See the record ↓Akiachak's drinking water received a grade of D (46 out of 100), indicating poor water quality. The city's 1 water system serves approximately 627 residents using groundwater.
Lead levels were measured at 6.2 ppb (90th percentile), which is within EPA limits but above recommended levels. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 284 violations on record, including 1 health-based violation. 15 remain unresolved.
Akiachak ranks #57 out of 73 cities in Alaska for water quality, placing it among the lowest-rated in the state. Akiachak relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff. While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection. As a small community water system, Akiachak may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities. The system has seen 132 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

04Where Akiachak's water comes from
Akiachak's drinking water is drawn from underground aquifers through wells.
Groundwater
Underground aquifers reached by wells — naturally filtered, but can carry minerals like arsenic and nitrate.
Local treatment
Groundwater generally needs less treatment — typically disinfection and, where needed, mineral removal.
1 system
1 water system, operated under native american ownership.
627 people
Residents served across Akiachak's service area.
Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals. Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds. The system is operated by native american ownership and serves approximately 627 people through 1 water system.
