Lead & Copper Testing

Lead (Pb)
90th percentile of tap samples collected across the distribution system
29% of EPA action level
4.29 ppb
Action level: 15 ppb
The 90th-percentile lead result is 4.29 ppb, 29% 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.

Understanding violation types MCL violations mean a contaminant exceeded the federal maximum limit — the most serious type.
TT (Treatment Technique) violations mean required treatment procedures weren't followed, but don't necessarily mean contamination occurred.

Violation History

267 violations are on record since 2015, of which 20 were health-based. All have been resolved and none remain open.

What Should Prospect Residents Do?

1
Read your annual water report
Your supplier publishes a Consumer Confidence Report each July covering the prior year.
2
Check for a lead service line
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.
