PFAS — EPA UCMR5 (2023–2025)
2 PFAS compounds above EPA limits in Glendale-city, Water Dept., CA
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.

People also ask about Glendale-city, Water Dept., CA's water
+Is Glendale-city, Water Dept., CA tap water safe to drink in 2026?
The 2026 Consumer Confidence Report for the Glendale-city, Water Dept., CA water utility lists 4 contaminants at or above the federal limit: Tce, Pce, 1,2,3-TCP, and Carbon Tetrachloride. Whether that means the water is "unsafe" depends on which contaminant, how long the exposure, and individual health factors. The table on this page shows the measured value, the federal threshold, and the regulated statistic used for compliance.
+What contaminants are in Glendale-city, Water Dept., CA tap water?
118 contaminants were measured in Glendale-city, Water Dept., CA's 2026 Consumer Confidence Report, spanning other, metals, and pfas ("forever chemicals"). 75 have an enforceable federal limit; the rest are detected but unregulated. Every measured value, in the utility's own units, is on this page.
+Which contaminants exceed federal limits in Glendale-city, Water Dept., CA tap water?
4 contaminants in Glendale-city, Water Dept., CA's 2026 report sit at or above the federal limit: Tce (10.9× the limit); Pce (7.9× the limit); 1,2,3-TCP (3.1× the limit); Carbon Tetrachloride (1.4× the limit). The EPA enforces these limits against the regulated reporting statistic — typically a running annual average or 90th percentile — not a one-off sample spike.
