Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
lead 2.74 µg/L, below the 15 µg/L action level (detected below the limit); 506 galvanized lines to replace (context, not a tap measurement)
PFBS 16 ng/L, below the 2000 ng/L EPA health advisory (+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 Phoenix, PFAS were detected below their limits, and PFBA 6 ng/L with no federal or state limit; the lead 90th-percentile result was 2.74 µg/L against the 15 µg/L action level. PHOENIX CITY OF (PWSID AZ0407025) has a Purity Score of 90/100 (confidence: high), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap.
PHOENIX CITY OF (PWS ID AZ0407025) is the public water system on record for Phoenix, Arizona, serving about 1,695,000 people. Confirm the utility on your water bill before acting on a specific finding.
Surface water (primary source of record in EPA SDWIS).
In EPA's UCMR 5 testing (2023-01-03 to 2023-12-27), PFBS was detected at 16 ng/L, below the 2,000 ng/L EPA health advisory. PFBA (6 ng/L) was also detected; it has no federal or state limit.
PHOENIX CITY OF's most recent lead 90th-percentile result (2022–2024) was 2.74 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 Phoenix holds 34 findings: 2 above a reference, 4 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.
Phoenix's water is recorded as 14.7 gpg, very hard. Hardness is an aesthetic and plumbing characteristic, not a health-based limit.
