What the violations mean
Total Trihalomethanes (TTHMs)
13 incidentsDisinfection byproduct levels exceeded the federal limit
Long-term TTHM exposure may increase bladder cancer risk
Haloacetic Acids (HAA5)
7 incidentsHaloacetic acid byproducts exceeded the federal limit
Long-term exposure to HAAs may increase cancer risk
Revised Total Coliform Rule
2 incidentsThe system did not meet a requirement of the Revised Total Coliform Rule
Coliform and E. coli rules protect against bacteria in the distribution system
Where the water comes from
Aunuu Asg draws water from 2 wells (1 of them for emergency, seasonal or other part-time use).
Annual water quality report
Aunuu Asg 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 Aunuu Asg 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 American Samoa.
