Lead & Copper Testing

Lead (Pb)
90th percentile of tap samples collected across the distribution system
17% of EPA action level
2.60 ppb
Action level: 15 ppb
The 90th-percentile lead result is 2.60 ppb, 17% 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.
