Reviewed Report Rows
Seven reviewed rows from the 2025 report
Measurements, ranges, units, limit fields, status cells, likely-source wording, and table names remain scoped to the named annual-report rows.

Haloacetic Acids (HAA5)
- Likely source listed in report
- By-product of drinking water chlorination
- Source table
- Water Quality Data Table
Preservation and source notes
- The source prints 34 ppb, a 9.3-70.5 ppb range, a 60 ppb MCL, and Violation: No. All cells are preserved without independently calculating compliance or inferring current safety.
TTHMs [Total Trihalomethanes]
- Likely source listed in report
- By-product of drinking water disinfection
- Source table
- Water Quality Data Table
Preservation and source notes
- Violation: No remains limited to this printed 2025 row and is not a current system-wide compliance, advisory, or safety conclusion.
Alpha emitters
- Likely source listed in report
- Erosion of natural deposits
- Source table
- Water Quality Data Table
Preservation and source notes
- The source table prints MCLG `00` and range low `NA`; both are kept reported.
Radium (combined 226/228)
- Likely source listed in report
- Erosion of natural deposits
- Source table
- Water Quality Data Table
Preservation and source notes

Copper - action level at consumer taps
- Likely source listed in report
- Corrosion of household plumbing systems; Erosion of natural deposits
- Source table
- Water Quality Data Table - lead and copper action level section
Preservation and source notes
- Action-level tap-row semantics are preserved; no household-level plumbing claim is inferred.
Lead - action level at consumer taps
- Likely source listed in report
- Corrosion of household plumbing systems; Erosion of natural deposits
- Source table
- Water Quality Data Table - lead and copper action level section
Preservation and source notes
- Action-level tap-row semantics are preserved; no household-level plumbing claim is inferred.
Nitrate [measured as Nitrogen]
- Likely source listed in report
- Runoff from fertilizer use; Leaching from septic tanks, sewage; Erosion of natural deposits
- Source table
- Undetected Contaminants
Preservation and source notes
- The source prints ND and Violation: No but no sample-date cell; those values remain scoped to the named report period without inventing a sampling date.
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 document is titled the 2025 City of Cordova Water Quality Report for PWSID AK2293205 and describes itself as an annual snapshot. Each structured row retains its printed 2025 or 2024 period; the report is not evidence of current conditions at a particular tap.
Source-water description has a count conflict
The report names five surface-water sources on page 1 but later refers to four active sources; Alaska DEC's 2026 monitoring summary also lists four. This page therefore identifies the supported surface-water type without publishing a definitive source count or adopting report-period operational wording as current.
Historical source-water assessment
The report reproduces 2003 source-water assessment results for five named intakes, including Very High susceptibility wording. Those historical assessment labels are context only: they are not contaminant detections, violations, current advisories, or a present safety conclusion.
Report-period SOC waiver
The report says Alaska DEC granted a Synthetic Organic Compounds monitoring waiver for four active sources for the 2023-2025 compliance period and that renewal would be requested afterward. This page does not assert that the waiver remains current or infer compliance from it.
Lead and service-line context in the report
The report says no lead or galvanized-requiring-replacement service lines had been identified so far, while several lines were still categorized as unknown. That report-period statement is not an address-level material finding; readers should use current City and Alaska inventory sources for current information.
Table coverage and sampling periods
The page renders every row from the report's three result tables: four detected-contaminant rows, two 2024 lead/copper action-level rows, and one undetected Nitrate row. The source says some data may be older than one year, so printed sample periods remain attached to individual rows.
Definitions printed in this report
All 16 unit and drinking-water definitions printed on pages 5-6 are reproduced. A definition explains source terminology but does not expand a row's period, create a current standard comparison, or establish current compliance or safety.
Printed status cells remain row-period evidence
The source prints No for all seven rows. Each value remains tied to its named row and printed sample/report period, including the HAA5 range/MCL combination and Nitrate's missing sample date. No independent current compliance, advisory, or safety conclusion is made.
Definitions printed in this report
- ppm
- Parts per million, or milligrams per liter (mg/L).
- ppb
- Parts per billion, or micrograms per liter (µg/L).
- pCi/L
- Picocuries per liter (a measure of radioactivity).
- NA
- Not applicable.
- ND
- Not detected.
- NR
- Monitoring not required, but recommended.
- 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 (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 (Treatment Technique)
- A required process intended to reduce the level of a contaminant in drinking water.
- 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
- State or EPA permission not to meet an MCL or a treatment technique under certain conditions.
- MRDLG (Maximum Residual Disinfectant 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 (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
- Monitored Not Regulated.
- 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 that the concentration of lead and copper must be less than or equal to the action level in at least 90% of the samples collected.

Report identity and field provenance
- Official report document: 2025 City of Cordova Water Quality Report Verified as a six-page PDF with SHA-256 5789de9fcaaa1f54df6e634bee68d4e4d05f553759c34b70e20e5d89eb7ee6d8.
- City-hosted report publication path: City of Cordova 2025 report post The City post links the official annual report; the live public-notice archive remains a separate time-sensitive source.
- CORDOVA CITY WATER and PWSID AK2293205: 2025 City of Cordova Water Quality Report The report title prints PWSID AK2293205 and later identifies CORDOVA CITY WATER.
- Current system identity and source-water-type cross-check: Alaska DEC monitoring summary for CORDOVA CITY WATER The three-page summary is dated February 11, 2026 and identifies AK2293205 as a community surface-water system. Its four-source listing conflicts with the annual report's five-source wording, so no source count is published.
