Is Huntington Beach, CA tap water safe?
Supplied by City of Huntington Beach · serves 201,000 people (53,432 connections) · Purchased surface water · EPA ID CA3010053
Data: U.S. EPA · How we read the data · How we check it
Buys water from Metropolitan Water District of SO. Cal., City of Fountain Valley, City of Seal Beach, City of Westminster. Treated water bought from another system can carry that system's contaminants.
Summary
PFAS above the 2024 federal limits. Systems have until 2029 to meet the PFAS limits.
Is it an emergency? No: PFAS limits are about years of exposure, not a glass of water, 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 5.5 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
- Lithium
- Above screening levelHighest result 36 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.
- 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 City of Huntington Beach'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 (714) 536-5503. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 10 entry points tested Mar 2023 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 Above limit Limit 4 ppt | 5.5 ppt 1.38× the limit |
| PFHxS Detected, below limit Limit 10 ppt | 1.65 ppt 17% 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 | 0.17 |
| PFBS Not detected Guideline 2,000 ppt | – |
| PFBA Not detected Guideline 6,000 ppt | – |
| PFHxA Not detected Guideline 3,000 ppt | – |
For context: the PFOS average is higher than at 85% of the California systems EPA tested.
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 3 of 22 samples. Highest result 36 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: 7 ppb (Dec 2018).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2022 – Dec 2024 | 0 ppb |
| Jan 2019 – Dec 2021 | 1.9 ppb |
| Jan 2016 – Dec 2018 | 7 ppb |
Earlier results (9)
| Jan 2013 – Dec 2015 | 0 ppb |

| Jan 2001 – Dec 2003 | 2 ppb |
| Jan 2000 – Dec 2000 | 4 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 | 20.1 ppb | 300 ppb |
| Molybdenum | 6.8 ppb | 40 ppb |
| Vanadium | 6.4 ppb | 21 ppb |
| Chlorate | 99.9 ppb | 210 ppb |
| Strontium | 1.24 ppm | 1.5 ppm |
| 1,4-Dioxane | 1.18 ppb | 0.35 ppb |

Questions
Is Huntington Beach tap water safe to drink?
Most of Huntington Beach gets its water from City of Huntington Beach. City of Huntington Beach has no health-based violations since 2016.

For the official word, read the utility's annual Consumer Confidence Report.
