Lead & Copper Testing

Lead (Pb)
90th percentile of tap samples collected across the distribution system
100% of EPA action level
54.50 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.
338.5% of EPA action level
4,400 ppb
Action level: 1,300 ppb
The 90th-percentile lead result is 54.50 ppb, 363% 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.

Consider a filter certified for lead
Look for NSF/ANSI 53 certification for lead reduction.
2

Lead reaches tap water mainly through service lines and household plumbing. Suppliers now publish an inventory identifying lead lines.
3
Flush before drinking
If water has sat in pipes more than six hours, run the cold tap for two minutes before drinking or cooking.
