Lead & Copper Testing

Lead (Pb)
90th percentile of tap samples collected across the distribution system
4% of EPA action level
0.60 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.
146.2% of EPA action level
1,900 ppb
Action level: 1,300 ppb
The 90th-percentile lead result is 0.60 ppb, 4% 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.
