See the record ↓Fagasa's drinking water received a grade of B (77.6 out of 100), indicating good water quality. The city's 1 water system serves approximately 577 residents using groundwater.
Lead levels were measured at 0.7 ppb (90th percentile), well within EPA limits. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 35 violations on record, including 0 health-based violations. 5 remain unresolved.
Fagasa ranks #1 out of 2 cities in American Samoa for water quality, placing it one of the best in the state. Fagasa 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. As a small community water system, Fagasa may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities. The system has seen 11 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

04Where Fagasa's water comes from
Fagasa'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 state ownership.
577 people
Residents served across Fagasa'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 state ownership and serves approximately 577 people through 1 water system.
