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.
128.2% of EPA action level
1,666 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.

TT (Treatment Technique) violations mean required treatment procedures weren't followed, but don't necessarily mean contamination occurred.
