the period ending Dec 2025. The federal action level is 15 ppb, falling to 10 ppb in November 2027.
