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 2.3 µg/L, below the 15 µg/L action level
PFBS 3.2 ng/L, below the 2000 ng/L EPA health advisory
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.

Surface water (primary source of record in EPA SDWIS).
In EPA's UCMR 5 testing (2025-01-13 to 2025-12-01), PFBS was detected at 3.2 ng/L, below the 2,000 ng/L EPA health advisory.
SCOTTSDALE CITY OF's most recent lead 90th-percentile result (2021–2023) was 2.3 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 Scottsdale holds 34 findings: 2 above a reference, 4 detected within the reference and 28 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
Scottsdale's water is recorded as 14.6 gpg, very hard. Hardness is an aesthetic and plumbing characteristic, not a health-based limit.
