Public drinking-water record

Drinking-water testing

Las Vegas Valley Water District · NV0000090. These are public water-system records, not a test of the tap water at your home.

Selected latest compound samples from the published federal system record. Multiple sample points may share a date. A detection does not establish a violation. A non-detection does not mean PFAS-free. PFOA and PFOS limits and regulatory context are separate from these historical samples.

Lead and copper

Lead: 0.00208 mg/L, period ending 2025-12-31. These are system 90th-percentile results, not individual household concentrations.

Drinking-water compliance

No current violations flagged; past records available. 0 current flags and 49 historical records in the federal publication dated September 1, 2026. Historical records are not all active violations.

Drinking water & contaminants

Drinking-water testing and compliance

Compliance records, PFAS sampling, and lead and copper results answer different questions. None is a test of a particular home's faucet.

Recency unconfirmed · Date unavailableEPA ECHO / SDWIS federal snapshot

The source does not provide a publication date. The last check date is not recorded. This report may not describe conditions today.

EPA ECHO / SDWIS · 2026 Q2 snapshot

No current violations flagged; past records available

This means no current violation is flagged in this snapshot. It does not prove that every tap is contaminant-free.

Compliance history

49 violation records

Federal and primacy-agency regulatory history reported in EPA ECHO/SDWIS; not a household tap-water test.

PFAS / UCMR5

Several PFAS compounds were detected in these samples

1,711 compound results in the 2023–2026 UCMR5 final release. Non-detection means not detected above the reporting limit in that sample—not that PFAS never occurs.

Lead & copper

18 system-level results

System-level lead/copper 90th-percentile reporting; not the lead or copper level at a particular faucet. This system-wide inventory does not identify the pipes at your address.

Water Quality Portal measurements from the surrounding area. More measurements can mean more monitoring—not worse water.

This bounded discovery is not the complete historical record and absence is not evidence of clean water.
UCMR5 PFAS monitoring

54 reported detections

Across 1,770 compound results and 59 samples for this water system.

Detection is not the same as violation.A reported detection is not, by itself, a drinking-water violation or a statement about a household tap. EPA states UCMR results do not indicate compliance or noncompliance with PFAS MCLs.
