36 older violations are not listed here. EPA ECHO has the complete list.

Enforcement actions

Alaska regulators issued 2 boil water orders to Nunam Iqua Water System between 2004 and 2019. The most recent was a boil water order in August 2019.

Date By Action Violations covered
Aug 26, 2019 Alaska Boil water order 1 violation
Dec 2, 2004 Alaska Boil water order 1 violation

What the violations mean

Total Trihalomethanes (TTHMs)

14 incidents

Disinfection byproduct levels exceeded the federal limit

Long-term TTHM exposure may increase bladder cancer risk

CARBON, TOTAL

6 incidents

The system did not complete a treatment step or action that federal rules require for CARBON, TOTAL (a treatment technique violation).

The utility had to notify customers about each of these violations.

Where the water comes from

Nunam Iqua Water System draws water from 1 surface water intake.

Annual water quality report

Nunam Iqua Water System must give its customers an annual water quality report (Consumer Confidence Report) by July 1, with the levels its tests found in the previous year.

Systems serving 500 or fewer people may meet the rule by telling customers the report is available on request, so you may need to ask Nunam Iqua Water System for a copy.

Find a posted report with EPA's Consumer Confidence Report search

Testing your own water

To test the water at your tap, or a private well this record does not cover, use a laboratory certified for drinking water by Alaska.
