Nothing open right now.

On record since 2003: 186 violations. 1 over the limit · 9 treatment lapses · 170 missed or late tests · 6 notices or reports. Most recent began 2025-08-01.

For this year's test results, ask the utility for its annual Consumer Confidence Report. Every community system must publish one.

More violations on record than 94% of active water systems in Alaska. Small systems with no staff chemist often rack up missed-test violations; big utilities rarely do.

One square ≈ 3 violations (rounded up), by the year they began. Empty columns are years with nothing on EPA's record.
<1% over the limit · 15% treatment lapse · 991% missed or late test · 1703% notice or report · 6

Across Alaska, 88% of violations are missed or late tests and 2% are water over a limit.

Lead & copper at the tap

Utilities sample taps in homes most likely to have lead pipes, and report the 90th-percentile result: 9 in 10 homes sampled came in at or below this number. Above the red line (the action level) the utility must act. The action level is not a safe level; EPA's health goal for lead is zero. EPA's file does not date these results, so they are shown highest first.

Reading this record

Shageluk Water System is a community water system that draws from groundwater and serves about 60 people in Shageluk, Alaska. Everything above comes from the EPA's Safe Drinking Water Information System (SDWIS), where states report every violation by every public water system.

Four kinds of violation. Only one is a measurement of the water: over the limit means a test came back above a legal maximum (an MCL). A treatment lapse means a required protective step was not done, such as disinfection, filtration, fixing a defect an inspector found, or filing a lead-pipe inventory. A missed or late test means a required test was skipped or never reported. That is the most common kind, and the most misread: it does not mean the water was bad, and it does not mean the water was fine. Notices and reports covers public notices and the annual Consumer Confidence Report.

Status. “Back in compliance” means the state recorded a return to compliance. “Period ended” means the violation's compliance period is over but no return to compliance was ever filed, which is common in older records. EPA's federal copy lags state records by months, so call the utility for anything current.
