Report Context
Context attributed to the source report
These summaries are limited to the named annual report and do not assert live system, compliance, or advisory status.
Annual-report scope
The official document is the MOA MUNICIPALITY OF ANCHORAGE 2025 Consumer Confidence Report, published by AWWU for PWSID AK2210906 in 2026. Its statements and measurements are annual-report evidence, not live status.
Source-water context
The report identifies Eklutna Lake and Ship Creek surface water plus groundwater from six active Anchorage Bowl wells. This is report-period source context rather than a live operating inventory.
Source-water assessment
The report reproduces Alaska DEC susceptibility and vulnerability classifications for named surface-water and well sources. Those assessment categories are not household-tap measurements or current safety findings.
Treatment context
The report describes filtration and disinfection as the system's treatment processes. This summary does not infer a current operating condition or compliance result.
Lead and service-line context
The report describes an ongoing service-line inventory, says no known lead service lines were identified, notes unknown compositions remain, and identifies 2024 lead and copper tap sampling.
Lead and copper sampling context
The report describes 2024 tap sampling on a three-year cycle after at least six hours of standing time. The 90th-percentile rows remain system-level evidence rather than household-tap results.
Complete modeled result scope
This page preserves all 28 printed result rows: fourteen regulated, treatment-technique, action-level, or other rows and fourteen voluntary or secondary rows. The source notes that some required monitoring data may be more than one year old.
Source-water non-detect list
The report lists named inorganic analytes and 23 volatile organic compounds as monitored but not detected in source waters in 2024. They are retained as narrative context rather than invented result rows.
Report-period Total Organic Carbon follow-up
The report says Total Organic Carbon sampling at the source would increase from quarterly to monthly in 2026 to monitor conditions and determine whether additional treatment was needed. Completion or current resolution is not asserted.
Voluntary and secondary table scope
All fourteen page-8 rows are rendered as non-regulatory water-characteristic or secondary-standard evidence with their source units and ranges intact.
Definitions printed in the report
All six unit descriptions on page 8 and all twelve drinking-water definitions on page 9 are transcribed for reading context. They do not create a current compliance or safety conclusion.

- NTU: Nephelometric Turbidity Units. Turbidity is a measure of the cloudiness of the water. We monitor it because it is a good indicator of the effectiveness of our filtration system.
- NA
- NA: not applicable
- ND
- ND: Not detected
- NR
- NR: Monitoring not required, but recommended.
- Contaminant
- Contaminant: Any physical, chemical, biological, or radiological substance or matter in water.
- MCLG
- MCLG: Maximum Contaminant Level Goal: The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.
- MCL
- MCL: Maximum Contaminant Level: The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.
- TT
- TT: Treatment Technique: A required process intended to reduce the level of a contaminant in drinking water.
- AL
- AL: Action Level: The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
- Variances and Exemptions
- Variances and Exemptions: State or EPA permission not to meet an MCL or a treatment technique under certain conditions.
- LRAA
- LRAA: Locational Running Annual Average: The average of analytical results for samples taken at a particular monitoring location in the four most recent calendar quarters.
- MRDLG
- MRDLG: Maximum residual disinfection level goal. The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.
- MRDL
- MRDL: Maximum residual disinfectant level. The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
- MNR
- MNR: Monitored Not Regulated
- MPL
- MPL: State Assigned Maximum Permissible Level
- 90th Percentile
- Compliance with the lead and copper action levels is based on the 90th percentile lead and copper levels. This means the concentration of lead and copper must be less than or equal to the action level in at least 90% of the samples collected.

View How to read a water quality reportReport Disclosures
Source-period disclosures kept separate from live status
These items preserve report wording and scope. They do not create violation records, advisory records, or a current-status conclusion.
Annual report is not current status
The document reports on 2025 and was published in 2026. Its result cells and narrative do not establish current compliance, advisory status, resolution, or conditions at a household tap.
Current status is not asserted. Check official current sources for notices or instructions.
Annual-report assurance is not a live status finding
The official report says AWWU complied with drinking-water regulations and met state and federal standards in 2025. This site attributes that statement to the report period and does not adopt a present-day safety, compliance, advisory, or household-tap conclusion.
Current status is not asserted. Check official current sources for notices or instructions.
Service-line inventory is not property-level proof
The report says no known lead service lines were identified in the MOA system while lines of unknown composition remained. That system-level report statement does not establish the material at a specific property.
Current status is not asserted. Check official current sources for notices or instructions.
System sampling is not a household-tap result
The report's 2024 lead and copper rows are system-level 90th-percentile evidence from selected taps. They do not describe every household tap, service line, or plumbing configuration.
Current status is not asserted. Check official current sources for notices or instructions.
2025 Total Organic Carbon treatment-technique exceedance
The report attributes the exceedance to the 2025 annual average, says July sampling raised that average, says October returned ND while the average still exceeded the treatment technique, and says monthly monitoring would begin in 2026. This is not a claim about current violation, notice, resolution, compliance, or safety status.
Current status is not asserted. Check official current sources for notices or instructions.
Secondary standards are not primary health limits
The report describes the page-8 values as voluntary monitoring and non-mandatory secondary standards used for aesthetic considerations such as taste, color, or odor. This page does not convert them into primary health-based limits.
Current status is not asserted. Check official current sources for notices or instructions.

Report identity and field provenance
- Official annual report document: AWWU 2026 Anchorage Drinking Water Quality Report / 2025 Consumer Confidence Report Verified nine-page PDF with SHA-256 8b9277cbd19766eb2301864f8cc96f298b4ce4f68bc5ee3417ad32cfefdea9ee.
- Report, publisher, PWSID, and year: AWWU 2026 Anchorage Drinking Water Quality Report / 2025 Consumer Confidence Report The document binds MOA MUNICIPALITY OF ANCHORAGE, PWSID AK2210906, the 2025 report period, and AWWU publisher context.
- Current public-water-system identity: Alaska DEC identity record for AK2210906 The state record supports the official PWS name and identifier; AWWU remains operator and publisher context.
- State monitoring-summary context: Alaska DEC monitoring summary for AK2210906 Verified five-page summary with SHA-256 a848621b753952721fb9f82b62096ebf9dee629d236fe8fec13c57912910ee1e; it is used for identity and classification context, not a live notice conclusion.
- Official annual-report archive: AWWU drinking water quality reports The AWWU archive separates the Anchorage and Girdwood reports; Girdwood is excluded from this report contract.
- Official current-information paths: AWWU outages, emergency, water-quality concern, and news paths The linked official paths are places to check current information. Their reviewed state cannot prove that no current notice exists or that current conditions match the annual report.
