EPA records for LAS VEGAS VALLEY WATER DISTRICT • Updated September 2026
Grade A — based on EPA compliance records, lead testing and PFAS monitoring
LAS VEGAS VALLEY WATER DISTRICT 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.
Yes — by EPA's records Las Vegas, NV tap water is safe to drink and earns an A. The grade rests on low-level PFAS (PFHxA, PFPeA) detected below federal limits. 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.

LAS VEGAS VALLEY WATER DISTRICT's most recent Lead and Copper Rule result (2023-01-01 to 2025-12-31) was 2.08 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.
Yes. EPA's UCMR5 sampling (2025-02-25 to 2025-12-30) detected PFHxA, PFPeA, all below federal MCLs. Reverse osmosis and certified activated-carbon filters reduce PFAS.
LAS VEGAS VALLEY WATER DISTRICT has 33 violations on file since 2016: 0 health-based in the last five years and 0 monitoring or reporting violations in that window. Monitoring violations are paperwork lapses, not measured contamination.
LAS VEGAS VALLEY WATER DISTRICT reports purchased surface water as its primary source and serves about 1,539,277 people (EPA PWSID NV0000090).
Optional but sensible. The findings on this page are below federal limits; an NSF-certified pitcher or under-sink filter handles PFAS and improves taste.

EPA Lead and Copper Rule 90th-percentile results reported by LAS VEGAS VALLEY WATER DISTRICT
Well below the 15 ppb action level. In the most recent monitoring period on file (2023-01-01 to 2025-12-31), 90% of the homes LAS VEGAS VALLEY WATER DISTRICT sampled had lead at or below 2.08 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 |
|---|---|---|
| 2023-01-01 → 2025-12-31 | 2.08 ppb | Well below the 15 ppb action level |

EPA UCMR5 monitoring, 2025-02-25 to 2025-12-30 · 1,711 PFAS results at entry points to the distribution system
PFHxA, PFPeA detected at low levels; no compound was at or above its federal MCL. Detections below the MCL are common in surface-water systems and are reported here exactly as EPA published them.
| Compound | Detects / samples | Max (ppt) | Reporting limit | EPA MCL |
|---|---|---|---|---|
| PFOA | 0 / 59 | < 4 | 4 ppt | 4 ppt |
| PFOS | 0 / 59 | < 4 | 4 ppt | 4 ppt |
| PFHxS | 0 / 59 | < 3 | 3 ppt | 10 ppt |
| PFNA | 0 / 59 | < 4 | 4 ppt | 10 ppt |
| HFPO-DA | 0 / 59 | < 5 | 5 ppt | 10 ppt |
| PFBS | 0 / 59 | < 3 | 3 ppt | hazard index only |
| PFHxA | 2 / 59 | 5.6 | 3 ppt | hazard index only |
| PFPeA | 2 / 59 | 4.8 | 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 50 of 59 samples, max 43.3 µg/L. There is no federal limit for lithium.

EPA Six-Year Review 4 compliance samples for LAS VEGAS VALLEY WATER DISTRICT · finished water only · dated data, released 2024
These are the regulated-contaminant samples LAS VEGAS VALLEY WATER DISTRICT reported to its state between 2012 and 2019 — the most recent nationwide sample-level dataset EPA has published. Total trihalomethanes (TTHM) is flagged below; the status column explains why. Treat this as history, not today's tap water.
| Contaminant | Samples | Average | Max | EPA limit | Status |
|---|---|---|---|---|---|
| Arsenic | 2320 detects | 1.52 µg/L | 3.4 µg/L | 10 µg/LMCL | Within MCL |
| Nitrate (as N) | 78 | 1.592 mg/L | 6.05 mg/L | 10 mg/LMCL | Within MCL |
| Fluoride | 289 | 0.616 mg/L | 0.753 mg/L | 4 mg/LMCL | Within MCL |
| Chromium (total) | 230 detects | 0 µg/L | ND | 100 µg/LMCL | Not detected |
| Uranium (combined) | 41 | 2.202 µg/L | 3.1 µg/L | 30 µg/LMCL | Within MCL |
| Radium-226/228 | 301 detects | 0.029 pCi/L | 0.884 pCi/L | 5 pCi/LMCL | Within MCL |
| Gross alpha | 2117 detects | 2.967 pCi/L | 8 pCi/L | 15 pCi/LMCL | Within MCL |
| Total trihalomethanes (TTHM) | 511 | 54.701 µg/L | 94 µg/L | 80 µg/LMCL (LRAA) | 8 single samples over MCL; average within limit |
| Haloacetic acids (HAA5) | 508499 detects | 26.339 µg/L | 58 µg/L | 60 µg/LMCL (LRAA) | Within MCL |
| Lead (tap samples) | 234 detects | 0.29 µg/L | 2.8 µg/L | 15 µg/Laction level (90th percentile) | Reported, not scored (compliance is on the 90th percentile) |
| Copper (tap samples) | 232 detects | 0.674 µg/L | 8.8 µg/L | 1300 µg/Laction level (90th percentile) | Reported, not scored (compliance is on the 90th percentile) |
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.

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 Las Vegas 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 Las Vegas 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 Las Vegas 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.

Yes — by EPA's records Las Vegas, NV tap water is safe to drink and earns an A. The grade rests on low-level PFAS (PFHxA, PFPeA) detected below federal limits. 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.
LAS VEGAS VALLEY WATER DISTRICT's most recent Lead and Copper Rule result (2023-01-01 to 2025-12-31) was 2.08 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.
