From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit.
Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
lead 2.08 µg/L, below the 15 µg/L action level
PFHxA 5.6 ng/L, below the 400000 ng/L state limit (+1 more PFAS detected)
Screening tells you if something is worth a closer look; a lab result is the number you can act on.

Screening: quick check, not lab-grade
Varify
17 strip readings, including lead, chlorine, fluoride, iron and hardness, plus 2 coliform bacteria tests
What it can't tell you: Strip colors give rough ranges, not lab numbers, and it cannot detect PFAS or arsenic.
Lab-certified results
ETR Laboratories
50+ substances, including lead, copper, arsenic, nitrate, hardness and coliform bacteria
What it can't tell you: It does not test PFAS, and not every result on the panel falls under the lab's accredited scope.

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Las Vegas, PFAS were detected below their limits, and PFPeA 4.8 ng/L with no federal or state limit; the lead 90th-percentile result was 2.08 µg/L against the 15 µg/L action level. LAS VEGAS VALLEY WATER DISTRICT (PWSID NV0000090) has a Purity Score of 85/100 (confidence: high), assessed at the water-system level and computed only from contaminants that were measured.

Surface water (primary source of record in EPA SDWIS).
In EPA's UCMR 5 testing (2025-02-25 to 2025-12-30), PFHxA was detected at 5.6 ng/L, below the 400,000 ng/L state limit. PFPeA (4.8 ng/L) was also detected; it has no federal or state limit.
LAS VEGAS VALLEY WATER DISTRICT's most recent lead 90th-percentile result (2023–2025) was 2.08 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.
PurityMap's current record for Las Vegas holds 38 findings: 2 above a reference, 8 detected within the reference, 1 detected with no limit and 27 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
Las Vegas's water is recorded as 16.4 gpg, very hard. Hardness is an aesthetic and plumbing characteristic, not a health-based limit.
