Understanding Wrangell City and Borough’s Water

Drinking Water Quality Overview

EPA SDWIS

Wrangell City and Borough has limited drinking water data on file. Violation data are unavailable for this county.

Watershed Conditions

EPA ATTAINS

Under the Clean Water Act §303(d), EPA ATTAINS tracks whether waterways meet quality standards for drinking, recreation, and aquatic life (reporting cycle: 2022). A large majority — 82.4% — of assessed waterways are impaired (14 of 17 water bodies) across Wrangell City and Borough's watersheds. The leading impairment causes are fecal coliform and enterococcus. Impairment does not mean tap water is unsafe — it measures ambient waterway conditions upstream of treatment, not finished drinking water.

River & Streamflow Status

USGS NWIS

USGS NWIS gauge data (as of 2026-05-14T10:15:00.000-08:00) puts STIKINE R at 91.9k cfs — running significantly above its long-term average at 165% of mean flow. Streamflow is a leading indicator of drought stress, sediment load, and dilution capacity: low flows concentrate pollutants and warm water temperatures, stressing aquatic life and, in surface-water-dependent systems, the source water quality for treatment plants.

Editorial advisory

What the data suggests for Wrangell City and Borough

Water Verdict

Wrangell City and Borough, Alaska does not have sufficient EPA SDWIS water quality data to determine an overall assessment. Residents should contact their local water utility for the most recent Consumer Confidence Report. Separately, EPA ATTAINS assessments cover 17 water bodies in the county's watershed, with 82.4% listed as impaired under the Clean Water Act — a source-water measure that is tracked independently of tap-water compliance. At the most recent USGS reading, local streamflow was running above its historical mean at 164.8%.

Violation Context

Health-based violation data is not available for Wrangell City and Borough, Alaska. EPA health violations occur when water systems exceed allowable contaminant levels or fail to meet treatment requirements. Residents should request the latest Consumer Confidence Report from their water provider. The most recent Clean Water Act assessment cycle on file for the county's watershed is 2022.

Consumer Guidance

Drinking-water compliance data is not yet available for Wrangell City and Borough in the EPA SDWIS system, which is common for rural areas and census areas served by private wells or small tribal systems. Residents should contact their local utility or state drinking-water agency for the most current Consumer Confidence Report. Using an NSF-certified filter (look for certifications against ANSI/NSF 53 or 58) can provide additional safety margin for any unconfirmed contaminants. Fecal Coliform is the leading impairment cause in Wrangell City and Borough's watershed. A pipeline streamflow snapshot from the STIKINE R gauge is also available on this page.

Regional Context

State-level water quality comparison data is not available for Wrangell City and Borough. When data is available, this section will show how the county's water quality compares to other counties in Alaska.

Advisory text summarizes county-level public records and is not a replacement for your utility's current Consumer Confidence Report or direct local notices.

Frequently Asked Questions

What is the water quality in Wrangell City and Borough, Alaska?
Wrangell City and Borough, Alaska has a drinking-water quality grade of N/A with a score of N/A/100, based on EPA SDWIS compliance data. Compliance data is currently unavailable. Watershed health, monitoring records, and streamflow snapshots are reported separately on this page.
Are there any water violations in Wrangell City and Borough?
Violation data for Wrangell City and Borough is not currently available. Health-based violations indicate instances where contaminant levels exceeded EPA Maximum Contaminant Levels (MCLs).
How healthy are the watersheds in Wrangell City and Borough?
EPA ATTAINS assessments under Clean Water Act §303(d) indicate 82.4% of Wrangell City and Borough's 17 assessed water bodies are classified as impaired (14 impaired). The top reported causes are FECAL COLIFORM, ENTEROCOCCUS, RESIDUES. Impairment means the water body fails to meet state quality standards for at least one designated use — drinking water source, recreation, aquatic life, or fish consumption. Note: watershed impairment doesn't always translate to tap-water issues; treatment plants can remove most regulated contaminants.
What's happening with rivers in Wrangell City and Borough right now?
Wrangell City and Borough's primary USGS streamgage on the STIKINE R has a pipeline snapshot of 91,900 cubic feet per second — 165% of the long-term mean of 55,753.13 cfs. This is well above typical — often a signal of recent precipitation or storm runoff. For the latest gauge feed, visit waterdata.usgs.gov.
How does Wrangell City and Borough water compare to the Alaska average?
Wrangell City and Borough's SDWIS water quality score of N/A/100 is not available for comparison. The average water quality grade across Alaska is F, based on data from 22 counties with available SDWIS data.
Is tap water safe to drink in Wrangell City and Borough?
Based on EPA SDWIS data, Wrangell City and Borough has a water quality grade of N/A (N/A/100). Insufficient data is available to fully assess compliance. The grade speaks to the public water system, not the watershed — for watershed-level concerns, see the Watershed Health zone. For the most up-to-date information, contact your local water utility or review your Consumer Confidence Report (CCR).
Does Wrangell City and Borough have clean drinking water?
Wrangell City and Borough has no reported health-based drinking water violations according to EPA records. With a water quality score of N/A/100 and grade N/A, the county's drinking water has had some compliance issues but continues to be monitored. Note: drinking-water compliance speaks to the public water system, not necessarily to the watershed itself — check the Watershed Health zone for ATTAINS §303(d) data.
How is water quality measured?
WaterByCounty layers four federal datasets per county. The A–F drinking-water grade comes from EPA SDWIS (Safe Drinking Water Act compliance, 5-year violation lookback). The Watershed Health zone surfaces EPA ATTAINS §303(d) impairment data. The Monitoring zone summarizes EPA Water Quality Portal records. The Streamflow zone reports the latest USGS NWIS reading from the county's primary streamgage. Each is reported separately so you can see where the water is actually weakest.

Data Sources
