Lead & Copper Testing

Lead (Pb)
90th percentile of tap samples collected across the distribution system
8% of EPA action level
1.20 ppb
Action level: 15 ppb
Copper (Cu)
90th percentile of tap samples. SDWIS reports a copper figure only when a system exceeds the action level, so any value here is an exceedance.
138.5% of EPA action level
1,800 ppb
Action level: 1,300 ppb
The 90th-percentile lead result is 1.20 ppb, 8% of the 15 ppb federal action level. The action level is a treatment trigger, not a legal maximum, and it is measured across sampled taps rather than at any single home. Copper reached the action level here; a copper figure appears in SDWIS only when a system triggers it.

Understanding violation types MCL violations mean a contaminant exceeded the federal maximum limit — the most serious type.
TT (Treatment Technique) violations mean required treatment procedures weren't followed, but don't necessarily mean contamination occurred.

Violation History

315 violations are on record since 2015, of which 4 were health-based. All have been resolved and none remain open.
