EPA records for CITY OF NEWPORT BEACH • Updated October 2026
Grade A — based on EPA compliance records, lead testing and PFAS monitoring
CITY OF NEWPORT BEACH has a clean recent record: no health-based violations in the last five years and no lead, PFAS or historical monitoring result that costs it more than a few points.
EPA's compliance record for CITY OF NEWPORT BEACH shows no violations of any kind since 2016. The latest Lead and Copper Rule 90th-percentile result was 0 ppb (2024), below the 15 ppb action level. No PFAS were detected in 174 UCMR5 results (2023–2025).

Yes — by EPA's records Newport Beach, CA tap water is safe to drink and earns an A. The grade rests on no health-based EPA violations in the last five years and lead at 0 ppb (90th percentile, 2024) against the 15 ppb action level. Lead from your own service line or plumbing is the main risk city-level data cannot see, so homes built before 1986 should still test at the tap.
CITY OF NEWPORT BEACH's most recent Lead and Copper Rule result (2022-01-01 to 2024-12-31) was 0 ppb at the 90th percentile, below EPA's 15 ppb action level. Because lead usually comes from service lines and household plumbing, homes built before 1986 should still test at the tap.
No. None of the 174 UCMR5 PFAS results for CITY OF NEWPORT BEACH (2023-03-14 to 2024-01-23) were at or above the reporting limit of roughly 3–5 ppt.
No. EPA's SDWIS shows no violations of any kind for CITY OF NEWPORT BEACH since 2016.
CITY OF NEWPORT BEACH reports purchased surface water as its primary source and serves about 68,572 people (EPA PWSID CA3010023).
Not on the strength of EPA's data for CITY OF NEWPORT BEACH. A filter still helps with taste and with lead from your own plumbing, which no city-level test can measure.

EPA Lead and Copper Rule 90th-percentile results reported by CITY OF NEWPORT BEACH
Well below the 15 ppb action level. In the most recent monitoring period on file (2022-01-01 to 2024-12-31), 90% of the homes CITY OF NEWPORT BEACH sampled had lead at or below 0 ppb.
EPA's action level is 15 ppb (dropping to 10 ppb under the 2024 Lead and Copper Rule Improvements). There is no safe level of lead; the 90th-percentile figure describes the system, not your tap — homes with lead service lines or pre-1986 plumbing can be higher.
| Monitoring period | Lead 90th percentile | vs 15 ppb action level |
|---|---|---|
| 2022-01-01 → 2024-12-31 | 0 ppb | Well below the 15 ppb action level |
| 2019-01-01 → 2021-12-31 | 0 ppb | Well below the 15 ppb action level |
| 2016-01-01 → 2018-12-31 | 0 ppb | Well below the 15 ppb action level |
| 2013-01-01 → 2015-12-31 | 0 ppb | Well below the 15 ppb action level |
| 2010-01-01 → 2012-12-31 | 1.3 ppb | Well below the 15 ppb action level |
| 2007-01-01 → 2009-12-31 | 5 ppb | Below the action level, but detectable |
| 2004-01-01 → 2006-12-31 | 0 ppb | Well below the 15 ppb action level |
| 2003-01-01 → 2005-12-31 | 9 ppb | Below the action level, but detectable |
| 2003-01-01 → 2003-12-31 | 9 ppb | Below the action level, but detectable |
| 2001-01-01 → 2003-12-31 | 9 ppb | Below the action level, but detectable |
| 2000-01-01 → 2000-12-31 | 5 ppb | Below the action level, but detectable |
| 1998-01-01 → 2000-12-31 | 0 ppb | Well below the 15 ppb action level |

EPA UCMR5 monitoring, 2023-03-14 to 2024-01-23 · 174 PFAS results at entry points to the distribution system
No PFAS detected. None of the 174 UCMR5 PFAS results for CITY OF NEWPORT BEACH were at or above the method reporting limit. Reporting limits are about 3–5 ppt, so “not detected” means below that threshold — not proven zero.
| Compound | Detects / samples | Max (ppt) | Reporting limit | EPA MCL |
|---|---|---|---|---|
| PFOA | 0 / 6 | < 4 | 4 ppt | 4 ppt |
| PFOS | 0 / 6 | < 4 | 4 ppt | 4 ppt |
| PFHxS | 0 / 6 | < 3 | 3 ppt | 10 ppt |
| PFNA | 0 / 6 | < 4 | 4 ppt | 10 ppt |
| HFPO-DA | 0 / 6 | < 5 | 5 ppt | 10 ppt |
| PFBS | 0 / 6 | < 3 | 3 ppt | hazard index only |
“< 4 ppt” means below the laboratory reporting limit, not zero. ppt = parts per trillion (ng/L). Results are for finished water leaving the treatment plant.
Lithium (also monitored under UCMR5, not a PFAS): detected in 3 of 6 samples, max 36.2 µg/L. There is no federal limit for lithium.

EPA Six-Year Review 4 compliance samples for CITY OF NEWPORT BEACH · finished water only · dated data, released 2024
These are the regulated-contaminant samples CITY OF NEWPORT BEACH reported to its state between 2012 and 2019 — the most recent nationwide sample-level dataset EPA has published. Every scored contaminant stayed within its Maximum Contaminant Level (MCL) and averaged below 80% of the limit. Treat this as history, not today's tap water.
| Contaminant | Samples | Average | Max | EPA limit | Status |
|---|---|---|---|---|---|
| Total trihalomethanes (TTHM) | 248 | 27.813 µg/L | 68 µg/L | 80 µg/LMCL (LRAA) | Within MCL |
| Haloacetic acids (HAA5) | 240179 detects | 8.73 µg/L | 33 µg/L | 60 µg/LMCL (LRAA) | Within MCL |
Averages count non-detects as zero. TTHM and HAA5 limits are locational running annual averages, so a single high sample is not a violation — we grade those on the average only. Lead and copper rows are individual tap samples and are shown for context; compliance (and our score) uses the 90th-percentile result above. LRAA = locational running annual average; ND = not detected.

CITY OF NEWPORT BEACH · 26,413 service lines inventoried · Q2 2026 snapshot
CITY OF NEWPORT BEACH reports no lead or galvanized-requiring-replacement service lines and has classified 100% of its 26,413 lines as non-lead. Lead can still come from pre-1986 plumbing and fixtures inside a home.

Surface-water systems draw from rivers, lakes or reservoirs and must filter and disinfect, which is why disinfection byproducts (TTHM, HAA5) are the readings to watch.
How to test your tap water and the treatment options that actually fit Newport Beach homes
The most reliable way to know what is actually coming out of your tap is a certified mail-in lab test. City-wide EPA data (like the report above) reflects the water leaving the treatment plant, but contaminants such as lead and copper can be picked up from your own service line and household plumbing — so the water at your Newport Beach faucet can differ from the system average. A state-certified lab measures dozens of contaminants at once with results you can trust; you can also find one near you through the EPA's certified-lab list at epa.gov/dwlabcert. Hardware-store test strips are cheaper and instant, but they only screen for a few basics (chlorine, hardness, pH, and a rough lead pass/fail) and are far less accurate — treat them as a first look, not a diagnosis.
Match the treatment to what your test finds. Reverse osmosis (RO) removes the widest range of contaminants — lead, arsenic, nitrate, PFAS, and dissolved solids — which makes an under-sink reverse osmosis system the most thorough choice for Newport Beach households with heavy-metal or PFAS concerns. If your main issue is taste, odor, or chlorine, an activated carbon filter (pitcher, faucet, or under-sink) is simpler and cheaper and handles chlorine and many organic compounds well, though carbon alone does not remove arsenic, nitrate, or most PFAS. NSF-certified pitchers rated for lead reduction are the easiest way to start today while you decide on a permanent setup.
