Annual Compliance Reports

Each state is required by the Environmental Protection Agency (EPA) to produce an Annual Compliance Report summarizing the performance of Alaska's public water systems. The reports are made available to the public and the information is included in a national report.

Full Reports

The past 5 years of reports for the State of Alaska are posted below, for older reports please contact the DW Program Manager.

Acronyms on this page

Public Water System (PWS) - A PWS is defined as a system that provides water using piping or other constructed conveyances for human consumption to at least 15 service connections or serves at least 25 people for at least 60 days each year. There are three types of federally regulated PWSs. They can be community (such as villages, trailer parks, or subdivisions); non-transient non-community (such as schools or offices); or transient non-community systems (such as highway rest stops or seasonal state and federal parks).

Maximum Contaminant Level (MCL) Violations - Under the Safe Drinking Water Act (SDWA), the EPA sets national limits on regulated contaminant levels in drinking water to ensure that the water is safe for human consumption. These limits are known as MCLs.

Treatment Techniques (TT) Violations - For some regulations, the EPA establishes treatment techniques in lieu of an MCL to control unacceptable levels of certain contaminants. For example, treatment techniques have been established for viruses, bacteria, and turbidity.

Monitoring (MON) Violations - For this report, monitoring violations are generally defined as any major monitoring violation that occurred during the calendar year of the report. A major monitoring violation, with rare exceptions, occurs when no samples were taken or no results were reported during a compliance period.

Other Violations - For this report, violations defined as "other" refer to a reporting violation, RTCR Sample Siting Plan violation, or a violation for not completing a Sanitary Survey inspection on time during the calendar year of the report.
