Lead & Copper Testing

Lead (Pb)

90th percentile of tap samples collected across the distribution system

76% of EPA action level

11.40 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.

148.5% of EPA action level

1,930 ppb

Action level: 1,300 ppb

The 90th-percentile lead result is 11.40 ppb, 76% 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.

Contaminant Violations (2015–Present)

Contaminant	Type	Measured	Limit	Period	Status
Consumer Confidence Rule	OTHER	—	—	2025	Unaddressed
