Lead & Copper Testing

Lead (Pb)

90th percentile of tap samples collected across the distribution system

0% of EPA action level

Not detected

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.

104.6% of EPA action level

1,360 ppb

Action level: 1,300 ppb

Lead was not detected at the 90th percentile — the result fell below the laboratory detection limit. That is not the same as an absence of lead in every tap, and older homes with lead service lines can still show higher readings. Copper reached the action level here; a copper figure appears in SDWIS only when a system triggers it.
