Drinking-water testing
Los Angeles Department of Water and Power · CA1910067. These are public water-system records, not a test of the tap water at your home.
PFAS testing

PFOS
Not detected above reporting limit
- Sample date
- Reporting limit
- 0.004 µg/L
- Sample ID
- 380-112903-1
Selected latest compound samples from the published federal system record. Multiple sample points may share a date. A detection does not establish a violation. A non-detection does not mean PFAS-free. PFOA and PFOS limits and regulatory context are separate from these historical samples.
Lead and copper
Lead: 0.0039 mg/L, period ending 2023-12-31. These are system 90th-percentile results, not individual household concentrations.
Drinking-water compliance
No current violations flagged; past records available. 0 current flags and 7 historical records in the federal publication dated September 1, 2026. Historical records are not all active violations.

Drinking-water testing and compliance
Compliance records, PFAS sampling, and lead and copper results answer different questions. None is a test of a particular home's faucet.

No current violations flagged; past records available
This means no current violation is flagged in this snapshot. It does not prove that every tap is contaminant-free.

Compliance history
7 violation records
Federal and primacy-agency regulatory history reported in EPA ECHO/SDWIS; not a household tap-water test.
PFAS / UCMR5
No PFAS detection above the reporting limit in these results
464 compound results in the 2023–2026 UCMR5 final release. Non-detection means not detected above the reporting limit in that sample—not that PFAS never occurs.
Lead & copper
25 system-level results
System-level lead/copper 90th-percentile reporting; not the lead or copper level at a particular faucet. This system-wide inventory does not identify the pipes at your address.

Detection is not the same as violation.A reported detection is not, by itself, a drinking-water violation or a statement about a household tap. EPA states UCMR results do not indicate compliance or noncompliance with PFAS MCLs.
