Lead & Copper Testing

Lead (Pb)

90th percentile of tap samples collected across the distribution system

11% of EPA action level

1.61 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.

116.4% of EPA action level

1,513 ppb

Action level: 1,300 ppb

The 90th-percentile lead result is 1.61 ppb, 11% 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.
