Lead & Copper Testing

Lead (Pb)
90th percentile of tap samples collected across the distribution system
11% of EPA action level
1.70 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.
190.8% of EPA action level
2,480 ppb
Action level: 1,300 ppb
The 90th-percentile lead result is 1.70 ppb, 11% 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.

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

284 violations are on record since 2015, of which 37 were health-based. All have been resolved and none remain open.

Frequently Asked Questions

Is Selawik tap water safe to drink? ▼
No federal limit is exceeded on record. No violations are currently open. Lead is 1.70 ppb, 11% of the action level.
Does Selawik water have PFAS? ▼
This system has never been sampled for PFAS. EPA's national monitoring covered systems serving 3,300 people or more, so no results exist — which is not evidence that none is present.
Who supplies water to Selawik? ▼
Selawik Safewater Facility (PWSID AK2340379). Surface water. Drawn from surface water — SDWIS source code SW
When was this system last inspected? ▼
It was last inspected on 2025-06-18. Inspectors recorded 2 significant deficiencies.

What Should Selawik 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.
