Summary
No federal limits exceeded in EPA data.
- PFAS
- Detected, below limit2 of 29 PFAS found at least once. All averages below the federal limits.
- Lithium
- Above screening levelHighest result 53.5 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 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 2024. Your home's pipes can make yours higher.
- Violations
- None health-basedNo health-based violations since 2016.

- Read Goleta Water District'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 (805) 879-4621. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 10 entry points tested Dec 2024 to Sep 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 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 Detected, below limit Guideline 3,000 ppt | 4.3 ppt |
| PFPeA Detected, no limit | 5.8 ppt |
29 PFAS tested, 2 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 22 of 22 samples. Highest result 53.5 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: 0 ppb lead (Jan 2022 – Dec 2024). Below action level
Highest since 2016: 5.9 ppb (Dec 2018).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2022 – Dec 2024 | 0 ppb |
| Jan 2019 – Dec 2021 | 2.2 ppb |
| Jan 2016 – Dec 2018 | 5.9 ppb |
Earlier results (9)
| Jan 2013 – Dec 2015 | 0 ppb |
| Jan 2010 – Dec 2012 | 0 ppb |
| Jan 2007 – Dec 2009 | 0 ppb |
| Jan 2006 – Dec 2006 | 5 ppb |
| Jan 2004 – Dec 2006 | 0 ppb |
| Jan 2003 – Dec 2005 | 0 ppb |
| Jan 2003 – Dec 2003 | 5 ppb |
| Jan 2001 – Dec 2003 | 0 ppb |
| Jan 2000 – Dec 2002 | 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 | 170 ppb | 300 ppb |
| Strontium | 1.6 ppm | 1.5 ppm |
| 1,4-Dioxane | 0.1 ppb | 0.35 ppb |
| Chromium-6 | 0.85 ppb | – |
| Vanadium | 5.5 ppb | 21 ppb |
| Chlorate | 1,600 ppb | 210 ppb |
| Molybdenum | 11 ppb | 40 ppb |

Questions
Is Goleta tap water safe to drink?
Most of Goleta gets its water from Goleta Water District. Goleta Water District 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.
