What's in Goodyear, AZ tap water
5 contaminants in Goodyear, AZ's water sat at or above a federal limit, led by PFOS (Perfluorooctane sulfonic acid) at 2.0x the limit.
- !5 contaminants at or above a federal limit — worst is PFOS (Perfluorooctane sulfonic acid) at 2.0x
- !2 contaminants within 20% of a limit
- !15 of 27 core regulated contaminants reported — 12 never appear in this report
- ✓No open federal violations
+How this score is calculated
Every system starts at 100. Points come off for measured levels, for the federal violation record, and for how much of the core regulated set the utility actually reported. All three inputs are the utility's own published numbers and EPA's own records.
- −60 contaminants at or above a federal limit
- −8 contaminants within 20% of a limit
- −0 open health-based violations
- −0 open monitoring / reporting violations
- −0 health-based violations resolved in the last 5 years
- −6 core regulated contaminants never reported (15/27)
A 90–100 · B 80–89 · C 70–79 · D 60–69 · F below 60. A system reporting under a third of the core set is capped at C however clean its numbers look — a short report is not a clean bill of health.
Full grading methodology, constant for constant →What to worry about
- PFOS (Perfluorooctane sulfonic acid)2.0× the federal limit7.9 ng/L · limit 4 ng/L
Linked to cancer, thyroid disease, and immune effects; the EPA set an enforceable limit of 4 parts per trillion.
higher than 75% of U.S. systems
- Bromate1.6× the federal limit0.016 mg/L · limit 0.01 mg/L
Classified as a probable human carcinogen; the EPA sets a strict maximum contaminant level.
higher than 95% of U.S. systems
- TTHM1.3× the federal limit104 ug/L · limit 80 ug/L
Long-term exposure above the federal limit is linked to liver, kidney, and central-nervous-system effects and increased cancer risk.
higher than 95% of U.S. systems
- PFOA (Perfluorooctanoic acid)1.2× the federal limit4.8 ng/L · limit 4 ng/L
Linked to cancer, liver damage, and immune effects; the EPA set an enforceable limit of 4 parts per trillion.
higher than 65% of U.S. systems
- Nitrate1.0× the federal limit10 mg/L · limit 10 mg/L
Levels above the federal limit can cause 'blue baby syndrome,' a serious oxygen-transport condition in infants.
higher than 95% of U.S. systems
- Fluoride87% of the federal limit3.46 mg/L · limit 4 mg/L
Beneficial at low levels, but long-term exposure above the federal limit can cause bone disease and tooth mottling.
higher than 95% of U.S. systems
- Arsenic80% of the federal limit8 ug/L · limit 10 ug/L
A known human carcinogen; long-term exposure is linked to skin, bladder, and lung cancer.
higher than 90% of U.S. systems

What this report doesn't tell you
12 of the 27 contaminants a community water system normally reports do not appear anywhere in Goodyear, AZ's data. Absent is not the same as absent-from-the-water — it means nobody published a number.

PFAS — EPA UCMR5 (2023–2025)
2 PFAS compounds above EPA limits in Goodyear, AZ
The EPA finalized the first-ever federal drinking-water limits for six PFAS compounds in April 2024. These numbers come straight from EPA's UCMR5 lab dataset — every U.S. system serving more than 3,300 people tested every PFAS sample at an entry point to its distribution system. PFAS not listed below were either tested and not detected, or not yet sampled.
