Grade A — based on EPA compliance records, lead testing and PFAS monitoring
PHOENIX CITY OF 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 Phoenix, AZ tap water is safe to drink and earns an A. The grade rests on arsenic averaging 5.1 ug/l against a 10 ug/l limit in 2012–2019 samples (1 over the limit) and low-level PFAS (PFBA, PFBS) 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.

PHOENIX CITY OF's most recent Lead and Copper Rule result (2022-01-01 to 2024-12-31) was 2.74 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 (2023-01-03 to 2023-12-27) detected PFBA, PFBS, all below federal MCLs. Reverse osmosis and certified activated-carbon filters reduce PFAS.
PHOENIX CITY OF has 4 violations on file since 2016: 0 health-based in the last five years and 2 monitoring or reporting violations in that window. Monitoring violations are paperwork lapses, not measured contamination.
PHOENIX CITY OF reports surface water as its primary source and serves about 1,695,000 people (EPA PWSID AZ0407025).
Optional but sensible. The findings on this page are below federal limits; an NSF-certified pitcher or under-sink filter handles PFAS, arsenic and improves taste.
PFBA, PFBS were detected in Phoenix's water at low levels in 2023–2025 EPA monitoring.
Best for Arsenic Removal
APEC Reverse Osmosis System
Reverse osmosis removes arsenic to safe levels — the EPA-recommended treatment for arsenic (carbon pitchers don't remove it).
